e1“Maize yield was not affected by mild water stress over 2 years”
e3“Pot experiments were conducted in 2014 and 2015 with a mobile rain shelter to achieve conditions of no, mild or severe water stress”
e6“Due to the morphological plasticity in root growth and the increase in root ∕ shoot ratio, WU under water stress was decreased”

- Intervention effect Mild water stress did not affect maize yield over 2 years.
- Intervention effect Severe water stress reduced maize yield by 56 %.
- Intervention effect Water stress at both levels decreased maize root biomass slightly.
- Intervention effect Water stress at both levels decreased maize shoot biomass substantially.
- Intervention effect Mild water stress decreased maize root length.
- Intervention effect Mild water stress increased maize root diameter.
- Intervention effect Mild water stress had no effect on maize root surface area.
- Intervention effect Water stress increased the root to shoot ratio of maize.
- Intervention effect Water stress increased water use efficiency for both above-ground dry matter and grain yield in maize.
- Recommendation The authors recommend that an irrigation system may not be economically and ecologically necessary for maize in this region.
