The effect of pre harvest spraying of calcium chloride (CaCl2) and calcium nitrate (Ca NO3) @ 0.5 and 1% on shelf life and quality attributes of mango cvs Dashehari and Amrapali was investigated. Pre harvest spray was carried out on fully grown mango trees prior to one month of harvesting following second subsequent spray, 15 days after of first one. Full ripe fruits of both the cultivars were packed in brown papers bags after washing and surface air drying and stored under ambient condition (36 ± 20C at 75 ± 3% RH). Cumulative physiological loss in weight, spoilage duration, shelf life and the chemical changes viz. total soluble solids, acidity, total sugars and phenols associated with ripening were monitored. Double sprays of Ca NO3) 1%, showed an extended shelf-life of 7 and 7.4 days in Dashehari and Amrapalli, respectively in comparison to 5 days in control with maximum organoleptic score. Results indicated that different pre harvest spraying of calcium compounds were significantly enhanced the fruit quality and shelf life of both the mango cultivars compared to control.
