Abstract
The height of millet rods depended more on the year of cultivation, the plants of the second year of vegetation, regardless of the studied factors provided higher linear measurements of plant height from 108.5 to 152.2 cm in comparison to plants of the first year of cultivation from 64.1 to 70.2 cm. higher linear measurements of plant height were obtained at a row spacing of 30 cm, both in plants of the first and second year of vegetation. In plants of the first year of vegetation from 65.2 to 70.2 cm, and in plants of the second year of vegetation from 123.5 to 152.2 cm. Lower linear measurements of plant height were observed for row spacing 45 cm from 64.1 to 69.4 cm in plants of the first year of vegetation and from 108.5 to 138.3 cm in plants of the second year of vegetation. In plants of millet twigs there are some differences in forming a number of stems depending on the year of vegetation, in plants of the first year of vegetation the highest number of stems was 30 cm wide between rows and varied from 405.1 to 443.3 pieces / m2. However, in the plants of the second year of the growing season, the highest number of stems was obtained with a row spacing of 45 cm and varied from 457.5 to 488.1 units / m2. Moreover, the highest number of stems was obtained in plants of millet twigs for sowing in the first decade of May - 429.8 and 442.6 pieces / m2 in the varieties Cave-in-Rock and Foresburg. The highest level of dry biomass yield was obtained for row spacing of 45 cm from 7.0 to 8.2 t / ha, and for row spacing of 30 cm from 6.7 to 7.5 t / ha. Plants of the second year of vegetation provided a higher level of dry biomass yield, which varied from 6.9 to 8.2 t / ha. Dry biomass yields were also affected by sowing dates, the highest mass of dry biomass was obtained during sowing in the first decade of May in Cave-in-Rock varieties - 5.7, and in Foresburg variety - 6.0 t / ha.
