Effective Management of On - Farm Irrigation for some Major Crops in Egypt using CropWat model
Eight field trials performed for main crops (wheat and maize) during successive two winter and summer seasons 2013- 2015 in two agro-climatic zones in Egypt namely, Giza (Middle Egypt) and Shandaweel (Upper Egypt). The present study aims at improving water management in on-farm using CropWat model. Irrigation scheduling scenarios (15 treatments) in addition the control treatment have been studied. The irrigation scheduling criteria included irrigation timing (irrigation at fixed interval days) and application depths (fixed depths, mm). The control treatment define “optimal” irrigation where the irrigation intervals are at a maximum whilst avoiding any crop stress.
