Assessing potato transpiration, yield and water productivity under various water regimes and planting dates using the FAO dual K c approach

Two years of experimental field data on potato (var. Spunta) were used to calibrate and validate the SIMDualKc model. This model adopts the FAO dual Kc approach that provides the partition of crop evapotranspiration into crop transpiration and soil evaporation. Results of model calibration show a good agreement between soil water observations and predictions, with low errors of estimate – RMSE <3.7% of the mean observed soil water – and high...
