In Nigeria, agricultural extension services have been dominated by the Agricultural Development Programme (ADPs) since the mid-1970s. However, the experiences of farmers are changing. Traditional extension services linked with production objectives and blanket recommendations can no longer meet farmers’ expectations. Therefore, extension practitioners need to meet this challenge by seeking private sector participation in the funding and delivery of extension services. This paper noted that extension services provided by the private sector, even when it is funded by government, is a positive feature and government can play a strategic role in identifying gaps in the provision of extension services that can be filled through a brokerage role or by contracting service providers. It then concluded that the sustainability of private sector participants in extension service delivery requires a new orientation among staff. This will require some investment in staff training and reorientation.
