EFFECT OF ADOPTION OF IMPROVED AGRICULTURAL TECHNOLOGIES ON THE PRODUCTIVITY OF YAM FARMERS IN GHANA
yam farmers in Ghana. The study applied mixed methodological approach in both data collection and analysis.
Econometric and qualitative tools such as Two Stage Least Square IV regression model was used to analyse the
effect of adoption of IATs on the productivity of yam famers. The focus group discussion transcripts were
subjected to thematic analysis to understand the themes that run across the data. These were used to complement
the quantitative data. The results show that the adoption of IATs has a positive and significant effect on the
productivity of yam farmers in the study area. The study recommends that yam be included in the list of root and
tuber crops in the priority crops of the government of Ghana, since it has the potential of enhancing the food
security and livelihood of the rural poor, and increase the foreign exchange earnings of Ghana, being the foremost
exporter of yam.
