| Abstract:
A coordinated approach is being attempted in India to reduce the post-harvest losses of mango. The study includes assessment of losses at various stages of post-harvest operations and reduction of these losses by introducing improvement in pre-and post-harvest techniques and is being conducted at locations in different parts of India. Assessment of losses indicated that fruits discarded in the field was 1.3%. Culled fruits ranged from 12 to 18% and were sold at lower prices. Physiological loss in weight during transportation was 3.68%; there was no other loss provided the mature green mangoes were packed carefully. During ripening in boxes total loss was 7.53%; loss during pile ripening was much higher. Pre-harvest spray of calcium was useful in checking senescence and improving storage life, marketability and colour development. Pre-harvest spray of fungicide was effective in controlling storage disease due to anthracnose and stem end rot in mango varieties as follows: Dithane M-45 (0.2%) and Captan (0.2%) in cultivars Neelum and Totapuri, Bavistin 0.1% in Alphonso and Topsin-M (0.1%) in Dashehari. Alphonso fruits harvested with less than one specific gravity were free from spongy tissue and the incidence increased with the increase in specific gravity. Experiments proved that mangoes harvested with stalk could be stored better. CFB box with partition was found to be best for packaging and transporting of Alphonso. Pre-cooling of mango to 12/deC with 500 ppm Bavistin/Captan increased the shelf life of Alphonso and reduced the incidence of spongy tissue. Vacuum impregnation of Ca in mango resulted in delay in ripening and increased the marketability. Post harvest application of Bavistin and Topsin-M proved to be effective in controlling storage disease of mango. | |
