Abstract

To investigate the influence of pre-harvest application of Gibberellic acid and Borax on fruit retention, yield and quality of Mango (Mangifera indica L.) cv. Dashehari, an experiment was carried out in the garden, Department of Fruit Science, C.S. Azad University of Agriculture and Technology, Kanpur -208002 (U.P.), India, during the year 2022-23. The experiment was laid out in Randomized Block Design (RBD), using nine diverse treatments viz., T1-GA3 20ppm, T2-GA3 40 ppm, T3-Borax (0.2%), T4-Borax (0.4%), T5-GA3 20ppm + Borax (0.2%), T6-GA3 40ppm + Borax (0.2%), T7-GA3 20ppm + Borax (0.4%), T8-GA3 40 ppm + Borax (0.4%), and T9-control i.e., water spray, replicated thrice on 13-year-old, uniform in growth, twenty-seven mango cv. Dashehari plants, spaced at 7x7 m apart. Mango is considered one of the well accepted fruits all over the world due to its luscious taste, captivating flavour and attractive colour. A variety of products can be prepared from both immature green and ripe fruits. The spraying was done at the pea stage of fruit setting using, a very tiny nozzle sprayer. Foliar application of Borax and GA3 plays a crucial part in controlling a variety of physiological phenomena, boosting yield and quality, and increasing plant productivity. The use of boron facilitates the transport of sugar and speeds up fruit bud development. The spraying with a combination of GA3 40ppm + Borax 0.4% (T8) results in maximum number of fruits per panicle (7.14%), minimum fruit drop (85.06%), maximum fruit retention (14.94%), fruit length (11.66%), fruit width (7.14%), weight (243.32g), volume (240.91cc), fruit yield (57.14kg/plant), fruit pulp (72.32%), total soluble solids (22.08°Brix), total sugars (21.08%), ascorbic acid (34.96mg/100ml) with minimum fruit peel (16.64%), stone (11.04%) and titratable acidity (0.40%) under plains of Uttar Pradesh.

Conclusion

Based on the findings of the present investigation, we can conclude that foliar spray of Gibberellic acid and borax on mango fruit crop resulted in significant improvement of flowering and fruiting behaviour of mango fruits which ultimately leads to physical and biochemical attributing parameters of mango. The higher concentration of plant growth regulators (40 ppm GA3) and micronutrients (0.4% Borax) in combination is more effective than the lowest doses of the remaining treatments.
