Other claims from this paper (11)
- Observation Winter wheat grain yield exceeded 5000 kg ha −1 in most seasons under minimum irrigation.
- Observation Maize grain yield exceeded 6000 kg ha −1 in most seasons under minimum irrigation.
- Intervention effect Minimum irrigation lowered average maize yield by 13% versus full irrigation.
- Intervention effect Minimum irrigation raised winter wheat water use efficiency by 15% versus full irrigation.
- Intervention effect Minimum irrigation raised maize water use efficiency by 10% versus full irrigation.
- Intervention effect Winter wheat seasonal evapotranspiration was 335 mm under minimum irrigation versus 447 mm under full irrigation.
- Intervention effect Maize seasonal evapotranspiration was 319 mm under minimum irrigation versus 403 mm under full irrigation.
- Intervention effect Minimum irrigation required half the annual irrigation of full irrigation.
- Association Yield reduction under minimum irrigation was negatively related to seasonal rainfall.
- Mechanism The authors attributed minimum irrigation success to deeper wheat roots accessing moisture below maize roots.
- Recommendation The authors concluded minimum irrigation could support groundwater sustainability.
