Abstract
The aim of the research was to determine the influence of fertilization with pelleted organic fertilizers (Phenix and Bio-rex) and mineral fertilizers and its combination on yield and technological quality of sugar beet root. Investigations were carried out on antropogenized eutric brown soil, on slightly luvic loam in Zagreb during 2012 – 2014. The research included six fertilization variants: control – unfertilized; Phenix 0.6 t/ha; Bio-rex 1.0 t/ha; mineral fertilizer (NPK = 113:190:270); mineral fertilizer (NPK = 83:160:240) + Phenix 0.6 t/ha and mineral fertilizer (NPK = 83:160:240) + Bio-rex 1.0 t/ha. Weather conditions, especially precipitation amount and distribution, had significant influence on yield and technological quality of sugar beet root. Significantly higher root and sugar yield were obtained with mineral fertilizers and combination of mineral and organic fertilizers. Fertilization with organic and mineral fertilizers had no effect on sugar content in root but the highest sugar utilization of digestion was achieved applying the organic fertilizers Phenix and Bio-rex
