Abstract. The purpose of the research was to study the effect of foliar feeding with agrochemical preparations on the yield and quality of spring common wheat grain. The work was performed in 2018–2019 in the forest-steppe zone of the Omsk region. A two-factor field experiment (2 x 5) was conducted in a five-field grain-fallow crop rotation. The forecrop was bare fallow. The experimental design provided for the study of the following treatments: mineral fertilizers (factor A) – without fertilizers, application of P90 to the fallow field; agrochemical preparations (factor B) – without treatment, MicroMix, Cu EDTA, grain Biostim, Lignohumate. Spring wheat crops were sprinkled in the tillering phase with solutions of preparations in the concentrations recommended by manufacturers. The soil in the experimental site was meadow medium-thick medium-humus heavy loamy chernozem. Agricultural technology in the experiment was zonal. Priority attention should be paid to preparations MicroMix and Cu EDTA. Applying P90 foliar feeding with these preparations provided an increase in wheat yield, in comparison with the option without foliar feeding, by 0.51 t/ha and 0.44 t/ha of grain respectively. The yield of spring common wheat increased due to an increase in the length of the ear, the mass of a thousand grains, and productive tillering. The protein content and yield per 1 ha were the highest in the same options – 12.9% and 13.0%, 407.6 kg/ha and 401.7 kg/ha, respectively. Foliar top dressing of spring wheat with MicroMix and Cu EDTA preparations increased the agronomic payback of mineral fertilizers by 12–37%, in relation to the background without top dressing. We did not register any contamination of crop products with heavy metals when using all the studied preparations.
