Intensification of agricultural production provides the development and introduction of new, progressive, and cost-effective practices, including plant growth regulators. The effect of various growth regulators on the productivity of fodder beet of the Eckendorf yellow variety type was studied in the conditions of the Central-Non-Chernozem region of the Russian Federation in an experimental field in the Kaluga branch of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy in the period from 2019 to 2021. The studies found that the level of productivity of fodder beet under the action of various growth regulators relative to the control variant significantly increases during pre-sowing seed treatment on 5–10,9% and when using phytoregulators by vegetation on 4,8–11,5%. The most significant increase in productivity and the yield of absolutely dry substances of root crops were noted in an intensive version of the technology using growth regulators Biodux and Zircon. The yield range for three years with these regulators was in the range of 560–561 c/ha, the yield of ACB was 72,5–72,8 c/ha during seed etching, and 559–564 c/ha and the yield of ACB72,5–73,1 c/ha during foliar treatments. In general, the percentage increase in the content of absolutely dry matter of fodder beetroots relative to the control variant with the use of growth regulators was 0,24–0,25%, the increase in the yield of feed units for variants with pre-sowing use of growth regulators was 3–6,6 c/ha or 4,9–10,9%, with foliar application – 2,8–7 c/ha or 4,6–11,5%. Thus, the research work for 2019–2021 proved the effectiveness of modern growth regulators in the Non-Chernozem zone of the Russian Federation.
