“…According to the analysis of literary sources [Roik et al, 2011;Heletukha et al, 2013;Heletukha et al, 2013;Dumych et al, 2013;Liu et al, 2023] it can be determined that research on the energy potential of perennial herbaceous phytocenosis of Ukraine and measures to increase their energy productivity has been carried out rather limitedly. The relevance of further research on this issue increases due to the increase in the cost of non-renewable primary energy sources and the decrease in the need for grass feed, as the number of livestock decreases [Kurgak, 2010;Woźniak, 2019;Lys et al, 2023].…”

The depletion of traditional energy sources and the increase in the cost of energy resources have a negative impact on the determination of the cost of production of agricultural and industrial products, which leads to a decrease in its competitiveness at the international level. Thus, the main task of the state is to ensure the efficient use of its own fuel and energy reserves and to diversify the sources and routes of supply of energy resources. Ukraine has all the necessary prerequisites for the widespread introduction and application of advanced technologies for growing and processing biomass and energy crops. The development of bioenergy technologies will help solve the problem of providing the country with energy resources, improve the environmental situation in the regions and help increase the employment of the local population. The fundamentals of growing less common energy crops are considered, the works of both domestic and foreign scientists are analysed, including the selection of the optimal place and soil, the establishment of optimal types of promising sparsely distributed energy crops, as raw materials for the energy sector of the state. Particular attention is paid to the need to improve the elements of technology in order to achieve a greater increase in biomass.

“…First of all, these are individual features: species specificity, phase of development, period of ontogenesis, etc. However, it is directly dependent on growth conditions: soil, climatic, and other factors (Grygus et al, 2018b;Kurgak, 2010;Travleev et al, 2004;Jena, 1994;Kuzemko, 2008). Chemical analysis of feeds is considered a necessary condition for assessing their nutritional value, although its results are the first step in such an assessment.…”

The main representatives of meadow Poaceae and Fabaceae of Poltava region are established and their ecomorphic analysis is made 93 species of meadow Poaceae have been found in meadow phytocenoses, which are grouped into 44 genera. Among the found cereals on biomorphs are dominated by perennials (73.0%), on climamorphs among them approximately the same number of cryptophytes and hemicryptophytes, consideration of hygromorphs of the family indicates the predominance of mesophytic plants (56.0%), the bulk of species by tropomorphs belongs to mesotrophic (46.0%), viewing heliomorphs of identified family members indicates their photophobia. 71 species of Fabaceae belonging to 16 genera were found in the meadows. According to biomorphs, most of the identified species are perennials (73.0%). According to ecomorphs, mesophilic, light-loving species, which love soils of medium richness (more than half of all identified species), predominate among the studied species. The consequences of studying the protein in meadow Poaceae and Fabaceae of Poltava region are given. The total protein accumulation in the species studied by us was in the range of 2.5–25.8%. The average values for families are given and specific quantitative indicators of separate genera and species are given. The division of the studied species into three groups according to the content of the indicator is proposed: with low (up to 6.9%), medium (7.0-13.0%) and high (more than 13.0%) number. The studied species were analyzed on a scale of protein content (from 0 to 20 points). According to the given score, the studied cereals are in the group of species with low and medium content, and legumes - medium and high. In the dynamics of protein content during the phases of the growing season you can see a certain trend. Maximum protein is accumulated by representatives at earlier stages of ontogenesis. Analysis of the indicator, depending on their relationship to the biomorph showed some patterns. Thus, annual species, on average, contain an indicator at the level of the second group, and perennial - all three groups. Two-year-olds most often have protein at the level of the third group. This is understandable because they need a lot of nutrients for overwintering and active flowering and fruit formation next year. Moisture conditions also affect protein accumulation. Thus, the studied xerophilous Poaceae according to our research have 9.2 ± 0.4%, mesophilic - 8.2 ± 1.2%. Proven value biomorfy to quantify protein content. It is shown that the concentration parameter affecting growing conditions, including moisture.

“…Due to the imbalance of feed and a significant deficit of protein in the diet of animals, overconsumption of feed reaches 35%, and the cost of production increases by 1.3-1.5 times. The supply of feed unit with digestible protein is often only 80-85 g instead of the scientifically substantiated 105-115 g [1].…”

Goal. To determine peculiarities of formation of phytocenoses, productivity, chemical composition, nutritive value, and energy content of grass forages depending on the options for surface improvement of slope meadows of the mountain forest belt of the Carpathians at different modes of use. Methods. General scientific methods (hypotheses, induction and deduction, analogy, generalization)-to select the work program, and special (field, laboratory, mathematical-statistical, calculation)-to conduct researches and their generalization. Results. Surface improvement of cereals and grasses (with 28% share of low-value in feed terms Nardus stricta) low-productive (1.39 t/ha of dry weight) slope grasslands of mountain forest belt of the Carpathians improves their species composition and chemical composition of feed increases the productivity of the land. Share of sowed cereals or legumes increases to 34-46%. Under the hay regime the highest efficiency as to the output from 1 ha of dry mass was fixed for reseeding mixtures of grasses on the background of N60P30K60 (4.33 t), for the multi-mow regime-reseeding of white clover on the background of P30K60 (3,71 t), that was, respectively, by 14 and 106% more than in the variants without reseeding, and by 146 and 167% more than in the variants without improvement. Among measures of surface improvement influencing forage quality by chemical composition, increasing the content of crude protein, was the introduction of N60P30K60 or 15 t/ha of manure at multi-mow use, and reseeding of white clover-on the background P30K60. Regardless of the measures of surface improvement the highest content of crude protein, the best energy content, and nutritional value of grass fodder were fixed for multi-mow (simulated pasture) mode of use than for hay-mowing. Conclusions. Surface improvement of meadows of the mountain forest belt of the Carpathians with natural grass by operating factors of the improvement of species composition and quality of grass fodder, as well as an increase of their productivity, is the annual entering of N60P30K60 or 15 t/ha of manure, or N60P30K60 + reseeding of grass mixture (Lolium pratense and Phleum pratense) for hay use, or P30K60 + reseeding of white clover for multi-mow use. The best positive effect ensures the application of mineral fertilizers in combination with the reseeding of perennial grasses.
