Abstract
This study investigates the early adoption of modern groundnut varieties in the pilot sites of the Groundnut Seed Project (GSP) in Mali, Niger and Nigeria following government and donors’ investment. Seventeen varieties were disseminated in the pilot sites of the three countries. Uptake has increased significantly during the last three years partially as a result of project intervention. The proportion of area planted with modern varieties has increased by 22% in Nigeria, 12% in Mali and 10% in Niger in the pilot sites since 2003. Farmers using modern varieties have derived significant yield gains of 24%, 43% and 31% over the local varieties in Mali, Niger and Nigeria respectively. The modern varieties had significantly lower per unit cost of production estimated to 9.8%, 11% and 11% in Mali, Niger and Nigeria respectively. The net income derived by adopters is 66% higher than non-adopters in Mali, 73% in Niger and 111% in Nigeria. Relative to household types, income gains are estimated to be less than 20% compared to poor households in Mali, while it is more than 50% in Nigeria. Results from the Logit models indicate that the major determinants of adoption in the three countries include the participation of farmers to on-farm trials, the build up of social capital through the empowerment of farmers’ associations and small-scale farmers at producing and marketing seed. Constraints to adoption remain the poor access and availability of seed of modern varieties, pest and disease pressure in at least two out of three countries. Tobit results indicate that intensification of modern varieties is dependent essentially on seed availability, social capital, exposure to the varieties through farmers’ participatory variety trials.
