This paper attempts at defining and comparing winter and spring barley economic effectiveness. The analysis was based on long-term crop rotation experiment and grain prices in the second quarter of 2003. The profits obtained per area unit were 88.7% higher for winter barley. The profitability ratio for winter barley reached 1.70; and for spring barley – 1.3. Smaller differences were found for energy efficiency index; 2.94 for winter barley and 2.37 for spring barley. The comparative analysis of winter and spring barley production on the stand after potato shows a higher energy efficiency and more favourable economic results for winter barley.
