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.

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.

This study aimed to evaluate changes in the quality of selected sweet cherry cultivars after hydrocooling, using a mathematical modeling approach to represent quality characteristics digitally and visually. The investigated samples included the sweet cherry cultivars Valeriy Chkalov, Krupnoplidna, and Melitopolska Chorna, as well as the sour cherry cultivar Vstrecha, which were subjected to preliminary and slow cooling under convective cooling conditions. Unlike conventional sensory evaluation, which relies primarily on subjective organoleptic assessment, the proposed method integrates multiple quality indicators into a comprehensive quantitative model, providing a more objective and informative evaluation of fruit quality. For all investigated cultivars, only minor changes in the quality growth coefficient and the relative quality decline coefficient were observed after hydrocooling, indicating that the selected quality parameters remained stable following low-temperature treatment. Evaluation based on 10 negative and 5 positive quality characteristics showed that the Krupnoplidna cultivar exhibited the most favorable quality profile, with the smallest area of negative factors. In contrast, the Melitopolska Chorna cultivar showed the least favorable quality profile, with the highest number of negative parameters and the lowest relative quality growth coefficient. The proposed modeling approach provides an effective tool for the quantitative assessment and comparative analysis of the quality of fruit and berry products after hydrocooling.

Military operations in southern Ukraine have caused severe degradation of agricultural soil, leading to reduced fertility, disrupted structure, contamination and increased salinity. These changes threaten the sustainability of fruit and vegetable production and regional food security. Existing studies emphasize the need for integrated restoration approaches; however, there remains a lack of experimentally validated, comprehensive methodologies that combine biological, agrotechnical and ameliorative measures. This study aimed to assess soil degradation processes and compare the effectiveness of three restoration strategies – minimal intervention, biological remediation and comprehensive restoration – under real farming conditions in the Kherson, Mykolaiv and Zaporizhzhia regions. Results and conclusions. An initial soil analysis revealed significant fertility decline: humus decreased to 2.1 % (vs. 3.4 % in control), nitrogen to 0.12 %, phosphorus to 58 mg/kg and potassium to 82 mg/kg, alongside increased compaction and reduced water permeability. Among the approaches tested, minimal intervention showed limited improvement (humus went up to 2.3 %; recovery effect ≈ 12 %). Biological remediation produced a moderate gain (humus up to 2.8 %; effect ≈ 55 %), demonstrating the role of organic inputs and microbial activity. The most effective approach was comprehensive restoration, combining biological, chemical and physical measures, which increased humus to 3.2 % and achieved an 84 % recovery effect. This approach also significantly improved nutrient balance, reduced salinity and restored soil structure. The findings confirm that isolated mineral fertilization is insufficient for degraded soil, whereas integrated technologies ensure faster and more stable recovery. The study highlights the importance of site-specific, multi-component restoration strategies as a foundation for post-war agricultural rehabilitation and long-term soil productivity in affected regions.
