The article presents the results of researches of 2016-2018 on the study of the effect of seed treatment before sowing with bacterial agents Risoline and Graundfix, the use of insecticidal fungicidal bacterial preparation and complex microfertilizers containing chelate-shaped elements on gray forest soils on the individual productivity and yield of pea varieties. The experimental data obtained can be used in the development of a system for the application of bacterial drugs on pea varieties, on

On average, during the years of the study, it was found that the number of beans, seeds and the mass of 1000 seeds of seedlings largely depended on the factors that were put into study. The maximum number of beans in the Gregor variety was 4.72 pp. / Plant, the number of seeds was 19.58 pp. Per plant, the largest seed weight per plant was 4.10 g, the weight increase of 1000 seeds was 233.65 on variants using pre-sowing treatment of seed material with the Risoline + Gradeffix against the background of mineral fertilizer N30P60K60 and the post-root nutrition of crops in the phases of 3 true leaves of the fertilizers Gumat List + Ultrafit and fertilizer budding Gumat Sheet + Ultrafit + LF-Bean + LF- Bohr 140. It was noted that the maximum yield of pea grains 3,55 t/ha in the Ataman and Gregor – 4.06 t/ha was noted during pre-seed treatment and nutrition and protection systems.
