The study looked at how agricultural extension services in Kenya were managed and found that the traditional training and visit system did not have a significant impact on increasing agricultural productivity. The projects aimed to improve extension services and boost productivity, but the results showed limited success in getting farmers to adopt recommended practices. This suggests that the current approach may not be the most cost-effective way to provide extension services in Kenya. The study recommends focusing on specific areas and groups where the impact is likely to be greater, using less intensive methods for wider coverage, to make extension services more effective and efficient.
