      high germination rate and vigorous early growth under salty soils is preferred. In this study germination and seedling growth of a canola (Brassica napus L.) cultivar (Hayola 401) was assessed using in a factorial laid out in three separate experiments as Completely Randomized Design (CRD) testing combinations of four levels of salinity (0, 80, 160 and 240 mMol NaCl) and three levels of salicylic acid (0, 0.5 and 1 m gr Lit) in the first experiment, the same salinity levels with four levels of gibberellic acid (0,1.5, 3 and 4.5 m Mol) in the second experiment and the same salinity levels with four levels of abscisic acid (0, 2, 4 and 6 m Mol Lit) in the third experiment. Results showed that germination percentage and germination rate was significantly increased by salicylic acid (SA) and gibberellic acid (GA) under salinity conditions compared to non-treatment of these two hormones. Priming with SA could not improve radicle length and radicle dry weight in all salinity levels. Application of GA enhanced radicle and hypocotyl length in all salinity levels compared to untreated seeds with treatment. ABA decreased germination percentage to about 12 % in 2 m Mol than control. Priming with ABA could not improve radicle length in all salinity levels. Seeds primed with ABA improved dry weight of seedlings as compared to non-treatment of ABA under non salinity and salinity conditions. In general, tolerance to salinity in canola seed increased with SA, GA and ABA compared to control. Manuscript profile

      The recent research was carried out in order to evaluate effects of salt stress on growth and some physiological traits of four spring canola cultivars (Brassica napus L). canola cultivars were Hyola401, Hyola308, Hyola60 and RGS003 and salt stress treatments were applied using salt solutions with EC values of 0 (control), 4, 8 and 12 dsm-1. The experiment was conducted as factorial in basis RCBD with three replications in Dezful research station in Safi Abad, 2010-2011. The results showed that salt stress caused significant decrease in photosynthesis, chlorophyll content, dry matter weight per plant and grain yield per plant. Salt stress effects on traits such as stomatal conductance and relative water content of leaf that caused decrease in photosynthesis and dry matter weight per plant, plant height, grain weight per plant and grain yield in plant. The study showed that the use of some traits such as photosynthesis rate and chlorophyll content that have positive correlation with dry matter weight per plant and grain yield per plant may have been suggested as an important selection criterion for salt-tolerance in brassica.

      In order to investigate the effect of planting date and harvest time on the morphological traits of forage maize (cv. Karoun 701), an experiment of split plot in randomized complete block design with three replications was conducted in Varamin in year of 2015. Treatments included five planting dates as main factor (9th of April, 21th of May, 18th of June, 30th of June and 15th of July) and two harvesting times as sub-factor (milky stage and dough stage). The result showed that the effect of planting dates had significant at 1% level on the plant height, leaf width, leaf area, cob diameter and fresh yield. But had no significant effect on the number of leaf per plant, leaf length, number of internode per plant and stem diameter and were not affected by planting date. Results of this experiment showed that planting date of 30th of June was superior to other planting dates in terms of morphological traits such as plant height, leaf width, leaf area, cob diameter and fresh yield of plant compared to other planting dates, and the amount of the above traits with early and delay in planting are greatly reduced. In between, harvesting time at milky stage had the highest leaf width and leaf area and harvesting at dough stage had the highest fresh yield of plant. It is recommended to obtain optimum corn yield, sowing operations should be carried out in the first half of July in Varamin region and for harvesting quality forage at milky stage and to obtain greater harvest yield at dough stage.

      In order to evaluate the yield and yield components of pinto bean varieties (Phaseolus vulgaris L.), under water stress, an experiment was conducted in 2016 in Damavand city in the form of a split plot design based on a randomized complete block design with 3 replications. So that water stress (A), as the main factor, includes three levels: control, mild stress and severe stress and variety (B) was considered as a subfactor, including 6 varieties of pinto beans (Ghaffar, F16, Ks21492, Ks21495, Ks21558 and Ks22102). The traits of number of pods per plant, length of pods, number of seeds per pod, weight of 100 seeds, biological yield, yield of seeds per plant and harvest index were measured and indices of drought stress tolerance were calculated. According to the results of analysis of variance, the effect of water deficit stress was significant on all studied traits, except for the traits of weight of 100 seeds, biological yield. Also, there was a significant difference between the investigated varieties in terms of all the studied traits at the probability level of 1%. The results of comparing the mean treatments showed that Ks 21495 had the highest seed yield with the highest values of the number of pods per plant and the number of seeds per pod. Based on the obtained results, mean productivity (MP), geometric mean productivity (GMP), harmonic mean (HARM) and stress tolerance index (STI) indices were the most appropriate indices for the strain-tolerant varieties.

      In order to determine the most appropriate planting distance and cultivar and also to find the most effective traits in watermelon yield at different planting densities, this study was conducted as split plots in three replications for two cropping years 2016-2017 in Jiroft. Plant spacing (40, 50, 60 and 70 cm) and four watermelon cultivars (Patangra, Favorite, CrimsonPS and CrimsonG-53 were divided into main and sub-plots, respectively. There was a significant effect on the studied traits except the thickness of the fruit skin, so that the number of fruits and yield decreased significantly with increasing plant distance on the planting line; The highest values of these traits were 0.99 and 23.82 tons.hectare-1 at a distance of 40 cm, respectively. But the quality and appearance of the fruit at a distance of 70 cm had its highest value. Increasing the culture distance from 40 to 70 cm increased the amount of soluble solids by 12%. The studied cultivars were significantly different in all traits except Brix. CrimsonPS and CrimsonG cultivars had the highest yields during the two years of testing at 22.50 and 20.76 tons per hectare, respectively. CrimsonPS cultivar was relatively superior to other cultivars in terms of most of the studied traits, and this ultimately led to the highest yield per unit area. Path analysis showed that in different cultivation densities, fruit number and single fruit weight had the greatest effect on fruit yield; These two traits were selected as the most important traits in determining fruit yield.

      In recent years, two times cultiviation in year, or rice replanting, has gained popularity in Haraz watershed basin. In order to determine the interactive effect of planting date and variety on growth index, yield, yield components, and percent of blast desease in Tarom Mahali, Binam and Koohsar varieties in replanting cultivation, a field experiment was carried out at the Deputy of the Rice Research Institute of Iran, Mazadaran branch (Amol), in 2015 and 2017.Experiment was laid out as a split plot base complety random block design with three replications, where planting dates, as main plot, included 24 July, 2 and 12 AugustandTarom Mahali, Binam and Koohsar varietieswere put in sub-plots.Plot size was 3×4 m2 with a plant spacing of 20×20 cm2, and 2-3 seedlings per hill.Agronomical characterestics were measured at three growth stages, namely maximum tillering, flowering and physiological maturity. Results showed that tiller and panicle number per hill was higher in third planting date. SPAD value was affected by variety and Koohsar had highest SPAD value in all planting dates. Highest crop growth and net assimilation rate was obtained in Koohsar variety at flowering satge. The Highest yield was obtained in the second planting date for Koohsar and Binam varieties, though percent of blast disease incidence was higher as well. The higher yield of Koohsar variety could be attributed to having higher grain weight and harvest index compared to Tarom Mahali variety. Based on the results, best planting date would be from 2 to 12 August of in Haraz watershed basin. Manuscript profile

      This research was conducted in order to investigate the effect of iron nanoparticle (INp) and Putrescine (Pu) on some Camelina traits as a factorial design in a randomized complete block design with three replications at Baye-Kola Agricultural Research Station (BARS) in 2021. The treatments included INp (0, 20, 40 and 60 ppm) and putrescine (0, 0.5, 1 and 1.5 mM). Variance analysis showed that the factors were significant on the amount of photosynthetic pigments and morphological traits. The results of the comparison of the simple effect of the treatments showed that the highest amount of chlorophyll a and carotenoid was in the vegetative stage and carotenoid in the reproductive stage at 60 ppm of INp and the highest amount of chlorophyll a at 1 mM Pu and the highest am ount of carotenoid at 1.5 mM Pu. The highest amounts of chlorophyll b and total pigments were observed in the vegetative stage in the treatment combination of 40 ppm INp with 1.5 mM Pu and in the reproductive stage in the treatment combination of 60 ppm INp with 1 mM Pu. The highest amount of yield, number of seeds per capsule and also, the high value of 1000 seed weight and plant height were observed in the treatment combination of 40 ppm INp with 1 mM Pu. In general, the interaction effect of 60 ppm of INp and different concentration of Pu had the best results, and the spraying of these stimulants can improve the yield of the Camelina plant.

      Salt stress is one of the major a biotic stresses especially in arid and semi-arid regions. This investigation was conducted to evaluate the effects of the salt stress on APX and SOD activities in safflower genotypes based in a factorial experiment as a randomized complete block design (CRD) with three replications. The experimental factors were six genotypes of safflower (Arak, Isfahan, Khorasan, C111, AC-stirling and Saffire) and five levels salt stress (0(control), 50, 100, 150 and 200Mm NaCl). There was a significant difference between genotypes in activity of SOD and APX enzymes under salt stress, with notable superiority of Isfahan genotype over other genotypes. Maximum activity of SOD was 99.16 uni/g Fw for Isfahan genotype under 150 Mm NaCl. In general, it seems that Isfahan genotype had more tolerance to salinity and AC-stirling was sensitive to salt stress. The results showed that Isfahan genotype had the greatest APX activity with 91unit/gFW while AC-stirling has the lowest content with 58unit/g FW at control treatment. The activity of both enzymes increased with salt stress, that this increase was dependent on genotype. APX and SOD activity decreased at the 200 Mm NaCl concentrations. The reason for declining in enzyme activity may be returned to enzyme protein damage by high salt stress or adaptation of plants to salt stress. Analysis of seedling traits showed that similar to antioxidants context, the genotypes of Isfahan and Ac-sterling had the most and the least values for all of the studied traits. The result showed that Isfahan genotype could be proposed for salt breeding programs in safflower. Manuscript profile

