methodologies to promote the use of appropriate technologies by farmers. For this purpose, inter-institutional linkages with the extension agency (DIGESA) were developed, collaborative efforts were established with cooperatives and other farmers groups, and a strong support was given to the private sector to promote a strategy for seed production and commercialization that was successful (Ortiz, 1980; Castillo and Jurez, 1985). Less than ten years after ICTA was founded, Guatemala had registered significant increases in basic grains production that covered the deficit of previous years and have since then, along with oilseeds (sesame), provided exportable amounts that has improved its international exchange balance (Castillo and Jurez, 1985). THE RESEARCH EXTENSION LINKAGE With the new research approach and a renewed interest in promoting the use of appropriate technology, ICTA and the Directorate of Agricultural Services (DIGESA), the extension agency, signed a letter of agreement in 1978 that would expedite the joint activities of those institutions for the purpose of technology transference. The most significant of these efforts in terms of success, has been the Courses for inter-institutional Technological Linkage that provided the extension agents with the opportunity to participate in on-farm research activities. With their involvement in the technology generation process, the extensionists improved their effectiveness in promoting the use of new technologies (Ortiz, 1980). But still, the degree of effectiveness in technology transference has not been considered adequate. technology has been reaching the farmers but not in the same intensity in each region or in every group. In spite of the inter-institutional efforts for the promotion of new technologies, and the evident impact of these technologies on food production, there remains a group of factors hindering the diffusion of technologies to a larger number of farmers.
