| Abstract | Spatial and quantitative placement of plants in the crop, determined by the width of the row spacing and the rate of sowing, are important elements of varietal agricultural technology. With optimal stemness, plants rationally use food, water, and light, favorable conditions for their growth and development are created, and crop productivity increases. The main goal of our research was to study the influence of the sowing rate on the width of the rows on the seed yield of сamelina in the conditions of the Right Bank Forest-Steppe of Ukraine. The research in 2021–2023 at the experimental sites of the Department of Genetics, Breeding and Biotechnology of the Uman National University of Horticulture was conducted. Five seeding rates – 2,0; 3,0; 4,0; 5,0 and 6,0 million/ha with row widths of 15, 30 and 45 cm were investigated in research. The object of the study was the promising sample C-121-2, created on the basis of somaclonal variability by cell breeding methods. In the course of the conducted experiments, the dependence of plant biometric indicators and сamelina seeding productivity on the sowing rate and row spacing was established. The highest field germination of seeds in row sowing was at sowing rates of 2,0 and 3,0 million/ha – 89,7 and 89,2 %, respectively. In wide-row crops, the rate of sowing did not significantly affect this indicator – seed germination was 85 % on average. On crops with a row spacing of 15 cm, on average, plant survival was 67.0 %, and for row spacings of 30 and 45 cm, it was 62.1 and 60.3 %, respectively. The highest biological resistance was noted for sowing rates of 2.0 million /ha – 73.0 %. The largest number of pods per plant (134.0 pcs.) and the maximum number of seeds in a pod (14.0 pcs.) was obtained by the wide-row method of sowing with a rate of 2.0 million/ha. The highest individual seed productivity of plants (2.13 g) was recorded on crops with a row spacing of 30 cm and a seeding rate of 2.0 million/ha. The highest yield (3.06 t/ha) of the crop was recorded in two sowing options: with a row width of 15 cm at a sowing rate of 5.0 million/ha and a row width of 30 cm at a sowing rate of 3.0 million/ha. | ||
