Objective. To determine the influence of complex nanocomposite bacterial preparation Azohran on plant growth and development and buckwheat productivity by simulation of organic production. Methods. Nanocomposite complex bacterial preparation Azohran was produced on the basis of interaction of strains Azotobacter vinelandii IMB B-7076 and Bacillus subtilis IMB B-7023 with bentonite nanoparticles. The study of the influence of the product on plant growth and development and the yield of buckwheat of Sin 3/02 variety under simulation of organic production was carried out on the experimental field of the National Scientific Center “Institute of Agriculture of the NAAS”. Results. It has been established that presowing bacterization of buckwheat seeds with nanocomposite complex bacterial preparation Azohran significantly stimulates plant growth and development. The use of this product was accompanied by an increase in the area of the leaf surface of the plants. In the control variant, the area of the leaf surface during the flowering phase was 11.6 thousand m2/ha, and under the use of Azohran this parameter increased to 14.9 thousand m2/ha, or by 28.5%. During the cultivation of buckwheat without bacterization, the area of assimilation surface from the flowering phase to maturation decreased 2.3–2.5 times, however, the use of presowing bacterization slowed the die-off of leaf blade — their area decreased only 1.7 times during the maturation period. The content of nitrogen, phosphorus and potassium compounds increased significantly in bacterized plants. The crop yield increased to 1.08 t/ha (by 22.7% compared to the control). The sowing of buckwheat seeds bacterized with Azohran in the soil against the background of straw plowing provided a yield increase of up to 1.3 t/ha (30%). Conclusion. Presowing bacterization of buckwheat seeds with the nanocomposite complex bacterial preparation Azohran significantly improves plant growth and development and increases crop productivity by 22.7-30%.
