Irrigation scheduling using ICSWAB model

Abstract

The paper presents a simple method of irrigation scheduling using ICSWAB model for dry land crops. The main inputs to this approach are daily precipitation or irrigation amounts and open pan evaporation (US class 'A' pan-mesh covered). The fixed cumulative  evapotranspiration procedure is better than fixed days or fixed percentage soil moisture procedures of irrigation scheduling. Fixed days procedures could be reasonably applied during nonrainy season.
