In the conditions of the Republic of Belarus there were presented the results of the research which show the influence of different forms of micronutrient fertilizers on the yield and quality of spring wheat (Triticum aestivum) variety Daria. It was revealed that on the background application crop fertilizing N60P50K135 foliar UAN solution enriched with micronutrient fertilizers copper sulfate, ADOB-Cu, ekolist Mono copper, akvarin, as well as growth regulator gidrogumin, increases the yield of spring wheat by 2,1-3,3 centners per hectare. It also increases the content of crude protein in grain. The economic evaluation of application of new forms of trace element fertilizers is given. In average in 2008-2010 experimental years the combined application of UAN (N40) chelated forms of micronutrient fertilizers ADOB-Cu and ekolis against the background of N60P50K130 provided the maximal yields – 10.4-10.5 yield increases, respectively. In case of use of copper sulphate, hudrohumine, akvarin the yield increases were respectively 9.6; 9.8; and 9.3 centner/ha.
