This study evaluated the effects of mineral fertilization, a humic-based biostimulant, and a titanium-containing micronutrient preparation on the growth, biomass yield, and economic performance of Miscanthus & times; giganteus grown on acidic low-fertility soil in Western Ukraine from 2022 to 2025. A repeated-measures mixed-model analysis showed significant effects of treatment, year, and treatment & times; year interaction for the main growth and productivity parameters, indicating a year-dependent fertilization response. Integrated fertilization improved plant height, shoot formation, dry biomass yield, and biofuel output compared with the unfertilized control. The highest mean dry biomass yield was obtained with N30P30K30 + Black Jack, reaching 16.43 t ha-1 and exceeding the control by approximately 40%, while N30P30K30 + Intermag Titan also showed high productivity. Dry biomass yield was strongly associated with plant height, confirming the role of structural development in biomass formation. Economic assessment indicated the highest long-term profitability for N30P30K30 + Black Jack. These findings indicate that integrated fertilization is an effective strategy for sustainable miscanthus biomass production on marginal soils. 2026-01-01T00:00:00Z https://dspace.mnau.edu.ua/jspui/handle/123456789/26759 Назва: Combined legume-based sowing systems and microbial biopreparations for restoring degraded chernozem fertility in the Southern Steppe of Ukraine Автори: Панфілова, Антоніна Вікторівна; Panfilova, Antonina; Маркова, Наталія Валентинівна; Markova, Nataliya; Корхова, Маргарита Михайлівна; Korhova, Margarita; Артюшенко, Валерій Васильович; Artushenko, Valerii Короткий огляд (реферат): Soil degradation in the Southern Steppe of Ukraine requires effective biological approaches to restoring chernozem fertility. Methods: This study evaluated the combined use of legume crops, mixed sowings and microbial biopreparations during a 3-year field experiment conducted in 2022–2024. Agrochemical, microbiological and statistical methods were used to assess changes in soil properties and crop productivity. Results: The integrated B5 treatment, combining mixed sowings with Azotokhelp, Helprost Universal, Phytocid and Organic-Balance, produced the strongest response. Humus content increased by 31%, readily available nitrogen by 40%, and the total number of soil microorganisms by 3.2 times. Nitrogen-fixing bacteria increased by 6.4 times, while dehydrogenase activity increased by 4.1 times. These improvements were accompanied by higher crop productivity: soybean yield increased by 75%, chickpea by 64% and lucerne green mass yield by 59%. Protein content and other yield-quality indicators also improved. Conclusion: The findings indicate that integrated legume-based biological management can enhance soil fertility, microbial activity and crop productivity. This approach may support regenerative agriculture and the restoration of degraded agroecosystems, although its long-term stability and economic feasibility require further evaluation. 2026-01-01T00:00:00Z
