Resumo: : Agriculture is considered an economic activity which contributes significantly to the production of part of the wealth earned in Parana state. In this way, the research on the efficiency of agriculture activity from the point of view of production costs becomes important, in order to know which costs can be reduced, to determine the possible constraints of inefficiency and to indicate the ways to increase efficiency, through the presentation of efficient and inefficient DMUs. Operations with machines, inputs, post-harvest, financial expenses and factor incomes are the input variables, and the final cost price of the sack is the output variable. The DEA model used is the output oriented BBC. The results show that 55.56% of the soybean crop, 38.89% of the wheat crop and 37.5% of the corn crop presented problems of efficiency in production costs during the studied period. It is possible to infer at least four possible explanations for the high level of inefficiency, namely: 1) Direct influence of the exchange rate on the price of herbicides, fertilizers and seeds (input); 2) Deficit in the static capacity of warehouses in Parana state; 3) Ratio between the variable "Financial Expenses" and the floating interest rate (SELIC rate); 4) Decrease in the sack price of the three commodities which coincides with a decrease in the efficiency of the crops.
