摘要

Sweet potato [Ipomoea batatas L. (Lam.)] is a staple food in many of the developing countries of tropics and sub-tropics also serves as animal feed and raw material for the industries. Sweet potato area globally has been showing a declining trend. This decline was more predominantly seen in Asia followed by Latin America. Sweet potato yields globally showed an increasing trend in all periods, except during 2001-2010 where it recorded a significant decline at 1.0%/annum. This to some extent and significant production growth in Africa compensated for the effect of global decline in sweet potato area on production. Asia continued to have its dominance in spite of the fact that area, production and yield of the crop has showed a declining trend during the past decade. All the major sweet potato-growing African countries recorded significant growth in sweet potato area and production during 1961-2010. Serious and concentrated efforts are needed to exploit its potential in producing many value added products and promoting the orange fleshed sweet potato especially in the African continent to reverse the current declining trends.
