| Abstract:
Tomato is the second vegetable crop consumed in Colombia. Important productive zones are located in Cundinamarca, Boyacá, Antioquia, Valle, and Santander, with the area about 11,304 ha. Different types of producers apply different farming systems and conditions of management and commercialization. Due to the necessity to characterize the circumstances of these production systems in a precise form during the first semester of 2008, primary information was taken in producer farms, participative diagnostics were realized including farmers and technicians, and secondary information was obtained from several sources in order to realize this characterization. The information was analyzed by multivariate analysis in its procedures, principal components, cluster analysis, and discriminate analysis. The cluster analysis showed that 8 principal components explained 75% of whole variance between the analyzed systems. We determined that exist 8 productive clusters that grouped in whole 38 farm types with 100 cultivated lots. Discriminate analysis confirmed that 6 clusters exist. We determined that, for Cundinamarca and Boyacá, there are 6 existing productive systems, which were described in their physical, biotic, economic and socio-cultural components. | |
