Over a three-year small-plots field experiment the stimulating effect of foliar application of vermisol together with nitrogenous nutrition within the framework of productive and qualitative winter wheat fertilization was investigated. Five experimental variants were included in the trial: control unfertilized variant, two experimental variants of productive fertilization (variants 30N and 30N+V) and two variants of qualitative fertilization (variants 10N and 10N+V). The best effect on grain yields was achieved by simultaneous application of vermisol and nitrogen within productive fertilization (variant 30N+V) when the increase of grain yield represented 0.91 t/ha (13.6 %) compared with unfertilized control variant and 4.7 % compared to single nitrogenous nutrition (variant 30N). As a consequence of vermisol application intake of individual nutrients by plants as well as their uptake per hectare increased as follows: nitrogen by 10.3 %, phosphorus by 4.6-5.3 %, potassium by 1.9-6.3 %, calcium by 2.3-4.3 % and magnesium by 4.8-6.9 %. At the same time the content of crude protein and wet gluten in winter wheat grain increased by 4.9-8.2 % and 2.1-4.1 %, respectively. The other qualitative characteristics of wheat grain were not affected by vermisol application
