The article presents the indicators of economic efficiency of growing miscanthus biomass for the production of solid biofuels. The energy efficiency coefficient is calculated as the ratio of energy input to energy output. The aim of the study was to assess the efficiency of the use of plant growth-promoting and regulating products Vympel-K and Quantum-Gold in the cultivation of miscanthus biomass in the Left-Bank Forest-Steppe of Ukraine. Results. Return on investments starts since the third year of harvesting. The gross income after the fourth vegetation season was 392 900 UAH per hectare. The highest energy efficiency index (4.2−4.4) calculated for the first-year harvest was in the following treatments: single and double dose of NPK, single and double treatment with Vympel-K. Profitability in these treatments was the highest and ranged from 345.3 to 341.4%. The proposed new component of cultivation technology − soaking the rhizomes before planting in the growth-regulating and promoting products Quantum Gold and Vympel-K is economically justified. The return on investments after the sale of the miscanthus biomass for the use of these techniques starts since the third year of cultivation.
