The dissertation highlights and substantiates theoretical and experimental research, practical problems regarding the formation of yield and quality of Nigella sativa and Nigella damascena seeds depending on the elements of growing technology. The dependence of seed yield and seed quality on varietal characteristics of Nigella sativa varieties – Ivolga and Diana, Nigella damascena varieties – Charivnytsia and Dimetra, as well as on row width – row sowing – (15х15cm), tape sowing – (15х7,5х15 сm), wide-row sowing (30х30 сm) has been established. Under a wide-row method of sowing, more favourable conditions were created for the growth and development of above-ground and underground organs due to a larger area of nutrition, but the yield indicators were higher precisely with the row- and tape sowing methods, which depended on the density of plants. Among the varieties of Nigella sativa, the Ivolga variety was the most productive. Its productivity over the years was 1,32–1,99 t/hа, which is 14,4–20,6 % more compared to Diana variety. The most effective method of sowing was a tape sowing method, with an average seed yield of Nigella sativa over the years of research of 1,46–1,84 t/hа, which is 0,28–0,42 t/ha more compared to a wide-row method. The yield of Nigella damascena plants ranged from 1,17 tо 1,61 t/hа. The average seed yield of Nigella damascena was 0,01– 0,23 t/hа different from that of Nigella sativa, and the yield of Dimetra variety was 0,05–0,06 t/hа higher than that of Diana variety under row- and tape sowing methods. Among the Nigella damascena varieties, Charivnytsia variety was the most productive, the yield increase of which compared to Dimetra variety was 0,09–0,12 t/hа, regardless of the sowing methods. The best method of sowing seeds was a tape method, under which the yield of Nigella damascena seeds was 1,52 t/hа (Dimetra variety) and 1,61 t/hа (Charivnytsia variety).
