Other claims from this paper (10)
- Method / resource The calibrated CERES-Wheat model simulated winter wheat above-ground biomass, grain yield and evapotranspiration accurately across irrigation treatments.
- Intervention effect Simulated highest winter wheat yield came from irrigation at jointing (T9) in normal and dry rainfall years.
- Intervention effect Simulated highest winter wheat yield came from irrigation at double ridge (T8) in wet years.
- Intervention effect A single simulated irrigation at jointing gave 88% of the yield of a double irrigation in wet years.
- Intervention effect A single simulated irrigation at jointing gave 86% of the yield of a double irrigation in normal years.
- Intervention effect A single simulated irrigation at jointing gave 91% of the yield of a double irrigation in dry years.
- Intervention effect A single irrigation at jointing or double ridge gave higher winter wheat water use efficiency, because it obtained higher evapotranspiration.
- Intervention effect Limited irrigation was more profitable than full irrigation when the cost of water was included, under assumed future water costs.
- Recommendation A subsidy will likely be needed to compensate farmers for yield reductions due to water savings.
- Recommendation Limiting irrigation to a single irrigation at jointing would minimize the impact on farmer net return.
