The acceptability and utilization of a newly introduced Cassava (Manihot Esculenta) in Marigat, Baringo County, necessitated this study. This paper is drawn from a study that was conducted on Marigat to establish the level of utilization of the cassava roots. A total of 51 introduced cassava varieties were grown and all harvested at 16 months by KARI-Marigat. The study recommends that there should be greater efforts to promote cassava breeding for better food, nutrition and livelihoods that will enable people to live productive lives since cassava is staple in the diet of 90% of respondents in the study area. Deliberate efforts are necessary for leveraging agricultural research towards improved production of cassava roots with better culinary, nutritional and keeping qualities. This may enable communities in vulnerable areas such as Marigat to benefit from improved cassava varieties towards attaining Kenya’s Vision 2030’s for sustainable livelihoods and development.
