Abstract

Objective. Determine the efficiency of bacterization of millet seeds with a complex nanocomposite bacterial preparation Azohran (Azohran-nano) depending on the growing conditions of the culture; establish the effect of mineral fertilizers in combination with a biopreparation on the productivity of agrocenoses. Methods. Field experiment (to assess the influence of the studied factors onthe growth and development of plants and millet yield), measuring- and weight-based, economiccalculations, statistical. Results. During three-year observations, a positive effect of mineral fertilizers and pre-sowing inoculation of millet seeds with Azohran-nano on plant height, plant weightgain, heads weight and crop productivity was established. The height of plants in the variant withbacterization of seeds when growing millet without fertilizers in the stalking phase was higher by5.6 % than the corresponding parameters of the control variant and with the concomitant use offertilizers and bacterization this figure increased to 8.1 %. Seed inoculation had a positive effect onthe weight of millet heads.The efficiency of bacterization in the cultivation of the crop at the background without fertilizers was 6.3 %, and when the plants were cultivated using nutrition with nitrogen during the growing season, this figure increased by 11.5 %. The highest yields of millet were reported for seedtreatment with Azohran-nano. Yield in the control variant was 3.75 t/ha, while after the bacterization of seeds with the preparation, crop productivity increased by 16.5 % Upon the interaction between mineral fertilizers with nanocomposite preparation, parameters increased by 19.9–28.6 %.Under the influence of pre-sowing inoculation of seeds, the cost of 1 tonne of grain decreased, andthe net operating profit increased. Conclusion. The use of nanocomposite complex of the preparation Azohran-nano in millet cultivation technologies promotes the growth and development ofplants, increases crop productivity and is a highly efficient agricultural measure.
