Abstract
In order to investigate the effect of applying super absorbent polymer on yield, yield components and qualitative and quantitative characteristics of corn hybrid NS640 under irrigation cut tension conditions, this experiment was conducted in the form of split plots in randomized complete blocks design in three replications in 2013-14 cropping year. The main plots contained irrigation in four levels normal, irrigation cut at stem formation stage, irrigation cut at the tassel appearance stage, irrigation cut at ear flowering appearance stage and super absorbent polymer at three levels including non-applying super absorbent, applying 15 kilogram per hectare super absorbent and applying 30 kilogram per hectare super absorbent in sub plots were compared. The obtained results indicated that the simple effect of water deficit tension was significant on all experimented traits: the number of grain in corn, one thousand-grain weight, grain yield, biologic yield, harvest index, relative water content and protein percentage. Also, the simple effect of super absorbent on all traits was significant excluding the traits one thousand-grain weight, harvest index and relative water content. On the other hand, the interaction of water deficit tension and super absorbent became significant on the number of grain in corn and grain yield. The maximum grain yield equals to 1063 gram per square meter was related to normal irrigation and applying 30 kilogram per hectare super absorbent and among yield components the maximum number of grain in corn with 340/7 was related to this treatment, as well. The maximum amount of protein 9/79 percent was obtained at irrigation cut treatment in ear appearance stage. With regard to the obtained results, in irrigation cut tension conditions it was found that applying super absorbent causes improving the quantity characteristics of corn. As a result in these conditions consuming 30 kilogram per hectare of super absorbent for corn was recommended.

Abstract
To investigate the effects of foliar application of glycine betaine and micronutrients of zinc and manganese on morpho-physiological traits of red bean plant under salinity stress conditions, an experiment as a factorial form in randomized complete design with three replications in the Faculty of Agriculture, Islamic Azad University, Varamin-Pishva Branch in 2019 was contacted. Experimental factors included salinity at control, 3, and 6 dS.m-1 levels, glycine betaine at application (50 mg/Lit) and non-application levels and micronutrients included zinc (50 mg/Lit), manganese (50 mg/Lit), and the combined usage (25+25 mg/Lit). The obtained results indicated that salinity stress reduced the plant height (30.31 percent), number of pods per plant (48.05 percent), number of seeds per plant (37.85 percent), seed total weight per plant (25.08 percent), SPAD index (42.98 percent), and seed protein percent (31.2 percent) and increased proline amount (43.37 percent). In general, the most effect in 6 dS.m-1 salinity was observed. The application of glycine betaine was associated with improved yield and yield components and increased SPAD index (17.28 percent), seed protein percent (6.78 percent), and proline (37.71 percent). Micronutrient foliar application showed the increasing of yield and yield components of red beans, SPAD index (29.7 percent), seed protein percent (20.67 percent), and proline (55.31 percent). In general, the most effect was obtained in the application of zinc with manganese. The results showed that the use of glycine betaine along with zinc and manganese increased proline and SPAD index increased salinity stress tolerance in red beans. It was also observed that the effect of micronutrients was greater than glycine betaine on red beans under salinity stress.
