The impact of a cassava technology transfer programme on adoption level by small farmers was assessed by interviewing 7 5 each of beneficiary and non-beneficiary farmers over a period of four years. The results indicated significant improvements in adoption levels due to programme implementation. Non-monetary practices such as variety, setts h-1, sett length, planting method, and spacing were correctly adopted by almost all farmers even after programme withdrawal. The programme was effective not only in increasing the number of farmers applying fertilizers to cassava, but also the quantity applied. It was noted that the introduced varieties had spread to about 17% of the total cassava-growing area of non-beneficiaries in a three-year period. Also, there was substantial improvement in the adoption of various practices by this category of farmer in the programme villages. The extension implications arising out of this investigation are discussed.
