Purpose. To improve the technology of caring for giant miscanthus plantations and establish the features of its productivity formation with the use of different types of fertilizers, starting from the second year of crop vegetation. Methods. The research was carried out in the years 2020–2021 in the Bila Tserkva Experimental and Breeding Station of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Agrarian Sciences of Ukraine, which is located in the zone of unstable moisture of the Right Bank Forest Steppe of Ukraine. The design of the experiment included application of mineral fertilizers [ammonium nitrate + ammonium sulfate (N24 + S6 kg/ha a.i.), ammonium nitrate (N24 kg/ha a.i.)] in a row zone in spring, foliar application of humates (Vermisol, 8.0 l/ha, Humifield BP-18, 0.4 l/ha) and complex fertilizer with amino acids (Quantum Aminomax, 0.5 l/ha). Mineral fertilizers were applied before the emergence of miscanthus sprouts; foliar application of fertilizers was carried out in the 5-leaf stage and the second time after two weeks. Results. Giant miscanthus plants in second year of vegetation formed from 18 to 37 shoots with an average weight of 76.3 to 111.0 g, with the maximum weight of one plant reaching 4091 g. In the next year of research, the number of stems per plant and their average weight increased by 1.5–2 times, and the maximum weight of one plant was 7016 g. Biomass yield of giant miscanthus in the third year of vegetation was 31.0–74.6 t/ha, the estimated yield of solid biofuel was 19.2–41.6 t/ha and energy 315.5–683.2 GJ/ha. Conclusions. Application of mineral fertilizers (ammonium nitrate + ammonium sulfate, ammonium nitrate) in spring contributed to significant increase in the indicators of raw biomass yield, solid biofuel output, and energy yield per hectare. Foliar application of Humifield BP-18 has a significant positive effect on the productivity of giant miscanthus. The best indicators of crop productivity were obtained in treatments combining spring fertilization with ammonium nitrate and ammonium sulfate (N24 + S6) followed by two-time foliar application of humates (Vermisol, 8.0 l/ha, Humifield BP-18, 0.4 l/ha) and complex fertilizer with amino acids Quantum Aminomax, 0.5 l/ha.

Purpose. Investigate the accumulation of 137Cs and 90Sr radionuclides in the biomass of giant miscanthus depending on the agronomic methods of growing it on radioactively contaminated soils in Polissia. Method. Biomorphological, radiometric, lysometric, statistical, comparative and computational. Results. The article presents the results of research to study the accumulation of radionuclides 137Cs and 90Sr in the biomass of giant miscanthus. It was found that in the variants where the bioenergy crop was grown on soils contaminated with radionuclides, the accumulation of 137Cs in the biomass in the range of 14.7–18.6 Bq/kg and 90Sr — 0.46–0.54 Bq/kg was observed. The use of mineral fertilizers together with liming and inoculation with giant miscanthus with the microbial preparation Polymyxobacterin and treatment with organo-mineral fertilizer BioMAG helped to reduce the accumulation of radionuclides in the biomass of giant miscanthus as following: 90Sr — by 15% and 137Cs by 21%. It was investigated that the use of these agronomic techniques contributed to the formation of dry biomass yield at the level of 9.96 t/ha on average over three years of cultivation, which is 28% higher than the control. Conclusion. It is established that the use of mineral fertilization in combination with liming, inoculation of rhizomes of giant miscanthus with the microbial drug Polymyxobacterin and pre-planting treatment with organo-mineral fertilizer BioMAG contributes to a significant increase in dry biomass yield with reducing 90Sr and 137Cs. The accumulation of these radioactive isotopes in the biomass of giant miscanthus when grown on radionuclide-contaminated soils did not exceed the permissible level for cereal grains, and the use of agronomic techniques helped to reduce the content of 90Sr by 9–15% and 137Cs by 12–21% compared to control. The lowest coefficients of radionuclide conversion into biomass of giant miscanthus were obtained for both 90Sr (0.15) and 137Cs (0.24) for the use of mineral fertilizers together with liming and inoculation of giant mismanthus rizomes with Polymyxobacterin and treatment with BioMAG organo-mineral fertilizer.

The paper highlights the peculiarities of growing miscanthus for energy purposes in the conditions of drained peat bogs at the Panfl Experimental Station of the NSC "Institute of Agriculture of the NAAS". The economic and ecological advantages of growing energy plantations on reclaimed organogenic soils in comparison with rainfed lands in the zone of the LeftBank Forest-Steppe of Ukraine are argued. The study substantiates the technology and the inﬂuence of its individual elements on the productivity of miscanthus giant growing for energy purposes on old-sown hayfelds of carbonate peatlands of the Forest-Steppe. The optimal biometric parameters of the planting material, as well as the planting density, the depth of the rhizomes embedding, the inﬂuence of the planting time on the growth and development indicators of the studied culture were determined. Developed and patented agrotechnical, together with a biological method of combating wireworms, which provides effective protection of miscanthus plants at the beginning of the establishment of energy plantations. An environmentally friendly weed control technology has been applied, which excludes the use of chemicals, the introduction of herbicides, which, in turn, does not allow contaminating soil and river waters with harmful elements. The peculiarities of the nutrient regime of the soil and its biological activity in the experimental plots of Miscanthus giant on the drained carbonate peatlands of the Left Bank Forest-Steppe of Ukraine have been investigated. The effect of potash fertilization, as a key element in plant nutrition on organogenic soils, on the productivity of bioenergetic plantations of Miscanthus is studied. The energy output of bioenergy plantations per unit area has been determined depending on the elements of the cultivation technology. Calculations of economic and energy efciency have been carried out. The developed technology for 3 years of miscanthus cultivation ensures the yield of dry biomass at the level of 23.7–26.1 t/ha or 403–444 GJ/ha of energy. The best economic indicators were obtained on the option with a planting scheme (0.7 X 1.4 m) 10 thousand/ha, where the level of proftability made – 56 %, the cost of dry biomass made 529.6 UAH/t and the conditional net proft – 13157 g/ha. Further directions of scientifc research on the creation of bioenergetic plantations from Miscanthus Giganteus on drained carbonate peatlands of the Left Bank Forest-Steppe of Ukraine have been substantiated. Key words: miscanthus, mass of rhizomes, planting density, fertilizers, productivity, proftability.
