and yield world wide. Review of current trends of water availability
indicated that agricultural activities are approaching a
“water crisis” in several regions, most notably in the Mediterranean
region. The major agricultural use of water is for irrigation, which
is affected by decreased supply. Therefore, improvement in crop
water productivity (WP) in agricultural is of strategic importance.
Both deficit irrigation (DI) and partial root-zone drying (PRD) are
water-saving irrigation strategies
