Resumen
Descripción
The Brazilian agricultural research system was developed under the influence of the diffusion model imported from the more developed countries (5). The model implies a freedom of choice in research projects so that scarce resources can be allocated to a broad range of research topics depending on the investigator's decision. The tendency to develop research activities oriented toward solving real problems was supposed to result from pressure by farmers on government research agencies. Extension services were seen as the means of bridging the gap between research agencies and farmer fields.
