Abstract

In order to evaluate the performance of three Cropping Models: AquaCrop, Wofost, and CropSyst, for simulating rapeseed yield, experimental data collected from Qazvin research station during two years (2010-2012) were used. Treatments were consisted of 12 Deficit Irrigation Scenarios (T1 to T12) and full irrigation (FI) during crop season. Results showed that all three copping models were moderately sensitive with the respect to change the input parameters. AquaCrop was only highly sensitive to alteration of the transpiration coefficient values. The average differences between measured and simulated grain yield using AquaqCrop, Wofost, and Cropsyst were 10. 2%, 12. 1%, and 12. 6%, respectively. The RMSE values for grain yield simulation using AquaCrop, Wofost, and CropSyst were 0. 216, 0. 286, and 0. 332 ton. ha-1, respectively. RMSE values for Biomass using abovementioned models were 0. 223, 0. 418, and 0. 446 ton. ha-1, respectively. NRMSE values for abovementioned models were 0. 04, 0. 09, and 0. 09, respectively. Values for EF were also revealed that AquaCrop had a better efficiency compared to other models. Regarding the results, it seems that AquaCrop is an appropriate Cropping Model to simulate rapeseed yield and Biomass.
