Abstract: Guava cv. Khaza is known to have a poor shelf life under ambient storage conditions. But application of post-harvest treatments like Aloe vera gel, Salicylic acid and Benzyladenine as post-harvest treatment can enhance shelf life of the fruits. Hence an attempt had been made to judge the efficacy of the treatments on shelf life and fruit qualities. Aloe vera gel can be used successfully to reduce physiological loss in weight of guava fruits upto 8th day. Benzyl adenine was also successful in retaining ascorbic acid in fruits of guava fruits upto 8th day. The control samples show high Physiological loss in weight. TSS (OB) showed a decrease with storage. The decline in titratable acidity was lesser in T₁ (Aloe vera gel). Ascorbic acid content fall drastically with storage but lesser decline was observed in Aloe vera gel treated fruits. Thus in general it can be concluded that Aloe vera gel (T₁) coating can be considered as the best treatment as it retained high ascorbic acid, titratable acidity, firmness and low PLW during the storage period. Followed by Salicylic acid (T₂) and Benzyl adenine (T₃).
