Abstract

Selection of crop production models for use in economicevaluation and optimization of irrigation systems is limitedby the complex nature of these models and the availability ofmodel parameters. Therefore there is need for simplerestimation models, such as the Doorenbos and Kassam's modeland Jensen's model. In this study a function for transformingthe readily available yield response factors of Doorenbos andKassam's model to the sensitivity index of Jensen model isderived. The derived function can be used to estimate with theJensen's model, the effect of water stress during particularperiods on relative yield.
