  • 3. Sweetpotato is a major source of energy, minerals, and vitamins In West Africa, sweetpotato is gradually becoming an important crop because of its potential as a food and industrial crop, and can be produced in almost all the agro-ecological zones in the sub- region. Sweetpotato is relatively poor in essential amino acids with tryptophan, methionine, and Lysine being the most limiting and to a lesser extent isoleucine, theorine and leucine. An increase in these essential amino acids in the crop will be more beneficial.
