The cultivar specifics in relation to mineral nutrition are the point of these investigations with aim to determine differences among genotypes in relation to presence of some microelements (Fe, Mn, Zn, and Cu), considering their practical importance. The investigation was carried out in field conditions on acid soil (pHKCl=4.26). Six wheat cultivars (Takovcanka, Studenica, KG=56, Lazarica, KG=100, Toplica) were examined with next fertilizing variants: control (without fertilizing), NPK (500 kg/ha); N (75 kg/ha) + CaCO3 (2.0 t/ha); NPK (500 kg/ha) + CaCO3 (2.0 t/ha) and NPK (500 kg/ha + CaCO3 (2.0 t/ha) + cow manure (35 t/ha). It was concluded that traits of soil, species and genotypes are important factors influencing adoption of microelements by wheat plants. So, decreasing of microelements (Fe, Mn and Zn) content was observed in NPK as like in liming variants, but nor below values plants would suffer because of their deficiency. On the contrary, deficiency of Cu in variants NPK + CaCO3 and NPK+CaCO3+humus, in some cultivars was registered that can cause morphological and anatomical changes in plants.
