A total of 375 fish with an average initial weight of 31.00±2.00 g were divided into five treatments including 0 (control), 25, 50, 75 and 100 mg kg-1 NA. Each treatment had three replications and each replication contained 25 pieces of fish that were randomly stored in 15 tanks with capacity of 200 liter and fed with food related to the same treatment for 60 days. The results showed that the highest percentage of weight gain (225.22±13.80) was related to the treatment of 75 mg kg-1 NA and the lowest (194.57±12.88) was related to the treatment of 100 mg kg-1 NA. Also, the highest daily growth rate (%) with 2.51±0.10 g d-1 was from the treatment of 75 mg kg-1 NA, which was significantly higher than the amount in the control (p <0.05). The highest rate of food efficiency was from the treatment of 75 mg kg-1 NA. The finding of the present study indicated that 83.61 mg NA has the best effect on the growth of rainbow trout and is recommended for culturing of this fish. Manuscript profile -

Timely herbicide application significantly increases herbicide efficiency. A field experiment was conducted to study the effect of Nicosulfuron timing and dose on S. halepense competition with maize. Experiment was split-plot in three replications. Main plots were herbicide dose of 0, 1, 1.5, 2, 2.5 kg/ha and sub plots were herbicide timings of 2-4 l, 4-6 l, 6-8 l of maize growth. Growth parameters of maize including height, leaf area (LA) and total biomass (TB) were measured. Results showed, the highest height, LA and TB were obtained from Nicosulfuron application at 1.5 Kg/ha in 2-4 l of maize and no significant difference was shown to herbicide recommended dose or higher. With delay in herbicide application, the height and TB of S. halepense increased and its competition with maize got raised. It caused decrease in maize growth indices. Current study showed main effect of herbicide dose in changing weed-crop interactions. Successful management would change competition in advantage to crops using lower herbicide doses to achieve both economic and environmental purposes in sustainable crop protection.

The treatments included five sowing dates (9th of April, 21th of May, 18th of June, 30th of June and 15th of July) and the cultivar of Karoun (single cross 701) used. In each of the 5 to 7 day periods of each plot, 5 plants were randomly selected and the traits studied in connection with this study included: total dry weight, leaf area and leaf dry weight to draw the curve of physiological growth indices of maize plants during the growing season. The results showed that the effect of sowing date was significant on the maximum leaf dry weight, total dry weight, leaf area index (LAI), relative growth rate (RGR), crop growth rate (CGR), specific leaf area (SLA) and fresh yield. In the meantime, the fourth sowing date (30th of June) had the highest maximum leaf dry weight, total dry weight, leaf area index, CGR and fresh yield, and the second sowing date (21th of May) was superior to the rest of the sowing dates in terms of maximum RGR and SLA. The CGR was reduced in different sowing dates after reaching its maximum and eventually became negative. According to the results of this study, maize sowing in the first decade of July can be recommended for Varamin region. Manuscript profile -

The experiment was carried out in a split-factorial arrangement of treatments based on randomized complete block design with three replications. The main plots consisted of three levels of irrigations (irrigating after 60, 90 and 120 mm evaporation from class A evaporation pan). Two levels of nitrogen replacement with phosphorus and without replacement and two levels of phosphorus replacement and without phosphorus replacement assigned to subplots. The results showed that simultaneous replacing of nitrogen and phosphorus in all irrigation levels increased physiological growth indices of leaf area index, dry matter accumulation, crop growth rate, relative growth rate and net assimilation rate. Moisture stress reduced growth rate of the crop significantly. Results also showed that crop growth rate increased 35 to 45 days after planting and reached to its maximum level after 65 days after planting date. After this period, the crop growth rate of soybean decreased and reached to zero about 95-100 days after planting. The highest dry matter accumulation and crop growth rate were obtained from irrigation after 60 mm evaporation and nitrogen-phosphorus simultaneous placement application. According to the results, simultaneous replacing nitrogen and phosphorus, reduced the negative effect of moisture stress on soybean growth indices. Nitrogen replacement with phosphorus increased grain yield by 11.4% as compared to non-replacement of nitrogen with phosphorus and yielded 3855.88 kg.ha-1. In this research, nitrogen replacement with phosphorus under irrigation after 90 mm evaporation prevented significant oil yield loss as compared to irrigation after 60 mm evaporation.

