Abstarct: This study aimed to investigate the effect of ultrasonic waves and salicylic acid on the growth and yield of maize under drought stress conditions in the Agricultural Faculty of the University of Shahrood in 1394, as split plot factorial randomized complete block design with three replications have done .Treatments include ultrasonic waves, at three levels of control, 4 and 8 minutes of irradiation with waves of 24 kHz frequency, salicylic acid control (tap water injection plant) and sprayed at a concentration of one mM, a week after flowering, a week after the dough and drought in three levels: control (irrigation) and irrigation and irrigation from flowering to the dough on.Results showed a significant effect of reducing stress on the traits left. Salicylic acid spraying have many traits such as plant height, ear weight, grain yield and positively affect biological.Corn seed irradiation with ultrasonic waves for 4 and 8 minutes, leading to increased growth characteristics, yield, yield components and the quality of the maize.
