Abstract

In order to study effect of stress, different amounts of NITROGEN and distribution methods (Tfsyt) on grain yield, dry matter and THIS TRANSFER rate is photosynthesis Corn hybrid SC 704 climatic conditions in Khuzestan (Ramin) in the summer of 1383 on the farm Research University of Agricultural Sciences and Natural Resources Khuzestan was conducted, this study included three independent experiments as split-plot design was a randomized complete block basis. Each experiment was repeated Tuesday. In this experiment a level of irrigation was applied separately. Optimum irrigation, land and mild stress stress Severe stress (irrigation after leaving respectively 50, 75 and 100 percent of the plant used for soil moisture). In this experiment NITROGEN as the main treatment with three levels 140, 180 and 220 kg NITROGEN per hectare and NITROGEN distribution method (Tqsyt) as the sub-plots with three levels (1S: 50 percent + 50 percent of the plant during the six leaves, 2 S: 25 percent + 75 percent of the plant when six leaves and 3 S: 25 percent + 50 percent of the plant when six leaves + 25 percent during the twelve leaves), respectively. Analysis of variance showed that compound Effect of water deficit stress, NITROGEN and NITROGEN on grain yield and Tqsyt was significant. Intensity of drought stress grain yield decreased. This decrease mainly due to reduced grain number and grain weight of maize. NITROGEN consumption increase in grain yield. Performance difference between different levels NITROGEN primarily related to the positive effect of NITROGEN in increasing the number of seeds per ear.. Tqsyt N 3 S with grain yield and grain number ear to significantly Tqsyt 1 S increased. With increasing water deficiency in soil NITROGEN positive effect on increasing grain yield significantly decreased. Minimum and maximum transfer rate of this photosynthetic materials were favorable to the irrigation treatments were dry and mild stress. Intensity of drought stress and reduced use of NITROGEN and photosynthesis rate is Tqsyt 1 S showed a significant decrease. Efficiency and share resources in the production of vegetative parts yield stress increased with increasing severity and photosynthesis efficiency and decreases the share of cholera increased share of NITROGEN is increased photosynthesis.
