Introduction Sweet potato1 Ipomea batatas a member of the Convolvulacae family is grown in over 100 countries mostly by small holder farmers. It has a high yield potential for biomass production is adapted to a wide range of habitats and soils and ranks among the world s top ten food crops on production volume. Sweet potato is a versatile crop. The roots are eaten as vegetables or are processed for diverse uses including making noodles and snack foods fermentation into alcoholic beverages and production of starch. The roots are a good source of edible energy in the form of starch and also provide a source of dietary fibre from nonstarch polysaccharides. Sweet potato leaves are rich in vitamins A and C and have relatively high protein content 25-30 of dry matter compared to other leafy vegetables. The carotene and anthocyanin pigments which are responsible for the yellow orange red or purple flesh colours of the roots are a source of natural pigments for the food industry. The roots leaves and vines are used for livestock feeding as fresh or dried material or after fermentation into silage. Fresh sweet potato roots normally contain between 20 and 50 dry matter depending on cultivar and developmental stage of the plant at harvest. Carbohydrates make up .
