One of the primary development challenges hindering poverty reduction in Africa is the existence of a yield gap between female and male farmers. However, previous studies conducted in Ethiopia have largely overlooked the role of gender-related factors in influencing this gap. This article aims to address this gap by examining the chickpea yield disparity between female and male farmers and identifying its determinants. Data were gathered from 325 respondents (163 male and 162 female farmers) in 2019, combining survey responses with qualitative insights from discussions in two women farmers' groups, two men farmers' groups, and four key informant interviews. T-tests and linear regression models were applied to quantify the extent of the yield gap and analyze the factors contributing to it. Additionally, thematic analysis of the qualitative data was conducted to complement the quantitative findings. The study revealed that female farmers produced 29% less chickpea yield in the 2019 production year compared to their male counterparts, and this difference was statistically significant. Factors such as land allocation for chickpea cultivation, soil fertility, labor availability, chickpea variety (improved or local), access to extension services, and participation in farmers' cooperatives were identified as significant contributors to the yield gap. Beyond these technical aspects, gender-related challenges like unequal treatment, restricted mobility, labor demands, and religious/cultural taboos were also factors impeding the productivity of women farmers. Addressing the yield gap necessitates an inclusive approach in all agricultural development endeavors, recognizing and rectifying gender-based disparities to enhance the productivity and livelihoods of female farmers.
