<p>Field peas play a substantial role in the socioeconomic lives of both the urban and rural society in Ethiopia. It is the cheapest source of protein, food security and a source of cash income. However, the field pea marketing system is under developed and inadequate due to different factors. Thus this study is attempted to investigate drivers of market participation and its extents among smallholder field pea farmers in Jabi Tehnan district, Ethiopia. A samples of 121 field pea producers was selected from the total field pea producers through random sampling. For this study, interview schedules and focus group discussion tools were used for data collection. Both descriptive statistics and Heckman two-stage models were used to explore and interpret the output of the gathered data. The outcome of the first Heckman two-step model shows age (9.8%), educational status(5.8%), lagged price(0.018%), and market information(5.7%) are statistically significant and influence the field pea market participation decision. The findings of the 2nd Heckman two stage reveals that education, family size, land allocation, distance to market, experience, and access of market information were significantly affect the intensity of market participation of field pea producers. The findings suggest that the government, NGOs, and other responsible bodies should improve rural infrastructure, price and information systems.</p>
