The main objective of the program was to obtain qualitative data on the value of Radio Farm Forums (RFF), to both the farmers and the extension service, in terms of facilitating two-way communication between the two parties. The concept of RFF is to provide agricultural information through integrated use of mass media and interpersonal communication channels (radio, publications, field worker visits) for an audience which has been organized into forums. The project was conducted in eight villages in Khon Kaen Province, Northeast Thailand, which were selected (out of 47 villages) by application of the quartile ranking method to existing socio-economic and agro-economic data. A training program was developed for forum leaders from the villages. The RFF were broadcast once a week for 20 weeks, with the leaders conducting discussion periods immediately after each program. The RFF (1) succeeded in organizing groups of farmers and maintaining their interest in the project; (2) demonstrated the reinforcing effects of relaying messages through several means of communication; and (3) illustrated a virtually self-contained model for extension program planning and implementation.
