Irish potato is one of the most important economic crops in Tanzania contributing to household food requirements and income. In order to ascertain the contributions of Irish potatoes to stakeholders involved, this study aimed at determining the factors influencing Irish potato farmers’ decision to participate in the marketing and the extent of participation in Southern Highlands of Tanzania. Multistage sampling technique was used to collect cross section data from 497 Irish potato farmers. Cragg’s two step model was used to analyze data. In the first step Probit model was used to determine the factors that influence decision to participate in the market, while in the second step Truncated regression model was used to determine factors that influence the proportion of output sold. The results showed that socio-economic factors significant in the first stage are not necessarily significant in the second stage. Factors such as farming experience, farm size, price, education, extension service, credit and gender significantly influence the decision to participate in the marketing and the extent of participation. Policies need to enhance capacity of farmers through adult literacy programmes and help farmers to adopt the modern farming techniques that will lead to increased Irish potatoes output and market participation.
Key words: Irish potatoes, Market participation, Cragg’s two step model, Southern Highlands, Tanzania
