The results of researches of influence of biological preparations on biometric parameters of plants and productivity of table beet are resulted. The influence of biological preparations on the phases of growth and development of table beet plants, its yield and biometric parameters of products is established. Treatment of plants with the biological complex Organic Balance + Azotophyte + Liposomes accelerated the phenological phases of growth and development of table beet plants. As a result of measuring the height of plants, an increase in control over the treatment of plants with biological products was detected, in particular in the variety Red Ball Organic Balance + Azotophyte + Liposam provided an increase of 1.0 cm relative to control. The increase in plant height in the Pablo F1 hybrid was 2.2 cm with the use of Organic Balance + Azotophyte + Liposam. The largest number of leaves was observed for the treatment of plants Organic Balance + Nitrogen + Liposomes: in the variety Red Ball growth relative to the variant without treatment was 2.3 pcs / plant, in the hybrid Pablo F1 - 2.8 pcs / plant. Treatment of plants Organic Balance + Azotophyte + Liposam contributed to an increase in leaf area by 0.09 dm2 / plant in the variety Red Ball, 0.22 dm2 / plant in the hybrid  Pablo F1. The use of Humifrend + Azotofit + Liposam also contributed to the increase of this indicator with an increase relative to the controls of 0.06 and 0.15 dm2 / plant, respectively. The influence of biological preparations on the biometric parameters of plants was established in the phase of intensive root growth. The largest biometric parameters in the phase of intensive root growth were recorded during the treatment of plants Organic Balance + Azotophyte + Liposam. In particular, the height of plants treated with Organic Balance + Azotophyte + Liposam increased by 2.2 and 3.1 cm compared to the untreated options. A slightly smaller increase in this indicator was recorded for treatments of plants Humifrend + Azotofit + Liposam - 0.8 and 1.0 cm, respectively. 

The number of leaves also increased during the treatment of plants with biological products. In the Pablo F1 hybrid, this figure was higher than the Red Ball variety - 16.0 - 18.7 units / plant. The use of Organic Balance + Azotophyte + Liposam provided an increase in the number of leaves by 2.8 pcs / plant relative to control, for the treatment of plants Humifrend + Azotophyte + Liposam increase was 1.8 pcs / plant. The positive effect of the use of biologicals was observed taking into account the area of leaves. With the use of Organic Balance + Azotophyte + Liposam, this figure in the studied varieties and hybrids increased by 0.8-1.3 thousand m2 / ha, respectively, compared with the control. Slightly less growth of this indicator was observed for the treatment of plants Humifrend + Azotofit + Liposam 0.3-0.7 thousand m2 / ha, respectively. The highest indicators of biometric parameters of plants were observed in the hybrid Pablo F1 for plant treatment Organic Balance + Azotophyte + Liposam, where the increase in plant height was 0.7-1.2 cm, the number of leaves - 1.8-2.1 pcs / plant, leaf area - 0.8-1.1 thousand m2 / ha, respectively. The highest yields were recorded with the application of Organic Balance + Nitrogen + Liposomes: in the Red Ball variety the increase was 7.1 t / ha, in the Pablo F1 hybrid - 10.3 t / ha relative to control. A positive effect was also obtained with the application of Humifrend + Azotofit + Liposam, where the increase was 4.9 and 8.4 t / ha, respectively. Treatment of plants with a complex of biological preparations Organic Balance + Azotophyte + Liposam provided an increase in root mass in the variety Red Ball - 45 g, in the hybrid Pablo F1 - 30 g, respectively. During the treatment of plants Humifrend + Azotofit + Liposam the increase was 30 g - variety Red Ball and 25 g - hybrid Pablo F1. Indicators, the diameter of the root crop was in the range of 8.4 and 9.0 cm. 5 cm. The increase in root diameter with the use of Humifrend + Azotofit + Liposam was slightly smaller and amounted to 0.1-0.3 cm. plants Humifrend + Azotofit + Liposam contributed to an increase in this indicator relative to control by 0.3-0.2 cm
