Other claims from this paper (9)
- Intervention effect Full irrigation produced the highest yields in both seasons.
- Intervention effect Reproductive-stage deficits reduced yield up to 33%.
- Intervention effect Vegetative-stage deficit W3 saved 6% of irrigation water.
- Intervention effect Vegetative-stage deficit W3 caused no significant yield reduction.
- Association Grain yield correlated strongly with actual crop evapotranspiration.
- Association Yield showed diminishing returns at greater irrigation depths.
- Association Higher vapor pressure deficit and wind speed reduced 2018/19 yield and water productivity.
- Association A 9–10% rise in reference evapotranspiration was associated with about 30% lower yield.
- Mechanism Irrigation thresholds were governed jointly by soil hydraulics, irrigation and atmospheric demand.
