The objective of this work is to analyze the coffee yield and quality variability cultivated in small farms of the region of Viçosa, Brazil. For that, small coffee field located in a mountain area were characterized; the management profile of the producers of selected areas was obtained; an activity follow-up system for small producers to accomplish the coffee management was developed; it was created a system based on SIG techniques to aid the management of the coffee production, the coffee yield and quality; and the correlation between parameters of the production system and the coffee quality and yield was analyzed. The work had as results the maps of the elevation digital model, the coffee field orientation and slope maps, and the monthly global solar radiation maps, for the months of January, February, March, April, May and June of 2005. Also, the coffee fields of each farm were characterized. The year when each coffee field was established, the variety and crop spacing in each coffee field, the area and the number of coffee plants in each field, were organized in tables. The following conclusions were obtained: the studied areas presented a high population of plants per unit of area, in average, a crop spacing of 2.5 x 1.0 m, with 4,000 plants per ha-1 were found; the organization and the technology level used in the farms are associated to the school degree of the producer and their participation in coffee producer associations in the last 10 years, as well as the technical support of EMATER in the awareness about the appropriate management of coffee fields; the use of technology help the producers to have a better perspective in the farm organization and a better production management and to have more profits; the relationship among the employees, and among employees and managers is very satisfactory in the small farms, making possible to develop any methodology that brings benefit to the producer; the producers stay the whole day in the farms and make the activities of farm planning; the lack of financial resource is the main restriction for implanting of the farm plans; the owners try to organize themselves in the farm through annotations made in notebooks and/or cash register books; the management profile of the small mountain coffee producers was the flexible style, they use few information to decide, but try to analyze it under different aspects, choosing for the most appropriated; the developed notebook allowed the producer to see the coffee field map and to have a better data organization in their notes; the Activities Follow-up System of the Coffee growing allowed the agricultural extension technician to manage the field information like the cultural practices, fertilization, leaf analysis, soil analysis and yield, as well as to visualize the representative maps of all of the registered farms, aiding in the decision, providing a better evaluation of the production costs; and, there were no yield and quality correlation related to the variables: altitude, solar radiation, physical and chemical soil attributes.
