To study effects of seed priming and foliar application of salicylic acid (SA) on some of the Morphological traits under drought stress condition a field experiment was conducted at College of Agriculture, University of Zanjan in the spring of 2012. The experiment was conducted as a split plot based on complete randomized block design with three replications. In this study drought stress at reproductive stage with control (full irrigation) were assigned to the main plots and different treatments of seed priming and foliar application with SA include dry seeds (Without priming), seeds priming with SA at different concentrations (0, 800 and 1600 μmol) and foliar application with SA at different concentrations (800 and 1600 μmol) were assigned to the subplots.Results showed that the highest biological yield and lateral branch were obtaind in full irrigations and foliar application with SA at the concentration of 1600 μmol and the result also showed that effect of drought stress and seed priming and foliar application of salicylic acid on main branch and harvest index was significant and The highest main branch and harvest index were obtained in foliar application with SA at the concentration of 1600 μmol and the lowest amount obtained in dry seed.
