Abstract: | Objective] To study the effects of sowing date and quantity of applied nitrogen on the yield and agronomic characters of maize Junda 001 planted in farmland with medium fertility.Method] The effects of various quantities of applied nitrogen (225, 375, 525, and 675 kg/hm2) and sowing dates (June 2, 10, and 18) on the yield and agronomic characters of maize Junda 001 were analyzed.Result] When the planting density of maize Junda 001 was 67 500 plants/hm2 , the optimal quantity of applied nitrogen was 525 kg/hm2 , and the optimal sowing date was June 2. Conclusion] The research can provide scientific references for the high and stable yield of maize Junda 001 based on the optimal sowing date and quantity of applied nitrogen. |
