Abstract: The factor of density (A) and(B) fertilizer was designed on three levels in the experiment. The results indicated that the density and fertilizer had obvious effects on the agronomic characteristics and yield of high-oil maize 115. When the density was 52500 plants/hm2 and the volume of fertilizer delivery was N of 360kg/hm2, P2O5 of 120kg/hm2, K2O of180kg/hm2, the agronomic characteristics was best and the yield was highest (6876.45 kg/hm2).
