The influence of application of increasing doses of Se (0.05 mg, 0.10 mg and 0.20 mg/kg) into soil in pot experiments, with NPK fertilization of spring wheat (Triticum aestivum, variety Banti), on the biomass yield (grain, straw, roots) and on Se accumulation was observed. Se in the form of sodium selenite and the NPK nutrients in the form of LAD-27, Ca(H2PO4)2 and KCl were applied. The average two-year results showed the expected indifferent effect of increasing doses of Se on the yield of wheat grain, straw and roots. The differentiated doses of Se into soil caused a significant increase of Se content in dry matter (dm) of grain, straw and roots of wheat. The highest content of Se (0.732 mg/kg in grain, 0.227 mg/kg in straw and 1.375 mg/kg in roots dm) was determined in the variant where 0.2 mg Se/kg of soil was applied. When applying the lowest dose of Se (0.05 mg Se/kg of soil) the content of Se was 0.155 mg Se/kg in grain. The Se content in individual analysed parts of wheat was increasing in the following order: straw - grain - roots.
