Abstract
Faba bean (Vicia faba L.) is one of the main leguminous crops grown in winter season in different soils of Egypt. The aim of this study is to show the effect of applying zinc (Zn) and cobalt (Co) in different methods (foliar and soaking) and rates in increasing broad bean yield and its components. Broad bean seeds were applied with Zn and Co as foliar in two rates for each element in twice time. Application of the two methods and different rates of Zn, Co and the interaction between them showed that all treatments significantly augmented broad bean yield and its components rather than control treatments. The results clearly indicate that the percentage of N, P and K in response to the different methods and rates recorded significant increase in comparison with untreated plants. it could be observed that Fe, Mn, Zn and Co concentrations were increased significantly in broad bean seeds with different methods application and different rates of Zn, Co and their combination as compared with control. Concerning the effect of Co and Zn addition by different methods and rates on macr-micronutrients all cobalt treatments significantly increased nutrients status (except Fe content) and the chemical contents of broad bean seeds when compared with the control treatment. It could be concluded that irrespective of fertilization factor of soaking technique seems to be more efficient than the spraying one for higher yield of faba bean.