      In order to investigate the effect of sowing date on yield and yield components of soybean, an experiment was carried out at split-plot in a randomized complete block design with four replications under Sari region in 2009-2010. The main plot was sowing dates including on 5th June, 20th June and 5th July and sub plot was three cultivars including JK, 033 and Telar. Results showed the most of pod weight per plant, pod number per m2, stem weight per hectare, grain yield per hectare, straw yield per hectare and biological yield per plant were obtained on 20th June. Small pods were observed in 5th June and the lowest pod weight per plant, pod number per m2, straw yield per hectare and biological yield per plant were obtained on 5th July. Telar cultivar had been the most grain yield per hectare and biological yield per plant, but highest pod height were the most in JK cultivar. The maximum of pod weight per plant, stem weight per hectare, grain yield per hectare, straw yield per hectare and biological yield per plant were observed at the interaction of planting date on 20th June and JK cultivar. Becuase of the fact that yield and yield comonents increased in 20th june, this treatment was the best sowaing date. Manuscript profile

      Estimation of genetic diversity, combining ability and heterosis of maize inbred lines for breeding aims are very important and would determine breeding strategies. In order[dfp1]  to estimate potential genetic Iranian corn inbred lines using diallel and AMMI methods, fourteen corn inbred lines cross were studied according to diallel scheme. Parents and their hybrids were evaluated in 2007 at Seed and Plant Improvement Institute, Karaj, using Randomized Complete Block design with three replications. Results indicated that Significant differences (p<0.01) were observed among the genotypes for all studied traits, therefore Griffing’s method 2, model 1 was chosen for subsequent diallel analysis. Variances due to GCA and SCA were significant for all studied traits (P < 0.01). Results indicated that for number of kernel row per ear, 100 seed weight, cob percent and kernel moisture percent additive gene effects were more important than the non additive ones, but for grain yield, plant height, ear height, ear diameter, number of kernel per row and number of kernel per ear non additive gene effects were more important than the additive ones. For ear length and kernel weight per ear, importance of additive and non additive gene effects was the same. The best AMMI model for yield was AMMI3 explained 75.6% of interaction variance. The best general combinatory for yield were K166B, K3615/2 and K3653 lines. The highest specific combining ability and mid-parent heterosis for yield according to Griffing, first and second AMMI components, was observed in MO17 × K3653, K166B × K3653, K166B × K3653, A679 × K3544/1 and K3653 × K3493/1.  [dfp1]این رو فقط یه نگاه کلی کنید ممنونم Manuscript profile

      In order to investigate the effects of different mycorrhizal fungi and phosphorus fertilizer on growth traits and grain yield of wheat, an experiment was conducted in factorial experiment in a completely randomized design with three replications. The first factor included mycorrhizal fungi application as non-use of fungi (control), Glomus intraradices, Glomus mossea and Glomus fasciculatum and the second factor included various levels of phosphorus fertilization included non-application of fertilizer (control), 40, 80 and 120 kg ha-1. The results showed that the effect of fungi, phosphorus fertilizer and interaction between the application of fungi and phosphorus fertilizer on leaf area index, dry matter, root dry matter and grain yield were significant. In all treatments of mycorrhizal fungi with increasing of phosphorous fertilizer level, leaf area index, total dry matter, root dry matter and grain yield increased. Maximum values in all studied traits were observed under the application of Glomus intraradices and Glomus mossea. Glomus mossea and Glomus intraradices at 80 kg ha-1 fertilizer level was the best condition for all traits. But in Glomus fasciculatum, the maximum of traits was obtained at 120 kg ha-1 fertilizer. In general, using Glomus mossea and Glomus intraradices can reduce the use of phosphate fertilizers, which could be a new approach to achieve sustainable agriculture. Manuscript profile

          This research carried out in a field factorial experiment based on randomized complete block design with three replications in Rasht at 2016-17 growing season. Experimental factors were including two levels of Pseudomonas fluorescent (seed inoculationand uninoculation) and six levels of phosphate fertilizer from super phosphate triple source (0, 30, 60, 90, 120 and 150 kg/ha). Pseudomonas effect was significant on pod length, number of seed per pod, number of pod per plant, hundred seed weight, dry seed yield, harvest index and phosphorous seed content (P≤ 0.01). Effect of phosphate fertilizer was significant on number of pod per plant, hundred seed weight, dry seed yield, harvest index and phosphorous seed content (P≤ 0.01). Interaction effects of two factors were significant on all of the studied traits except of harvest index (P≤ 0.01). The highest value of phosphorous seed content (355 ppm) was observed in combination treatment of 150 kg P/ha and Pseudomonas inoculation. Seed yield was 3893.3 kg/ha in combination of seed inoculation with Pseudomonas and phosphate fertilizer (90 kg/ha), which there was no significant differences with 120 and 150 kg P/ha. This fertilizer combination increased 38 percent seed yield in comparison to 90 kg/ha phosphate fertilizer and uninoculation of Pseudomonas bacteria. Overall, the inoculation with Pseudomonas bacteria and phosphate fertilizer (90 kg/ha) could achieve seed yield potential, reduce the adverse environmental impacts and save the P-fertilizer utilization.

      In order to investigate the effect of integrated weed management on yield and yield components of maize (SC704) an experiment was conducted at the research field of Shahrood University of Technology as randomized complete blocks design with four replications. The treatments were; weed free, weedy, recommended herbicide dose (nicosulfuron 80 g.a.i. ha-1), hydro priming + reduced herbicide dose (nicosulfuron 40 g.a.i. ha-1), hydro priming + weeding 6 weeks after crop emergence, hydro-priming, hydro-priming + priming with salicylic acid + reduced herbicide dose, priming with salicylic acid, priming with salicylic acid + weeding, priming with salicylic acid + reduced herbicide dose, hydro-priming + priming with salicylic acid + weeding. The results indicated that no significant difference was observed in density and biomass of weeds between the combinations treatments (priming with salicylic acid + reduced herbicide dose and hydro-priming + priming with salicylic acid + weeding 6 weeks after emergence) and herbicide recommended dose treatment. Hydro-priming + reduced herbicide dose increased the biological yield by 25 and 45 percent in comparison to herbicide recommended dose and weed free treatments, respectively. The results indicated that hydro priming + reduced herbicide dose and priming with salicylic acid + reduced herbicide dose of nicosulfuron increased grain yield by 45.3% in comparison to weedy treatment. Based on the results of this experiment, seed priming in combination with reduced dose of herbicide and or with weeding, can effectively control weeds and increase crop yield and also reduce herbicide consumption.

      In order to investigate the effect of soil amendments on yield components, yield and oil percentage of rapeseed (Brassica napus L.), a field experiment was conducted as a randomized complete block design with three replications at the farmer's field located in Amol during 2021. The experimental treatments include the application of soil amendments at eight levels of control or non use of amendments, biochar, silicon nanoparticles, zinc nanoparticles, biochar + silicon nanoparticles, biochar + zinc nanoparticles, silicon nanoparticles + zinc nanoparticles, and the application of biochar + silicon nanoparticles + zinc nanoparticles. The results indicated that the application of all soil amendments improved the yield components, yield and oil content of rapeseed compared with the control treatment or non-use of amendments. In general, the combined application of amendments had better impacts on the studied traits than the individual application of each amendment. Also, among the individual treatments, the application of zinc oxide nanoparticles had the greatest effect in improving yield components and seed yield. The highest plant height (144.33 cm), number of silique per plant (240) and seed yield (3263.7 kg.ha-1) were obtained when all three amendments were used simultaneously. No statistically significant difference was observed between individual and combined treatments of amendments in terms of seed oil content. According to the results of the present study, the simultaneous use of soil amendments can have an effective role in improving the quantitative and qualitative characteristics of rapeseed.

      Salinity stress is a major problem of limiting agricultural productivity and plant growth in many regions of the word including south-west Iran. There are various practices that can apply including Improvement of saline soils and irrigation management and introduction of toleratedcultivars. The aim of experiment is introducing tolerant and semi tolerant cultivars in many regions for acceptable crop yields. Breeding for salinity tolerance, pot experiment under natural conditions in a completely randomized design and enforced in three replications in three states in a stress, fourteen ds/m and twenty-one ds/m. Genotypes were evaluated for salinity tolerance by using dry matter of grain, seed number, grain yield, 1000-grain weight, and relative water content, leaf Na+, leaf K+, leaf K+/Na+. Sirvan cultivar at both salinity levels 14 (17.30 mg/g) and 21 (28.43 mg/g) ds/m, had the highest amount of leaf sodium and aflak cultivar (8.70 mg / g dry weight), had the lowest sodium concentration under 21 ds/m salinity stress. According to the results, among the genotypes studied, aflak as resistant cultivar, Sirvan as susceptible and Arg cultivar as a medium were selected from varieties adapted to Khouzestan conditions.

