ABSTRACT
Sweet potato (Ipomoea batatas) is grown in most parts of India. Presently about 80,000 ha are under cultivation. However, consumption is less than 3 kg per capita per annum, a negligible amount when compared with other countries. Proper curing and storage might help in assuring a good market. Sweet potatoes are usually marketed soon after harvest and are generally stored in jute bags. Main storage problems are the sweet potato weevil, diseases such as soft rot, and physiological changes (reduction of starch and increase in sugars and dextrins).
There is no organized cultivation of edible aroids, although they are widely grown throughout India as intercrops. Corms are processed into chips and flour. During storage, soft rot can occur, but the damage is negligible. There is a general reduction in starch and an increase in total sugars during storage.
Improvement in storage techniques will prevent damage as well as deterioration in quality.
