摘要

The aim of this work was the energetic evaluation of different cultivating Technologies of the spring barley. A stationary field experiment was carRied out during 2004 - 2007 at the Experimental base of the Slovak University of Agriculture in Dolná Malanta. The following crop rotation system was used: winter wheat, pea + intercrop: white mustard, grain maize, spring barley with under cropping of clover. The tillage treatments were as follows: B1 – conventional tillage, B2 – reduced tillage and B3 – minimum tillage. The scheme of fertilization was as follows: 0 – without fertilization; PH – balanced fertilization to expected yield; PZ – balanced fertilization with incorporation of remains after harvest. The energy efficiency was calculated for the energy output. Incorporation of intercrop and clover led to the increase of energy efficiency of crop rotation and strengthening energetic potential of soil.
