الاحتياجات المائية لمحصول الحنطة القاسية (شام 3)‎ في منطقة الموصل للموسم 2009-2010

Abstract EN

This study aims to determine the gross irrigation water requirement GIWR for durum wheat crop (Sham3) using climate, crop, and soil in Mosul area.

The experiment was carried out in the field of the technical institute of Mosul for the cultivation durum wheat crop cv.Sham3 in season 2009/2010.

The consumptive water use was determined by multiplied the calculated reference crop evapotranspiration using Penman-Monteith equation based on climatological data for Mosul station which considered the nearest to the experiment, by a crop coefficient depended on the growth of stages ( initial, development, mid, and end stage).

The GIWR was 175 mm.season-1 and determined based on the effective rainfall, consumptive water use, change in soil water storage in root zone, and efficiency of irrigation.

Four irrigation treatments were used 100%, 50%, 25% from GIWR, and without irrigation, only rainfall.

The results showed that the crop properties such as the grain yield increases with irrigated in full GIWR and reached to 5.5 t/ha ,While it decreases by 20% with irrigated in 50% from GIWR.
