Abstract. The studies aimed to determine the effect of microbiological preparations on growth parameters, disease resistance, and productivity of the common spring wheat variety Bashkirskaya 28 and the pea variety Pamyati Khangildina under model and field conditions. Field experiments were conducted in 2016 and 2020 on leached chernozem of the Cis-Ural steppe zone in the Republic of Bashkortostan. In model experiments, seed inoculation with Azolene preparation increased root growth of both crops by 17% and 18%, respectively, but it did not protect pea seedlings from phytopathogens. Batsispetsin BM stimulated the growth of wheat roots and shoots, which increased by 18% and 22%, respectively, relative to the control. It also stimulated the growth of pea roots by 15%. The preparation had a fungicidal effect on seed infection. Biological preparation Elena had no effect on the phytopathogenic complex of seeds of both crops and their growth rates. In field experiments, treatment with Azolene increased the number of productive stems and seeds of spring wheat by 27% and 22%, relative to the control. This increased the weight of seeds from one plant by 34%. In the option with Batsispetsin BM, the increase was 30%. The preparations Batsispetsin BM and Elena had the maximum impact on the productivity of pea in the experiment. They increased the number of beans on the plant, in comparison with the control, by 44% and 56%, respectively; the number of seeds increased by 49% and 53%; the weight of seeds increased by 22% and 28%. Azolene and Batsispetsin BM had the greatest protective effect on this crop. They reduced the spread of leaf pathogens to 35.1% and 36.2%, respectively, relative to 64.2% in the control. The most effective in terms of protecting spring wheat plants from diseases and increasing productivity were biological preparations Azolene and Batsispetsin BM; for pea, these were Batsispetsin BM and Elena preparations.
