This study examines the impact of agricultural extension services on crop yields in small farmer communities within central Madagascar. A mixed-method approach incorporating surveys and observational fieldwork was employed to gather data from farmers across the region. Statistical techniques were used for data analysis. Farmers who received targeted agricultural advice experienced an average yield increase of 15% compared to those not exposed, highlighting the effectiveness of specific extension services in enhancing productivity. The findings suggest that tailored agricultural extension programmes significantly contribute to increased crop yields among smallholder farmers in Madagascar. Policy makers are advised to invest more resources into targeted agricultural extension services as a cost-effective strategy for boosting rural livelihoods and food security.
