Abstract

Two field experiments were performed in 2010-2011 and 2011-2012 winter seasons at two sites  at Agricultural Experimental Station (AES) in Giza and at Wadi El-Natron Experimental Station (WES), Faculty of Agriculture, Cairo University for studying the effect  of three water deficit levels [10%, 20% and 30% (ETc) Crop Evapotranspiration] at different growth stages of wheat (vegetative, flowering, repining,  mature stage and all growth stages combined),  crop response factor to deficit irrigation (Ky) and  impact of deficit on water productivity. The reduction percentage of seed-wheat yield was 13.6, 10.2, 7.2, 3.7 and 3.6% when deficit irrigation was applied in (AES) at all growth stages combined, flowering, repining, vegetative and mature stage respectively. Whereas, the reduction percentage was 14.1, 12.2, 8.2, 12.2 and 5.7% for the same treatments in (WES). The yield response factor (Ky) values increased by increasing the deficit level. Crop response to deficit irrigation (ky) according to the different stressed-growth stages is found in the following order flowering> repining> mature> overall season> vegetative in both sits under studied conditions.
