The article presents the results of long-term research aimed at studying the influence of mineral nutri-tion elements in the technology of growing winter and spring wheat in the conditions of Ulyanovsk region on grain yield and quality, taking into account the soil resources of the region. The winter wheat varieties Bazalt, Saratovskaya 17 and spring wheat – Simbirtsit, registered in Ulyanovsk region, were selected as research ob-jects. Pre-sowing seed treatment and foliar treatment of plants with zinc and manganese sulfate solutions were carried out taking into account the low content of these elements in the soil (Mn ˂ 30 mg/kg; Zn 0.1-0.2 mg/kg; S 0.3-1.3 mg/kg) and their great importance for plant metabolism. This technological method helped to increase the field germination of winter wheat plants of the Bazalt variety with natural soil fertility by 4.5-5.3 % and of spring wheat plants of the Simbirtsit variety with mineral nutrition by 5.2-7.3 %. The yield of winter wheat of the Bazalt variety (3.54-3.75 t/ha) increased by 12.7-22.0 %, that of spring wheat (2.51-2.65 t/ha) – by 13.7-20.3 % on the background without fertilizers. The yield of the winter wheat variety Saratovskaya 17 was 5.46-6.06 t/ha in the variants and the effect of the treatment was less significant. The indicators of pro-tein content in grain and gluten mass fraction did not differ significantly in the variants of the experiment, but the quality of gluten increased in the variants with the joint application of ZnSO4 and MnSO4 on the back-grounds with mineral fertilizers.
