OBJECTIVES: This study was conducted with the aim of evaluating the effect of drought stress and potassium sulfate application on the crop production and qualitative traits of mung bean genotypes. METHODS: Current research was done according a factorial split plot based on randomized complete block design with three replications at two years in the summer of 2010 and 2011 at the Safiabad Agricultural Research Center, Dezful. Different irrigation levels (irrigation after 120, 180 and 240 mm of evaporation) belonged to main plot and potassium fertilizer (without fertilizer consumption, 37.5 and 75 kg.ha-1 from potassium sulfate source) with genotype (included the varieties of Parto, Indian mass and the promising lines VC6173, KPS1, Cn95) were placed in subplots. RESULT: The results showed that water deficit stress significantly affected the yield traits, stomatal conductance, harvest index and the amount of chlorophyll, so that severe and mild drought stress reduced the seed yield by 30.4 and 21.9%, respectively, compared to the optimal conditions. Among genotypes, the highest seed yield belonged to Pratto variety and VC6173 line were selected under optimal irrigation conditions and lowest one was related to KPS1 line. The use of potassium fertilizer increased the tolerance of all genotypes to drought stress. The use of potassium sulfate is due to its positive effect on the better absorption of other elements, especially nitrogen and phosphorus and increased tolerance to drought stress was effective. In general, drought stress had a significant negative effect on physiological traits of mung bean, and these characteristics also had a significant effect on the components of seed yield, so, potassium consumption had a positive and significant effect on physiological characteristics of the plant and Improved yield components. CONCLUSION: Optimal irrigation, potassium consumption of 37.5 kg.ha-1 and use of Pratu variety, Indian mass and promising VC6173 line were recommended. Manuscript profile -

Potassium is an essential nutrient that affects most of the biochemical and physiological processes are involved in plant resistance to biotic and a biotic stresses. OBJECTIVES: This study was conducted to assess effect of different pattern of irrigation and several source of potassium on crop production and morphological traits of corn. METHODS: This research was carried out via split plot experiment based on randomized complete blocks design with three replications along 2015 year. The main factor included three level of Irrigation regime (I1: Conventional Irrigation or Control, I2: Fix furrow irrigation, I3: Alternate furrow irrigation) and three level of potassium (K1: 100 kg.ha-1 Potassium sulfate base application or Control, K2: 10 kg.ha-1 Solo potash with first irrigation, K3: 100 gr.ha-1 PotaBARVAR-2 as a biofertilizer + 50 kg.ha-1 Potassium sulfate base application) belonged to sub factor. RESULT: The results showed that in different irrigation patterns, application K3 treatment with alternate furrow irrigation increased the seed yield and its components. Under deficient irrigation conditions, the plant height, length and diameter of ear were reduced and the application of K3 treatment with alternate furrow irrigation led to increase above traits. The highest number of rows per ear (16.6) and number of seed per row (28) were obtained from the interaction effect of normal irrigation and K3 treatment. The lowest number of row per ear (12.2) was due to the fix furrow irrigation and K2 treatment. The highest (237.5 gr) and lowest (213.5 gr) amount of 1000-seed weight belonged to I1K3 and I2K2 treatments, respectively. Also the maximum (5463 kg.ha-1) and minimum (2966 kg.ha-1) amount of seed yield was achieved from I1K3 and I2K2 treatments, respectively. CONCLUSION: Alternate furrow irrigation showed a significant advantage over the fix furrow irrigation after control with K3 treatment had the highest seed yield. Generally use of 100 gr.ha-1 PotaBARVAR-2 as a biofertilizer + 50 kg.ha-1 Potassium sulfate base applications with alternate furrow irrigation can be advised to farmers. Manuscript profile -

Chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and crab shells. Water stress is one of the most important abiotic stresses that affects plant physiological and morphological traits. In order to study the effects of chitosan foliar spraying on total chlorophyll, seed yield and its components of wheat under water stress conditions a split plot experiment based on randomized complete block design with three replications was conducted at Agricultural Research Center of Roudhen Islamic Azad University in 2017. The main plots included different irrigation regime at three levels (I1: normal irrigation, I2: water stress at heading stage, I3: water stress in grain filing period) and chitosan foliar application at tillering and stem elongation stages by three concentrations (C1:0, C2: 0.05%, C3: 0.1% chitosan in acetic acid is 1%) was belonged to sub plots. The results of analysis of variance showed that yield and its components in normal irrigation conditions have the best result and drought causes damage to the plant. The use of chitosan in the form of spraying had positive effects on some of the important characteristics of the wheat. Lowering the plant height, total chlorophyll, yield and yield components, as well as growth and development under drought stress conditions, are partially offset by the use of various concentrations of chitosan. The effect of chitosan on growth and yield of plant can be attributed to the production of plant hormones. The results of mean comparison showed that the highest economic yield was related to consumption of chitosan 0.1% in normal irrigation (6495.199 kg.ha-1) and The largest reduction of economic yield was observed under water stress in seed filing stage and in the absence of chitosan application (1511.49 kg.ha-1). The use of chitosan and normal irrigation has increased 76% to economic yield than control. It is concluded that foliar application of chitosan at vegetative stage enhanced the plant growth and development, which resulted from increased fruit yield in wheat. Among the concentrations, 0.1 percentages had superiority for plant growth, yield components and seed yield than the others. Finally its recommend that in the region under drought stress conditions, foliar application chitosan will be useful. Manuscript profile -

OBJECTIVES: Current study was done to evaluate effect of Different level of Concentration and Time of Application Gibberellin on crop production and growth indices of Canola genotypes. METHODS: This research was done via combined analysis split plot factorial experiment based on randomized complete blocks design with three replications along 2015-16 and 2016-17. The main factor included different level of canola genotype (Hyola401, RGS003, Jerry) and sub factors consisted different concentration of gibberellin hormone (0, 50 and 100 mg.l-1) and different time of application of gibberellin hormone (Planting, vegetative phase before flowering, flowering until pod emergence). RESULT: According result of analysis of variance effect of genotype, concentration and time of application gibberellin on studied traits was significant at 5% probability level (on seed yield at 1%) but interaction effect of treatments was not significant. Mean comparison result of different level of genotype indicated that maximum studied traits were noted for Hyola401 and minimum of those belonged to Jerry. As for Duncan classification made with respect to different level of Gibberellin Concentration maximum and minimum amount of studied traits belonged to 100 ppm and control. Between different levels of time of gibberellin application the maximum studied traits was observed in vegetative phase and the lowest ones were found in ripening phase. CONCLUSION: Finally according result of current research application Hyola401 in amount of 100 ppm Gibberellin Concentration at Vegetative Phase had the highest amount of growth indices and seed yield and it can be advice to producers in studied region.

OBJECTIVES: This study was conducted with the aim of evaluating the effect of drought stress and potassium sulfate application on the crop production and qualitative traits of mung bean genotypes. METHODS: Current research was done according a factorial split plot based on randomized complete block design with three replications at two years in the summer of 2010 and 2011 at the Safiabad Agricultural Research Center, Dezful. Different irrigation levels (irrigation after 120, 180 and 240 mm of evaporation) belonged to main plot and potassium fertilizer (without fertilizer consumption, 37.5 and 75 kg.ha-1 from potassium sulfate source) with genotype (included the varieties of Parto, Indian mass and the promising lines VC6173, KPS1, Cn95) were placed in subplots. RESULT: The results showed that water deficit stress significantly affected the yield traits, stomatal conductance, harvest index and the amount of chlorophyll, so that severe and mild drought stress reduced the seed yield by 30.4 and 21.9%, respectively, compared to the optimal conditions. Among genotypes, the highest seed yield belonged to Pratto variety and VC6173 line were selected under optimal irrigation conditions and lowest one was related to KPS1 line. The use of potassium fertilizer increased the tolerance of all genotypes to drought stress. The use of potassium sulfate is due to its positive effect on the better absorption of other elements, especially nitrogen and phosphorus and increased tolerance to drought stress was effective. In general, drought stress had a significant negative effect on physiological traits of mung bean, and these characteristics also had a significant effect on the components of seed yield, so, potassium consumption had a positive and significant effect on physiological characteristics of the plant and Improved yield components. CONCLUSION: Optimal irrigation, potassium consumption of 37.5 kg.ha-1 and use of Pratu variety, Indian mass and promising VC6173 line were recommended. Manuscript profile
