Climacteric fruits (banana, apple, pear, avocado, garden egg and mango) are actually eaten when ripen; but garden egg is not palatable when ripens and decreases demand. Influence of packaging material and rates of potassium permanganate (KMnO4) on postharvest ripening of garden egg was evaluated to access the interactive effect of KMnO4 and packaging material in delaying ripening. Two packaging materials; polythene and jute bags, KMnO4 at 0g, 3g, 6g and 9g were used. The experiment was a 2 x 4 factorial laid in completely randomized design (CRD) with three replications. Eight treatment combinations were randomly distributed. Fruits were stored for seven days and were observed every 2 days. Result revealed that packaging material influenced postharvest ripening of garden egg with polythene bag reducing the intensity of ripening and significantly reduced shrinkage. Similarly, KMnO4 at (3g and 9g) significantly delayed ripening intensity at 4 and 6 days of storage.
