Intervention effect High planting density produced more tillers but a low panicle rate.
Intervention effect High planting density produced a low panicle rate.
Intervention effect Low planting density produced fewer tillers.
Intervention effect Low planting density produced a high panicle rate.
Association Nitrogen rate was the major factor influencing Edamai 507 yield.
Intervention effect A density of 2.1×105 plants with 165kg N per hectare produced the highest yield, 5 156.87 kg.
Association Planting density and nitrogen rate were the major factors for effective panicles.
Association Planting density was the major factor for grains per ear and 1000-grain weight.
Intervention effect High density with high nitrogen raised plant height.
Intervention effect High density with high nitrogen increased lodging risk.
Intervention effect Ear length and small panicles per ear might increase under low density and high fertilizer.
Association Effective tiller was the major factor influencing yield.
Recommendation High yield strategy should raise tiller number, ensure panicle rate, and grain filling.
