Studies on effect of foliar application of salicylic acid, azoxystrobin and cycocel on physiological loss in weight and quality traits of onion cv. Arka Kalyan

Abstract

Onion is a commercial vegetable crop, demands storage to meet off season requirement during which the quality traits were lost in addition to this huge post harvest losses interms of physiological loss in weight, sprouting and rotting are noticed. Thus an attempt has been made at College of Horticulture, Bagalkot, to test efficacy of salicylic acid, azoxystrobin and cycocel on physical and quality traits of onion cv. Arka Kalyan. The experiment was laid out in Randomized Complete Block Design, with 12 treatments and 3 replication. The combined application of chemicals viz., salicylic acid @ 2 mM, azoxystrobin @ 0.1%, at 60 and 90 DAT and CCC @ 2500 ppm at 90 DAT resulted in reduced physiological loss in weight (11.62%) and maximum sensory scores. Application salicylic acid (2 mM) reduced respiration rate of stored onion bulbs and improved quality traits like firmness, moisture and dry matter of stored onion bulbs. The combined application of chemicals was effective in reducing the physiological loss in weight and improving the quality traits in onion cv. Arka Kalyan.
