Abstract
This study employed a Tobit model to examine factors that influence the adoption and
intensity of utilisation of improved maize varieties in the West Shoa Zone in the central
highlands of Ethiopia. The estimated results indicate that level of education, household
labour, farm size, extension services, farm income, and timely availability of improved maize
seeds significantly influence the adoption and intensity of use of improved maize. It also
showed that the impact of off-farm income and age of the household head on adoption and
intensity of use of improved maize seed was insignificant.
