The article highlights the issues of economic and bioenergy efficiency of growing rapeseed of spring hybrid Jura in the conditions of the Right-Bank Forest-Steppe of Ukraine. It is shown that with the recommended seeding rate of 1 million seeds per hectare, economic efficiency will be high when applying the hole of fertilizers N90P75K120. The use of the N120P75K120 fertilizer hole slightly increased costs compared with the high-income option from 4720 to 4947 UAH / ha, however, the profitability decreased to 71 %. A further increase in the fertilizer hole led to a decrease in profitability and profits, as well as energy efficiency. When applying the fertilizer norm N90P75K120, the energy efficiency ratio for growing rapeseed from the spring Jura hybrid is 2.96.
