The research-study was conducted on effect of Aloe vera gel coating on the post harvest performance of guava (Psidium guajava L.) fruit at Horticulture Department, The University of Agriculture, Peshawar. The research was counducted in completely randomized design (CRD) replicated three times. Aloe vera gel coating, guava cultivars and storage days were considered as three factors for the study. Experimental outcome revealed that coating of gel of Aloe vera at 15% have significant effect on post harvest quality of guava fruit on cultivar Safeda Allahabadi. Results presented that high appearance score (8.32), high taste score (8.30), greatest fruit firmness (3.43 kg cm-2), high TSS (9.69 Brixo), high pH (4.71), greatest ascorbic acid (140.90 mg 100g-1), less titratable acidity (0.74 %), less weight loss (8.60 %), less decay incident (19.36%), was noted on fruit coated with 15% Aloe vera gel, while in guava cultivar, highhest desirable score for the studied traits were noted on cultivar Safeda Allahabadi. In storage days, greatest fruit firmness (4.03 cm-2), less TSS (7.75 oBrix), less pH (4.42), high ascorbic acid (187.10 mg 100g-1), high titratable acidity (0.96 %), less weight loss (0.00) and less decay incidence (0.00) was noticed on fresh day while high appearance score (8.42) and taste score (8.42) was noted at 6 days of storage. From the above finding it is concluded that guava cultivar Safeda Allahabadi coated with 15% Aloe vera gel when stored up to 6 days showed better results on shelf-life and post-harvest quality of guava fruit.
