The current study was carried out to ditermine the effect of different levels of salicylic acid (SA) on yield and some physiological characteristics of sweet corn hybrids under water stress, using split plots in the base of randomized complete block design with three replications. Treatments were included water stress and salicylic acid both at three levels and three hybrids of sweet corn (pashen, basin and chalenjer) respectively as main plot, sub plot and sub sub plots. The results showed that the effects of water strees were significant on all traits. The effect of SA was significant on most traits except catalase including canned yield, forage fresh weight, forage dry weight, eair wet yield, 1000 seeds weight, a cholorophyll, b cholorophyll and peroxidase. The effect of hybrids were significant on canned yield, wet and dry forage yield and "a" chlorophyll content of leaf and were not significant on other traits. The interaction between water stress, salicylic acid and hybrids were significant on all traits. The maximum amount of canned yield, forage wet weight, weight of forage dry, fresh ear yield, were obtained  respectively 1455, 4541, 1123 and 2749.3 gr/m2 when the three following treatments, irrigation after drainage 50% available soil water, SA 0.5 ml molar and pashen hybrid were combined. In general the results showed that application of SA relatively reduced the negative effects of water deficit stress.
