Sugar beet forms a crop of small number of plants as compared to cereals or pulses. Well developed root is a used part of plant and its physical parameters determine the magnitude of yield. Root yield structure is important for both yield and its quality per unit area. The fraction of big roots is decisive in the view of yield, while physical features of roots, associated with chemical ones, affecting technological value of roots determine sucrose yield per 1 ha. The aim of the paper was to follow root structure forming in the crop during vegetation and to show yield forming effect of nitrogen upon the contribution of individual fractions, especially that of big roots
