The article presents the results of the stochastic parametric approach of the production frontier estimate. The classical Cobb-Douglas production function is used as the basis of this estimate. The output-oriented measures of technical efficiency are derived on the basis of the production function estimate. The analysis is based on the data obtained from the data sets of the selected bundle of 5,604 agricultural cooperatives for the period of 1994-2000. The cooperatives are classified according to the acreage of agricultural land into six quantitative groups. The total production is considered to be an output and material and energy, services, labour costs and total assets represent the inputs. The achieved results of analysis indicate that the cooperatives operating on the larger scale of acreage reached statistically significant difference in the average level of technical efficiency. The average technical efficiency of the cooperatives with the acreage up to 500 ha is at its lowest value and represents 0.831. On the other hand, the cooperatives with the acreage over 3,000 ha reached the highest level of technical efficiency which is 0.941. The declining variability of technical efficiency amongst the larger cooperatives is evident. The average variability coefficient of technical efficiency of the smallest cooperatives is 14.5% and in the case of cooperatives with the acreage over 3,000 ha this coefficent is only 3.73%. The analysis showed that the differences of the average value of technical efficiency and also in the variability of technical efficiency in individual years are not statistically significant. Therefore, it is not possible to discuss certain given tendencies of the efficiency development in the period of time.
