Effect of different combinations of pruning, nutrition and paclobutrazol on fruit quality, shelf life and occurrence of spongy tissue in Alphonso mango

Abstract

Alphonso is the best table variety of mango and has great demand in the global market owing to its keeping quality, aroma, texture and flavour. Due to its inherent physiological disorders like susceptible to spongy tissue disorder we have not been able to achieve the expected export of the fruit. Keeping this in view, experiment was designed to find out suitable remedial measures by using pruning, nutrition 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, Bengaluru. The treatment T4 recorded higher pulp to peel ratio (5.94) and higher pulp to stone ratio (4.68), higher TSS (20.42oB), lower acidity (0.35%) and the highly significant observations like more number of days (15.68) for shelf life and lesser incidence of spongy tissue (6.67%).