      Wheat is one of the most basic and important sources of nutrition in the world. Finding a solution to reduce the effect of drought stress on its quantitative and qualitative performance can help countries to achieve greater food security. In order to investigate the effect of silicon on agro physiological properties of wheat under drought stress, this experiment was conducted as a factorial in a randomized complete block design with three replications. During two cropping years 2019-2020 and 2020-2021 It was carried out in the research farm of Karaj Soil and Water Institute Experimental treatments include drought stress at three levels without stress, mild stress and severe stress with 75, 50 and 25% of soil moisture usable as the first factor, respectively. And potassium silicate in four levels of non-use of control silicon and 20 kg , ha as soil used in stemming and concentrations of 2.5 and 5 kg , ha foliar application in stem stage, spike emergence and pasteurization stage as the second factor of cultivar was implemented in two years. The results of analysis of variance showed the effect of drought stress and silicon on grain yield, spike length, stem diameter, plant height, chlorophyll a concentration were significant. The results showed that in the interaction of non-drought stress with foliar application of 5 kg , ha, the best grain yield was 7892.00 kg. Based on the results of the present study, it seems the application of silicon as soil application and foliar application has improved grain yield. Manuscript profile

      Salinity is one of the most important issues that significantly reduce the area of arable land and also the amount of production and product quality. Identification and domestication of salinity-resistant plant species which have economic value is an important strategy. This study was conducted for evaluation of oil percent and fatty acids content in some wild halophyte’s plants. The results showed that the highest percentage of oil (14.20%) was obtained in Salicornia saline plant and the lowest amount (2.65%) was obtained in Halostachys caspica salinity plant. The highest levels of palmitic acid, stearic acid and linolenic acid were observed in Halostachys caspica. The highest amount of linoleic acid was obtained in Salicornia, Anabasis setifera and prickly pear plants and the lowest amount was obtained in Halostachys caspica. The highest total of saturated fatty acids was obtained in Halostachys caspica plant. The highest total of unsaturated fatty acids was observed in Salicornia and saline plants. In general, the results of this study showed that the use of halophyte species as a source of vegetable oil is economical, because these plants do not compete on quality soil and water with conventional crops. In addition, the percentage of unsaturated fatty acids in all studied species except Halostachys caspica was shown to be high and equal to most oilseeds. Due to the ability of these plants to grow in saline soils, they can be used as a resource of oil extraction in this condition. Manuscript profile

The effects of cadmium (Cd) and lead (Pb) on the growth of roots and aerial parts, and the number of flowers in Matricaria chamomilla L. were investigated in greenhouse and field conditions using 10-kg pots containing polluted soil with Cd (0, 10, and 40 mgkg-1) and Pb (0, 60 and 180 mgkg-1) in 2018-2019 in Isfahan (Khorasgan) Islamic Azad University. The effects of the experimental treatments including metal concentration was significant at 5% level, growth stage and location, plant tissue and their interactions significantly affected plant growth (dry weight) was significant at 1% level. Increasing Cd and Pb concentrations decreased number of flowers in the field and increased it in the greenhouse. Plant growth significantly decreased by increasing heavy metal concertation was significant at 5% level as at the first, second and third contamination levels, it was equal to 480.39, 416.00, and 399.33 g, respectively. The highest plant growth was resulted at flowering (500.78) and tillering (511.67 g), significantly at 5% level higher than that of stemming (283.28 g). Compared with Pb (407.44 g), increasing Cd concentration, resulted in significantly at 5% level higher reduction (333.11 g) of plant growth. It is possible to grow Matricaria chamomilla L. in heavy metal polluted soils for the bioremediation of the environment. Manuscript profile

      In order to evaluate the effect of green gram (Vigna radiata) sowing date as a green manure in combination with different rates of nitrogen (N) and phosphorous (P) fertilizers on wheat grain yield and light extinction coefficient, a field experiment was conducted in Dezful during 2008-2009. The experiment was split-plot factorial based on RCBD with three replications. Main plot consisted of green gram sowing dates were 30th June and 10th August, besides to fallow and three rates of N (0, 60 and 120 kg ha-1) and P (0, 45 and 90 kg ha-1) were in sub-plots. Results indicated that the application of green manure increased soil organic matter and inorganic nutrients. The highest light extinction coefficient (K) found on 30th June. A significant increase in nitrogen rate led to more light extinction coefficient because of  higher LAI. In comparison to fallow treatment, the green manure sowing dates on 30th June and 10th August led to more grain yield by 15.3% and 3.1% respectively. Delaying in green gram sowing date reduced the benefit effects of the green manure in wheat grain yield. Generally, the results of this investigation showed that, sowing green gram as a green manure on 3th July has significantly increased wheat grain yield compared with fallow treatments. In green manure applied plots, wheat grain yield in 60 kg N ha-1 and 45 kg P ha-1 was higher than 120 kg N ha-1 and 90 kg P ha-1 under fallow conditions. The higher grain per unit area and biological yield in green gram residue incorporated plots influenced higher wheat grain yield than under fallow.   Manuscript profile

      In order to investigate the comparison of urea and sulfur cotaed urea fertlizer on quantitative and qualitative yield of rice, Anbar Najafi cultivar under different silica, this research was conducted in Shadegan in 2017 carried out as split-plot based on randomized complete blocks design with three replications. Treatments consisted of urea fertilizer sources in two levels: simple urea fertilizer (250 kg net nitrogen) and sulfur coated urea fertilizer in main plots and silica at four levels: one in a thousand, two in thousand, three in thousand and four in thousand were in sub plots. The results showed that urea fertilizer and silica fertilizer significantly affected on grain yield, number of spikes per square meter, 1000 grain weight and protein content. Sulfur coated urea effectively yield compared to conventional urea fertilizer at a rate of 23.22 percent. Also, the interaction of urea and silica fertilizers on all measured traits was significant. The highest grain yield (290.41 g/m2) was obtained from urea fertilizer treatment with sulfur coating and spraying two in 1000 of silica. The highest protein content (10.04%) obtained in  sulfur coted urea fertilizer with two per thousand spray of silicon , respectively. Therefore, according to the results, values of two per thousand silica and urea fertilizer with sulfur coating due to increased protein and grain yield as a suitable treatment in the study area are introduced.

       The use of nanofertilizers and planting date might improve potato performance. In order to study nitrate accumulation and yield changes of potato tubers using different concentrations of iron (Fe) and magnesium (Mg) nano-particles in cultivation date of "Sante" cultivar, a split-split plot based on randomized complete blocks design with three replications were carried out in Research Farms of Jihad Keshavarzi located in Islamabad and Zeh-e Kalut region of Kerman province. Area as main factor and sub-factor including spraying of Fe and Mg nanoparticles (0, 1 and 2%) at flowering and tuber filling stages and sub-sub plot include two planting dates (5 and 25 October) were investigated.Results showed that mean tuber weight was significantly affected by different treatments of nano-particle spraying (p < 0.05).Effect of experimental treatments (area and date of planting) and their two and three effects was non-significant on tuber weight (p>0.05), but on yield were significant (p < 0.01). The highest yield was related to 2% spraying of Fe+Mg nano-particles on 5 October in Zeh-e Kalut area. Also, the highest tuber nitrate was obtained in control (spraying with distilled water) treatment. 1% Fe nano-particles and 1% Fe nanoparticle+2% Mg nanoparticle was divided into a single statistical group and showed significant difference with other treatments (p < 0.05).For all measured traits, it seems that the use of low consumption and essential elements through preservation of leaf greenness, improvement of photosynthetic system and increasing leaf durability led to increase length of tuber filling and tuber conversion and decrease in tuber nitrate.         Manuscript profile

      To investigate the effects of defoliation and nitrogen foliar application on yield physiology of sunflower, a experiments was performed in a randomized complete block design with split-plot arrangement in Gonabad region during 2015 and 2016 seasons. Nitrogen consists of two levels of spraying in flowering time (N1) and control (N2) in the main plots. Defoliation consists of five levels: Control (D1), 1/3 defoliation at 8th leaf stage (D2), 2/3 defoliation at 8th leaf stage (D3), 1/3 defoliation at beginning of the flowering (D4), 2/3 defoliation at beginning of the flowering (D5). In nitrogen deficiency conditions, by cutting 1/3 of the leaves at the first of the flowering, grain yield increased by 28% (0.54 to 0.75 kg ha-1) compared to control treatment .In the conditions of nitrogen consumption, after removing the 2/3 of the leaves at the first of the flowering, the amount of dry matter transfer reallocation from the stem to the grain showed a significant increase compared to the control, while in the conditions of non-nitrogen consumption, defoliation treatments had a slight effect on the contribution of stem reserves. Under the conditions of nitrogen deficiency, the negative effect of sink size restriction on grain yield is more than the negative effect of source strength restriction. constraints than the source power limitations On the practice Gain rejection is more. Plant breeders focus their programs to increase the efficiency of nitrogen consumption in order to increase the strength of the sink and reduce extra leaves with low efficiency in grain filling.

      In order to investigate the effect of using superabsorbent polymer on some growth parameters and performance of chickpea under drought stress conditions, a factorial experiment was carried out in the form of a randomized complete block design with four replications in the crop year of 2021 in Horand region of East Azarbaijan province. The experimental treatments include three levels of irrigation (full irrigation as a control, mild water restriction or irrigation interruption in the pod setting stage, and severe water restriction or irrigation interruption in the flowering stage) and different amounts of superabsorbent (no use of superabsorbent, 50, 100 and 150 kg/ha), respectively. The results of the analysis of variance of the studied traits showed that the application of stress and the effect of using superabsorbent polymer on all the evaluated traits were significant at the probability level of 1%. The interaction of drought stress and superabsorbent polymer on plant height, leaf chlorophyll content, number of pods per plant, grain yield and biological yield at the probability level of 1% and had no significant effect on other traits. so that the highest grain yield (1710.94 kg.ha-1) was given to the treatment (full irrigation and 150 kg.ha-1). The results showed that with increasing drought stress, the values of physiological traits such as chlorophyll content and relative water content of leaves decreased, but proline content of leaves increased. If the use of superabsorbent significantly increased the physiological traits. According to the obtained results, the superabsorbent reduced the damage caused by drought. Manuscript profile

          Available water is the main factor limiting crop growth and production in arid areas. In this regard, in order to investigate the effect of silicon application on morphological, physiological and yield characteristics of sunflower under different moisture levels, an experiment was conducted in the crop year 2018-2019 in Gonabad, Iran. This study was conducted as a split plot in a randomized complete block design with three replications. The main factor of irrigation with different moisture levels based on water requirement includes four levels (100% water requirement, 80% water requirement, 60% water requirement and 40% water requirement) and the secondary factor of silicon consumption time. There were four levels (no application (control), application in vegetative stage, application in reproductive stage, application in vegetative stage and reproductive stage). The results showed that reducing the moisture level from 100% to 40% of water requirement reduced the quantitative traits studied; So that the lowest seed yield (1730.8 kg / ha) and oil yield (583.41 kg / ha) were obtained in the treatment of moisture level of 40% of water requirement. Also, the application of silicon under low moisture levels based on water requirement improved the effects of reducing moisture levels in all evaluated traits and seed yield. The highest seed yield (7572.96 kg / ha) was obtained in the treatment of 80% water requirement and application of silicon in the vegetative and reproductive stages and the lowest value (1193.54 kg / ha) was obtained in the treatment of 40% water requirement and without the use of silicon. Also, the application of silicon in the vegetative and reproductive stages compared to the non-application treatment (control) increased 2.5, 1.5 and 2.5 times the oil yield at different levels of moisture, including 80, 60 and 40% of water requirement. In general, the results showed that the use of silicon in the vegetative and reproductive stages at a moisture level of 80% of the water requirement compensated for the adverse effects of reducing the moisture level in the studied traits.

