Abstract: To investigate the balanced applying NPK fertilizer on maize under sprinkling irrigation condition, the three years field experiments were carried out. The results showed that the maize yield was increased remarkble by applying fertilizer, N〉P〉K. The best economy fertilizer rate N-P2O5-K2O at 15.2-6.4-4.9kg/667m2for maize. The nutrient use efficiency of N,P2O5, K2O was 36.3%, 18.6% and 49.9% respectively. It was confirmed that was to produce 100 kg corn seed needed to absorb the N, PzO5 and K20 were 2.08 kg,0.69 kg and 0.69kg.
