Abstract

This study provides an evaluation of a number of crop yield response functions. The relative sensitivity of each function in application with the same water stress has been assessed. The coefficients for each function were derived from the linear relationships between relative yield and relative evapotranspiration as described by Doorenbos and Kassam (1979), The data showed that the stage-by-stage results are approximately the same using all functions. When using published crop yield coefficients, all functions gave approximately the same results.
