The aim of this study is to establish that indeed communication is at the heart of change. Regardless of the sophistication of technology, its use or adoption is dependent upon the communicative processes amongst stakeholders leading to its formulation, conceptualization and design. In the first part, a general review of existing body of literature is presented. This shows that there is a major gap in the extension arm of the agricultural system in Nigeria, because as at present the top-bottom approach that has not yielded much impact is still in use for information dissemination to farmers. The thesis then goes further to interrogate the National Agricultural Extension and Research Liaison Services (NAERLS) Zaria, with the view to ascertaining the participation or otherwise of local farmers in the research and innovation process. The over reliance on mass media by NAERLS to propagate the outcome of research findings in spite of its limitation and non-participatory posture is one of the key findings of this research work. This study goes further to interrogate the rationale behind the continuous use of this method amongst others and recommends the institutionalization by NAERLS of traditional forms of entertainment as extension media. Songs, dances, poetry and drama can convey information in an interesting way. It concludes that the process of communicating research and innovation needs to be reviewed to make for the participation of farmers and all stakeholders in the research and innovation process.