      In order to investigate the effects of grain growth characteristic and yield components on grain yield of wheat cultivars, an experiment was carried out in randomized complete block design with three replications at Golestan province in 2008-2009. Experimental cultivars were Inia, Khazar 1, Golestan, Tajan, Atrak, Pastor, Darya, Zagros, Falat and Kohdasht. Pastor cultivar had maximum and Inia cultivar had minimum numbers of grain per spike. The highest seed yield belonged to Golestan, Falat, Atrak, Pastor and Darya and the lowest seed yield were seen in Inia cultivars. The highest and lowest grain harvest index was related to Falat Cultivar (46/8 percent) and Tajan cultivar (33/8percent) respectively. Filling grain period and grain number per spike had positive correlation with grain yield. Therefore, it seems that increasing sink strength by increasing the number of seed per spike and grain filling rate can lead to an increase in the yield of wheat cultivars.   Manuscript profile

      In order to study path analysis of grain yield with yield component in common bean genotypes and determine the traits that have most effective traitson grain yield, an experiment was conducted as a randomized complete block design with three replications in Research station of  agricultural and natural resources college of Tehran University in Karaj. Analysis of variance showed that there were significant differences among genotypes. Simple correlation coefficients between traits showed only the number of pods per plant and 100-grain weight had positive and significant correlation with grain yield. The results of stepwise regression analysis revealed that the most changing of grain yield concerned to the number of pod per plant, 100-grain weight and number of grain per pod. All intered traits to regression model studied by path analysis and this fact was found that the number of pods per plant and 100-grain weight had the highest positive direct effect on grain yield. Therefore, these traits can be used for the selection of high yield in breeding programs. Manuscript profile

      To investigate the effect of planting date on yield and some agronomic traits in local and high-yielding rice cultivars in direct cultivation by dry-bed seeding system was conducted in the form of a split-plot in a randomized complete block design with three replications. The main plot of planting date in three levels (June 15, June 25, and July 5) and four rice cultivars including two local cultivarsChampa and Red anbori and cultivars High-yielding and improved Danial and Shafagh was grown as a subplot at each planting date. Then, each plot was divided into two parts. The upper part of plot was not weeding and was considered as a control and the lower part of the plot was removed by hand weeding. Based on the results, the effect of planting date and cultivar on biological yield, grain yield, and the number of spikes per square meter under weed control conditions was significant at the level of one percent. In this experiment, the highest yield was observed on the date of the first planting in the high-yielding cultivar Shafagh and at the rate of 5253 kg/ha. The results showed that grain yield loss due to weed presence was different depending on planting date, so that the highest and lowest production loss with the average of 1815 and 1090 kg/ha was related to the first and third planting date, respectively. Among rice cultivars, a decrease in grain yield of 40.85 and 32.95 percent was observed in high-yielding cultivars and local cultivars, respectively. Manuscript profile

      Drought is one of the most important nonliving stresses affecting the growth of plants, thereby limiting the agricultural yield of the plant. Measures including presenting information for improving the drought risk management, improving planning for more effective reaction to drought, investment on disaster risk reduction (DRR), and presenting an environment for minimizing the general risks lead to enhanced endurance, as well as prevention or reduction of future drought risks along with maintaining livelihoods. This research was performed in two agricultural years as split court experiments in the form of fully randomized block with four replications. Various conditions of soil humidity were considered as the main treatment at three along with the treatment of biofertilizers at seven levels, considered as secondary treatments. The study results indicated that various humidity conditions of the leaf relative water content (RWC), the greenness index of leaves (SPAD), chlorophyll a and b, as well as the grain yield became significant. With increase in the severity of stress, their values decreased suggesting their sensitivity to changes in the status of soil water and the leaf water potential. Usage of azotobacter and Phosphobacteria biofertilizers resulted in significant elevation of SPAD, RWC, chlorophyll a and b, as well as grain yield compared to the nonuse of biofertilizers. The effects of combined use of microorganisms led to compensation of the water stress damages. Generally, considering water deficit conditions and temperature elevation resulting from climate change, use of microorganisms as seed priming can considerably reduce these risks. Manuscript profile

      In order to evaluate the efficacy of 2,4-D and tribenuronemethyl herbicides on ecotypes of hoary cress (Cardaria draba L. Desv) and the possibility of reducing the recommended dose, the dose-response experiment was performed as a randomized complete block with three replications in Ghaem Park greenhouse, Tehran in 2020. The studied ecotypes were Salmas, Rafsanjan, Semirom, Shahrekord, Baft, Birjand, Semnan and Karaj and the two herbicides were used in four doses (25, 50, 75 and 100% of the recommended dose) in the 4 to 6 leaf stage. The results showed that 2,4-D was more effective in controlling hoary cress ecotypes than tribrenuronethyl. By applying 100% of the recommended dose of 2,4-D, the dry weight of hoary cress ecotypes decreased by 91-99%. The dose of ED50 in response to 2,4-D and tribenuronemethyl for hoary cress ecotypes ranged from 0.41 to 0.89 lit hec-1 and from 8.5 to 17.27 g hec-1, respectively. Based on the estimated ED50 dose, the most sensitive and resistant ecotypes of hoary cress to both herbicides were Semirom and Karaj, respectively. Due to the 90% reduction in dry weight of Semirom, Baft, Shahrekord and Rafsanjan in 75% of the recommended dose of 2,4-D, the dose required to control these ecotypes can be reduced and less herbicide used.

      Weeds are one of the most important factors threatening agricultural products with high yield and quality. Ethalfluraline is a selective herbicide from the dinitroaniline group and is available in the market under the Sonalan brand. The main purpose of allelopathic research is to provide evidence for the interference of chemicals under natural conditions and the introduction of alchemicals that inhibit other plants and microorganisms in the natural or agricultural ecosystem. This experiment was performed to investigate the allelopathic effect of rapeseed and Sonalan herbicide on germination and some characteristics of cotton using a factorial design in a randomized complete block design with four replications. The treatments used include the amount of canola residues (soil without residues, 5% residues, 10% residues, 15% residues and the amount of Sonalan herbicide without herbicide application, 1.5-2 liters per hectare, 2-3 liters per hectare. In general, it showed that Sonalan herbicide in the amounts used for cotton fields did not have a significant effect on the germination of yield components and related traits in cotton plants and decreased by 12%. However, the height of the crop plant, the number of nodes on the stem and the number of leaves of the crop plant were not affected by the amount of residues. Dry weight of cotton 90 days after planting was significantly affected by residue level. Manuscript profile

      This study aims to identify relationships as well as the positive and negative influence of the related traits to the sugar of organs and different periods of growth, ion, biochemistry, enzyme and hormone as the independent variable with the grain yield as the dependent variable. Twelve genotypes were carried out in the random complete blocks’ design with three replications that were consistent with the climate conditions of Khuzestan. They can impact significantly on the grain yield changes in the sugar of the vegetative, reproductive organs at the stage of physiological maturity of the flag leaf and root, in the pollination stage, in the nitrogen ions, in the biochemical traits of the Malondialdehyde, protein, starch and proline attributes and between the abscisic acid enzyme and hormone, Catalase and Guaiacol. The sugar in the flag leaf had the highest percentage of significant change in the level of 1% with the yield grain at the physiological maturity stage, nitrogen, Malondialdehyde (MDA) and abscisic acid, with negative, positive, negative and negative relation, respectively. The obtained results can be the major and important target for genetic modification of the rice varieties to increase the grain yield of the plant as an economic and strategic product.

      In order to study the effect of harvesting time on germination characteristics and some antioxidant properties of different wheat varieties, this study was carried out in a factorial in a completely randomized design with three replications in Izeh city. The experiment factors consisted of harvesting time at two levels of harvesting in hard-paste and harvesting stage at maturity stage and bread and durum wheat cultivars in six levels of Natasha, Aflak, Chamran, Dehdasht, Behrang and Karkheh. The results showed that the highest antioxidant content of the seeds, such as polyphenol, flavonoids and antioxidant capacity, belonged to Chamran cultivar and harvest at maturity stage. The least of these cultivars was Aflak and Karkheh cultivars in the stage of hardening. Also, harvest time significantly affected germination percentage and seedling length of different wheat cultivars. The percentage of germination with accelerated grain harvest decreased significantly. In interaction, harvest time and cultivar had the highest percentage of seed germination (99%) to Chamran and Dehdasht cultivars and harvest at seedling stage. Reducing the percentage of germination and consequently reducing seedling length with accelerated seed harvesting in the dough step of hardening of the seeds resulted in reduced seed yield. In general, maximum germination and antioxidant content was obtained from harvesting stage at maturity stage. Chamran cultivar compared to other cultivars showed significant superiority in terms of traits. Manuscript profile

      The study is designed with the aim of studying the effect of different levels of selenium fertilizer and cow manure on the concentration of selenium in alfalfa. For this purpose, a pot experiment with complete randomized design in the form of a factorial experiment was carried out with five levels of selenium fertilizer (0, 5, 10, 20 and 40 g ha-1), and two levels of cow manure (Zero and 100 tons per hectare) with three replications in the greenhouse, using Lavark soil of research farm of Isfahan University of Technology in 2016. The selenium content of the samples was measured using atomic absorption device. The results of the experiment showed that the effect of selenium fertilizer levels on selenium concentration in the plant was significant in all three harvestings, but selenium concentration showed consecutive decreases in the consecutive impressions. Increasing the application of cow manure significantly increased alfalfa yield in all three harvests, and the average harvest yield was more than the second harvest, and it was more than the first harvest. The use of animal manure reduced the concentration of selenium in plants and decreased in successive consecutive. In general, selenium fertilizer without the presence of animal manure increased the concentration of selenium in the studied plant. Manuscript profile

      In order to investigate the effect of different levels of tillage and residues on the yield and yield components of wheat (cv. Mehregan), a research was conducted in 2015 cropping season in south west of Iran. The study was consisted of a strip-plot experiment, using Randomized Complete Block Design (RCBD) with three replications. The investigated treatments included tillage in three levels (including conventional tillage, protective tillage and no tillage) as horizontal plots and plant residues in three levels (including zero, 30 and 60% wheat residues) as vertical plots. The results showed that the tillage treatment had significant effect on yield and yield components, harvest index, percentage and yield of protein. The highest grain yield (with an average of 477.5g.m-2) was obtained from the conservation tillage treatment and the lowest (with an average of 340.3g.m-2) from the no-tillage treatment. Also, the application of plant residues significantly affected yield and yield components, biological yield, harvest index, percentage and yield of protein. The highest grain yield (with an average of 480.7g.m-2) was obtained in the conservation tillage method with the application of 30% residues on the soil surface. Based on the results and considering the positive effects of conservation tillage method, it was suggested to use 30% of residues in this tillage method in Izeh region in order to increase wheat yield.

