Abstract

This study uses interrupted time series analysis and time series data collected from FAOSTAT(2016) to analyze the macro and long term impact of adoption of improved maize varieties on maize yield in Cameroon. The results suggest that adoption of improved maize varieties has no significant impact on maize yield neither in the first year of intervention or release (1987) nor over years. Therefore, the study appeals for further studies to determining the effectiveness of improved maize varieties in boosting the maize yield.
