Biologization and modernization of the fertilization system with the introduction of N60P60K60 + 4 t/ha of straw for plowing + N10 in pre-sowing cultivation ensured the maximum productivity of sugar beets: root crop yield – 51.2 t/ha, sugar collection – 10.4 t/ha. The specified biologized fertilizer system provided a yield of bioethanol of 5.3 t/ha, and energy of 137 GJ. Cultivation of sugar beets in short-term crop rotations is effective against the background of straw + N10 in the links: Perennial grasses – Wheat – Sugar beets – Barley with subsowing and Vyko – oats with/c – Wheat – Sugar beets – Millet, which ensure the production of bioethanol 3,4- 4.2 t/ha with an energy output of 85-102 GJ, and 7.2-8.5 t/ha of sugar collection. Cultivation of sugar beets in a chain with Vyko - oats (siderate) - wheat - sugar beets - buckwheat on a background of straw + N10, we get 3.69 t/ha of bioethanol with an energy output of 93 GJ and 7.9 t/ha of sugar. Based on the influence of biological depth factors and the method of tillage on the yield of green mass of sugar sorghum, it was established that when the depth of cultivation was increased from 12-14 cm to 20-22 cm, the increase of green mass was 4.85 t/ha, and the increase of the depth of cultivation from 20 -22 cm to 30-32 cm, this difference was 4.06 t/ha. At the same time, the yield of bioethanol in the amount of 3.58 t/ha, the energy content of which is equal to 111.42 GJ, was obtained during tillage of the soil to a depth of 30-32 cm.
