【 摘 要 】

A comparative analysis of changes in the level of energy inputs in crop production in select-ed farms in 2001, 2009 and 2010 was presented in the paper. The analysis indicates a wide variation of energy inputs in the particular farms. In the research period the level of such in-puts per 1 ha of cereal production did not changed (although, in the case of different types of cereals, the inputs were changing from –20% to +48%), while in the case of sugar beet, the inputs were decreased even more than 50%. In the case of energy inputs calculated per 1 ton of crops, the index was growing up from 6% (grassland), through 27-32% (cereals and potatoes) to 68% (sugar beet). There was one exception – corn silage – where the index grew up.