Different levels of water irrigation (full irrigation, stress before tasseling and stress after pollination and embryo formation) were measured assigned to main plots and maize hybrids (SC500, SC582, SC647, SC666, SC700 and SC704) to subplots. To determine growth indices including leaf area index, crop growth rate, dry matter accumulation, relative growth rate and net accumulation rate means of 14 times sampling were calculated. Results indicated that growth trend for leaf area index, crop growth rate, dry matter accumulation, relative growth rate and net accumulation rate in corn hybrids were similar, but they were different for levels of irrigation significantly. In such a way that drought stress decreased growth indices. The highest growth indices were obtained from full irrigation and lowest values from drought before tasseling. Manuscript profile -

SC 604) to using plant growth promoting rhizobacteria (PGPR) and phosphate solubilizing microorganisms (PSM) and rhizobacteria, a field experiment was conducted during 2008. The study was arranged in split plot experiment based on randomized complete block design with three replications. Three levels of manures, consisted of 20 Mg.ha-1 farmyard manure, 15 Mg.ha-1 green manure and check or without any manures assigned to main plots and eight levels of fertilizer combinations (consisted of 1-NPK or recommended fertilizer application; 2-NPK+PSM+PGPR; 3-NP50%K+PSM +PGPR; 4-N50%PK+PSM+ PGPR; 5-N50%P50%K+PSM+ PGPR; 6-PK+PGPR; 7-NK+PSM and 8-PSM+ PGPR) to sub plots. Results showed that the maximum dry matter (13/2 g.m-2), leaf area index (3/8) and crop growth rate (34/5 g.m-2.day-1) were, produced by using both farmyard manure and application of NPK plus biofertilizers. Application of green manure and biofertilizer significantly increased dry matter by 11% compared to control. Meanwhile, farmyard manure and green manure application markedly increased the leaf area index by 17 and 10%, respectively. NPK treatment in farmyard manure plots and inoculation of PGPR and PSM significantly increased crop growth rate in corn plants compared to green manure and control plots. However, inoculation of biofertilizer and reducing P application by 50% did not significant influence growth indices such as total dry matter accumulation, leaf area index, and crop growth rate significantly. In conclusion, it seems that biofertilizers could be recommended as an effective option to reduce phosphate chemical fertilizers, improve the growth indices of corn plants, which ultimately result in grain yield increase.

Experiment factors consisted of two dry land wheat cultivars (Cross Sablan and Saji) and fertilizer levels were 1- without application of phosphorous (P), 2- 100% phosphorous application, 3- Pseudomonas putida, 4- Funeliformis mosseae, 5- P. putida + F. mosseae, 6- P. putida + F. mosseae + 50% of phosphorious fertilizer, 7- P. putida + 50% of phosphorious fertilizer and 8- F. mosseae + 50% of phosphorious fertilizer. Results indicated that using chemical and biofertilizer affected 50% days to emergence, stem elongation, flowering, pollination, maturity weight and maturity significantly. Results also showed that using of bio-fertilizer reduced drought stress effects by improving phonological traits of wheat under dry land conditions. The highest LAI, CGR, TDM, RGR and NAR were obtained by Saji cultivar and application of 50% of phosphorious fertilizer + Mycorrhiza fungi, but it effect at late season on CGR, RGR and NAR due to increased shading of plants and leaf falling were negative. The Saji cultivar and 50% of phosphorious fertilizer + F. mosseae because of maximum LAI, CGR and TDM produced higher grain yield under dry land conditions. It can be concluded that Saji cultivar along with F. mosseae may have higher growth indices and seed yield under dryland conditions. Manuscript profile -

