Agricultural extension programs often evaluate their gender strategy by the proportion of female participants. However, female participation is not necessarily conducive for reaching program objectives. We analyze whether participation of female farmers in an agricultural extension program in South-Kivu increases adoption of three technologies: improved legume varieties, row planting, and mineral fertilizer. Joint male and female program participation leads to the highest adoption rates. Female participation is not conducive for the adoption of capital-intensive technologies while it is for (female) labor-intensive technologies. Participation of female-headed households is more effective for technology adoption than participation of female farmers in male-headed households.
