Effects of Different Fertilizer Application Levels on Yield and Quality Physiology Index of Shentian No.6

Xuemei Zhong

Abstract

In the 57 000 plant/ha spring sowing condition,the experiment of fertilizer on sweet corn Shentian No.6 were conducted.The results showed that the best fertilization of maximum yield was N 187.5 kg/ha,P2O5 75.0 kg/ha,K2O 97.5 kg/ha,the fresh ear yield of sweet corn was 13 437.0 kg/ha and leaf area index of sweet corn was 2.78,the quality and each physiologic characteristic were in good condition.Over this amount of fertilization could restrain the improvement of fresh ear yield.Sugar content in sweet corn and leaf area index were both down.
