    Adaptive properties of plants and yield of energy crops under different growing conditions: A case study from Ukraine
    (2025) Kaletnik, G.; Kulyk, M. I.; Pryshliak, N.; D'omin, D.; Rozhko, I. I.; Кулик, Максим Іванович; Дьомін, Дмитро Геннадійович; Рожко, Ілона Іванівна
    In Ukraine, balancing agricultural efficiency, food security, and energy development is crucial. Energy crops offer a sustainable raw material due to their adaptability and high biomass yields, supporting biofuel production and value-added products like bioplastics and paper. However, the war has severely degraded agricultural land, necessitating reclamation efforts to restore productivity and enhance bioenergy potential. A five-year field study (2019–2023) in Ukraine’s forest-steppe and steppe zones assessed energy crop yields on marginal lands. Research methods included field studies, gravimetric biomass analysis, data visualization, and statistical analysis (ANOVA, LSD at 5% significance). Findings showed that drooping sorghum and perennial sorghum exhibited the highest drought resistance, while switchgrass and drooping sorghum demonstrated the best frost resistance. Drooping sorghum also had the greatest lodging resistance, whereas switchgrass and perennial sorghum were more prone to lodging, particularly in the forest-steppe, suggesting a correlation with precipitation levels. The vegetation pe riod varied by region, influenced by plant biology and environmental factors. In the Steppe, it lasted 170.6–192.0 days, with drooping sorghum having the longest cycle. In the forest-steppe, it ranged from 170.3 to 181.3 days, with switchgrass exhibiting the longest duration. Biomass yields were higher in the steppe (7.8–11.2 t/ha) than in the forest-steppe (7.4–10.4 t/ha). Over four years, switchgrass and perennial sorghum achieved the highest total biomass yields: 56.0 t/ha and 53.6 t/ha in the steppe, and 51.9 t/ha and 51.7 t/ha in the forest-steppe, respectively. Drooping sorghum produced 46.1 t/ha (steppe) and 39.9 t/ha (forest-steppe), while big bluestem had the lowest yield (39.1 t/ha and 36.9 t/ha). Switchgrass and perennial sorghum proved to be the most productive and adaptable energy crops. Their stable biomass production makes them promising candidates for biofuel manufacturing. Future research will explore strategies to enhance yields, particularly through spring foliar fertilization on marginal lands.

    Financial and economic management of the efficiency of energy crop production in the system of smart technological development of labor resources
    (2026-02-19) Lutkovska, S.; Martyn. O.; Калініченко, Олександр Володимирович; Kalinichenko, O.; Кулик, Максим Іванович; Kulyk, M. I.; Prokopenko, O.; Лесюк, Владислав Станіславович; Lesiuk, V.; Лесюк, Альона Станіславівна; Lesiuk, A.
    The article presents the author's concept of integrated financial and economic management of energy crop production using the example of growing fireweed in the forest-steppe zone of Ukraine. The study is based on comprehensive monitoring of the agro-technological cycle, the dynamics of biomass indicators, economic feasibility and energy efficiency in the context of innovation challenges. For the first time, the feasibility of combining adaptive agricultural technologies with elements of smart analysis of labor and material resource productivity has been substantiated, which allows not only to increase yield, but also to optimize costs at all stages of the production process. The results demonstrate that the most effective is the spring sowing strategy, which provides the highest level of profitability and the greatest energy profit. The proposed network model allows structuring technological operations in the form of a logistical sequence taking into account calendar periods and resource provision, which is key for planning the load on personnel. The author's methodology for assessing energy efficiency shows that the energy efficiency coefficient indicates an average level of technological feasibility of the selected model. Thus, the presented system is a unique multidimensional platform for managing energy agricultural production, which can be integrated into strategies for sustainable development of rural areas through the prism of technological transformation of labor resources.
