Effect of chemicals, PGRs and pruning on flowering and yield in mango under high density planting

Abstract

Investigations were conducted on canopy management in mango (Mangifera indica L) cv Alphonso using chemicals, different growth regulators and pruning methods under high density planting during the year 2015–2016. In the present study emphasis was given mainly to understand the physiological basis for canopy management, flowering and yield. The treatments were evaluated in terms of changes in flowering characters, yield and yield parameters and fruit quality characters. Paclobutrazol (2.5 ml/mof canopy diameter)-received trees were the shortest at pre-flowering stage (Dec 2015) followed by chlormequat chloride triple spray 6, 000 ppm. Paclobutrazol-treated trees recorded the highest fruit set, number of fruits and yield followed by chlormequat chloride triple spray. The yield was almost double as compared to control.
