Purpose. Revealing of adaptive properties of plant varieties of red beet Bordeaux Kharkivskyi and Aktion based on the study of plant growth regulators for marketable production in the Steppe zone of Ukraine. Methods. Field, laboratory ones, variance analysis. Results. The influence of plant growth regulators (Lignogumat, Betastimulin) on earliness and productivity of such red beet varieties as Bordeaux Kharkivskyi and Aktion was established. Conclusions. Plant growth regulators (Betastimulin, Lignogumat) stimulated seed sprouting of red beet Bordeaux Kharkivskyi and Aktion varieties, activated vegetative plant growth increasing marketable yield. Application of Betastimulin (0.2%) for red beet Kharkivskyi Bordeaux and Aktion varieties provides the highest number of marketable beetroots, thus forming marketable yield of 44.7 and 54.9 t/ha respectively with the average beetroot weight of 328–519 g.
