Abstract

Horticulture accounts for more than half of Uganda’s agricultural output, yet crops such as tomatoes and onions remain only marginally profitable despite the country’s favorable climate. To assess the state of their marketing, a study was conducted across five watershed irrigation schemes of Ngenge, Tochi, Wadelai, Mubuku II, and Doho. Researchers interviewed 56 key informants and 174 market vendors using questionnaires that explored market actors, their roles and interconnections, seasonal trade dynamics, pricing, supply and demand, gross margins, and both opportunities and constraints. Data were analyzed using Microsoft Excel and SPSS. The findings showed that nearly half of the markets (46%) were underdeveloped, with women and youth making up the majority of vendors (78%). Farmers were the main suppliers, but often overlapped with other market roles. Seasonal fluctuations affected tomato and onion availability, with oblong tomato varieties being most popular. Key challenges included poor storage facilities, high market fees, and price volatility. However, strong local demand, access to export channels, and opportunities for off-season production highlight promising avenues for improving the profitability and sustainability of tomato and onion marketing in Uganda.
