ABSTRACT Since 1973, the Instituto de Ciencia y Tecnologa Agrcolas, (ICTA) in Guatemala, has developed a model fr agricultural research that focuses in on-farm activities, farmers' participation. and the collaborative effort of regional multidiscipinary teams. By the early 80's this model had been the 'key mechanism in an overall agricultural sector strategy that made Guatemala a self- sufficient country. and even exporter, of basic grains. Although a successful experience, the potential impact of this model in the national economy has been hindered by a "limited" extension of the research results m some regions of the county. The extension agencies, DIGESA and DIGESEPt, had their partrigBtion restricted to credit planning and supervision activities, and whatever effort they invested in working with ICTA has been, in most cases, due to good relationship between the institutions' authorities at the regional level and the own personal interest of the extension agents i"the communities. A new project based in the technology transference concept, rather than extension educationn) will provide ICTA, DIGESA and DIGESEPE the framework to participate jointly in the integrative effort of generation and transference of appropriate technology for small farms in Guatemala. A "multiplying" effect in technology transference resulting from rural leaders (lderes agrcolas) working with organized farmers groups in "tranference plots" provides the basis for expected success. These rural leaders will be recruited by the project, trained along. with extension agents in the new technologies by ICTA's field teams, and coordinated in their activities at the community level by the "new" extension agents.
