Faith Okiror posted: 'A wide range of value added orange fleshed sweet potato (OFSP) products such as mandazi, cakes, cookies, biscuits, quality porridge, juice, animal and poultry products can be got from OFSP. In addition, OFSP varieties are adequate and cheaper sources of Vitamin A for children and breast feeding mothers.'
Max Olupot shared that International Potato Centre (CIP) has been in the forefront in the dissemination of the OFSP in Uganda, Kenya & Tanzania. The extension approach used was FFS and he was part of the teams from 2005-2006. This built very strong farmer groups some of which transformed to marketing associations like in Kyere- Uganda, Kakamega in Kenya, etc. There have been a number of follow up projects on OFSP in Eastern Africa and a wealth of experience exists. FAO was in the vanguard in training and backstopping in Uganda where James Okoth has been lead person, Julianus in Tanzania, and Godrick in Kenya.
