- Intervention effect Rice grain yield rose as nitrogen application increased.
- Intervention effect Schedule B increased rice grain yield relative to schedule A.
- Intervention effect Schedule B increased rice spikelets per panicle relative to schedule A.
- Intervention effect Schedule B increased rice percentage of ripened grain relative to schedule A.
- Intervention effect Schedule B increased rice 1 000-grain weight relative to schedule A.
- Observation Soil residual nitrogen fertilizer ranged from 12.40% at N240A to 16.61% at N150B.
- Observation Rice absorbed basal fertilizer nitrogen at panicle initiation.

- Observation Rice absorbed 65.6-92.5% of topdressing fertilizer nitrogen at heading.
- Recommendation The authors recommend schedule B at 240 kg N ha−1 as most profitable among tested treatments.
