Influence of pre-harvest sprays on physical and physiological parameters of custard apple cv. Balanagar

An experiment was conducted to study the influence of pre-harvest sprays on physical and physiological parameters of custard apple cv. Balanagar was carried out at KRC College of Horticulture, Arabhavi (UHS, Bagalkot) during 2016 and 2017. The treatments comprising of pre-harvest sprays viz., CaCl2, borax, salicylic acid and potassium silicate were applied to the trees at one month before harvesting during both the years. Among the treatments, pre-harvest spray of 0.60 per cent potassium silicate and 2.0 per cent calcium chloride were found to be maximum fruit weight, length, breadth, volume, specific gravity, ripe fruit weight, pulp weight, pulp recovery, shelf life and minimum peel weight, seed weight, PLW and respiration rate when compared other treatments.
