The study sought to identify the factors influencing adoption intensity of certified maize varieties. The data used were obtained from a sample household survey of 420 maize farmers, using structured questionnaire. A triple hurdle model was adopted to estimate the determinants of adoption; considering awareness, adoption and intensity as three separate stages of the adoption decision. The result showed that the drivers of farmers awareness, adoption and intensity of usage may not necessarily be the same, and where they are, not of the same magnitude and direction. However, age, education, membership of association and frequency of extension advice were found to be statistically significant. In addition, awareness and adoption were likely to be increased with household heads being males. It was also discovered that though some of the farmers were fully aware of the existence of some certified maize varieties, majority lacked detailed knowledge and technical know-how. There is need for creation of awareness through an excellent trained extension and restructuring of the educational sector to improve on the adoption process as well as improve maize productivity in the country.
