Evaluation of Yield and its Components of Durum Wheat (Triticum durum Desf.) Cultivars Grown Under Rain-Fed and Supplementary Irrigation Locations in Nineveh Province

Abstract

A field experiment was carried out in two locations (Talkaif and Fayda) in Nineveh Province during the agricultural season (2021-2022) to evaluate 30 cultivars of durum wheat in terms of yield and its components under two Irrigation patterns (supplementary Irrigation SI and Rain-fed), the results showed that the cultivars differed significantly among themselves, the cultivar Firat -93 was significantly higher than the other cultivars in the two locations of Telkaif and Fayda in the No. of spikes.m−2 and the weight of 1000 grains, as it gave (396.67 spikes.m−2, 48 gm.) and (281.33 spikes.m−2, 39.52gm.), respectively. The cultivars Dor-29, Fada 98, and Sarıbasak was superior in the No. of grains.spike−1 for both locations (42.17, 41.67, 41.33) and (30.17, 29, 29.17) respectively, while the cultivar Acsad-65 excelled in grains yield gm.m−2 for both locations (531.39, 226.76), respectively. The two cultivars Smito and Saribasak excelled in terms of grains yield in Fayda location only, reaching (223.4, 214.78 gm.m−2), respectively, while the two cultivars Smito and Ari achieved significant superiority in biological yield. (943.67, 918.33 gm.m−2). As for the Irrigation pattern, all cultivars grown under the SI pattern achieved significant superiority for all traits and for both locations of the experiment.
