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 grain and straw N, P and K uptake 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.
