Other claims from this paper (13)
- Intervention effect Adequate water and nitrogen supply enhanced cotton growth.
- Intervention effect Moderate nitrogen application partly offset yield losses from water deficit.
- Intervention effect Excessive water and nitrogen inputs reduced water use efficiency.
- Intervention effect Excessive water and nitrogen inputs reduced nitrogen partial factor productivity.
- Association Irrigation quota and nitrogen application rate had a synergistic effect on nitrogen partial factor productivity.
- Intervention effect A 10% irrigation reduction under conventional nitrogen significantly improved cotton water use efficiency.
- Association Irrigation markedly regulated nitrogen partial factor productivity under low nitrogen.
- Intervention effect W1N1 enhanced cotton growth traits.
- Intervention effect Ten percent less irrigation under conventional nitrogen boosted WUE by 1.29–1.77%.
- Intervention effect Under low nitrogen, W3 maximized nitrogen partial factor productivity.
- Intervention effect Irrigation of 400–444 mm and nitrogen of 387–440 kg ha−1 sustained stable yield.
- Method / resource PCA, entropy-weighted TOPSIS and grey analysis ranked W3N1/W3N2 optimal for resource efficiency.
- Recommendation The authors recommend 400–444 mm irrigation and 387–440 kg ha−1 nitrogen for Northern Xinjiang cotton.
