Abstract: Effects of PAA ,PAM and additional water amount on corn yield in arid area were studied through 311-A application of optimal fitting saturated regressive design. The results showed that the effect of single factors on corn yield was: PAM〉PAA〉 additional water amount;the effect of interaction two-factor on corn yield was: PAA+PAM〉PAM+additional water amount〉PAA+ additional water amount.The results after simulated optimization showed the optimal combination was that the PAA was 51kg/ hm^2,PAM was 36kg/hm^2 and additional water amount was 0.302L/point,the yield was 7845.45kg/hm^2.
