The purpose of the research is to study the main econometric methods of efficiency measurement — Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA), and their practical application for measuring the technical efficiency in crop production. The results are new and crucial due to the fact that DEA and SFA are utilized for obtaining mixed measurements of efficiency. Based on the proposed approach, we evaluate technical efficiency in crop production of 100 farms at Kulunda steppe (Altai Region) for the last five years. Within the research, some significant factors are revealed that affects the technical efficiency in crop production at Kulunda steppe. Some of them are: size of sown area, share of revenue from crop production, yield of grain and leguminous crops, number of workers employed in a farm, age of a farm head, and type of ownership. The analysis of technical efficiency in crop production at Kulunda steppe leads to the following conclusions: crop production rentability of 48–62 % under the current economic conditions is available due to yield growth of grain and leguminous crops by 2–3 center per ha with the revenue growth of 0.85–1.36 thousands of rubles per ha, and decreasing of production costs.
