Branitskyi Yurii Yuriyovych - Director of the Uladovo-Lyulinetsky Experimental Breeding Station of the Institute of Bioenergetic Cultures and Sugar Beet NAAS (Vinnytia region, Kalynivka, district, Uladivske, Samolevska Str., 15).

Mazur Oleksandr Vasyliovych  – Candidate of Agricultural Sciences, Associate Professor of the Department of Plant Production, Selection and Bioenergetic Cultures of the Vinnytsia National Agrarian University (21008, Vinnytsia, Soniachna Str., 3, e-mail: vd@vsau.vin.ua).

The article presents the quantitative indices of prolapse grazing plants depending on the technological methods of cultivation. The maximum number of leaves of Cave-in-Rock varieties – 2382,1 and Carthage  –  2006,9 pcs./m² was obtained on the variant of research, where the sowing took place at the first  decade of May, which is higher compared to the variant where the sowing was conducted in the third decade of May at 143,4 and 96,6 pcs./m².

The higher weight of a dry sheaf and dry plant was obtained from the variant where the sowing was carried out in the first decade of May – 1,2 and 1,02 kg / m², and 2,55 and 2,51 g for the varieties Cave in-rock and Carthage, respectively.

The highest number of leaves per plant was obtained in the variant where plants were grown with a width of 45 cm between rows in Cave-in-Rock millet varieties – 2304,2 pcs / m² and Cartage – 2003,6 pcs / m². A larger weight of the dry sheaf was obtained in the variant of the experiment, where plants were grown with a width of rows 45 cm between the Cave-in-rock varieties –  1,22 and 0,94 kg / m², which is more than the option with a width of between the rows of 15 cm at 0, 39 and 0,23 kg / m², and compared with the variant, where plants were grown with a row spacing of 30 cm by 0,19 and 0,08 kg / m² more. The weight of the dry sheaf was higher in the experiment where pre-sowing tillage included two pre-sowing cultivations before and post-harvest rolling in the Cave-in-Rock millet varieties – 1,19 and Cartage –             1,02 kg / m².  The highest  weight of  the dry sheaf  was obtained in the experiment,

where manual weeding and inter-row treatments were carried out at intervals of 10-14 days for the Cave-in-rock millet varieties  –  1,19 and Kartag  –  1,02 kg / m², which was higher by 0,02 kg / m² than on the experiment where the soil herbicide of Primemestra TZ Gold ”50% hp was introduced in the first year of millet cultivation. (4 l/ha) and inter-row treatments were carried out at intervals of 10-14 days.

However, the detected difference between the variants of the experiment was not reliable, which confirms the effectiveness of the second variant of the research.
