Other claims from this paper (10)
- Intervention effect Nitrogen additions increased rice yield by 3.7–26.9% at Shayang versus zero N.
- Intervention effect Nitrogen additions increased rice yield by 8.4–22.5% at Wuxue versus zero N.
- Observation Harvest-time effects on grain yield varied with nitrogen application rate.
- Observation Harvest-time effects on nitrogen use efficiency varied with nitrogen application rate.
- Intervention effect At higher nitrogen levels, delayed harvest increased thousand-grain weight.
- Intervention effect At higher nitrogen levels, delayed harvest increased grain filling rate.
- Intervention effect At higher nitrogen levels, delayed harvest increased grain yield.
- Intervention effect At zero or low nitrogen, delayed harvest caused grain abscission.
- Intervention effect At zero or low nitrogen, delayed harvest decreased grain yield.
- Recommendation The authors recommend adjusting harvest timing to nitrogen rate to increase rice yield and nitrogen use efficiency.
