Abstract:
We investigated the effect of foliar applications of micro-nutrients, boric acid (H3BO3) and zinc sulphate (ZnSO4), on the quality characteristics of 'Langra' mango fruit. The foliar treatment with 1% H3BO3 + 1.2% ZnSO4 gave the highest total soluble solids (TSS) in the fruit (18.5%) followed by the foliar treatment of 0.8% boric acid (H3BO3) with which had a TSS of 18.3% while the untreated control was significantly lower at a TSS of 16.5%. The maximum amount of vitamin-C (154.3 mg 100 g-1) was also with the foliar treatment of 1% H3BO3 + 1.2% ZnSO4 while the untreated control had 94.7 mg 100 g-1. Maximum total sugars (51.1%) were with the foliar treatment of 1% ZnSO4 while the untreated control had 45.0%. Maximum reducing sugar content was with the treatment of 0.8% boric acid (H3BO3).
