Abstract

Development of microbiota management methods to optimize plant biological productivity is a promising area of modern agriculture. The aim of this study is to analyze changes in the number of various ecological and trophic groups of microorganisms in the rhizosphere and evaluate the productivity of winter triticale using microbial supplements. The study was conducted from 2021 to 2023 in Leningrad region on Bilinda winter triticale plants. The experimental scheme included the following options: no inoculation (control), Agrofil (Agrobacterium radiobacter, strain 10), Mizorin (Arthrobacter mysorens, strain 7), Flavobacterin (Flavobacterium sp., strain 30), Rizobact RZhF (Corynebacterium sp., strain PBT 7), MZhF (Enterobacter sp., strain PBT 3), FZhF (Pseudomonas sp., strain PBT 4), and N100. Seed inoculation was carried out on the day of sowing with a suspension based on preparations with a titer of 5×109 CFU/ml and a rate of 1 l per 1 ton of seeds. Soil samples were taken from the rhizosphere zone during tillering, booting and milky ripeness phases. The soil of experimental field was sod-podzolic medium loamy. Meteorological conditions during the study years varied in moisture and temperature, but were favorable for grain formation and maturation. The highest numbers of ammonifiers and actinomycetes were recorded with Flavobacterin and Rizobact FZhF brand, while cellulose-degrading microorganisms were active with Mizorin and Rizobact RZhF brand. High numbers of microscopic fungi were observed in the RZhF and MZhF Rizobact variants. The highest number of phosphate-mobilizing microorganisms was recorded with Rizobact FZhF. All treatments showed an increase in the total number of oligotrophs compared to the control. The highest number of spikelets, grains and their weight were observed in Mizorin treatment. The increase over the control was 9.8%, 27.3% and 33%, respectively.
