The relationship between crop coefficient =  and time of season, which varies according to crop time of season (days or weeks after planting) at different stages [7]: crop coefficient initial (20% of seasonal time from A to B); crop coefficient development (50% of seasonal time from B to C); crop coefficient mid-season (70% of seasonal time from C to D), and crop coefficient late-season (100% of seasonal time from D to E).
