A long-term experiment was carried out from 2002 to 2004 in order to compare the yields of winter wheat, spring barley and pea grown in rotation and using different tillage methods as follows: 1) conventional tillage (CT); 2) minimum tillage (MT); 3) no tillage (NT). The results were evaluated from the economic and energetic points of view. MT with possible incorporation of straw and post harvest residues was shown to be the cheapest method. Catch cropping used with MT was the most expensive. The NT technology was supposed to be the cheapest one, but the costs often increased due to the necessity to use more expensive pesticides. The highest demand for total output of supplementary power was calculated for winter wheat with the CT technology; the lowest one for pea with the CT technology. The best utilization of supplementary energy inputs calculated was for winter wheat.
