The research was arranged in a randomized complete block design with four treatments: control, Fe, Zn, and Fe+Zn. The treatments were applied by foliar spraying during the vegetative growth stage. In the applications, 1.5 kg/da of iron sulfate (FeSO₄•7H₂O) and 3 kg/da of zinc sulfate (ZnSO₄•7H₂O) fertilizers were used. The treatments were evaluated based on parameters such as plant height, number of branches per plant, number of pods per plant, first pod height, pod length, number of seeds per pod, first branch height, 100-seed weight, 1000-seed weight, yield per plot, and yield per decare, as well as quality traits such as protein (%), ash (%), and oil content (%).The findings indicated that Fe and Zn applications significantly affected certain agronomic traits depending on the year, including plant height (p KW - Soybean KW - foliar fertilization KW - iron KW - zinc KW - micronutrients KW - yield N2 - This study was conducted over a period of two years to determine the effects of foliar-applied iron (Fe) and zinc (Zn) on the agronomic characteristics of soybean (Glycine max L.).
