Effect of Combination of Different Levels of Pruning, Nutrition and Paclobutrazol on Yield and Economics of Mango (Mangifera indica L.) cv. Alphonso

Alphonso is the best table variety of mango produced in India and has great demand in the global market owing to its keeping quality, aroma, texture and flavour. Due to its inherent physiological disorders, we have not been able to achieve the expected production. Keeping this in view, experiment was designed to find out suitable remedial measures to step up the production by using pruning, INM and plant growth regulators. Field investigation was conducted for two consecutive years (2017-18 and 2018-19) in the established mango orchard on 7 years old Alphonso mango trees and maintained at 5 X 5 m spacing at Regional Horticultural Research and Extension Centre, UHS campus, GKVK, Bengaluru, to investigate the effects of pruning, INM and PBZ on regulating yield. Higher number of fruits per panicle (2.52), less number of days to maturity (108.13), more number of fruits per tree (148.33), highest yield per tree (27.58 kg/tree) and highest benefit cost ratio (3.01) were recorded in trees pruned at 10cm length along with soil drenching of PBZ @ 0.75g a.i./ m canopy diameter, application of 75% RDF, AMC and mango special spray.
