Effect of Different Planting Density and Nitrogen Level on Yield of Shundan 7, a New Hybrid Maize Variety with a Big Ear
The effects of different planting density and nitrogen level on yield, dry matter accumulation, leaf area coefficient and grains per ear of Shundan 7, a new hybrid maize variety with a big ear, were studied by using two-factor split plot design to provide the scientific basis for high yield of Shundan 7. The results showed that the yield of Shundan 7 could reach 745. 4 kg/667m2 with nitrogen fertilizing amount of 25kg/667m2 nitrogen fertilizer and planting density of 3400 plants/667m2.
