Zn Increased Flowering and Pod Setting in Faba Beans and its Interaction with Fe in Relation to Their Contents in Different Plant Parts

M.F. El-Masri, A. Amberger, Mohamed M. El-Fouly and A.I. Rezk    

Abstract: A pot experiment was conducted under controlled conditions to study the effect of spraying Zn, Fe and their interactions on pod setting in faba beans. Fe and Zn concentrations were determined in leaves, stems and pods. Faba bean var. Giza 3 was used. Zn treatment increased the number of flowers and pods and percentage of pod setting. Fe showed adverse effects. Zn concentration in all organs was increased by spraying Zn, while it was not affected by spraying Fe. Fe spraying led to increases the Fe content in leaves and stems, while Fe content in pods was decreased. Spraying Zn caused Fe decreases in leaves and pods. Treatments which increased flowering and pod setting showed lower Fe/Zn ratios than the control and vice versa.
