Abstract

The results of the experiment indicated that Hybrid Maize could obtain the highest yields and the best economic performances as K application was 150.0 kg/hm2. The highest yield of Hybrid Maize reached 7065 kg/hm2 and increased by 9.9% than CK. The income was raised about 892 yuan/hm2 and the value cost ratio reached 2.2. The results also showed that potassium content in the soil decreased and cannot keep balance when the K was applicated under 150.0kg/hm2.

Key words
