Abstract:
In Ethiopia there have been numbers of farming strategies reform by government to improve
productivity of small scale cash crop productions to increase GDP. However implementation of
it does not give Eigen effects on rural production. For causes agricultural coffee productivity in
Mana district, Jimma zone were inadequate and farm characterized by poor productivity. This
study aimed to examine determinants of productivity in Ethiopia, a case of small scale coffee
producers in Mana woreda. This study used primary and secondary sources of data to address
research hypothesis and the sampling techniques that study used was multistage sampling which
researcher applies sample determination general formula of Yemanes (1967). The study
employed probit model to identify determinants of coffee farmers’ productivity in area and used
cob Douglas production function to analysis level of productivity. The finding of thise study
show, kola areas were suitable to coffee productivity than dega and woinadega areas with the
same identified factors having large numbers of effectively determinant factors to productivity
where in dega the least. So for dega and woinedega areas to incidence of factors to low
productivity resulted call for urgent intervention to curbs this problem. In line with gender, age,
education level, family size, land size, market distance, farm technology input, credit access and
climate change, was identified as significant determinants of coffee productivity in Mana farm
area. Explanatory variables related to effecient and ineffecient productivity have been identified
and tested by diagnostic tests. In general, this study provide evidence that certain demographic
and socioeconomic variables play key role in determining productivity in all rural areas of Mana
woreda. Thus coffee productivity policies based on those factors should ingredients to increase
productivity and targeted groups should involve in efforts that could address identified problem
