Abstract :
To investigate the effect of potassium and zinc spraying at different developing stages of vegetative characteristics and grain yield of barley under drought stress conditions, a split plot experiment was carried out in a randomized complete block design with three replications at the Agricultural Research Center of Khoy in which irrigation cutting at 3 levels ( full irrigation, irrigation cutting at milking stage, and irrigation cutting in the dough stage ) in main plots and potassium sulfate and zinc sulfate spraying at four levels ( spraying at the stemming + milking, stemming + dough, milking + dough, and stemming + milking + dough ) were considered as sub plots. The results of the experiment showed that irrigation was significant at 1% level for all traits. potassium and zinc sulfate spray were significant for all traits at 1% level. The occurrence of drought stress increased the barley protein content. The increase in irrigation cut treatment at the dough stage was the highest ( 31.10% ). In addition to the spraying surfaces, treatment B4 (spraying at stemming + milking + grain dough ) proved to be better than other treatments and increased grain yield from 3924 kg ha-1 in clustering treatment to 4824 kg ha-1 in dough treatment of the grain. Interaction effect of two factors was significant only on 1000 grain weight at 1% level. Keywords :
