While much work has been done on the factors determining the adoption of agricultural technologies, little research has been conducted on the factors that predispose farmers to discontinue the adoption of innovation. Following a survey of arable crop farmers in two states of southwestern Nigeria, econometric analysis was conducted in order to identify variables significant in the farmers’ discontinuance behaviour. The variables included in the study are Attitude, Extension visit, Feedback provision, Marketability and Input availability. Tobit model was estimated on the data collected during the 2002 growing season. From the estimation, significant variables leading to discontinuance of improved maize and cowpea varieties were identified. Foremost among them is extension visits.
