چکیده

Iron is a necessary mineral for plants' biological redox system and an important component of many enzymes. In the present study, effect of iron on morphological, biochemical, and physiological properties of soybeanwere investigated. The experiments were arranged in a completely randomized design with three replicates. Analysis of the data was carried out using SPSS with multiple range Duncan test (P < 0.05)as the statistical tool for comparison of means. The findings suggested that FeSO₄increased seed production, nodule formation andthe number of pods and leaves. However, higher concentrations of FeSO₄reduced nodules and leaf numbers. It was also observed that antioxidant enzymes activity in roots and shoots gradually increased with an increase in FeSO₄ concentration. The iron content in the treated plants increased in proportion to the increase in FeSO₄.
