| Abstract: | The results of cultivation test of maize with varieties, density, N-fertilizer and P-fertilizer indicated that density was principal factor on the yield of maize, and varieties had important effect on the grain characters and agronomic characters. For highest yield, varieties, density, N-fertilizer and P-fertilizer of spring maize should be Yedan19, 6?04/hm2, 255 kg/hm2 and 75 kg/hm2 respectively. |