      In the present study, the influence of foliar application of salicylic acid and biofertilizers on modulating the effects of drought stress on some morphophysiological characteristics, dry matter yield and essential oil production of basil (Ocimum basilicum L.) was investigated using a factorial experiment based on a randomized complete block design in triplicate within the 2019 in Hurand . Experimental treatments included three levels of drought stress (70, 140 and 210 mm of evaporation from Class A evaporation pan) as the first factor, seed inoculation with bacteria at five levels (no inoculation as control, inoculation with Azotobacter, Pseudomonas, Azospirillum and co-inoculation with Azotobacter, Pseudomonas and Azospirillum) as the second factor and salicylic acid foliar application at four levels (0, 0.5, 1 and 1.5 mM) as the third factor. .The results of this study showed that the drought stress had an important role in reducing the basic factors in basil growth. The results showed that with increasing the intensity of drought stress, the proline content increased. So that the highest proline content (1.69 μM/g fresh weight) were obtained from the treatment of 210-mm evaporation. Based on the results obtained in this experiment can be expressed, the use of salicylic acid at a concentration of 1.5 mM and the co-inoculation of bacteria play a role in relieving the negative effects of drought stress and their administration can effectively increase the quantitative and qualitative properties of the basil.

      In order to evaluation of trend yield and physiological indices variation of some current Rice cultivars an experiment was carried out in split-plot arrangement using randomized complete blocks design with three replication. In 2006 and 2007 years at Shavoor Agricultural Research Station in Khuzestan province. For exposing rice cultivars to different higher temperature regimes, main plots were assigned to three sowing dates from 5 May with 20 days intervals and cultivars namely: Hoveizeh, Hamar (heat tolerance) Ghermez Anbori, Champa (heat sensitive) and Danial (relatively heat tolerant) were randomized in sub-plots. The results of combined analysis of variance showed that the highest grain yield was harvested from the second sowing date (26 May). It was the superior to first sowing date (5May) with 62.5 percentages. The reason of higher yield related to superior physiological indices in panicle exertion, LAD in ripening duration and also higher dry matter storage potential. In among cultivars, Hoveizeh was the superior to other cultivars and had higher yield related to Ghermez Anbori, Champa with 50.9 and 36.3 percentage respectively. In spite of heat sensitive cultivars had higher of Maximum leaf area index but their's crop growth rate, net assimilation rate and relative growth rate were lower. Manuscript profile

      In this research, we try to predict the yield of rainfed barley in Khorasan provinces using climatic parameters and two methods of artificial nervous netwework (Ann) and fuzzy neural system (Anfis). Calculations were performed with MATLAB software and then the statistical indices of correlation coefficient (R2), root mean square error (RMSE) and full mean error (MAE) were used to evaluate the performance of the models. Last year's yield and rainfall had an effective role in reducing prediction error and increasing correlation coefficient in both Ann and Anfis methods. Last year's yield and evapotranspiration made the Anfis method more accurate than the Ann method. The results of both Anfis and Ann methods for model L inputs, which included rainfall, relative humidity and last year's yield, showed that this model achieved the highest accuracy among the input models. However, in the Anfis method for model E inputs, which included evapotranspiration, rainfall, relative humidity and minimum temperature, the results showed that it was more accurate than the Ann method. The greatest difference in accuracy in estimating yield between the two Anfis and Ann methods was observed with R inputs model, which includes moisture inputs, Dew point temperatures and maximum temperatures. The presence of radiation parameters at the inputs reduced the accuracy of yield estimation in both methods. Overall, the Anfis method was more accurate in estimating yield than Ann.

      Prediction of weed emergence timing would help reduce herbicide use through the optimization of the timing of weed control. In order to predict the emergence of wild buckwheat (Polygonum convolyulus L.), alkafaun (Fumaria vaillantii Lois) and Field bindweed (Convolvulus arvensis L.) by using the temperature model, an experiment was conducted at wheat field research of university of Tehran, Karaj during 2012-13. Based on the results, 50 percent of cumulative emergence of wild buckwheat were obtained in 75.21, 71.48 and 75.21 growing degree day at inner margin, center and outer margin of wheat field, respectively. The presence of wheat was not impressed the emergence of wild buckwheat. It was for that this weed was not required light for germination. Alkafaun emergence was happened at higher growing degree day at inner margin of field. Of course alkafaun had lower emergence per received GDD at outer margin in comparison with other parts of the field. Although emergence had lower slope per growing degree day at this part, but it was achieved to 50 percent cumulative emergence with lower received GDD. It was this time that 50 percent cumulative emergence of alkafaun achieved with 49.11 and 45.90 GDD at center and outer margin of field, respectively. Field bindweed was achieved to 50 percent of cumulative emergence with 158.98 and 150.60 growing degree day at inner margin and center of field. but there was no direct correlation between the number of weeds in the wild buckwheat seed bank and the number of seedlings were emerged.

      The irrigation with a magnetic water increases the yield of plants by improving solubility and the nutrient availability in the soil profile. Furthermore, methanol spraying as a source of carbon dioxide, which increases the concentration of this gas around the plant, enhances the photosynthesis and plant yield. This study was conducted to evaluate soybean reaction by irrigation with different magnetic field intensities and foliar application of different concentrations of methanol in the research field at the Agriculture Faculty, Islamic Azad University-Sanandaj branch, during two consecutive years (2017–2018). The experiment was designed as a split plot in a randomized complete block design with 3 replications. Different intensities of magnetic water (0, 4, 8, 12 mTesla) were used in the main plot and foliar application of methanol concentrations (distilled water: control, 10, 20 and 30% v/v) in sub-plots. The results showed that the height of first axillary stem decreased significantly, but grain yield, biomass, oil and protein yield were significantly higher in treatments with magnetic water. Grain yield, increased by magnetic irrigation with 4, 8 and 12 mT intensities, compared to the control, by 45.56, 70.05 and 72.19%, respectively. Also the all characters were significantly affected by methanol spraying× year interactions. The interactions of magnetic water × methanol foliar applications were significant in some characters. However, based on interaction effect, the superiority of the studied traits was evident in the second year under the influence of magnetic water at 8 mT and 20% methanol. Manuscript profile

      Weeds Malva neglecta, Echinochloa crus-galli and Sorghum halepense are weaned and weedy species in wheat, cane, rice, corn, sifiyat and gardens of northern Khuzestan. In order to determine the effects of salinity stress and moisture stress in conditions of burnout and exhaustion on germination ability of seeds and emergence of these weeds, a test was conducted in a Seed Technology Laboratory of Shushtar Islamic Azad University in a completely randomized factorial design with four replications Took In the first laboratory conditions, the first factor was seeds of weeds of canola, spruce and grass, and the second factor was burning treatments including: control (without burnout) and burnout days (three, five and seven days) and the third factor of salinity treatments (four, eight and 12 ds) Siemens / m and a salinity of 0.7 dS / m). The results of analysis of variance showed that among all studied traits (germination percentage, germination rate, germination uniformity index, seedling dry weight, Vigor index), there was a significant difference at probability level there was a percentage. Weed seeds of Malva neglecta were more successful in germination traits than other two weeds, and Echinochloa crus-galli weed seeds also had better reaction to burnout in the depositional traits. Weed seeds of Sorghum halepense showed the highest sensitivity to the other two weeds compared to the accelerated aging test. Therefore, burnout and salinity stress reduced all studied traits in these weeds. In general, it can be concluded that the burnout of seeds under conditions of salinity stress reduces the germination characteristics and weed deployment of weeds tested. Manuscript profile

      This research was conducted with aim of investigating the effects of organic and chemical fertilizers along with silicon on morpho-physiological characteristics and yield of purple coneflower (Echinacea purpurea L.), in Mazandaran,, Amol during 2022. The experiment was cconducted as a split-plot in a randomized complete block design with three replications. The experimental treatments include the application of organic and chemical fertilizers at four levels (control, manure, vermicompost and chemical fertilizer) as the main plot and silicon at three levels (control, potassium silicate and nano-Si) were considered as sub plot. The results indicated that the most growth characteristics like plant height, number of flowers per plant and leaf area were obtained by chemical fertilizer. The highest dry weight of plant organ was achieved with use of chemical fertilizers. The highest dry weight of flowers (429.3 g.m-2) was obtained by chemical fertilizer, which was not significantly different from the use of vermicompost (417.3 g.m-2). The application of both sources of silicon led to improvement in the number of flowers per plant, leaf area, and concentration of chlorophylls compared with control, although the application of nano-Si had higher improvement effects compared with potassium silicate. The nano-Si increased the dry weight of flowers by 9.6 and 7.4% compared with non-application of silicon and potassium silicate, respectively. Therefore, according to the findings of the present study, application of vermicompost organic fertilizer is introduced as a suitable alternative to chemical fertilizers, as well as nano-Si application to improve the morpho-physiological characteristics and yield of purple coneflower.

