S., Rudenok O. O., Sviatetskyi V. A., Kramarenko K. E. The effect of biological fertilizers and microelements on soybean yield. Актуальні напрями та проблематика у технологіях вирощування продукції рослинництва: матеріали V міжнародної науково-практичної інтернет-конференції (м. Полтава, 25 листопада 2025 р.). Полтава: ПДАУ, 2025. С. 97-100. ISBN: 978-617-8466-56-5The article investigates the combined influence of biological fertilizers and essential microelements on the formation of soybean (Glycine max L.) yield. The author evaluates the efficiency of integrating bacterial inoculants (nitrogen-fixing strains) with the application of key micronutrients such as boron, molybdenum, and cobalt, which play a crucial role in enzymatic processes and symbiotic activity. The research highlights how this integrated nutrition system stimulates early plant development, enhances the nitrogen-fixing capacity of root nodules, and improves the chlorophyll content in leaves. The study provides data on the positive correlation between the application of chelated microelements and yield structure parameters, including the number of pods per plant and seed weight. The findings substantiate that the synergy of biological agents and micronutrients not only increases grain yield but also enhances the protein content in seeds, offering a cost-effective and environmentally friendly approach to soybean cultivation.enSoybeanbiological fertilizersmicroelementsyieldnitrogen fixationmolybdenumboronseed qualityinoculationsymbiotic activityArticle
