Guava (Psidium guajava L.) is the fifth most important fruit crop of India, has a limited postharvest shelf life. This study explored the use of some postharvest treatments to extend the shelf life, post-harvest disease incidence and to assess the physico-chemical changes of fruits during storage and to study the effect of seasonal variation on quality and storage life of guava fruits (cv.L-49). Fully mature but green guava fruits were treated with different edible coating materials, chemicals, powder formulation of bio-control agent, hot water, and control. On the rainy and winter season, retention percent was found maximum with paraffin liquid 10%. Physiological loss in weight was minimum with the guar gum 1% in rainy season, paraffin 5% and gum acacia 10% in winter season. Regarding other horticultural traits like total soluble solids, ascorbic acid, total sugar, reducing sugar, non-reducing sugar content etc. were recorded maximum with gum acacia 10% in rainy season and winter. From this experiment, it is concluded that winter season guava fruits could be stored well as compared to rainy season fruits. Edible coating materials showed the better results in terms of extending the shelf life of guava fruits (cv. L-49) in both rainy and winter season as well as to maintain the qualities than the other chemicals.