      Drought stress is one of the main reasons for the reduction of quantitative and qualitative yield in sugar beet cultivation, on the other hand, the increasing reduction in available water, especially in arid and semi-arid regions, has made the worse situation. In this situation, the use of drought-resistant cultivars is an effective way to reduce production risk. For this purpose, experiments were conducted in the form of split plots in based of RCBD statistical design with the main factor of irrigation (90 and 180 mm) and sub-genotype factor (16 hybrids and 4 genotype control varieties) in the years 2016 and 2017 at Karaj Sugar Beet Research Institute. The results showed that there is a decreasing trend in the average root yield and white sugar yield in two years under stress conditions of 28.5 and 10.5%, respectively, compared to normal irrigation conditions. However, under stress conditions, sugar content had an increasing trend, and root impurity values (sodium and nitrogen) had a decreasing trend, which was accompanied by the highest values of the sugar extraction coefficient. Also, the reduction of water consumption in stressful conditions led to an increase in the efficiency of irrigation water in stressful conditions compared to normal. In the examination of genotypes, based on two indices of tolerance and resistance to drought stress and yield index, genotypes number 1, 3, 9, 12, and 16 were identified as promising genotypes.

      This experiment was conducted as factorial based on completely randomized blocks design with 3 replications during 2014-2015 in Ramhormoz, Khozestan province. The experiment consisted of two factors: nitrogen fertilizer rates: (zero, 50, 100 and 200 kg per hectare) and split nitrogen application included: T1 = (50% at planting + 50% at stem elongation), T2 = (33% at planting + 33% at stem elongation + 33% before ear emergence), T3 = (25% at planting + 50% + 25%at stem elongation before ear emergence) and T4 = (25% at planting + 25% + 25% at stem elongation before ear emergence + 25% in the milky stage. The results showed that difference between the levels of nitrogen fertilizer in plant height, number of spikes per square meter, grain number per spike, 1000-seed weight, grain yield, biological yield, harvest index and the amount and efficiency of current photosynthesis at 1% level of probability and remobilization rate of dry matter at 5% level of probability. Effect of split application of nitrogen on plant height, number of spikes per square meter, grain yield, biological yield and current photosynthesis at 1% level of probability and the efficiency photosynthesis current at 5% level of probability was significant. The interaction of the amount and nitrogen fertilizer splitting on biological yield and efficiency of dry matter remobilization and efficiency of current photosynthesis at 1% level of probability was significant. The highest grain yield was in N2 (100 kg ha nitrogen) with 5.5141 kg/ha and fertilizer splitting in T3 (25% at planting + 50% + 25% at stem elongation before ear emergence) 4.4592 kg/ha, respectively. The greatest amount and efficiency of current photosynthesis were observed in N2 (100 kg/ha nitrogen) and T3 (25% planting + 50% + 25% stem elongation before Ear emergence). In general, consuming 100 kg/ha of nitrogen fertilizer with T3 splitting (25% planting + 50% stem elongation + 25% before Ear emergence) increase yield and yield components compared to other treatments and it can be recommended in the region of study.

      Salinity stress is one of the important stresses affecting germination, growth, production and quality characteristics of wheat. Researchers have described salt stress as the accumulation of ions such as sodium, sulfate, and chlorine in the rhizosphere environment in a way that disrupts the natural growth of plants. Salinity stress through reducing the cell pressure, inhibition the functioning of membranes, affecting the activity of enzymes, inhibiting photosynthesis and inducing ion deficiency due to the reduction of ion transport and other physiological processes causes a decrease in growth, leaf area index, biomass and grain yield. Wheat cultivars show different reactions to soil and water salinity. Increasing tolerance to salinity in bread wheat cultivars is related to a decrease in sodium concentration in the plant and also a decrease in the sodium to potassium ratio in the leaves. Separation of sodium in leaves and preferably potassium is related to the presence of D genome in hexaploid wheats. In general, investigating physiological reactions, especially in salinity tolerant genotypes, is helpful for plant breeders to release salinity tolerant genotypes. This research is to study the effect of salinity stress on some characteristics Physiological and growth of wheat has been discussed. Manuscript profile

      In order to investigate drought tolerance of maize hybrids, a split plot experiment was conducted in a randomized complete block design (RCBD) with three replications in the research field of Payame Noor University (PNU) of Kermanshah in 2013. The main factor included drought stress (stress and normal condition) and sub factor including nine corn hybrids. The results of analysis of variance indicate the different reaction of the hybrids studied for grain yield and the ability to select hybrids based on yield. Comparison of numerical values ​​and rank of each hybrid based on grain yield based on grain tolerance index showed that hybrids number one, three, seven and eight were identified as drought tolerant hybrids.Results of correlation analysis showed that MP, GMP, STI, HAR, K1, K2, SSPI and YI had positive and significant correlations with Yp and Ys.They are suitable for choosing high yield hybrids in both conditions. Gabriel's bi-plot drawing was performed based on the analysis of the main components. Based on this breakdown, the first two components justify about 98 percent of the variance. The results showed that the studied hybrids were located in two groups of high yield potential and weak potential, so that hybrids number one, three, seven and eight were placed in the vicinity of drought stress tolerance vectors as superior hybrids. The cluster analysis, based on the superior indices of the studied hybrids grouped the hybrids into two clusters that are similar to the Gabriel bi-plot. Manuscript profile

The main plots were consisting of four levels of chemical fertilizer (100, 50 and 25% of recommended NPK and no chemical fertilizer application (use of farmyard manure), and sub plots were consisting of three levels (no-inoculation; inoculation of seeds with biofertilizers containing growth-promoting bacteria and phosphate and potassium Solubilizing Bacteria (Azeto Barvar+Phosphate Barvar+Peta Barvar); seed inoculation with biofertilizers containing bacteria+Aspergillus fungus). The highest grain yield belonged to the 100% NPK, but between the two levels of 100 and 50% NPK consumption in terms of plant leaf number, ear length, ear diameter, number of rows per ear, number of grains per row and 1000-grain weight there was no significance difference. Grain yield and yield components were affected by biofertilizer application and there was no significant difference between the two levels of seed inoculation with biofertilizers containing bacteria and seed inoculation with biofertilizers containing bacteria+Aspergillus. In case of non-inoculation of seeds, with 50% reduction of NPK consumption, grain yield decreased by about 24%. However, by inoculation of seeds with biofertilizers containing bacteria and 50% reduction of NPK consumption, grain yield compared to 100% NPK consumption without inoculation Seeds was decreased about 12%. Therefore, co-inoculation of seeds with Azeto Barvar, Phosphate Barvar and Peta Barvar biofertilizers in combination with 50% of the recommended consumption of NPK chemical fertilizer is considered suitable for corn cultivation in Ramhormoz region due to reducing the cost of chemical inputs and preventing environmental pollution Manuscript profile

      In order to investigate the effect of growth promoting bacteria and potassium sulfate fertilizer on quantitative and qualitative characteristics of corn an experiment based on randomized complete block design with three replications was conducted in summer 2015 in Shavour Agricultural Research Station, affiliated to the Agricultural and Natural Resources Research Center of Khuzestan. The treatments included: T1: Without inoculation and use of potassium fertilizer at recommended rate (as control), T2: using autoclaved inoculum and using chemical fertilizer of potassium as recommended, T3: inoculation with biological fertilizer of Pseudomonas and application of potassium fertilizer to Recommended rate, T4: Inoculation with biological fertilizer of Pseudomonas without the use of potassium fertilizer and T5: Inoculation with biological fertilizer of Pseudomonas and Potassium fertilizer use were 50% less than recommended rate.  The results showed that the effect of treatments on the number of rows per ear, number of seeds per row, 1000 grain weight, grain yield, biological yield, starch percentage and potassium percentage of seed and in regard to phosphorus percentage was  not significant. The maximum grain yield and biological yield was belonged to T3 treatment. T4 treatment showed the minimum grain yield and biological yield. There was no significant difference between two treatments of T3 and T5 in terms of starch percentage. The highest amount of potassium was obtained from T3 treatment and showed the lowest amount of T4 treatment. In general, there was no significant difference between T3 and T5 treatments in terms of quantitative and qualitative characteristics of yield and the T5 treatment was recommended as a suitable treatment due to reduced potassium fertilizer in terms of sustainable agriculture and reduction of environmental pollution.

      Since the yield of sugar beet is affected by the length of the growing period and agronomic management, to investigate the delayed cultivation, this experiment was conducted in 2015 and 2016 with two treatments of planting row spacing (Pr) with two levels of 25 and 40 cm (main plot) and three levels of plant spacing on row (Ps) using 1.7, 2.4, and 3.1 units per hectare seeds (sub-plot), it was carried out in the form of split plots with a RCBD in four replications. By adding the harvest date treatment with two levels of conventional and delayed in the second year, the statistical design was changed to split plots factorial (Ps and harvest date as factorial). The highest percentage of white sugar content (WSC) and potassium was obtained in the 40 cm row spacing. In the second year, a 37% decrease in the number of final roots compared to the first year caused a 25% decrease in root yield (RY), 31% in white sugar yield (WSY), and 21% in irrigation water use efficiency (IWUE). Contrary to the first year, the effect of Ps was not significant on traits such as RY, WSY, and IWUE, while it had no significant effect on the percentage of WSC in any of the two years. In the second year, with a delay in harvesting, the increase in WSY and IWUE was 32% and 16%, respectively. Therefore, Pr of 25 cm and Ps of 22 cm (2.4 units) is recommended for the Karaj region.

