In practice the heavy macronutrient fertilization is usually applied for rape while the micronutrient application is not a routine procedure. Covering of rape requirement for boron is especially important, considering its influence on generative organs' formation, developing of siliques and seeds. Boron deficiency leads to decrease of seed yield even by 80%. At commonly occurring B deficiencies in domestic soils, boron fertilizer application to rape appears tobe necessary. It is also important to consider the rape as a Mo-sensitive plant. The effectiveness of molybdenum application for rape has been stated in investigations, on acid soils, with low Mo availability for plants. Stated significant response of rape seed yield to copper fertilization and its considerable uptake with yield, indicate also some sensitivity of the crop to Cu deficiencies. Copper application is advisable procedure on heavier soils, rich in organic matter, where Cu availability for plants is limited. On the soils showing pH>6,5 the supply of manganese is also justified. High Zn nutritional needs of rape are covered by domestic soil resources.
