Abstract : The investigation was carried out with a view to study the retardation of ripening process, to increase the shelf life and to minimize the post harvest losses in mango fruit cv. 'KESAR', under the influence of various plant extract treatments viz., neem leaf extract, bael leaf extract, neem oil and sesame oil; and wrapping material viz., tissue paper and polynet wrapping. Matured freshly harvested mango fruits of uniform size were treated with different treatments as post harvest dips for ten minutes. Then fruits were wrapped with wrapping materials and kept in Corrugated Fiber Board (CFB) boxes at ambient temperature (35±2°C). The fruits treated with different plant extracts and wrapped in different wrapping materials, showed lower and slower rate in physical and chemical changes than control fruits. The fruits treated with neem oil 10 per cent proved to be most effective with respect to longer shelf life, lower physiological loss in weight and higher firmness of fruits. The treatment was also promising for slower increase in TSS, while slower decrease in ascorbic acid and acidity during storage. Among wrapping materials, tissue paper was promising material.
