Background and objective: This paper is the second of a two-part series, with the first part describing the IMC-Model, an interactive Irrigation Management model for growing Crops that follows the two Kc approaches (dual-Kc and Single-Kc) for computing the actual ETc and then irrigation management parameters. Materials and Methods: The IMC-Model was validated by carrying out field experiments for two growing summer seasons of 2015 and 2016, respectively, in sandy soil at the National Research Centre (NRC) farm, El-Nubaria, Beheira, Egypt. The validated experiment included the following treatments: a) three approaches for computing ETc (single-Kc, dual-Kc, and control), b) two irrigation systems (SDI and SSDI), and c) two oilseed crops (peanut and sesame). Results: Results of the investigation indicated that the IMC-Model is a proper solution for providing appropriate information for irrigation management. In addition, the results revealed that the seasonal cumulative ETc computed by dual-Kc approach overestimated that estimated by single-Kc under SDI by 13.20 % for peanut and 21.90 % for sesame. However under SSDI, the dual-Kc overestimated the single-Kc by 4.42 % for peanut and 17.64 % for sesame. Maximum yield for peanut (2.23 ton fed-1) and sesame (0.66 ton fed-1) were obtained by the dual-kc under SSDI. Optimal water productivity for peanut (0.66 Kg m-3) and sesame (0.23 Kg m-3) were obtained by dual-kc under SSDI.
