The tomato supply chain is not well depicted, which affects the income share of the farmers, as a result, they face difficulties in accessing food. Therefore, the study investigated the impact of the income share of primary actors on household dietary diversity in the tomato supply chain. A multistage sampling procedure was used to select 800 participants for this study. The data were analysed using a zero-one inflated beta regression model, the Herfindahl-Hirschman index (HHI), and the Household Dietary Diversity Score (HDDS). The findings revealed that marketers earn the most (84% of total income) in the supply chain. The remaining 16% of the income is split between farmers (15%) and transporters (1%). A larger percentage (63%) of the farmers consumed 3 food groups or fewer. It was further found that income share, along with other socioeconomic characteristics such as gender, age, formal education, farming experience, informal education, the average tomato yield, years of experience in tomato farming, number of working-class farm members, cooperative membership, access to credit service, and processing with various methods, had a significant impact on the probability and intensity of food security. The study indicated that greater revenue among tomato supply chain players enhances their households’ food security.
