Other claims from this paper (9)
- Method / resource Calibrated AquaCrop predicted maize grain and biomass yield with prediction error 4 < Pe < 5 per cent.
- Method / resource Calibrated AquaCrop reached R2 of 0.64 to 0.81 for maize yield.
- Method / resource Upon validation, AquaCrop prediction error for maize yield was between 10 and 6.
- Method / resource Upon validation, AquaCrop R2 for maize yield was between 0.65 and 0.76.
- Method / resource Upon validation, AquaCrop RMSE for maize yield was between 1062 and 1293.
- Method / resource The highest accuracy to predict yield and biomass was at I1 (MAD 20%) rather than I4 (MAD 80%).
- Method / resource The lowest accuracy to predict yield and biomass was at I4 (MAD 80%) rather than I1 (MAD 20%).
- Method / resource AquaCrop simulated aboveground biomass more accurately than grain yield.
- Association AquaCrop could not provide satisfactory results under severe water stress.
