Abstract	In order to investigation of foliar spraying of different concentrations of salicylic acid on corn (KS C400 var.) yield and yield components under drought condition, an ex periment was conducted based on Randomized Complete Block Design (RCBD) as Split Plot with three replications during 2011-2012 growing season at Sabzevar region , Iran. The treatments of drought tension were consisted of stress in 10-12 leaf stage, stress in flowering an d grain filling and salicylic acid treatments including 0, 0.5, 1 a nd 1.5 Mm concentrations. Results of variance analy sis showed drought stress reduced kernel yield, row no per ear , kernel no per row, cob diameter and ear length si gnificantly. The highest and lowest kernel yield was recorded fo r stress in 10-12 leaf stage (7.13 ton/ha) and stre ss in flowering (4.76 ton/ha). Means comparison revealed that the e ffect of salicylic acid spraying on the growth of m orphological traits and increasing in the corn yield was conside rable and significantly inhibited of decreasing in plant height, ear height, leaf area of the main ear, row no/ear, kern el no/ row and ear length. 1 Mm concentration of sa licylic acid at 10-12 leaf stage had the greatest impact on the rel ieving of drought stress. Results of simple correla tion showed kernel yield had a positive and significant correla tion with ear diameter, kernel no/row and ear heigh t. Considering the stepwise regression results, ear diameter, cob diameter and anthesis-silking interval (ASI) were t he most effective traits on kernel yield.
