Other claims from this paper (18)
- Method / resource ORYZA satisfactorily simulated rice biomass and nitrogen uptake across irrigation and fertilizer regimes.
- Association Rice yield varied greatly among years because of climate change and was enhanced by nitrogen rates.
- Observation Nitrogen response curves differed between water regimes.
- Association Agronomic efficiency decreased as nitrogen rates increased from zero.
- Intervention effect One basal nitrogen split produced the lowest rice yield.
- Intervention effect One basal nitrogen split gave high physiological efficiency.
- Intervention effect One basal nitrogen split gave the lowest fertilizer recovery.
- Intervention effect One basal nitrogen split gave the lowest agronomic efficiency.
- Intervention effect Four nitrogen splits produced high nitrogen uptake, agronomic efficiency and fertilizer recovery.
- Intervention effect Four nitrogen splits produced high partial factor productivity.
- Intervention effect Four nitrogen splits produced low physiological efficiency.
- Observation At 150 kg N ha−1 with basal application, AWD water productivity was 1.19 kg m−3.
- Observation At 150 kg N ha−1 with basal application, CF water productivity was 0.82 kg m−3.
- Observation At 225 kg N ha−1, AWD water productivity was 1.50 kg m−3.
- Observation At 225 kg N ha−1, CF water productivity was 1.14 kg m−3.
- Intervention effect AWD generally gave higher water productivity than CF.
- Intervention effect AWD had no rice yield penalty compared with CF.
- Recommendation Appropriate nitrogen splitting could improve water productivity and nitrogen efficiencies and lead to high rice yield.
