This article presents the results of a study on the development of sowing qualities and yield properties of soybean seeds depending on pre-sowing treatment with microbiological fertilizers. The purpose of this study was to justify the use of pre-sowing treatment of soybean seeds through inoculation with microbiological fertilizers and to identify an inoculant that ensures high sowing qualities and yield properties under local soil and climatic conditions. The data presented indicate that pre-sowing treatment of seeds with microbiological preparations has an impact on the preservation and survival of plants. When evaluating various pre-sowing seed treatment options, it was found that a more stable agrocenosis formed in the variant where inoculation was carried out with a mixture of Azotovit (2 l/t) and Fosfatovit (2 l/t) microbiological fertilizers. As a result, it was found that pre-sowing treatment of soybean seeds with Azotovit and Fosfatovit microbiological fertilizers promotes the formation of offspring with a higher 1000-seed weight and germination energy by mother plants, but does not affect the yield properties of seeds. It was shown that when soybean seeds were inoculated with a mixture of Azotovit and Fosfatovit, a synergistic effect was observed, expressed in higher indicators of 1000-seed weight formation by mother plants, germination energy, and yield properties in the subsequent generation of seeds.
Keywords: variety, soybean, sowing qualities, yield properties, seeds, plant survival, plant preservation.