The experiment was split-plot, based on a complete randomized block design with four replications. The main plots consisted of four moisture levels: (20% FC), (40% FC), (60% FC) and (80%FC) and sub-plot of four rates of nitrogen fertilizer applications: 150, 200, 250 and 300 kg.ha-1. Results showed that with increasing nitrogen fertilizer levels, LAI, NAR, SLA and RGR were also increased, but under lower moisture regimes they were decreased. The lowest and highest growth indices belonged to 80% and 20% water depletion, respectively. The lowest CGR index was obtained at 80% water depletion and 150 and 300 kg nitrogen ha-1. LAR increased at the intial growth period and then decreased. Positive relationships between seed yield and growth indices were also observed. At FC 20% and 300 kg N ha-1 treatment highest grain yield was obtained and growth indices were also in the highest values. In general, nitrogen application increased all traits. However, there were not significant differences between 250 and 300 kg N ha-1on the traits under study. It seems that nitrogen fertilizer mitigates the negative effects of water deficiency. Application of 250 kg of nitrogen fertilizer had the highest effect on all levels of moisture content. Manuscript profile -

In MoreDetermination of crop NPK requirements is important for proper crop growth. To determine the NPK nutrition of henna (Lowsonia inermis L.), a factorial experiment based on randomized complete block design was carried out in the Shahdad, Kerman province, in 2015-2016. In this study, response of three henna ecotypes (Bam, Shahdad and Roodbar) with four fertilizer combinations consisting of nitrogen, phosphorus and potassium (N: K: P, 0: 0: 0, 100: 50: 50, 200: 100: 100, 300: 200: 150 kg/ha) were investigated for some growth indices like CGR, RGR, net photosynthesis, transpiration rate and stomatal conductance. The results indicated that the highest mean of CGR, RGR, net photosynthesis, transpiration rate, stomatal conductance and total dry yield belonged to Shahdad ecotype. While, there was no statistically significant difference between the Shahdad and Roodbar ecotypes for leaf dry yield. The effect of NPK nutrition treatment on the most of traits measured was significant at 1% probability level. The highest mean of traits measured belonged to NPK combination of 300: 200: 150, while the difference was not significant from 200: 100: 100 for leaf dry yield and RGR. In this study, the interaction of ecotype and nutrition was not significant for the traits under study. Therefore, according to the results, it can be concluded that Shahdad and Roodbar ecotypes and combinations of nitrogen, phosphorus and potassium fertilizers with a ratio of 200: 100: 100 are appropriate for henna in Shahdad climatic conditions.

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.

To MoreWater stress is one of the most important environmental factors limiting the growth and yield of plants, especially in arid and semi-arid regions. Bio-stimulants are biological substances that stimulate metabolism and metabolic processes to increase plant efficiency. To investigate the effects of low water stress and bio-stimulants of Fosnutren and Humiforte on some morphophysiological and phytochemical traits of thyme, a factorial experiment based on a completely randomized design with 12 treatments and 3 replications in 2020 performed in greenhouse conditions. Therefore, the seedlings obtained from seed cultivation after two weeks of transfer to the pot, were exposed to dehydration stress treatments (25, 50, 75 and 100% of field capacity). Foliar application of plants with Fosnutren and Humiforte (5 ml) was performed three times and once every 15 days. The desired traits were evaluated 15 days after the last treatments. The results showed that increasing the levels of low water stress (25 and 50% of field capacity) caused a significant decrease in growth indices, chlorophyll content, total antioxidant percentage and essential oils and increase in proline content. Simultaneous treatment of drought and bio-stimulants of Fosnutren and humiforte with significantly reduced oxidative stress due to dehydration improved the evaluated traits except the amount of proline. The highest percentage of essential oil (2.34%) in Fosnutren foliar spraying and was obtained at 75% field capacity. In general, foliar application of Fosnutren and Humiforte reduced the negative effects of dehydration in thyme. Manuscript profile
