The article reflects the results of the influence of plant biostimulants on the yield and quality of beet roots depending on the timing and methods of their application in the Western Forest-Steppe of Ukraine. According to the research results, pre-sowing treatment of red beet seeds of Akela and Bicores varieties with the growth stimulants Regoplant, Endophyte L1 and Vympel K intensifies seed germination and stimulates plant growth and development, which further increases crop yields. The largest increase in beet roots yield was observed during the treatment of red beet seeds of both varieties with Regoplant at a rate of 250 ml/t – 21.4 t/ha and 18.4 t/ha, respectively. The highest content of dry matter and sugars was observed in the variant with pre-sowing treatment of red beet seeds of Akela variety with the plant growth biostimulant Regoplant – 16.1% of dry matter and 8.9% of sugars. Slightly lower values of the analyzed parameters were observed when treating seeds with the growth stimulants Endophyte L1 and Vympel K, namely 15.9% and 8.8%; 5.8% and 8.8%, respectively. In the variety Bicores there was a similar tendency to increase the quality indicators, but their values are slightly lower.
