The aim of this study was to analyse technical efficiency and productivity changes in field crop farms in Lublin province. The assessment of technical, pure and scale efficiency of those farms during 2014-2016 was performed applying non-parametric method of Data Envelopment Analysis (DEA). The Malmquist indices were used to measure the efficiency and productivity changes. The field crop farms based on their economic size were divided into small, medium and large. The study showed that mean technical efficiency of small farms was 83 %, medium −81 % and large − 94 %. Technical inefficiency in Lublin region occurred due to pure technical efficiency rather than scale efficiency. It means that inefficient management practices had an impact on farm performance. Therefore, in order to increase competitiveness of Polish crop field farms, it is important to improve management practices. In the studied period the share of farms operating under increasing return to scale decreases with the growth of farm size. The improvement of efficiency of those farms could be achieved by increasing their size. The result indicates that 4 % of small, 14 % of medium and 9 % of large farms were operating under a decreasing scale efficiency, which means that those farms were operating above their optimal scale and could, therefore, increase their efficiency through size reduction. In all the farms, the average annual productivity changes were below 1. The decrease was mainly due to a technological detrition of 5, 6 and 38 % respectively for large, small and medium farms.
