Present investigation was undertaken to study the effect of various postharvest treatments on extension of shelf life of Kesar mango fruit. For this purpose, the mango fruits were harvested at proper stage of maturity and subjected to various postharvest dip treatments such as calcium chloride (2 and 4 percent), waxing (6 percent) and fungicides viz. Bavistin (0.1 percent) and Captan (0.2 percent) either alone or in combination. The mango fruits were then packed in corrugated fibre board box and then stored in three storage environments viz., at room temperature (28.12 to 36.18 deg C temp and 46.18 to 71.25 percent RH), in cool chamber (21.47 to 27.10 deg C temp and 91 to 95 percent RH) and cool store (10 deg C temp and 90 to 95 percent RH). It was found that the shelf life of mango fruits could be extended upto 65 days when treated with a combination of wax (6 percent)+CaCl2 (2 percent)+Bavistin (0.1 percent) and stored in cool store, upto 35 days when stored in cool chamber and upto 24 days when stored at room temperature. On the contrary, the shelf life of untreated fruit was found to be hardly 18 days at room temperature. It was also observed that this treatment recorded lower physiological loss in weight and high organoleptic score when stored in cool store and cool chamber as compared to room temperature storage. The untreated (control) fruits were found to have infected with Colletotrichum gloeosporioides, Diplodia natalensis and Rhizopus sp.
