Effects of different fertilizations and planting densities on yield and quality of high-oil maize variety115

Considering of economical output and commodity in production of highoil maize, fertilization and planting density in different levels were tested in culture of the maize variety 115. The results showed that while the planting density was 52500/hm 2, and the fertilization was N 360kg/hm 2, P 2O 5120kg/hm 2 and K 2O 180 kg/hm 2, the comprehensive trait of the variety, including the grain yield, the percentage of oil content, the protein content and the aminoacid content was the highest; and the starch content was quite low, which is adapted to the planting density and fertilization level at the local condition.
