Efficient use of inputs directed towards decreasing input levels is conducive to the concept of sustainable agriculture. Reduced levels of some inputs may contribute to the decrease in natural environment contamination. The DEA (Data Envelopment Analysis) method was applied to measure the relative efficiency of farms and to setting up input target values f or inefficient objects. Efficiency of farms was analysed with respect to the market plant production on a sample of 10 farms owned to the Treasure Agency for Agricultural Property, Branch in Poznań (Poland). The data showed that 4 farms were technically inefficient. The mean technical efficiency within these farms was 82.9% (0.829). The technical efficiency interval for this subgroup ranged from 80.2% (0.802) to 87.1% (0.871). Contribution of pure technical inefficiency to the total inefficiency level was seven-fold that for scale effect. Three distinct groups of farms were identified in relation to the unit direct costs and efficiency coefficient. The results suggest that farms not fully efficient may improve their efficiency mainly due to the cost reduction in cultivation activities, pesticide application and harvesting.
