Abstract
The results of this study showed that the effect of different application amounts of nitrogen,phosphorus and potassium on the yield components of high quality maize varieties was different.For Tongyou 1,the yield components were optimal when 195 kg of N,75 kg of P2O5 and 75 kg of K2O were applied per hectare.For Zhengdan 21,the yield components were optimal when 195 kg of N,105 kg of P2O5 and 120 kg of K2O were applied per hectare.
