Studies on Post Harvest Quality of Rainy Season Guava (psidiumguajaval) under Various Pre-harvest Treatments

Ms. Lopamudra Singha, Ms. Vedashree M.S

The study was started from June 2015 to assess the effect of pre harvest treatments on post harvest quality of rainy season guava cv. ‘L-49’ at the Main Experiment Station and Post Harvest Technology Laboratory of Horticulture, Narendra Deva University of Agriculture and Technology, Faizabad (U.P.). The fruits of rainy season or Ambebahar guava crop are very poor in quality, having poor shelf life and numbers of fruits are infested with insect pests and diseases particularly fruit flies and anthracnose respectively. These problems occur due to prevalence of warm and humid condition in rainy season. To overcome these problems, the present investigation was formulated with nine pre-harvest treatments viz. CaCl2 2%, CaSO4 2%, Polythene bag, Brown paper bag, CaCl2 2% + Polythene bag, CaCl2 2% + Brown paper bag, CaSO4 2% + Polythene bag, CaSO4 2% +brown paper bag and Control. The treated fruits were harvested at fully ripe stage and stored at ambient condition.

The result revealed that the pre harvest treatment of CaCl2 2% + Polythene bag proved the most efficient in improving shelf life and fruit quality in respect of fruit size, weight, firmness, TSS, ascorbic acid, reducing sugar, non reducing sugar, total sugar and TSS : acid ratio, free from blemishes of pathogen and attack of fruit flies. Therefore, the combination of pre harvests treatment with CaCl2 2% + Polythene bag is suggested to the guava growers and traders to get sustainable guava productivity round the year and obtain a profitable price.
