On the basis of conducted researches on the study of separate elements of technology in the complex, it was established that Diona varieties with the use of broad-sowing (45 cm) sowing and sowing rates of 600 thousand pp./ha by the time of May 10 formed yields at 2.50 t/ha, but the grade of the Alians provided the best yield for rows of 15 cm for sowing terms of 600 thousand pounds per hectare and the sowing date on May 1 - 2.47 tons per hectare. But for the Avrora variety, for rows of 15 cm and norms of 600 thousand tons/ha and on the 1st of May, they received 2.62 tons/ha of seed, and for sowing 800 thousand tons/ha and the sowing date on May 10 - 2.67 t/ha of seeds.
Consequently, in the Diona sort was obtained for rows of 45 cm, the norm of sowing 600 thousand pieces/seeds and the sowing date on May 10 profit at the level of 23.5 thousand UAH, under similar conditions, the Alians provided profit 25.5 thousand UAH. At the same time, the energy efficiency factor for the Diona variety was 3.03 in these conditions, and for the Alians variety 3.21 in the same variants.
Studies have shown that the Avrora soybean variety for rows of 45 cm and the norm of sowing 600 thousand pieces/seed and the sowing date on May 1 ensured the formation of 27.5 thousand UAH. Net profit, and for sowing 800 thousand units/seed and sowing time on May 10 - 28.0 thousand UAH. At the same time, he had the maximum values of the coefficient of energy efficiency at the level of 3.39 and under condition of sowing 800 thousand pieces/ha for sowing May 10 - 3.43.
According to the results of the research, the quality indicators of the seeds were determined, and the content of the raw protein in the Diona variety was 45 cm in rows, the norm of 600 thousand pounds per hectare and sowing on May 1 - 40.2 %, the same variants of the experiment ensured formation in the seed Alians varieties and Avrora 39.4 and 39.2 % crude protein. The maximum accumulation of raw fats in the Diona sort was 15 cm in row spacing, sowing with the norm of 800 thousand pounds per hectare and the term of April 20 - 20.4 per cent, and width of 45 cm, seeding standards of 600 thousand pcs./ha and the sowing date on April 20 - 20.5 %.
The results of the clustering of the studied varieties indicate that the set of economic and valuable features is as similar as possible to Arissa, Kassidi, Mentor, Luna, NS Maksymus or Podiaka and Kuban, which means that simultaneously sowing these soy varieties cannot help to avoid risks. From the effects of adverse growing conditions. In addition, it has been established that varieties of intensive type can be attributed to yields such as: Kuban, Vidra, Biser.
