Other claims from this paper (11)
- Observation Performance differed for both crops across water deficit levels.
- Intervention effect T1 and T2 did not cover ETc during critical period and grain filling, lowering yields.
- Intervention effect T3 and T4 yielded more, with significant three-year average differences.
- Observation T3 sometimes failed to cover ETc but soil reserves and precipitation saved irrigation water.
- Method / resource AquaCrop simulated maize yield, biomass and soil moisture well under irrigation.
- Method / resource AquaCrop underestimated yield in T1.
- Method / resource At 0.90 m depth, AquaCrop simulated T1 yield well, especially in the dry year.
- Method / resource The adjusted AquaCrop model predicted yield well across irrigation and precipitation situations.
- Intervention effect Five mm net irrigation gave returns and income similar to 8 mm net.
- Intervention effect Depleting 100% RAW gave higher water productivity but was risky in dry years.
- Recommendation Irrigation strategy can vary with annual climate outlook.
