- Observation From sowing to revival, soil water in the 0–100 cm layer fell significantly.
- Observation At that stage, stored water in the 100–200 cm layer did not change.
- Intervention effect Plastic mulch conserved 6.5 mm more soil water than no mulch across N rates.
- Observation At harvest, soil water declined in both 0–100 and 100–200 cm layers.
- Intervention effect Mulched plots used 34.8 mm more water from 0–200 cm than unmulched plots.
- Intervention effect Plastic mulching increased harvested water and yield.
- Intervention effect Under mulch, high N raised biological yield by 22.5% over low N.
- Intervention effect Under mulch, high N raised grain yield by 22.6% over low N.
- Intervention effect At low density, high N increased grain yield by 29.1% over low N.
- Intervention effect At high N and high density, mulch raised biological yield by 39.5%.
- Intervention effect At high N and high density, mulch raised grain yield by 28.9%.
- Observation High N with low density gave the highest biological and grain yields.
- Observation Biological-yield water use efficiency reached 43.7 kgmm-1 ha-1.
- Observation Grain-yield water use efficiency reached 22 kg mm-1 ha-1.
