Biofortification is a global-scale agricultural approach that can improve human nutrition. Agronomic biofortification is viewed as a quick-fix and supplemental approach. Agronomic biofortification, especially foliar application, is highly effective for zinc and iron. A field experiment on agronomic biofortification of zinc and iron micronutrients in mango cv. Kesar was carried out in 2016-2017 at the Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat). The experiment was arranged in a completely randomized design (CRD) with three replications containing 9 treatments. The results show that foliar application of ZnSO4 and FeSO4 (0.5% each) resulted in higher N (48.73 mg/100 g) and K (94.17 mg/100 g) in the pulp and P (0.056%) in the peel of mango. The iron (Fe) and zinc (Zn) contents in pulp and peel were highest in treatment T9 (0.50% FeSO4 + 0.50% ZnSO4), which was on par with those in treatment T8 (0.50% FeSO4 + 0.25% ZnSO4).
