The article presents economic assessment of technological methods of cultivation of switchgrass. The most effective technologic activities to ensure maximum growth yield of dry biomass of switchgrass and the highest econonomic efficiency. The highest efficiency was obtained at the variant where there have been two pre-cultivation before and after the rolling ladder. The varieties Сave-in-rock and Сarthage the third and fourth years the farming cost of production from the realization of biomass in this variant amounted to 11,875 and 15,390; 9,595 and 13,870 UAH/ha, and profit from sales of products – 4,157 and 7,381; 1,974 and 5,950 UAH/ha and profitability of Cave-in-rock – 92,2 and Сarthage – 75.1 per cent in the fourth year of vegetation. A high level of profitability obtained on the variant, where conducted, only two pre-cultivation the varieties of millet lozovenko the fourth year of vegetation: Cave-in-rock – of 87.0 and Сarthage was 69.2%. The cultivation of plants during second year of vegetation was not effective, the level of profitability at grades Сarthage from 25,6 to -43,3% and cave-in-rock from -12,6 to -36,7%. The highest indicators of economic efficiency were obtained in the variant with row-spacing width of 45 cm from plant switchgrass third and fourth year of cultivation. The varieties Cave-in-rock and Сarthage the cost from the sale of biomass amounted to 12635 and 15675; 7885 and 13870 UAH/ha, and profit from sales of products – 4844 and 7553; 493 and 5950 UAH/ha profitability of millet varieties depended primarily on year of vegetation, width of row spacing and varietal characteristics.

The highest level of profitability obtained from varieties of millet the fourth year of vegetation with a width between rows 45 cm – 75.1% in the variety Cartage and 93.0% of the varieties cave-in-rock. A lower level of profitability obtained for the variant in terms of 2017, where inter-row spacing was 30 cm from millet varieties cave-in-rock – 73,6% and Cartage – 50.5 per cent.
