Application of plant growth regulators is one of the most important methods to reduce the effects of drought stress to obtain suitable growth under water deficit conditions. The currecnt research objective is investigat the effect of cycocel foliar application on alleviation of drought stress concequences on growth traits of barley cv. Kavir .The experiment was conducted as factorial in randomized complete block design with four replications. The experiment treatments included cycocel with concentrations of 500, 1000, 1500 mg/L, drought stress at three levels of normal irrigation, irrigation cut-off in stemming and flowering stage. Drought stress negatively affected all evaluated traits. Cycocel application under drought stress significantly increased yield and yield components and reduced plant height. Foliar application with 1500 mg/L concentration of cycocel caused the plant to be subjected to drought stress. Applying 1500 mg/L cycocel can be recommended to reach optimum grain yield of barley cv. Kavir subjected in drought stress.
