- Intervention effect Early and normal sowing did not differ significantly in lodging resistance, grain yield, or NUE.
- Intervention effect Late sowing increased lodging resistance by 53.6% versus early sowing.
- Intervention effect Late sowing increased lodging resistance by 49.6% versus normal sowing.
- Mechanism Reduced culm height at the center of gravity contributed to improved lodging resistance.
- Mechanism Greater tensile strength of the base internode contributed to lodging resistance.
- Intervention effect Late sowing maintained grain yield, kernel weight, and kernels per square meter versus earlier sowing.
- Intervention effect Late sowing reduced nitrogen uptake efficiency by 11.0% versus early sowing.
- Mechanism Reduced root length density and pre-anthesis dry matter explained lower UPE.
- Intervention effect Late sowing raised UTE by 12.9% versus early sowing.
- Intervention effect Late sowing raised UTE by 11.2% versus normal sowing.
- Mechanism Reduced grain nitrogen concentration explained increased UTE.
- Mechanism Opposing UTE and UPE responses yielded equal NUE across sowing dates.
