Abstract:
The present investigation on “Effect of preharvest application of different chemicals and plant growth regulators on physical parameters and shelf life of mango (Mangifera indica L.) var. Amrapali” was carried out during summer season of the year 2016 at Anand. The plants of mango were preharvest sprayed with CaCl2 1%, CaCl2 2%, Ca(NO3)2 1%, Ca(NO3)2 2%, KNO3 1%, KNO3 2%, GA3 25 mg/l, GA3 50 mg/l, ethrel 0.1 ml/l and ethrel 0.2 ml/l. There were eleven treatment embedded in Completely Randomized Design replicated thrice. Thirty three uniform size tree of mango were selected. Fresh and mature fruits were harvested from trees which was preharvest sprayed with different chemicals and plant growth regulators and stored under ambient storage condition. Among all the treatment, GA3 25 mg/l treatment recorded significantly highest fruit length, fruit diameter and fruit volume at harvest and at fully ripening stage whereas, same treatment also obtained the significantly maximum fruit weight consistently at harvest and every day up to 16th day under ambient storage condition. The preharvest application of CaCl2 2% recorded significantly minimum physiological loss in weight consistently during 2nd day and every day up to 16th day whereas, same treatment recorded significantly highest shelf life of fruit. However, preharvest treated fruits with CaCl2 2% also recorded significantly maximum marketable fruits (%) and minimum spoilage (%) at 13th day, 14th day, 15th day and 16th day under ambient storage condition.
