| Abstract: | The effect of planting density and nitrogen application rate on the yield and agronomic characters of a new corn variety Zhengdan 136 was studied in the field.The results showed that there was significant difference in yield among different planting density and nitrogen application rate treatments.Comprehensibly considering the yield and economic benefit,the optimum treatment combination was planting density 75000 plants/hm2,nitrogen application rate 450 kg/hm2 urea. |
