Partitioning evapotranspiration, yield prediction and economic returns of maize under various irrigation management strategies

Several maize field experiments, including deficit and full irrigation, were used to assess irrigation impacts on yields. The SIMDualKc water balance model was first calibrated and validated to obtain the basal crop coefficients (Kcb) and the depletion fractions for no stress (p) relative to all crop growth stages. The values 0.15, 1.15, 0.30 were obtained for, respectively, the Kcb ini, Kcb mid and Kcb end, as well as p = 0.50. The SIMDualKc...
