The costs of the process are decisive factors in the decision of the accomplishment of investments. The investments in the agricultural production have been object of concerning for the authorities who are responsible for the economy planning and mainly for the farmer. Making a decision based in economical parameters that are external to the producing unit has not been taking enough information for the farmer so that they feel secure about their investments in order to obtained a higher level of productivity. The searches for productivity levels that are in an increasing rate not always have the same level of profit. The use of geoestatistic instrumentals to create unique productivity parameters based on the variability is an available alternative so that the agriculture manages his activity. The reached results demonstrate that the variability of the parameters of costs provides different results in a same unit of production and the multivariate analysis of groupings, "cluster analysis" of the costs and of the results showed the existence of different similarity levels of the similarity within the yield analyzed. The geoestatistic analysis of the variables of tributes variability about the plant of the variables of the soil properties, compared with the variability of the productivity and of the profit, provides parameters for the decision making about investments in production costs.
