The data was collected on the socio-economics characteristics, rate of adoption, determinants of adoption and drivers and barriers of adoption of improved sweet potato farmers using android devices programme with the census and survey processing system (CSPro. 6.3) software package. The data was analysed using descriptive statistics. The result suggested that there was higher magnitude of adoption in the treatment area than the control area, this was as a result of the NARC research activities on OFSP genotypes. Result suggested that the socio-economics factors that significantly influence the probability of adopting at least one improves sweet potato variety of the study area were; marital status, educational level, household population, main crop cultivated and sweet potato production cycle. Also, the result suggested that the probability of sweet potato farmer to adopt one improve sweet potato variety was determined by farmers’ access to extension services, access to loan and belongingness to an ABC.
