Abstract:
Despite, increasing the agricultural sector's productivity is seen as the main path out of 
poverty in the country; Ethiopia has not yet realized its full agricultural potential as farming 
practices are still subsistence-oriented. In this regard, Cluster Farming (CF) is practiced 
more recently as an effort to transform subsistence farming. However, little is known about
CF in the study areas. To this end, this study aimed at identifying the determinants of cluster 
farming participation and impact of cluster farming on the smallholder wheat farmer’s 
productivity in the two districts of Arsi Zone, Ethiopia. The study utilized cross-sectional data 
and multistage stratified sampling procedure to select a total of 381 respondents from the two 
districts. The study employed both descriptive and endogenous switching regression model.
The study result indicates that sex, education level and social responsibility of the household 
head, farm size, access to training, access to information from government extension, 
membership in farmer’s cooperative were affect CF participation positively and significantly 
whereas, distance to the nearest market has a negative and significant effect. Furthermore, the 
study shows that, if participants had decided not to practice CF, their wheat yield and net 
wheat value would have decreased by 33.57% and 40.08% respectively. Similarly, had non participants decided to participated, their wheat yield and net wheat value would have been 
increased by 46.79% and 102.49% respectively. The study recommends, policymakers and 
development organizations should consider cluster farming as a main strategy to increase 
smallholder farmer’s productivity. This study also argues that, institutional and government 
assistance in the areas of education, extension service, training, infrastructure development 
(particularly access to markets), and cooperatives is critical. Moreover, Policy and 
development interventions should address the issue of gender disparities in CF participation.
