This study provides primary information of sweet potato market value chain analysis in Sidama and Wolayita\zone in SNNPR. The survey was conducted in two districts for each zone with the total sample of producers 134 and 35 traders for each market participants to diagnose the farming system and identify the market actors and their functions along the value chain. The objective of the study was to develop value chain maps and identify the major sweet potato value chain actors, carry out value chain and economic analyses, identify the constraints faced by sweet potato value chain actors and identify strategic intervention areas for increasing the competitiveness of sweet potato value chain. The analysis was done using descriptive statistics, such as frequency, mean, chi-square and t-test for discrete and continuous variables whether identified factors were statistically significant or not. The economic analysis on the marginal cost-benefit among the markets that participated were calculated.

The results considerably reflected producers having comparative advantage in terms of location and agro ecology in producing sweet potato and improving the productivity. Along with increasing the traditional seed supply system, introducing improved seed production and marketing system can significantly contribute to the solution. The seedling sweet potato producers can then be linked with ware sweet potato producers to create access to market for their business. Thus, improved sweet potato seedlings should be replaced not to lose their genetic potential of the crop with the involvement of the relevant stakeholders like Ministry of Agriculture, Bureaus of Agriculture, Research Institutions, NGOs and Seed Producers. The system should enable farmers replace the improved varieties at regular intervals to improve production and productivity and ably provide significant supply to market participants to sustain the market linkage and competitiveness.

Improving farmers’ access to agricultural equipment through different strategies such as credit would help to increase the participation decision of the farmers’ in Seedling/tuber contract farming for multiplication of new varieties of potato as recommended. On the other hand, efforts aimed at promoting the participation of farmers in contract farming and linkages to market participants ease the marketing transaction in due course.


Keywords: Survey, market, value chain map, value chain actors, economic analysis, constraints, strategic intervention and recommendations.
