Agronomic biofortification with zinc and iron to enhance nutrient concentrations in mango

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)

Effect of Ferti-Fortification of Iron and Zinc Fertilization on Quality Parameters of Mango Cv. Kesar

The present research was accomplished on mango cv. Kesar to investigate the effect of foliar spray of iron and zinc fertilization on the quality parameter of mango. The experiment was conducted in a completely randomized design and replicated 3 times with 9 treatments. The The significant increase in TSS (19.35 °Brix) and ascorbic acid (36.70 mg/100 g) content were recorded with the foliar application of 0.5% FeSO4 and 0.5% ZnSO4 (T9) resulted in a considerable rise in TSS and ascorbic acid content, which was comparable to treatment T7 (0.25% FeSO4 + 0.50% ZnSO4)
