Researches which lasted two years were carried out on stationary field trial, at Rimski Sancevi near Novi Sad, Serbia. In this trial were investigated eight fertilization variants with increasing doses of N, P2O5 and K2O. In spring before applying of N fertilizers, during vegetation and after extruding of sugar beet root, content of mineral N in the soil and its influence on yield and quality was investigated. Amounts of NO3-N in the soil in spring, before sugar beet sowing, in the year 2002, had significant influence on root yield and refined sugar yield. In the year 2003, which was dry, high correlation ratio, were gained between amounts of NO3-N in the soil and root quality parameters, but it was not significant between nitrogen amounts and root yield and refined sugar.
