Agricultural extension services provide farmers with important information, such as patterns in crop prices, new seeds varieties, management practices and training in new technologies. Provision of such information enables farmers to optimize the utilization of the scarce resources at their disposal. In the past, a number of agricultural extension models have been employed with varying levels of success in developing countries. This study sought to document the effectiveness of the public-private partnership (PPP) model in provision of agricultural extension services in Samburu, a remote rural area of Kenya. Comparison of greenhouse tomato mean yields and standard deviations obtained by public private partnership was made using ANOVA and Chi square.  Honest Significant Differences tests were also derived and used in this analysis The mean± standard error (se) yields per greenhouse varied significantly by the various models assessed (786.3±180.7, 1881.9±283.5 and 1909.1±213.5 kilograms corresponding to the public, PPP and private models respectively (p<0.001). Tomato productivity in greenhouse units under public model were statistically significantly less when evaluated against those under PPP model (mean± se difference of 1095.6±147.0 kilograms (p<0.001). Yields in greenhouse units under private and PPP models were not significantly different (p=0.972). These variations mirrored the levels of adoption of modern agricultural practices and technologies in the three models of extension services provision. The current study adds to the accumulating evidence that PPP may be the panacea to the ailing public agricultural extension services. Creating effective operational linkages between extension service providers and, perhaps, other key stakeholders such as input suppliers, credit and research institutions has the potential to improve the delivery of agricultural extension services to farming households in resource poor settings.
