Das, A.K., Islam, S. and Mondal, M.F. (2007) Studies on post harvest diseases and shelf life of mango. Journal of the Bangladesh Society for Agricultural Science & Technology, 4 (3-4). pp. 185-188.
An experiment was conducted to determine the incidence and severity of diseases and shelf life of mango under different storage conditions. The experiment was conducted in Completely Randomized Design (CRD) with three replications. Two varieties of mango, viz., Fazli and Aswina with or without peducnle and four different postharvest treatments, viz., control, hot water, unperforated polythene bag, KMnO4 in unperforated polythene bag. The postharvest treatments had significant effects on incidence and severity of diseases as all as on the shelf life of mango. The variety Fazli was more susceptible to postharvest disease than Aswina. The highest disease incidence (51.06%) was observed in Fazli where as the lowest (44.22%) disease incidence was found in Aswina. Postharvest diseases were severe at the end of the storage period and the maximum disease incidence (100%) and disease severity (90%) were recorded in untreated fruits whereas, the minimum disease incidence (77.08%) and disease severity (9.77%) were noted in fruits wrapped with unperforated polythene bag with KMnO4. THe postharvest treatments showed highly significant variation on shelf life of mango. The maximum shelf life (15.04) days was observed in Aswina and the minimum (14.12 Days) was noted in Fazli. The results revealed that unperforated polythene bag with KMnO4 caused the longest shelf life (17.58 Days) followed by unperforated polythene bag and hot water treatment while the shortest shelf life (12.00 Days) was recorded in untreated fruits. Similarly, mango with peduncle had longer shelf life (15.12 Days) than that of (14.04 days) without peduncle. Further, mango with peduncle when treated with KMnO4 + unperforated polythene bag appeared to be the best for extending shelf life. The longest (18.66 days) shelf life was recorded in Aswina fruits with peduncle when kept in unperforated ploythene bag containing KMnO4 and the shortest (11.5 days) shelf life was recorded in Fazli without perduncle under control.
