Calibration and Evaluation of the FAO AquaCrop Model for Canola (Brassica napus) under Varied Moistube Irrigation Regimes

The AquaCrop model was calibrated and validated for canola (Brassica napus) under Moistube irrigation (MTI) various water regimes [(i) 100%, (ii) 75%, (iii) 55% of crop requirement (ETc)] over two seasons, 2019 2020. normalised root mean square (nRMSE), Model Efficiency (EF), R2, the Willmot’s index agreement (d) statistics were used to evaluate model’s efficiency in simulating biomass (B), canopy cover (CC), yield (Y), harvest (HI). calibration results indicated simulated with accuracy CC (under 100% ETcR2 = 0.99, EF 0.92, nRMSE 6.4%, d 0.98) 75% ETc (R2 10.3%, 0.98). well validation 0.97, 0.93, 22.5%, 0.84, 0.45, 59.2%, 0.86) regimes. Final simulations reasonably good ETc, > 0.90, 0.65). study showed usefulness assessing response full deficit scenarios MTI.
