In order to investigate the effect of Sykocel foliar application on the yield and yield components of wheat variety (Kohdasht) under drought stress conditions, An experiment was carried out at the station of the agricultural research, education and extension center of Ardabil province (Maghan) during the crop year of 2019-2019. The experiment was conducted as a factorial in the form of a randomized complete block design with three replications. The first factor includes psychocel with concentrations of zero (S1), 400 (S2), 800 (S3) and 1200 (S1) mg/liter and drought stress in 3 levels of full irrigation or control (D1), interruption of irrigation in Spikeing (D2) and stopping irrigation were in the seed filling stage (D3). The results showed that with the increase in the concentration of Psychocell, the height of the plant, the number of spikes per plant, the number of seeds per spike, the biological yield, the weight of one thousand seeds and the weight of the stem increased. In the condition of drought stress, the highest number of seeds per spike, spike per plant, 1000 seed weight and stem weight were obtained in the spike stage. In the stress of water shortage in the seed filling stage, the highest plant and stem height was obtained. The lowest number of seeds per spike, spike per plant, plant height, thousand seed weight, leaf weight and stem weight were observed in foliar spraying with a concentration of 0 mg/liter with the control treatment. Psychocel caused a significant increase in all traits compared to the control, which indicates an increase in plant resistance with the use of Psychocel, finally it seems that with foliar spraying with a concentration of 800 mg/liter and drought stress A higher yield can be achieved in the seed filling stage.
