Field experiments on spring wheat Banti and Eta cultivars at in low copper soil abundance showed the pre-sowing fertilization with this microelement at dose 5 kg·ha⁻¹ increased grain yield (by about 0.51 and 0.20 t·ha⁻¹). The higher grain yield (by about 0.37 and 0.25 t·ha⁻¹) was also obtained at zinc fertilization dose 5 kg·ha⁻¹. There was more advantageous effect of grain yield at manganese, manganese...
