Yield related interpretations of irrigation uniformity and efficiency measures

Irrigation Science Aims and scope Submit manuscript

Summary

A number of irrigation performance parameters have been used to quantify irrigation uniformity and efficiency. These parameters are usually regarded as performance indices only, without a physically significant interpretation. Common irrigation uniformity and efficiency measures can be related to expected yields from non-uniform irrigation of certain hypothetical crops. Calculation of these measures is equivalent to, or closely related to, calculation of expected yields with non-uniform irrigation for the water-yield functions of Fig. 1. This relationship between performance measures and expected yield lends physical significance to irrigation uniformity measures, and suggests useful generalizations of traditional uniformity and efficiency measures that are directly related to crop yield.
