Miscanthus (Miscanthus x giganteus) forms the largest number of stems in the first year of the life cycle. It was found that the height of the main shoot increased with the number of sprayings. Active growth and development of miscanthus plants begins from the tillering phase, which occurs after the appearance of the first true leaves (from May to September) immediately. It was found that the number of shoots increased (from 8 to 12 units per bush) after each foliar sprayings with plant growth stimulants. The largest leave-stem biomass in the first year of vegetation was obtained in the trial of double foliar treatment soaking in a Quantum gold solution. It was found that the yield of the miscanthus rhizome was slightly higher in 2016-2017 than in 2018-2019. Excessive rainfall of 150 mm in May in 2016 gave a significant impetus to the formation of the underground part of the miscanthus. The highest yield of miscanthus 4.6 t ha-1 and energy yield-80 GJ ha-1 was obtained in the trial when soaking in a solution of Quantum gold with two-time treatment of plants during the growing season.
