Palamarchuk Inna Ivanivna – Candidate of Agricultural Sciences, Senior Lecturer of the department of landscape gardeniing, horticulture and viticulture of the Vinnytsia National Agrarian University (21008, Vinnytsia, Solnyschaya St. 3,e-mail: pal_inna@vsau.vin.ua).

Based on the results of the conducted studies on the study of yield and biometric indicators of beetroot production, it was established that the passage of phenological phases, biometric indicators, the yield is affected by varietal characteristics. The period from sowing to single shoots was shorter for Bordo Kharkovskyi and Bagryanyi – 14 days, for control – 15 days. Mass shoots-intensive formation of root crops was shorter in the Bordo Kharkovskyi breed – 56 days, which is 2 days shorter from the control. The longest period was at the Gopak brand – 59 days. The interphase period "mass stairs – the end of vegetation" was the shortest in the Bordo Kharkovskyi – 119 days, whereas in the varieties Chervona Kulya (control) and Hopak – 125 days.

Bordo Kharkovskyi plants had a high altitude – 36,6 cm, and on the control – 34,6 cm, which is 2 cm less. This variety was characterized by the largest number of leaves, so in the phase of intensive root crop formation this indicator represented 15,1 pieces/plant, which is more than 1,8 controls per plant. The largest weight of root crops in the intensive formation phase was formed by the plants of the Hopak variety – 98 g, while on the control it was folded – 85 g.

The choice of a variety significantly influences the level of productivity of beet table medium. On average, over the years of research, the Hopak grade was 84.6 t/ha, which is 8.3 t/ha higher than the control. The lowest yield, on average for the years of research, was noted in the Bagryanyi variety – 56,9 t/ha, which is less than the control by 19,4 t/ha. Important in assessing the production of beetroot are the biometric parameters of the yield. The largest diameter was characterized by the root crops of the Hopak variety – 9.5 cm, which is 0,3 cm more than the control. The greatest weight of the root crop was formed by the plants of the Hopak variety – 315 g, while the control was 285 g, which is 30 g less. The least weight of the root crop was formed by the plants of the Bagryanyi variety – 215 g, which is 70 g less control.
