In a one-factor field experiment the size and structure of energy inputs incurred for cultivation of the hybrid rye and the size of the energy effectiveness index were compared. The size of the accumulated energy inputs was not varied in case of the compared cultivation systems, it mainly depended on the accumulated energy inputs brought in the form of materials (ca. 85%). The use of non-ploughed cultivation required energy inputs brought in the form of fuel (by 9.3% in comparison to ploughed cultivation) and in the form of aggregates (by 2.3% in comparison to ploughed cultivation). The applied cultivation systems did not differentiate the energy effectiveness of production and the determined difference was approx. 1% in both cases.
