Abstract Crop water requirements (CWR) refer to the amount of water required to compensate for evapotranspiration losses from a cropped field during a specified period of time. Crop water requirements are expressed usually in mm/day, mm/month, or mm/season, and they are used for management purposes in estimating irrigation water requirements, irrigation scheduling, and water delivery scheduling.