      In order to study effect of seedling age and plant density on yield and yield components of rice (Sadri cultivar), a field experiment was conducted at the Ordukhan Agricultural Research Center, Heart Province - Afghanistan (Geographical longitude: 62°11'29" east and geographical latitude: 34°20'35" north) during the cropping season 2017-2018. The experiment was laid out in complete block design with three replications. Seeding ages with three levels (20, 30 and 40 days) were considered as main plots and plant densities with four levels (13, 17, 22 and 33 plants/m2) were allocated as sub plots. Analysis of variance showed that the effect of seedling age on number of tillers per plant, numbers of grains per panicle and grain yield was significant. The plant density had significant effect on all traits (expect, 1000grains weight). Interaction of two factors had no significant effect on any of the traits. The means comparison showed that the highest of number grains per panicle and grain yield were obtained for 30 days seedling age. Also, the highest of number of tiller per plant, number of fertile tiller per plant, number of grains per panicle and percent of unfilled grain were obtained by 13 plants per m2. But the highest biological yield, harvest index (HI) and grain yield obtained by 33 plants per m2. Based on simple correlation coefficient of traits, grain yield had significant positive correlation with biological yield, number fertile tiller per plant and number grains per panicle.

      This study aims to prepare a paternal parent (pollinator) tolerant to drought stress using full sib families in the Karaj region in Motahhari's station of Sugar Beet Research Institute in 2015 in conditions without stress (based on water needs) and drought stress. For this purpose, an experiment in the form of a split-plot design was conducted with 13 full sib families, two drought-tolerant cultivars (IR7) and (stable), and a normal genotype (191) as control cultivars, with the main factor consisting of two levels (irrigation with drought stress and irrigation without stress) and the sub-factor of all sister families and control genotypes implemented in four replications for one year. After emergence, irrigation treatments were used in both instances (at least twice irrigation). At a probability threshold of 1% and 5%, respectively, the results revealed a statistically significant difference between irrigation treatments for root production and gross sugar output. As a result, a stable cultivar has the largest production of these two qualities.Furthemore, in the two modes of regular watering and stress, the mean root output in the examined families revealed a significant difference at the one percent probability level. Drought stress (SI = 0.72) lowered root and sugar yields. Cultivar 3, origin S1-930637, also has the greatest percentage of gross sugar and the highest drought tolerance index. Manuscript profile

      In order to determine the most suitable cultivars and barley lines in different planting dates, an experiment was conducted during 2019-2020 in Ghizanieh region of Ahvaz. The main factor includes three planting dates (1 November, 16 November and 1 December) and the sub-factor also includes six cultivars and lines of barley (Auxin, Nowruz, Nimroz, WB-95-3, WB-95-9 and WB-95-19) was done using split plots in a randomized complete blocks design with three replications. The measured traits were stem length, spike length, grain length, number of hollow seeds, number of seeds per spike, 1000-seed weight, number of spikes per square meter, grain yield, biological yield, harvest index, grain nitrogen percentage, grain protein percentage and plant growth indices. Results showed that the effect of sowing date on grain yield, number of seeds per spike and number of hollow seeds was significant at 5 درصد probability level. Planting date of 1 November reduced seed yield and increased number of hollow seeds and the third planting date also reduced number of seeds per spike and grain yield. Nowruz cultivar had more spikes per square meter in early planting date than late planting date. At the date of early sowing of barley, the highest number of hollow seeds was produced per spike. In late planting, plant height decreased and as a result, the biological yield also decreased. Planting date of 16 Nov. had the highest number of seeds per spike.  The highest yield obtained in Auxin cultivar with an average of 7710 kg.ha-1 on the second  planting date and line WB-95-19 at the same planting date with an average of 7226 kg.ha-1. 16 Nov. planting date, which had the highest seed yield, had the highest LAI and NAR. Seed nitrogen had the highest level in early sowing date in WB-95-3 line and decreased in late sowing dates. In general, the results of this experiment showed that early sowing of barley, reduced grain yield and sowing of Auxin cultivar on November 16 in Ghizaniyeh region had the best economic yield.  Manuscript profile

      Water deficit is a common and major constrain for agricultural production in arid and semi-arid parts of the world like Iran, to the extent that it might threaten the nation’s food security in years to come. Seed germination is a crucial growth stage that is often affected by environmental stresses, including drought. This study investigated the effects of four levels of water osmotic potential (i.e. 0, -3, -6 and -9 bar) on germination and seedling characteristics, of three maize hybrids )SC500, SC640 and SC704). According to the results, different levels of drought stress, type of cultivar and intraction beatween them had significant effect on measured characteristics. Results also showed that significant decrease was observed in the percentage and rate of germination, radicule and plumule of long and weight and seedling total dry matter. SC500 as a drought-tolerant hybrid, indicated the greatest germination percentage radicle and plumule length, radicle and plumule dry weight than the other cultivars. So, this hybrid was more tolerance to water stress. Manuscript profile

      In order to investigate the effect of different amounts of chemical fertilizers (urea) and organic (sugar cane filter) on wheat yield, an experiment was conducted in 2014 as split plots in a randomized complete blocks design with three replications in the land cultivation plant of Haft Tape sugar cane (Shush) was implemented. Sugar cane filter fertilizer was used in four levels (without filter cake (T1), 20 t / ha (T2), 40 t / ha (T3) and 60 t / ha (T4) as the main factor and Fertilizer urea was considered as a sub factor in there levels of fertilizer: No-fertilizer (N1), 100 kg/ha (N2) and 200 kg / ha (N3). The results of analysis of variance of treatments showed that the effect of sugar cane filter at 5% probability level and fertilizer urea at 1% probability level was significant for all studied traits except for 1000 seed weight. Also, interaction of treatments on yield and yield components of wheat was not significant. The results of the comparison of the mean of the data showed that the increase of sugar cane filter as a organic matter to soil, plant height, spike length, spikelet number per spike, number of seeds per spike, number of spikes per square meter, 1000 grain weight, grain yield per square meter and harvest index significantly increased. The treatment of 60 tons of filter cake per hectare increased seed yield by about 137. 6 gr/m2 (from 648.4 to 510.5 gr/m2), equivalent to 21.2% of the control (without filter cake). Using Urea fertilizer, the measured traits significantly increased compared to the control. The application of urea fertilizer at 200 and 100 kg/ha increased grain yields of 228.5 and 201.3 gr/m², equaling 33.6% and 32.6%, respectively. In general, the results showed that increasing the use of urea and organic fertilizers has led to a significant increase in growth and functional attributes, and the best treatment for chemical fertilizers and organic fertilizers is 200 kg/ha and 60 T/ha of filter cake, respectively.

      This research was performed as a factorial in a completely randomized design in a pot with four replications. The studied treatments include salinity of irrigation water as irrigation with ordinary water (0.4) (control) and with salinity of 4 and 8 dS/m and seed priming including no priming and seed priming in 25 and 50 mM of hydrogen peroxide solutions. In this experiment, the number of spikes per pot, number of spikelets per spike, number of seeds per spikelet, 1000-grain weight, root dry weight, grain yield and grain protein were investigated. In this study, the effect of salinity of irrigation and hydrogen peroxide on all studied traits were significant. The interaction effect of salinity of irrigation and hydrogen peroxide on the studied traits except grain number per spikelet and grain protein were significant. The maximum root dry matter (0.95 g/pot) and grain yield (7.49 g/pot) were observed under irrigation with normal water and application of 50 mM hydrogen peroxide and the minimum root dry matter (0.82 g/pot) and grain yield (3.17 g/pot) was obtained at salinity of 8 dS/m and non-application of hydrogen peroxide. The maximum grain protein (14.25%) was obtained in the application of 50 mM hydrogen peroxide and the minimum protein percentage (11.05%) was obtained under irrigation with normal water. In general, the application of hydrogen peroxide can be effective in increasing the quantitative and qualitative yield of wheat and reducing the effect of salinity of irrigation water and it can be considered and recommended by researchers and farmers.

      The use of polyamines with an impact on a wide range of plant growth and developmental processes can in/directly influence the growth indices and metabolic performance of the plant. This experiment was performed in a randomized block design with 10 treatments including spermine, spermidine and putricin each at three levels of 50, 100 and 150 mg / l with 3 replications. Non-foliar treatment was utilized as a control treatment. The results demonstrated that foliar application with different levels of polyamines had a significant impact (P≤0.01) on traits such as root dry weight, wet and dry weight of shoots and also a significant effect (P≤0.01) on traits such as chlorophyll, a, b and total chlorophyll, height, side branch, the number of umbela and weight of 100-seeds. The highest dry weight of roots, wet and dry weight of shoots and the numbers of side branch were related to spermidine treatment 150 mg/ l, the highest chlorophyll a and b and total chlorophyll and the number of umbels related to spermine treatment 150 mg / l, the highest carotenoids related to spermine treatment 100 mg / l and The maximum weight of 100 seeds and height for putrescine treatment was 150 and 100 mg / l respectively. Based on the results of this study, it seems that spermine and spermidine have been effective on more traits. Foliar application of polyamines can also increase the quantitative and qualitative yield of the plant and change the majority of traits. Manuscript profile

      This study was aimed to evaluate the effect of planting method on the morphological and anatomical properties of Iranian alliums native populations. The experiment was conducted in spilt plot base on randomized complete block design with three repetitions for one year in Khuzestan. Main factor was at two levels (1: stream and ridges and 2: plot) and the secondary factor included two alliums masses of Shadegan and Ahwaz19. Results showed that on-ridges planting, in terms of better input management, in spite of having the minimum number of plant per square meter, had the higher level of agriculture properties such as more leaf per plant, length, width, and weight. Maximum stomata diameter and surface was achieved from plot planting, which increased the resulted-from–the yield quality reduction transpiration and dehydration in this method of planting, while the maximum number of stomates, because of the optimal conditions, was gained through the on- stream and ridge planting in Ahwaz19, and can be the main reason of the increase of the leaf’s dry weight. Based on these results, it seems that by concentrating the modifying goals on the mentioned anatomical properties, with the appropriate method of planting, we can hopefully expect an increase in yield resulted from the increase of pure photosynthesis.

