Study of Quality Traits of Durum Wheat (Triticum durum Desf.) Cultivars Grown Under two Irrigation Patterns, Locations in Nineveh Province.

Abstract

The experiment was conducted at two environmental locations in Nineveh province (Tel Kaif and Fayda) during season 2021-2022, to evaluate 30 cultivars of durum wheat under two patterns of irrigation  (Rain-fed and supplementary) and their effects on the   qualitative traits of flour, for this Aim, field experiments were implemented.
