Abstract: Freshly harvested and uniformly ripe mango cultivar of kishanbhog was collected from the experimental mango research garden of BCSIR Laboratories, Rajshahi, Bangladesh during June - July, 2011 and 2012. The application of plant hormone (IAA, NAA and 2, 4-D) at various concentration (10, 20 and 30 ppm) for the extension of storage life (i. e. shelf life), reduction of postharvest weight loss and quality characteristics of mango cultivar of kishanbhog was studied. The storage life of treated mangoes was prolonged 26.67 % as compared to that from control one and the hormone treatments with 10 and 30 ppm IAA, 10 ppm NAA and 30 ppm 2, 4-D concentrations were found to be more effective in prolonging 4 days of storage life of this cultivar. But at the last edible stage the weight loss of hormone treated mangoes with NAA 30 ppm concentration was the lowest (16.01 %) as compared to that of control one (22.65). The nutritional value of mango was also affected remarkably after treatment with plant hormone. The quality of hormone treated mangoes might be superior in terms of vitamin C, total soluble solids, total sugar, reducing sugar, non reducing sugar content of its pulp which were higher than those of control one. At the last edible stage chemical analysis of hormone treated mango pulp showed the increased amount of total sugar (25.49 %), reducing sugar (25.31 %), non-reducing sugar (22.49 %), total soluble solids (24.22 %) and vitamin C (23.12 %) while the amount of titrable acidity (18.76 %) was decreased as compared to that from control mango.
