The aim of this research was to assess accumulation and content of copper, zinc, manganese in main yield and by-yield of winter rape cultivated in conditions of different condensation of plants in field. In straw and seeds content of micronutrients was assayed and from the ratio of dry mass and determined Cu, Zn, Mn contents, the elements uptake by main yield and by-yield was calculated. Hybrid rape varieties accumulated significantly more copper in main yield and by-yield then the regular variety of rape. The increase of condensation of plants in field caused higher withdrawn of zinc and manganese with yield. More of these elements were withdrawn with rape main yield, however more copper with by-yield
