    Sugar beet is the main crop commonly cultivated for sugar production in temperate regions of the World. Actual yields in main Central Europe producing countries are much lower, due to many limiting factors. Among them, nutrients supply is of great value, especially referring to efficiency of nitrogen, which is generally low. In the conducted study two methods of nitrogen application were compared (i) broadcast of calcium saltpeter and (ii) row application of the multicomponent fertilizer based on urea-ammonium-nitrate (UAN) solution. The basic amount of the applied N was 75 kg ha-1. The highest yields of both taproots and refined sugar were harvested on the plot receiving 75 kg N-1 as UAN liquid multicomponent fertilizer and 50% of the recommended P and K rates. The positive effects of row application of liquid N fertilizer on taproot and sugar yields were also corroborated by high values of indices of agronomic efficiency for both N as well as P and K. However this method of sugar beets fertilization has some possibilities, as indicated by still high contents of melassogenic substances.Burak cukrowy jest podstawowym surowcem do produkcji cukru w strefie klimatu umiarkowanego. W krajach centralnej Europy, w kt贸rych uprawia si臋 buraki cukrowe, aktualny poziom plonowania tej ro艣liny znacznie odbiega od potencjalnych mo偶liwo艣ci.
