Experimental samples of biological products based on endophytic microorganism strains were tested on sugar beet root plants. The studies were carried out at ZAI Agrofirm LLC, Zay District, the Republic of Tatarstan. The most effective preparations applied at the early stages (3–4 leaf phase) were RECB – 31 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 44 B (2.0 l/ha), RECB – 50 B (2.0 l/ha), and RECB – 74 B (2.0 l/ha). Biological preparations applied in the row closing leaf phase have an advantage over chemical preparations when applying RECB – 14 B (1.5 l/ha), RECB – 31 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 74 B (2.0 l/ha). At the late vegetation stages, experimental preparations increased the yield. A significant increase was observed when applying RECB – 95 B (1.5 l/ha).
