Winter wheat is the most important grain crop in Russia, in recent years it occupies a quarter of the grain wedge. The research was carried out in 2014-2019. in a long stationary field experience of the Department of Agriculture of the Tambov Scientific Research Institute of Agriculture - a branch of FSBSI "I.V. Michurin Federal Scientific Center" with differentiated use of mineral fertilizers based on optimization of nitrogen nutrition using liquid mineral fertilizers Megamix. The purpose of the work is to study the effect of various doses (N 30 and 60 kg/ha d.) of methods and timing (foraging, tube entry, coloration), application of Megamix macro and micro fertilizers (forging) on winter wheat yield in the Tambov region in a long stationary field experience. This article presents the results of scientific research for the first rotation of crop rotation conducted on the typical chernozem. It was revealed that the yield of winter wheat ranged on average from 3.34 tons/ha on the version without fertilizers (1), to 4.60 tons/ha on the version N40P40K40 + N60 (in spring) + N30 (output to the tube (6). All options with fertilizers showed the largest, reliable increase in yield. It was established that when using traditional mineral fertilizers and liquid mineral fertilizer Megamix, there is an increase in yield relative to the option without fertilizers. The lowest increase relative to control (1) was shown by variant N40P40K40 (2) - 0.36 t/ha. The studies revealed the feasibility of the joint use of traditional mineral fertilizers and liquid mineral fertilizer Megamix on winter wheat in the conditions of the Tambov region on a typical chernozem
