Effect of Different Levels of Phosphorous Fertilization on Growth, and Yieldcomponenets of some Common Vetch (Vicia Sativa L) Varieties

Four phosphorus fertilizer rates (0, 30, 60, and 90 kg ha-1) were evaluated for the nine common vetches (Vicia sativa) varieties ,Clima, Hanka, Mikaela, Lujiliana, Marrianum, Mery, Beybi, Nigra, Namoi. Experiments was conducted during winter season of 2019-2020 in Sulaimani governorate at Qlyasan locations. The experiment designed Factorial CRBD (Randomized Complete Block Design) with three replications. Means comparison carried out by least significant difference (LSD) a level 5%.Control treatment (no application) results best value plant height, number leaves plant-1, leaf stem ratio 90.106 cm, 104.156, 0.810, respectively.The application 30 ha-1for character 100 seed weight recorded maximum 19.064.While variety 4 produced values 130.083 characters 4.659 branches 93.781 Days to 50% flowering .However 5 gave dry 3.093(g) 5.08(g) respectively.Variety Seed yield reached 6840.425(kg ha-1).The Dry (g) showed highest 7.407for Control application),followed 6 2.031 ratio. days 94.953 6.in which interactions between 7 60 ha-1 no. plant-1 followed 2 149.443 maturaity . pod plant-1with 22.073 7.The no.of Pods plant-1by 7774.053 under ha-1.
