Effect of deficit irrigation on productive of durum wheat (Sham 3)

Abstract

Abstract:

This study aims to determine effect on deficit irrigation in many levels compared with full irrigation on productive of local cultivar durum wheat (sham3) in Rural Damascus, by reverence evaporation(ETo) estimated using class-A pan-data with three levels (100%-80%-70%) IW-CPE Irrigation Water (IW) -Cumulative Pan Evaporation (CPE) depended on methods to determent water requirements.

Result showed that   wheat productivity decreased significantly, when water stress was applied by both levels (80%-70%) IW-CPE with the means (5410-4559) kg.h^-1 respectively compared with full irrigation, which was (6579) kg.h^-1. In addition, there is difference between them. Mean of protein present of seeds was 13.5 % with increasing significantly from both levels (100%-80%) IW-CPE respectively (12-12.6)% but there is no significant different between them. This study approves effect of different irrigation levels on durum wheat productive. With an apparently difference in protein percentage at the average level (80%) IW-CPE and significantly when less than that.
