Other claims from this paper (13)
- Intervention effect July 21 transplanting significantly increased rice yield and yield attributes.
- Intervention effect July 21 transplanting significantly increased grain and straw N, P and K uptake.
- Intervention effect August 5 planting reduced grain yield by 12 per cent.
- Intervention effect August 5 planting lost 28 kg grain/ha/day.
- Intervention effect July 6 or 21 transplanting significantly raised AEN and PFPN relative to August 5.
- Observation July 21 planted rice had the lowest nitrogen harvest index.
- Intervention effect Increasing nitrogen significantly raised yield and yield attributes through 180 kg N ha-1.
- Intervention effect At 180 kg ha-1, rice grain yield was 2.20 per cent higher than at 120 kg ha-1.
- Intervention effect At 180 kg ha-1, rice grain yield was 13.30 per cent higher than at 60 kg ha-1.
- Intervention effect At 180 kg ha-1, rice grain yield was 32.78 per cent higher than control.
- Intervention effect Nitrogen above 60 kg N ha-1 significantly reduced agronomic efficiency, partial factor productivity and apparent recovery.
- Intervention effect Increasing nitrogen significantly decreased nitrogen harvest index.
- Intervention effect July 21 transplanting plus 120 kg ha-1 nitrogen maximized net return and benefit to cost ratio.
