This research in the form split plot in format of random complete block design in three replays was implemented. The main plots consist of three levels of potassium sulfate fertilizer, 1- no potassium sulfate, 2- 70 kg/ha pure potassium 3- 140 kg/ha pure potassium, from the source potassium sulfate fertilizer, and subplots inclusive three levels of super absorbent polymer with amounts: 1- no super absorbent, 2- 50 kg/ha super absorbent, 3- 100 kg/ha super absorbent. The results showed Increased potassium sulfate up to 140 kg/ha and super absorbent up to 100 kg/ha cause improvement and increase total dry matter process, leaf area index, crop growth rate and net assimilation rate were. The difference between levels of potassium sulfate fertilizer was also significant in terms of  number of pods per plant, number of seeds per pod, 1000 seed weight, grain yield, biological yield at 1% probability level and harvest index at 5% level. The difference between super absorbent polymer surfaces in all measured traits was significant at 1% probability level. In the interaction between potassium sulfate and super adsorbent, 1000 seed weight, grain yield, biological yield at 1% probability level and harvest index were significant at 5% probability level, but In the remaining traits no significant difference was observed. The highest grain yield with 140 kg/ha of potassium sulfate and 100 kg/ha of super absorbent polymer with 4336 kg/ha and the lowest grain yield in control treatment (without application of potassium sulfate and superabsorbent) with 1334 kg/ha. According to the results, application of 140 kg ha-1 of potassium sulfate and 100 kg ha-1 of super absorbent polymer in terms of physiological indices and yield the results are acceptable and can be recommended in the region.

Abstract: Considering the increasing trend of salinity development and lack of desirable land for agriculture in the world, the use of saline resistant species or the use of compounds that reduce the effects of salinity stress and induction of resistance to stress in plants is very important. Salicylic acid is one of the beneficial compounds for plants, which plays an important role in the resistance of plants to environmental stresses, including salinity stress. To evaluate the potential beneficial effects of salicylic acid on some of the physiological and morphological parameters of an experiment, a factorial experiment was conducted in a completely randomized design with two factors: salinity including sodium chloride at 0, 100 and 150 mM and salicylic acid at two levels 0 and 1 mM with four repeats. At the end of experiment, vegetative traits, chlorophyll a, b, total, carotenoids, starch, sucrose and total protein content were measured after 28 days of treatment. The results of salinity and salicylic acid interaction showed that salinity significantly reduced the weight and dry weight of the shoot, root dry weight and root, root penetration depth, and the height of the forage plant. Salinity of 150 mM significantly reduced the amount of chlorophyll a and b. In addition, the amount of sucrose and starch and protein decreased by salinity. Treatments with salicylic acid increased vegetative traits, sugars, chlorophyll, carotenoids and protein under salinity stress significantly. Manuscript profile

To increase the competitive ability of wheat with weeds by the interaction effect of essential, extract allelopathic (Artemisia sieberi) and nano an experiment was conducted in Alborz, Karaj in 2016 as a factorial experiment in randomized complete block design with three replications. experimental treatments including Artemisia essential, extract allelopathy in six levels: essential of 0.6, 0.4 and 0.2 ml/m2, and extracts 0.6, 0.4 and 0.2 ml/m2, control with weed (non-use of allelopathic compounds), weed control (weeding) and Nano ZFMB (Zinc, Iron, Manganese & Boron) Nano at three levels: Nano, one Lit.haˉ¹, two Lit.haˉ¹of, a control (no use of Nano).The results of this study showed that essential oil treatment of 0.6 ml/m2 with consumption of two Lit.haˉ¹ Nano reduced 73.33% of total dry weight of weeds compared to the control of presence of weed. As a result, conditions for proper plant growth were provided. Nano effects have a more positive effect on wheat growth and the plant maintains the balance in the production of grains and straw by producing an adequate shoot. Also, in reducing the competition of weeds on wheat, the allocation of photosynthetic photos to the seed was more than straw. This increased 55.83% of wheat yield compared to the control of presence of weed. Manuscript profile

Broadleaf weeds are problematic plant species in the most agricultural fields. Echo-physiological traits of weed species, such as characteristics of seeds germination and their responses to different environmental conditions are very important. In order to study the effect of environmental conditions on weed germination, a study was carried out at laboratory and farm of Faculty of Agriculture, Ferdowsi University of Mashhad. The effect of irrigation regimes and sowing dates on weed specie Solanum nigrum L. were studied for two years during 2009-2010. Field experiment was designed as factorial experiment based on randomized complete block design (RCBD) with three replications. The first factor was three dates of planting (2009/6/23, 2009/7/24, 2009/8/24) and the second one included three irrigation regimes, alternative, every two days, every three days. Laboratory experiment was done in completely randomized design with three replications during 2010. Results showed that all of studied features, dormancy and cardinal temperatures were affected by experimental treatments. With increasing the interval between irrigations, germination characteristics of all studied species were decreased significantly. Of course, the reduction at the beginning stage of growing plant (15 days after growing) toward the end of growing season had gradually fewer effects. The results showed that the effect of environmental conditions were the most effective factor on speed of seed germination. Also, the percentage of seed germination was significant. Therefore, with increasing irrigation interval and delaying in planting date, seed germination characteristics decreased. Manuscript profile

Salinity, especially in arid and semi-arid regions, is one of the major agricultural issues around the world. Vermicompost has high levels of potassium, phosphorus and sodium, which leads to increased salinity. High salinity is a limiting factor in the consumption of this substance. Calcium ions have significant effects on plant physiological processes and improves the morphological and biochemical parameters of plants subjected to salinity stress (NaCl). To investigate the effect of calcium on the improvement of damage caused by vermicompost salinity as the experiment was conducted as a completely randomized design in autumn 2014 in a research greenhouse of Faculty of Agriculture, Ferdowsi University of Mashhad. In this experiment, calcium nitrate (99%) was used as a calcium source. The treatments consisted of calcium vermicompost control, 10mM calcium treated before seeding, 25mM calcium treatment and 75mM calcium treatment with culture medium. The results of this experiment showed that calcium presence had a significant effect on salinity effects and 10mM calcium had the most positive effects on the growth characteristics of cucumber in vermicompost culture medium. The proper application of calcium ion reduces the sensitivity of plants to salinity and improves the desired parameters, therefore, the use of crops with high calcium application efficiency can help reduce economic costs against salinity.

This experiment was conducted based on factorial layout with completely randomized block design with 3 replications. The first factor was humic acid fertilizer in three levels (0, 50 and 100 mg/L) and the second factor was salicylic acid at 3 levels (0, 2 and 4 mM). The results showed difference between the levels of Humic iron fertilizer in terms of number of seeds per pod 1000 seed weight, grain yield, biological yield and harvest index at 1% level of probability. The difference between salicylic acid levels was significant in all traits measured at 1% level. In interaction, number of pods per plant and grain yield were significant at 5% probability level, but no significant difference was observed in the remaining traits. The highest grain yield in the interactions of humic acid and salicylic acid was observed in treatment of 100 mg/l humic acid and 4 mM salicylic acid with 2793 kg/ha and the lowest in control treatment with 1033 kg/ha. The highest number of pods per plant was related to treatment with 100 mg / l humic acid and 4 mM salicylic acid with 25 pods per plant and the lowest in control treatment with 15 pods per plant. According to these results, application of concentration of 100 mg/l of humic acid and 4 mM salicylic acid in comparison to other treatments improves the growth analysis and increases the yield and components and is recommended in the region as well.    Manuscript profile
