Other claims from this paper (13)
- Intervention effect Lesser irrigation and nitrogen lowered grain yield, WUE and AEN.
- Intervention effect Lesser irrigation and nitrogen lowered profit.
- Intervention effect Moderate irrigation and nitrogen reduction improved grain yield, WUE and AEN.
- Intervention effect Moderate irrigation and nitrogen reduction improved profit.
- Association Grain yield increase was associated with higher thousand grain weight and kernels per spike.
- Intervention effect Moderate irrigation reduction lowered soil moisture.
- Intervention effect Moderate irrigation reduction improved redistribution of preanthesis dry matter to grain.
- Intervention effect Moderate nitrogen reduction led to a more reasonable wheat nitrogen nutrition index.
- Intervention effect Moderate nitrogen reduction improved flag leaf area and chlorophyll relative content at anthesis.
- Mechanism The improved nitrogen status played a positive role in biomass accumulation and redistribution.
- Mechanism The improved nitrogen status played a positive role in yield structure optimization.
- Recommendation The authors identify 285 kg ha −1 N and 4170 m 3 ha −1 I as optimal for TR6S.
- Recommendation The authors suggest applying this strategy to other arid and semi-arid regions.
