Guava cv. Khaza is known to have a poor shelf life under ambient storage conditions. But application of post-harvest treatments like Aloevera gel, Salicylic acid and Benzyladenine as post-harvest treatment followed by pre-packaging in polyethylene film of different thickness can enhance shelf life of the fruits. Hence an attempt had been made to judge the efficacy of the treatments with their interaction with packaging practices on shelf life and fruit qualities. Aloevera x 50µ LDPE can be used successfully to reduce physiological loss in weight of guava fruits upto 9th day. Benzyl adenine x 50µ LDPE was successful in retaining fruit firmness of guava fruits upto 9th day. Most of the interactions were able to ensure fruit colour (light yellow) upto 9th days of storage. The control samples only show change in colour to yellow irrespective of the packaging used. TSS (OB) showed a decrease with storage. But the rate of decline was lesser in case of Benzyl adenine x 50µ LDPE (6.9 OB) followed by Aloevera gel x 50µ LDPE (6.83 OB). The decline in titratable acidity was lesser in Salicylic acid x 25µ LDPE (0.363). Ascorbic acid content fall drastically with storage but lesser decline was observed in Aloevera x 50µ LDPE (133.01), Aloevera gel x 25µ LDPE (126.59), Benzyl adenine x 25µ LDPE (126.58) and Salicylic acid x Aloevera gel (118.33). Hedonic scores based on organoleptic properties were maximum in T3P1 (5.87) followed by T1P1 (5.73) at 9th day of storage.
