    Soybean (Glycine max L.) is one of the most sought-after legumes on the global market due to its high demand in the feed, food, and industrial sectors. Climate change necessitates the implementation of technological innovations to enhance plant resistance to adverse growing conditions. The aim of this study was to investigate the effect of pre-sowing seed treatment of soybean with the bacterial preparation Profix, the phytohormone based preparation Violar, as well as their combined application through seed inoculation and crop spraying during the bud formation–bloom phase, on the development and productivity of soybeans under an organic farming. To examine the dynamics of leaf surface area, photosynthetic pigments, malondialdehyde and proline levels, and their relationship with yield, the ANOVA-Tukey test and principal component analysis were employed. The field experimental results showed that pre-sowing seeds treatment with the Profix inoculant, the phytohormonal preparation Violar, and their combined application contributes to an increase in leaf surface area, an enhancement in the content of photosynthetic pigments, a reduction in malondialdehyde levels, and an increase in proline content in soybean plant. These physiological improvements ultimately led to average soybean yield increases of 12.3%, 19.6%, and 29.2%, respectively, despite adverse weather conditions 2024. These results demonstrate the effectiveness of integrating bacterial and phytohormonal seed treatments as a sustainable and innovative approach to enhancing soybean productivity under organic farming conditions.

    Physiological and biochemical aspects of pre-sowing treatment of soybean (Glycine max (L.) Merr.) seeds
    (2026-03-03) Chaika, T.; Короткова, Ірина Валентинівна; Korotkova, I. V.; Шевніков, Микола Янаєвич; Shevnikov, M. Ya.; Ляшенко, Віктор Васильович; Liashenko, V. V.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Horbenko, O.
    Soybean is one of the most in-demand crops, with its production increasing; however, climate change affects yield, necessitating the application of biopreparations to enhance plant resilience to stress conditions. This study aimed to investigate the effects of pre-sowing seed treatment with an inoculant and a phytohormonal preparation on the physiological and biochemical parameters of soybean plants and their yield under organic farming conditions. A field study conducted in 2022 2024 examined the impact of pre-sowing seed treatment with the inoculant Legume Fix and the phytohormonal preparation Violar on leaf area, proline content, malondialdehyde levels, photosynthetic pigments, and yield under various weather conditions in an organic farming system. It was established that pre-sowing seed treatment increased leaf area by an average of 13.4% with Legume Fix and by 19.3% with Violar. It was established that the highest increase in proline content (as a protective response) was observed in the hot conditions of 2024, with seed treatment using Violar (41.2%) and Legume Fix (26.5%). Over the study period, the lowest MDA concentrations in soybean plants were recorded following seed treatment with Violar and Legume Fix, averaging 7.57 and 9.33 µg/g fresh weight, respectively, which was 37.4% and 22.9% lower than in the control plants. Treatment with Violar resulted in an increase in Chl a, Chl b, and total Chl (a + b) content by an average of 18.9%, 13.3%, and 17.2%, respectively, compared to the control, while inoculation with Legume Fix led to increases of 7.4%, 3.4%, and 6.2%, respectively. Pre-sowing seed treatment with Legume Fix and Violar resulted in a higher yield than the control plants, with average increases of 13.2% and 20.6%, respectively. The obtained results may be recommended for organic farming to enhance crop yield.
