Agricultural extension can play a crucial role in relieving farmers’ information constraints and encourage adoption of improved agricultural technologies, thereby potentially increasing yields and income. Promoting cost-effective agricultural extension systems is especially important in developing country economies that are highly dependent on agriculture. Agricultural extension systems tend to rely primarily on two models for disseminating information about new technologies: farmer field days and farmer-led demonstration plots. In this seminar, Annemie Maertnens presented results from a 3ie-funded impact evaluation in Malawi on the effects of these two primary models on farmer learning and adoption of integrated soil fertility management practices.
