Response of Broad Bean Varieties (Vicia faba L) to Foliaring with different Levels of Zinc in gypsum soil

Abstract

         A field experiment was carried out in Al-Jazira area of ​​Tikrit district - Salah Al-Din governorate to study the effect of spraying with zinc levels on some growth, yield and protein traits of three varieties of broad bean for the winter agricultural season 2020-2021. The experiment was implemented according to a Randomized Complete Block Design R.C.B.D. with the split-plot system, using three varieties of beans that occupied the main factor (local, Syrian and Spanish) and four levels of zinc that occupied the secondary factor (0, 12, 24 and 36 mg.L-1). Added by spraying, the results showed the best Interaction combination treatment with significant superiority between the Spanish variety and the level of zinc 36 mg. L-1 in all studied traits, as it recorded 101.41 cm for plant height, 6.97 branches.plant-1 for the number of branches per plant, 58.25% for chlorophyll, 6.01 seeds.pod-1 for the number of seeds per pod, 2.93 tons.ha-1 for seed yield and 34.15% for protein.
