The objective of the study was to characterize the 'rice' production plots, a concerted survey of 50 questions used was, ofwhich 35 questions related were to the socio-economic component and 15 related to the environmental component. Amultivariate analysis carried out was to form groups or clusters, whose purpose was to group the plots and formconglomerates (clusters) with a high degree of internal homogeneity and external heterogeneity. For the processing of thedata, the statistical software Info Stat used. Was Among the most important results, it was found that the majority ofproducers own their plots, sow between 0.5 to 5 hectares, the yield of grain rice is between 5 000 to 8 000 kg/ha and all doconventional agriculture. The conglomerate analysis classifies the plots into 6 groups, the producers of conglomerate 1 sharethe greatest number of variables (21), having in common the variables: ownership of the plot, use of chemical fertilizers,burning of weeds and harvest residues, use of agrochemicals. The producers of conglomerate 5 have 12 variables incommon, among them: they do not incorporate organic matter, they do not rotate crops, they do not use biological control,and they do not use repellents. It recommended is to promote the rotation and association of crops under the diversityprinciple; likewise, to promote the self-sustained fertility of the soil, and to include in the productive process, the integratedmanagement of insect pests and phytopathogens.
