Abstract
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.
Highlights
The yield level is an integral indicator combining the realization of the yielding capacity potential inherent in the plant genome with the state of environmental factors and modern technological methods used as a means to bring out the metabolic capabilities of a particular cultivated crop more fully.Under the conditions of the forest-steppe of the Middle Volga region, when cultivating winter wheat, in addition to moisture supply, the level of mineral nutrition is of great importance
Microelements are an important part of it, whose role in plant nutrition is great. Their deficiency in the soil leads to disruption of important biological processes in plants
We used the data on the yield of the experimental crop for 5 years for our analysis (Table. 1.)
Summary
Under the conditions of the forest-steppe of the Middle Volga region, when cultivating winter wheat, in addition to moisture supply, the level of mineral nutrition is of great importance. Microelements are an important part of it, whose role in plant nutrition is great. Their deficiency in the soil leads to disruption of important biological processes in plants. Microelements are contained in extremely low concentrations, have a significant effect on the growth processes of development, they improve metabolic processes, stimulate photosynthetic activity of plants, increase the yield and product quality. Most of them are cofactors of enzymes and contribute to an increase in the activity of oxidoreductases and hydrolases depending on those metabolic processes that have developed during their evolution [1–6]
