Influence of microelements-synergists on the yield and quality of winter wheat grain

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.
