Abstract: The study was based on the experiment carried out at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry in Central Lithuania on an Lightloam, Endocalcari-Endohypogleyic Combisol during 2012, in order to figure out the effect of different configurations of complex fertilizers on sugar beet yield and quality parameters. "Ernestina" is the type of sugar beets selected for testing. Different configurations of complex fertilizers in the background of nitrogen fertilizers (N120 and N150 kg ha-1) were used for testing as well as the plants were additionally fertilized with liquid boron fertilizer through the leaves 1 l ha-1 during the growing season. It was found that when sugar beets were fertilized with complex fertilizers, significant yield was obtained (6.93 to 13.42 t ha-1). The NPK 16-16-16 fertilizers N150 rate increased the sugar beet yield the most efficiently (82.19 t ha-1). Based on the test results it can be stated that all complex fertilizers used in the test increased the yield of white sugar (0.86 to 2.1 t ha-1). The largest yield of white sugar (13.35 t ha-1) was obtained from plants fertilized with NPK 16-16-16 fertilizers N150 rate. Concentration of alpha-amino nitrogen in sugar beet roots did not change while they were fertilized using NPK 12-11-22 + 2.5 and Na 5-10-25 NPK complex fertilizers
