This study measured the impact of extension services on cocoyam production in Ogun State by comparing the output of farmers visited by extension workers (FV) with those not visited (FNV). A multistage sampling technique was used to select 90 farmers. Data were analyzed by means of both descriptive and inferential statistics. The regression result for the cocoyam production model revealed that FNV also enjoyed the benefits of extension services through their interaction with FV or cooperative societies in the study area in what could be termed a "trickle down" effect. These findings suggest that extension can help to close the gap between the output attainable with existing technologies and those actually realized by farmers. © 2011 Copyright Taylor and Francis Group, LLC.
