Abstract:

To investigate the optimal way of corn planting, a split-plot design was adopted in this study. In order to study plant arrangement, plant density and N fertilizer levels on the yield of maize and agronomic traits. The results showed that: among three factors, the plant arrangement and the N fertilizer was significant impact on the yield. But it was no significant different for yield in three kinds of densities. The most optimum treatment was flat planting, 67500 plants per hm2, 112.5 kg/hm2 N fertilizer. The plant arrangement reached significant level to leaf area of three ear-leaves and the plant height, and not reached significant level to the largest of leaf area index and stem diameter. The plant density was reached significant level to the largest of leaf area index, leaf area of three ear-leaves and stem diameter, and not reached significant level to the plant height. With and without application of N fertilizer, the largest of leaf area index, three ear-leaves, stem diameter and the plant height was reached significant level.
