In order to study the effect of nitrogen and irrigation interval on quantity traits and protein of mung bean (Vigna radiata L.), a factorial experiment based on randomized complete block design was conducted with three replications at research farm of Gonbad Kavous University during 2016. Interval irrigation factor was at three levels including irrigation each 10, 20 and 30-day, nitrogen fertilizer in three levels of non-application and application of 50 and 100 kg per hectare and mung bean genotypes in two levels of VC-1973A and Partov. The results showed that the highest grain yield was obtained from 30-day irrigation interval with 100 and 50 kg per hectare nitrogen and the lowest grain yield was obtained from 10–day irrigation interval and 100 kg nitrogen/ha and non-application treatment and also 20–day irrigation interval and non-application of nitrogen/ha. Grain yield in VC-1973A was 72.52% higher than partov gernotype. The highest protein percentage was obtained from irrigation interval of 30-day and the lowest was obtained from 10-day irrigation interval. With increasing of nitrogen consumption, protein percentage increased but proline decreased. Increasing of irrigation intervals from 10 to 30-day increased the amount of proline in mung bean genotypes. Protein percentage and amount of proline in Partov was 9.49% and 29.66% more than VC-1973A. In addition, although in some traits Partov was superior but in more traits especially grain yield VC-1973A was better than Partov and increasing of interval irrigation and nitrogen consumption created better conditions for mung bean production.

In order to investigate the effect of pea cultivars and planting pattern on yield and seed protein of pea, total yield and LER, a factorial experiment (two factors) was conducted in a randomized complete block design with three replications in research farm of Gonbad Kavous University during 2016-2017. In this experiment, two cultivars of pea (Poffaki (Aspersion) and Shamshiri (Swordfish)) and a native variety of spinach were used. Nine planting pattern i.e. sole pea and spinach, replacement series of 33, 50 and 67% spinach instead of pea and additive series of 33, 50, 67 and 100% spinach to pea. Effect of pea cultivar and planting pattern were significant on most of traits. Plant length, 100-seed weight, pod weight, pod yield per plant, fresh weight of pea plant and pod yield in Poffaki was higher than Shamshiri but number of pod per plant and harvest index in Shamshiri was higher than Poffaki. Number of pod per plant, pod weight, pod yield per plant, 100-seed weight, harvest index, and fresh weight of pea in sole pea and replacement series was higher than additive series. Addition of spinach in additive series reduced traits of pea but total yield increased. According to the results, yield of Poffaki cultivar was 11.81% higher than Shamshiri and the highest total yield with 30.1 ton/ha obtained from additive series of 100% pea + 100% spinach. Land equivalent ratio (LER) was over than 1 in all intercropping treatments that indicates the superiority of intercropping.

In order to assess the performance of two soybean cultivars produced in two regions including Karaj and Moghan to drought stress at reproductive stages and also the impact of drought stress on yield and its components, oil and protein percent, an experiment was conducted as a split factorial based on complete randomized block design in three replications in agriculture faculty of Tarbiat Modares University during 2014. Four treatments of drought stress were exerted as complete withholding irrigation at flowering stage (R1-R3), pod formation (R3-R5), seed filling stage (R5-R7) and control (no withholding of irrigation) which were placed in main plot and other treatments were two soybean cultivars (‘Williams’ and ‘L17’) and two seed production sources (Karaj and Moghan) that were placed in sub plots. The results indicated that the effect of drought stress on pod number, 1000-seeds weight, seed yield and also oil and protein percent was significant. The highest seed yield (262.73 gram per meter square) was observed in control (no stress) and the lowest yield (162.22 gram per meter square) belonged to drought stress at pod formation stage. Also the interactions of drought stress × cultivar and drought stress × seed source were significant on grain yield. The lowest seed oil percent (18.24 percent) and the highest protein percent (37.28 percent) of seeds were obtained at seed filling stage. With considering these results, the irrigation at pod formation stage (R3-R5) is necessary for preventing the reduction of soybean seed’s yield.
