In the field experiment out in 1999 on grey podsolic soil, the effect of four potassium doses (Kamex gran) on background of two nitrogen fertilization levels (ammonium nitrate) was estimated. At dose of 320 kg K2O/ha clear reduction of beet emergence was observed. Increase of N dose up to 180 kg N/ha contributed to significant increase of leaf yield, alpha-NH2-N content in roots, whereas sugar content decreased. Potassium doses up to 240 kg K2O/ha caused significant increase of sugar yield, sugar and potassium content in roots. Root and leaf yield increased significantly at dose of 80 and 160 kg K2O/ha
