Публікація Soybean growing under inoculation by Bradyrhizobium japonicum strains in the Forest-Steppe and Steppe zones of Ukraine(2026-03-03) Білявська, Людмила Григорівна; Biliavska, L. H.; Білявський, Юрій Вікторович; Belyavskiy, Y.; Кулик, Максим Іванович; Kulyk, M. I.; Тараненко, Анна Олексіївна; Taranenko, A. O.; Didovich, S.The strategic task of soybean (Glycine max (L.) Merr.) breeding today is to create highly adaptive cultivars that have a high level of genetic protection from biotic and abiotic environmental factors and are able to maximise the yield potential in combination with a high grain quality. The use of inoculants is an environmentally safe measure that can significantly increase the soybean yield and reduce the level of plant damage by pests. The aim of the experiment was to evaluate the biological inoculants based on Bradyrhizobium japonicum strains under different cultivation conditions and dry-resistant soybean cultivars ‘Almaz’ and ‘Antracite’. B. japonicum strains 634b for the ‘Almaz’ were the most effective in the Forest-steppe, as the yield increased by 0.11 t ha-1 compared to that of the control treatment. At the same time, the yield increased by 0.05 t ha-1 due to the application of B. japonicum strains М8. Under these cultivation conditions, for the ‘Antracite’, the B. japonicum strains М8 provided the greatest growth of yield (increased by 0.23 t ha-1 compared to that of the control) and by 0.14 t ha-1 when the B. japonicum strains 634b were used. On the average, over the experimental years, soybean cultivars in the Forest steppe had a much higher yield (2.70–2.88 t ha-1) compared to that of the Steppe (1.28–1.88 t ha-1). Treatment with the B. japonicum strains 634b significantly increased the yield for the ‘Almaz’ and ‘Antracite’ in the Steppe. In the Forest-steppe, the treatment with B. japonicum strains 634b was more effective for the ‘Almaz’ and the one with B. japonicum strains М8 for the ‘Antracite’. Quantitative symbiotic indices of soybeans were higher in the treatment with B. japonicum strains 634b for the ‘Almaz’ in the Forest-steppe and Steppe. In the Steppe, the application of B. japonicum strains М8 was more effective for the ‘Antracite’.Документ The results of study of ecological stability and plasticity of Ukraian soybean varieties(Annals of Agrarian Science. – Volume 15, lssue 2, 2017) Biliavska, L. H.; Білявська, Людмила ГригорівнаAbstract The article gives analysis of practical value of soybean varieties according to productivity and ecological plasticity in different climatic provinces in Ukraine. Ecological estimation of soybean varieties using method of Eberhart S.A. and Rassel W. K. has been made. Variety plasticity and adaptive potential have been defined on the basis of this estimation. It has been established that varieties Almaz and Diona were the best varieties according to the results of ecological variety studies. The most favourable regions for cultivation of up-to-date soybean varieties have been chosen. Variety Almaz has been defined as the most intensive and plastic soybean variety (average yield in years was 2.66 – 2.93 t/hа). Varieties Antratsit and Ametist also have shown high plasticity. Varieties are recommended for cultivation in steppe and forest-steppe in Ukraine. The higher numerical value of coefficient the more variety reaction on improving cultivation conditions. Thus, varieties with higher regression coefficient and lower mean square value have optimal indicators. High sensitivity of some varieties to unfavorable cultivation conditions offen narrows area of these varieties distribution and limits their general distribution. On the basis of examination of soybean varieties in different regions we can predict genetically specific degree of yield stability (adaptation to cultivation conditions).Публікація Variability of soybean varieties in terms of yield components and yield in the conditions of the Forest-Steppe of Right-Bank Ukraine(2026-01-18) Mazur, O.; Mazur, O.; Zayka, K.; Didur, I.; Biliavska, L. H.; Білявська, Людмила Григорівна; Tsyhanskyi, V.; Verheles, P.The article presents the results of long-term studies of soybean variety variability in terms of valuable economic traits (yield components) and yield under different hydrothermal growing conditions. Varieties that ensured high stability of yield components were identified using mathematical and statistical analysis methods. The highest repeatability coefficients for the number of productive nodes were observed in the Desna variety – 0.82, with a coefficient of variation of 12.7% and 16.1 productive nodes; in the Bilyavka variety – 0.81, with a coefficient of variation of 12.4% with an average value of 16.7 units. The variability of the yield level during the years of research was high, with the repeatability coefficient ranging from 0.55 to 0.75, which is quite natural given the large number of formative traits that contribute to its determination. The highest repeatability coefficients were observed in the varieties Femida – 0.75, coefficient of variation – 10.7%, and yield – 1.88 t/ha; Amethyst – 0.73, coefficient of variation – 11.4%, yield – 1.88 t/ha; Vezha – 0.72, coefficient of variation – 11.4%, yield – 1.89 t/ha. It should be noted that these varieties were distinguished by high values of repeatability coefficients for the weight of 1.000 seeds, in particular, Femida – 0.91, Ametist – 0.93, Vezha – 0.80; as well as for the number of productive nodes, pods, and seeds: Femida – 0.69; 0.52 and 0.55, and Vezha – 0.68; 0.56 and 0.57, respectively. Thus, ensuring a stable level of soybean yield is determined by the formation of stable indicators of the elements of the soybean yield structure of each variety in particular.
