The article contains the results of winter wheat cultivation in the forest steppe of the Middle Volga region, as a result of the use of microelements. The object of research is winter soft wheat of the variety Saratovskaya 17. An empirical relationship was obtained between the options of using microelements (the first option is seed treatment; the second option is seed treatment in the combination with foliar top dressing at the end of the tillering phase – the beginning of shooting; the third option is only foliar top dressing) with the winter wheat yield for soil and climatic conditions of the region in question. The linear regression equations have been presented, obtained on the basis of correlation and regression analyses, which makes it possible to determine the analytical relationship between the ways of using microelements-synergists of manganese, zinc and the yield in the technology of cultivating winter wheat. At the same time, the mathematical processing of the data showed that the methods of using trace elements – manganese and zinc reliably influences the yield of winter wheat.

The task of improving the quality of agricultural tools by improving the technological processes of their functioning, taking into account the kinematic features of the combined impact of working elements of tools on the soil environment is important from a scientific and technical point of view. To form the required structure and density of the soil layer at the depth of sowing, a hammer perforated tillage roller (HPTR) has been developed. The study aim is to improve the quality of post-sowing compaction and structuring of the soil layer in the seed location zone based on the development of an innovative design of HPTR that combines different effects on the treated environment. The object of research is the kinematic mode of operation of the HPTR, equipped with cylindrical hammers installed at the ends of the rod, which, in turn, are radially and pivotally installed on the axis of the gunFeature of offered HPTR is the excitation of hammer vibrations, which changes the kinematic parameters of the tillage tool as a whole. Lagrange equations of the second kind are used to describe the process of HPTR operation, which is represented as a system of material objects with several degrees of freedom. The conducted studies revealed the periodic nature of changes in the strength of the impact of HPTR on the soil. The obtained equations allow us to determine the features of the HPTR movement at different masses of a hollow perforated cylinder and cylindrical hammers. This is of great importance for increasing the efficiency of soil bolster destruction and creating the soil structure recommended for winter crops sown in the Middle Volga region.
