18 pages., via online journal., This study identified the communication platforms existing among researchers, extension workers, and farmers in Eastern Nigeria. Data were collected from 164 respondents using a questionnaire and analyzed using descriptive and inferential statistics. Results revealed that monthly review technology meetings and research-extension-farmer-input linkage system were major communication platforms used by researchers and extension workers. Communication platforms effective between extension workers and farmers were those that promote face-to-face interactions. The problems militating against effective communication among the stakeholders could be solved by considering the needs of the farmers, acquainting the policy makers with current research findings, and frequent use of more interactive communication platforms.
