Effect of Pre-harvest Nutrients Application and Bagging on Quality and Shelf Life of Mango (Mangifera indica L.) Fruits cv. Amrapali

The present experiment was conducted to study the effect of pre-harvest bagging and spray of CaCl۲ and K۲SO۴ on quality and shelf life of mango fruits cv. Amrapali during two succeeding years. Trees of Amrapali mango were sprayed three times at ۳۰, ۲۰, and۱۰ days before harvesting and bagging with brown paper bag ۲۰ days before harvesting of fruits. Harvested fruits were stored under the ambient temperature (storage at room temperature) and observations were taken at three days intervals upto ۱۸ days. The results indicated that the pre-harvest treatment of ۲% CaCl۲+۱% K۲SO۴+bagging was found superior to improve the quality of fruits in respect of highest fruits weight, firmness, TSS, ascorbic acid, total sugars, and β-carotene content with minimum black spotted fruits per cent and maintained it throughout the storage period upto ۱۸ days. Fruits treated with ۲% CaCl۲+۱% K۲SO۴+bagging showed shelf life up to ۱۲ days with lowest weight loss and highest organoleptic quality as against ۶ days of untreated fruits (control).
