Experiment Background
|
Mango (Mangifera indica L.) is the oldest and choicest fruit of the world. Mango is believed to be originated to South East Asia, Indo Burma region, in the foot hills of the Himalayas (Mukherjee, 1951). India ranks first in area and production by 20.80 million MT from about 2.30 million ha area with the productivity of 8.9 MT/ha (Anon., 2019). India has a rich wealth of mango germplasm with more than 1,000 varieties grown throughout the country (Yadav, 1997). Among them most of the cultivars are Kesar, Alphonso, Rajapuri, Dashehari, Totapuri, Amprapali, Langra and Sardar.
Pre-harvest bagging of fruit can also reduce the incidence of disease, insect-pest and mechanical damage, sunburn of the skin, fruit cracking, agrochemical residues on the fruit and bird damage (Sharma et al., 2014).
Among various chemicals and plant growth regulators, the pre-harvest spray of CaCl2 reduces the weight loss, delays the ripening of fruits, increases the shelf life, physico-chemical parameters and organoleptic quality of mango fruits (Karemera and Habimana, 2014). Madani et al. (2014) reported that the pre-harvest application of 2% CaCl2 improves the quality and decreases the enzymatic activity in papaya fruits during the storage. Gibberellic acid in proper concentration and at appropriate time have been found to enhance the fruit setting and retention of fruits, fruit size, increase the yield, decrease fruit drop, improve the physico-chemical characteristics of fruit through modification of various physiological and bio-chemical processes of plant (Pandey and Sinha, 2013). Hence the aim of the present study was to determine the effect of fruit bagging and chemical spray on post-harvest quality and shelf life of mango fruits cv. Kesar.
