EFFECT OF SUPPLEMENTAL IRRIGATION ON GROWTH AND VARIETIES FORAGE YIELD OF FIELD PEAS (PISUM SATIVUM L.)

The study is conducted during the winter season of 2020 in two sits: the first in Bashiqa district (Tubazawa village), approximately 15 km east of Mosul city, and the second at the field of College of Agriculture and Forestry - Mosul University, approximately 6 km north of Mosul, to study the impact of supplemental irrigation on the traits of growth and feed yields of four species of peas (Ariare, Alia ire, Helaana, and Kaspe). The trial was applied depending on spilt plots by randomized block design with three replicates. The results show there is a supremacy of Ariare upon Helana and Kaspe in the traits of plant height, wet feed, and several horns and seeds at both study sites respectively, and the trait of dry peas yield at Tubzawa site, a kaspe class has supremacy in the trait of dry peas yields of other species at the Mosul site. The level of supplemental irrigation (T2) exceeded the level of leaves, a number of horns and seeds at the site of Tubzawa, and the fourth irrigation level (T3) has supremacy in the plant height and the source of wet feed at both study sites and% leaves and the yield of dry feed and the number of horns and the number of seeds at the site of Mosul and exceeded the level of irrigation (T2 and T3) in the dry horns in both sites of the study.
