Abstract
Effect of planting density,cultivar and amount of nitrogen,phosphorus,potassium fertilizer on yield of three corn varieties,xinzhongyu 801,Qiandan 100 and Jinxiang 369,were investigated by split-plot designs and L9( 34) orthogonal experimental design. The results showed that the best planting density was3699 /667 m2,by which the yield of 652 kg/667 m2was gained. The highest yield( 703. 1 kg /667 m2) of Qiandan100 was obtained from the planting density of 3699 plants /667 m2combined with application of N 18kg /667 m2P2O512 kg /667 m2,K2O 10 kg /667 m2. With the exception of K2O amount,no significance differences in yield were observed from other fertilizers.
