Abstract: The study was conducted in Agarfa district, Oromia regional state Ethiopia. A total of 120 farmers were selected in the study area. The x^2and t-test were used to analyse the independent dummy and continuous variables respectively. Generally, farmers have showed favorable response in participating in the community managed irrigation scheme utilization and management system. Binary logit model was applied to analyse the factors affecting farmers participation in communal irrigation management system. . The findings of this study indicate that any effort in promoting communal irrigation scheme management system should recognize the socio-economic, household, institutional, and others factors for better use of community managed irrigation scheme. Taking the specific characteristics of farmers into account in introducing and promoting community managed irrigation scheme projects may help policy makers to come up with projects that can win the hearts and minds of the farmers.