      A test was conducted in Achachi village by a split-plot factorial design in form of a completely randomized design model with three replications in 2017-2018. The treatments include three stress levels (a1: without stress (flooding), a2: irrigation interval per 10 days (from the beginning of clawing step), a3: irrigation interval of 20 days (since the clawing step), zeolite in two levels (b1: non-use (control), b2: 10 ton/ha), and cultivars in 4 levels (c1: Shahpasand, c2: local Tarom, c3: CT13382-8-3-M, c4: Sangjoo). The maximum yield was in a combination of flooding and zeolite use in cultivar of CT13382-8-3-M with an average of 5.9 ton/ha, and the minimum yield was in a combination of once every 20 days’ irrigation and non-use of zeolite in a cultivar of Shahpasand with the average of 1.06 ton/ha. The maximum transfer of the dry matter from the aerial parts was obtained when Sangjoo cultivar was irrigated once every 10 days in non-use of zeolite (816 kg/ha), and the share of grain re-transfer was reduced by increasing zeolite use. The other leaves have the main role of the dry matter re-transfer to the gain than the other parts (stem and flag leaf). In addition, its amount depends on the genotype and the environmental conditions and varied from -3.45 to 14.63%. The role of stems to transfer the dry matter to the grain was lower than the other aerial parts and in range of 2.5-16.7%. Totally, it seems that the re-transfer of the dry matter from the aerial parts of rice genotypes has an important role in filling the grains. Manuscript profile

      In order to investigate the effect of nitrogen and phosphorus fertilizers on yield and yield components of sweet sorghum, this research carried out in the research center of sugarcane and related industries in the form of split plots in the form of a randomized complete block design with three replications. The main factor included 50, 100 and 150 kg/ha of nitrogen and the sub plots included 60, 90 and 120 kg/ha of phosphorus. The results showed that the interaction effect of phosphorus and nitrogen consumption on sweet sorghum grain yield was not significant. The effect of nitrogen and phosphorus fertilizer treatments on biological yield, grain yield, 1000 seed weight and number of seeds per panicle was significant at the 1% probability level. The highest grain yield with 2500 kg/ha was assigned to the nitrogen treatment of 150 kg/ha and the lowest grain yield with 1900 kg/ha was observed in the nitrogen treatment of 50 kg/ha. The highest and lowest grain yields in phosphorus treatment were assigned to 120 (2300 kg/ha) and 60 (2000 kg/ha) of pure phosphorus per hectare, respectively. In general, the highest grain yield was observed in the fertilizer treatment of 150 kg of nitrogen and 120 kg of phosphorus, and the difference between this treatment and the fertilizer combination of 150 kg of nitrogen and 90 kg of phosphorus was not significant. Therefore, the second fertilizer combination was recommended to achieve optimal yield, although more research is needed in this regard. Manuscript profile

      In order to evaluate of weeds control at different levels of sulfur coated urea on yield and qualitative characteristics of sugar beet, a study was carried out as split plot design in randomized complete blocks design with four repetitions in Shoushtar region during 2016. Experimental treatments consisted of four different levels of sulfur coated urea (SCU) (0, 150, 180 and 250 kg.ha-1). The use of herbal treatments of chloropyralide + Des Modifam + Moeifam + Autophamousite and metamitron + Modifem + Autophamousite as a sub-agent. The results showed that weed dry weight was affected by different amounts of urea with sulfur coating and increased with increasing sulfur content of urea, which increased the weed weight of weeds, so that it was highest in application of the highest amount of urea with sulfur content per hectare with no weeding of weeds. The amount of 237 grams per square meter was obtained. Also, in the effects of fertilizer interaction and weed control, the highest yield of sugar beet (13421 kg) was attributed to full weed treatment and the highest application rate of sulfuric urea. The highest root yield of sugar beet (57004 kg ha-1) was related to weed control and application of the highest amount of sulfur urea. Among the weed control treatments, the highest root yield of sugar beet (46711 kg.ha-1) was obtained in metamitron + Des medifam + Autophamousite herbicide application and application of the highest amount of urea with sulfur content per hectare. Also, the highest percentage of pure sugar in the treatment of non-application of sulfur content of urea with non-control of weeds was 18.6% and 20.30%, respectively. In general, it can be said that Urea fertilizer with sulfur coating with the use of Médifam + Des Moiifam + Autophamousite + Metamitron has the optimum performance of sugar beet.   Manuscript profile

          Considering the salinity problem and limited water resources in Iran, joint application of salinity moderators and super absorbents, can be an effective approach to improve the growth indexes of plants, grown in saline soils. For investigating the effects of salicylic acid and pumice on yield and nutrients content in Cress (Lepidium sativum) in a saline soil, a field experiment was conducted in a factorial form on completely randomized design with nine treatments and three replications. The factors were 1) salicylic acid (s) including three rates, consists of a) no amendment (control), b) soaking seeds in salicylic acid 0.1 mM for 24 h and c) spraying plants by salicylic acid 0.7 mM in three stages and 2) pumice (p) including three rates, consists of a) 0 (p0), b)15 T/ha (p1) and c) 30 T/ha (p2). Results showed that seeds soaking in salicylic acid 0.1 mM could moderate the negative effects of salinity in Cress. But there was not a significant difference between spraying plants by salicylic acid 0.7 mM and control, in most growth indexes. Increasing pumice rate, increased Dw and P, Ca, Mg and K content and reduced Na content, prolin, H2O2 and ascorbat peroxidase in Cress. Totally P2S1 treatment or application of 30 T/ha pumice and soaking seeds in salicylic acid 0.1 mM, produced the most Dw and nutrients content and the leastsalinity stress indexes in Cress.

      Salinity is one of the growth limiting factors in agricultural. In order to determination of the most effective traits on soybean yield at different levels of salinity stress, a factorial experiment with 3 replications was conducted in greenhouse of Sari Agricultural Sciences and Natural Resources University in 2016. Treatments consisted of four soybean genotypes (Hill, Dayr, Ford and Williams), three levels of sulfur (control, 5 and 10 grams of sulfur powder) and three levels of salinity (control, 4 and 8 dS/m). Analysis of variance showed that simple effects of sulfur, genotype, salinity and interaction between sulfur and salinity were significant at 0.01 probability level. Correlation coefficients between studied traits showed that there was a positive and significant correlation between grain yield and all traits except for the Na+/K+ ratio. By using stepwise regression analysis in the control treatment, sulfur content, in 4 ds/m salinity, traits of Na+ percentage, fresh weight of shoot and seed protein percentage, and in salinity of 8 ds/m seed number per plant were entered in model. path analysis of grain yield showed the highest positive direct effect in the control, second level and the third level of salinity were sulfur content, Na+ and number of seeds per plant, respectively. The results of this study showed that the traits of sulfur content, Na+ percentage, fresh weight and protein percentage are the scales related to grain yield, which can be used as an indirect selection scale for genetic improvement of yield in saline regeneration programs.   Manuscript profile

      In order to investigate the effect of planting density and different irrigation regimes on the yield of pearl millet in Ahvaz, Iran, in 2017, was carried out. The experiment was conducted as a split-plot based on randomized complete block design with three replications. In this study, the irrigation regime was considered as the main-plot at three levels (90, 120 and 150 mm evaporation from class-A evaporation pan) and the plant density as the sub-plot at four levels (20, 30, 40 and 50 plants/m2). The results showed the irrigation regime had a significant effect on fresh and dry leaf weight, fresh and dry weight of stem, plant height, stem diameter, and chlorophyll a and b at 1% probability level. Also, the plant density had a significant effect on leaf fresh and dry weight, fresh and dry weight of stem, plant height and stem diameter at 1% probability level. The interaction of irrigation regime and plant density on leaf fresh and dry weight, fresh and dry weight of stem and plant height was significant at 1% probability level. In general, according to the results, it can be concluded that with increasing drought stress all measured traits decreased. Therefore, considering the environmental conditions of the experimental area as well as the economic aspects of applying and performing irrigation after 90 mm of the evaporation pan, treatment is more suitable. Also, among the densities studied, the density of 50 plants/m2 had the highest biological yield of total forage millet. As the final result, the best treatment was determined using a density of 50‌plants/m2 and irrigation after 90 mm evaporation from the evaporation pan.   Manuscript profile

      This experiment was conducted in factorial format and in the form of RCBD with 3 replications. The treatments used included four concentrations of salicylic acid and thiamine. Application of salicylic acid caused significant changes at 1% and 5% levels in all morphological and physiological traits except the number of flowers in the cluster, relative leaf water content, and acidity. Spraying salicylic acid on the leaves of tomatoes increased some traits such as yield, number of fruits in plant, number of bunches in plant, and compared to control plants (without application of salicylic acid). Thiamine spraying caused significant changes in most of the morpho-physiological and quality traits. Thiamine caused an increase in the traits that were significant, although this increase was influenced by the concentration of the used. The yield (4084 and 4225 kg for the application of salicylic acid and thiamine), vitamin C (42 and 51 mg/g fresh weight for the application of salicylic acid and thiamine), and lycopene (2.34 and 2.49 mg/g) fresh weight for the application of salicylic acid and thiamine) traits had the highest amount of salicylic acid and thiamine at a concentration of 100 mg/liter. Some of the traits such as yield, fruit diameter, fresh and dry weight, total acidity, phenolic acid, and vitamin C were also affected by the interaction of salicylic acid and thiamine. According to this study spraying of salicylic acid and thiamine with a concentration of 100 mg/liter will have the greatest effect on morphophysiological characteristics in Galaxy tomatoes under greenhouse conditions.

Rate of damaged seed in seed metering device, uniformity of planting depth, uniformity of seed distance on row, seed emergence and field capacity were measured for each machine. Results showed that in five parameters Gaspardo precision pneumatic planter had better result compared to the Barzegar Hamedan grain driller. This advantage was significant at in five parameters at 5% of probability. Gaspardo precision pneumatic planter than Barzegar Hamedan grain driller reduced the rate of seed damage at 3.83% and increased the rate of uniformity of planting depth, uniformity of seed distance on row, seed emergence and field capacity at the rates of 11.4, 39.3, 24.2 percent, 0.38 ha/hr respectively. Forward speed had no significant effect on the rate of damaged seed, uniformity of planting depth, uniformity of seed distance on row, but seed emergence significantly decreased and field capacity significantly increased with increasing forward speed.
