Abstract

The paper depicts the research results of development of bacteria of the nitrogen cycle in the root zone of winter wheat plants (variety Sonechko) under the use of microbial preparation Polymyxobacterin and different doses of mineral fertilizers. It was established that split application of fertilizers at doses that do not exceed N60P60K60 and pre-sowing seeds bacterization had optimized the composition of microbial associations in the root zone of plants. The increase of fertilizers doses was followed by the negative changes in the number of bacteria of different functional groups.

Highlights

Nitrogen has the biggest impact on the among all major nutrient elements on the plant productivity and quality of the crop in all soil-climatic zones of Ukraine
The aim of given research was to study the number of bacteria involved in the nitrogen cycle in the root zone of winter wheat plants under the influence of fertilizers and such an important correction factor of microbial communities in the root zone of plants as a pre-sowing seeds bacterization
Analysis of the research results had shown that formation peculiarities of different groups of microorganisms of nitrogen cycle in the rhizosphere of wheat plants were similar throughout all years of study, had differ in absolute values
