Other claims from this paper (13)
- Method / resource APSIM simulated wheat yield with RMSE 0.83 t ha −1.
- Method / resource APSIM simulated wheat biomass with RMSE 1.40 t ha −1.
- Method / resource APSIM simulated maize yield with RMSE 1.07 t ha −1.
- Method / resource APSIM simulated maize biomass with RMSE 1.70 t ha −1.
- Method / resource Soil water was reasonably predicted with RMSE 24.33 mm.
- Method / resource ET was reasonably predicted with RMSE 1.49 mm d −1.
- Observation Simulated rainfed wheat yield ranged from 0 to 6.1 t ha −1 in double cropping.
- Observation Simulated rainfed maize yield ranged from 0 to 9.7 t ha −1 in double cropping.
- Intervention effect Each additional 60 mm irrigation increased simulated crop yield by 1.2 t ha −1.
- Intervention effect 540 mm irrigation was required to achieve simulated maize yield potential of 8.3 t ha −1.
- Intervention effect With over 180 mm irrigation available, allocating it to both crops produced higher total yield than irrigating wheat alone.
- Intervention effect Switching to a single crop system significantly lowered simulated annual total crop yield.
- Mechanism Single crop yield could increase because more soil moisture was stored.
