This paper estimated the irrigation water requirement of Paddy (summer) in Aat Distributary Navsari of Navsari branch canal KLBMC, by using CROPWAT 9.0 and Water Balance Method. The Meteorological and Rainfall data used for the study were considered from year 2005 to 2017. The effective rainfall obtained by CROPWAT 9.0 and Water Balance Method is 0.4 mm and 9.3 mm respectively. Actual seasonal evapotranspiration by CROPWAT 9.0 and Water Balance Method is 710.1 and 683.3 mm respectively .The net irrigation requirement is 1339.3 mm by using CROPWAT 9.0 and 659.857 mm by using Water Balance Method. Irrigation Scheduling using Water balance method can save water use up to 679.443 mm. The Water Balance Method is more effective and efficient than the CROPWAT 9.0 , only because whereas the earlier method used available soil water at time t over the effective root zone depth and remaining available soil water for irrigation scheduling CROPWAT 9.0 used daily soil water available and readily available water for the same purpose.
