Abstract
This study evaluated the effects of various foliar nutrient treatments on the physical biochemical characteristics and shelf life of Amprali mango fruit. Treatments involving combinations of calcium chloride, borax, and zinc sulfate significantly enhanced pulp weight, fruit weight, pulp percentage, total sugar concentration, total soluble solids (TSS), and the TSS: titratable acidity (TA) ratio compared to the control. The greatest improvements were observed in treatment T5 (Calcium chloride 3.0% + Borax 0.5% + Zinc sulfate 0.3%). Additionally, all treatments reduced peel weight, stone weight, acidity, and physiological weight loss during storage, with T5 showing the most pronounced effects in maintaining fruit firmness and reducing the weight loss. These results suggest that the foliar application of these nutrients promotes fruit quality by enhancing carbohydrate accumulation, accelerating starch-to-sugar conversion, and delaying senescence, thereby improving the yield and postharvest fruit attributes of Amprali mangoes.
