Effective management of on-farm irrigation for some major crops in Egypt using CROPWAT model

Field experiments were carried out (2013/2014 and 2014/2015 for wheat; 2014 and 2015 for maize) at the two sites of Giza area (Giza governorate, represented to Middle Egypt) and Shandaweel area (Sohag governorate, represented to Upper Egypt). The present study aims to improve water management in on-farm using CropWat model. Fifteen irrigation scheduling scenarios in addition the control treatment have been proposed and studied. The irrigation scheduling criteria included irrigation timing (irrigation at fixed interval days) and application depths (fixed depths “net irrigation”, mm). The Control treatment represented to Farmer application where the irrigation intervals are at a maximum whilst avoiding any crop stress.
