Other claims from this paper (16)
- Intervention effect A second irrigation at flowering increased grain yield in drier seasons compared with one irrigation.
- Intervention effect Two irrigations did not increase grain yield under sufficient pre-sowing moisture in normal precipitation seasons.
- Intervention effect Two irrigations significantly reduced water use efficiency in normal precipitation seasons.
- Intervention effect Two irrigations inhibited root growth into deeper soil layers.
- Intervention effect Two irrigations weakened use of soil water and nitrate nitrogen from deep layers.
- Intervention effect Nitrogen application increased wheat yield compared with no nitrogen.
- Intervention effect Nitrogen application increased wheat water use efficiency compared with no nitrogen.
- Intervention effect Wheat grain yield did not rise further above 240 kg N ha-1.
- Intervention effect Wheat water use efficiency did not rise further above 180 kg N ha-1.
- Intervention effect Nitrogen at 240 kg ha-1 facilitated wheat root growth in deep soil.
- Intervention effect Nitrogen at 240 kg ha-1 facilitated deep soil water and nitrate nitrogen use.
- Intervention effect Nitrogen at 240 kg ha-1 reduced residual nitrate nitrogen.
- Association Grain yield was significantly positively correlated with pre-sowing soil water storage.
- Association Grain yield was significantly positively correlated with pre-sowing nitrate nitrogen accumulation.
- Recommendation The authors recommend 180-240 kg ha-1 nitrogen with two irrigations to reduce yield-loss risk in dry growing seasons.
- Recommendation The authors recommend a single irrigation at jointing under better soil moisture conditions.
