Influence of salicylic acid on the quality and storage in onion cv. (Akola safed)

Abstract

An experiment entitled “Influence of salicylic acid on the growth, yield and quality in onion Cv. (Akola safed)” was carried out during rabi season of academic year 2016-2017, at Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment was conducted in Factorial Randomized Block Design, with three replications and 13 treatment combinations with control treatment. There were two factors, main factor being stages of application with 3 levels viz. 30 DAT, 60 DAT, 30 and 60 DAT and another sub factor was concentration of salicylic acid with 4 levels viz. 50, 100, 150, 200 mg l-1. The results of present investigation indicated that, polar diameter (cm), equatorial diameter (cm), TSS (0Brix), ascorbic acid content (mg 100-1 g) in onion bulbs were recorded maximum, wherein the treatment combination consisting of two applications of salicylic acid at 30 and 60 DAT along with salicylic acid @ 100 mg l-1 (A3C2). As regards to the influence of treatment combination on storage parameters viz., physiological loss in weight, sprouting and rottening loss were concerned, they depicted numerically minimum values in the treatment combination consisting of two applications of salicylic acid at 30 and 60 DAT with salicylic acid @ 100 mg l-1 (A3C2).
