Abstract :

Water deficit is one of the most factors limiting of yield in wheat. In order to effects of irrigation deficit and factors of drought stress modulate on some agronomic of line C7814 ,the experimental was conducted in a strip plot arrangement based on randomized complete block design with three replications in research field Islamic Azad University of Arak in 2009-2010 cropping seasons. Experimental factors were including of irrigation at two levels: control and cut irrigation at spike emergency and factors of drought stress modulate in five levels: control, salicylic acid, selenium, micro elements, salicylic acid and selenium, salicylic acid and selenium and micro elements. The results showed that irrigation deficit decreased agronomic traits and grain yield. Application of factors  of drought stress modulates decreased the height of plant, but traits of weight of spike, number of spike per area, biological yield, harvest index and grain yield were increased. Interaction effects of treatment showed that application of factors drought stress modulates increased grain yield by 8% and 5 % in full irrigation and cut irrigation at spike emergency as compared with control, respectively.
