Effect of Calcium, Boron and Sorbitol on Fruit-Set, Yield and Quality in Mango Cv. Himsagar

Abstract

An investigation was carried out to study the effect of foliar spray of micronutrients, viz, calcium and boron and sorbitol on fruit-set, yield and fruit quality in mango (Mangifera indica L). cv. Himsagar, at Bidhan Chandra Krishi Viswavidyalaya, Regional Research Station, Gayeshpur. The experiment was laid out in Randomized Block Design (RBD), with three replications. Results revealed that boric acid (0.02%) + sorbitol (2.0%) were the most effective for enhancing fruit-set (1.58%), yield (48.51 kg tree-1), fruit weight (165.6 g), TSS (18.59°Brix), total sugars (14.92%) and ascorbic acid content (20.32 mg 100 g-1), while, calcium nitrate (Ca-0.06%) + boric acid (B-0.02%) proved to be the most effective for increasing shelf life in mango cv. Himsagar, at ambient room temperature.
