Effect of Post-harvest Treatments on the Shelf Life of Guava Fruit (Psidium Guajava L.) Cv. Dhawal.

Abstract

The present investigation was carried out at Post harvest Laboratory, Department of Horticulture, Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut to study the “Effect of post-harvest treatments on the shelf life of Guava Fruit (Psidium guajava L.) cv. Dhawal”. The experiment was conducted in a Completely Randomized Design with 11 treatments viz. To- Control, T1- Aloe vera gel 1%, T2- Aloe vera gel 2%, T3- Corn starch (0.5%), T4- Corn starch 1%, T5- Cassava starch 1% with sunflower oil, T6- Cassava starch 2% with sunflower oil T7- Cassava starch 3% with sunflower oil, T8- CaNO3 (0.5%), T9- CaNO3 1%, T10- Cassava starch 1% with sunflower oil and bee wax and their 3 replications, during the year 2023. . Corn starch 1% treated fruits showed the better results followed by Corn starch (0.5%). The Aloe vera gel were also found to be significantly superior treatments over the control in respect of storage quality and shelf- life. Based on results obtained in the present study, it can be concluded that Corn starch 1% was found to be the most appropriate treatment in Guava cv. Dhawal on account of better shelf- life. Therefore, Corn starch 1% can be adopted with great success in Guava cv. Dhawal for physico-chemical traits, storage, quality and shelf-life on commercial scale
