High-quality onion production begins with high-quality onion seed. Ensuring farmers’ access to quality seed requires the use of research-proven techniques. This project aimed to improve the onion seed system by strengthening producers’ capacity to produce certified onion seeds. The project built the capacity of producers through training of trainers, demonstration plots, and field/open days. The improved techniques stood out distinctly from traditional practices and allowed the production of 800 kg certified seed at the community level. The overall top performer of cultivar comparison trials was the local onion landrace Goudami, which outperformed imported onion varieties in both yield and germination. About 900 households from 90 farmers groups benefited from the project, especially women; today, onion is no longer a men’s crop
