- Association Yield first increased and then decreased as nitrogen rate increased.
- Association Nitrogen use efficiency first increased and then decreased as nitrogen rate increased.
- Intervention effect N6 at 270 kg ha−1 gave the highest nitrogen use efficiency.
- Intervention effect Thirteenth-leaf topdressing promoted spikelet differentiation and large panicle formation.
- Intervention effect Thirteenth-leaf topdressing increased grains per panicle by 2.36–2.20% versus other treatments at the same nitrogen rate.
- Intervention effect N6 increased nitrogen accumulation by 39.27–67.12% from elongating to heading.
- Intervention effect N6 increased nitrogen accumulation by 7.14–62.24% from heading to maturity.
- Intervention effect N6 increased nitrogen apparent efficiency by 3.51–14.68%.
- Intervention effect N6 increased agronomic efficiency by 29.22–58.25%.
- Intervention effect At heading, N6 high-effective leaf area proportion exceeded N4, N5 and N7 by 1.52–7.05%.
- Intervention effect N6 had a slower leaf area decay rate.
- Intervention effect N6 increased dry matter accumulation by 5.85–33.44% from elongating to heading.
- Intervention effect N6 increased dry matter accumulation by 0.42–26.98% from heading to maturity.
- Intervention effect N6 had a 3.8–17.2% yield advantage over other treatments.
- Recommendation The authors recommend basal, tiller and 13th-leaf topdressing at 270 kg ha−1 for high yield and nitrogen efficiency.
