The efficiency of new forms of selenium-containing nitrogen fertilizers for optimi¬zation of selenium content in grass stand in the field experiences with perennial cereal grasses cultivated on sod-podzolic light loamy soil has been studied. It is found that selenium-containing nitrogen fertilization under perennial cereal grasses has not substantial effect on yield increase but promotes the accumulation of this element in cereal grasses harvest up to the optimum concentration by introduce selenium in KAS in doses 0,05 and 0,15 kg/ha and in urea - 0,15 and 0,35 kg/ha
