| Abstract | Selection of the optimal rate and method of sowing depending on varietal characteristics, the direction of sowing and soil and climatic conditions of cultivation is important for obtaining high yields of camelina sativa. The main goal of our research was to study the influence of the sowing rate on the width of the row spacing on the seed productivity of camelina sativa in the conditions of the Right Bank Forest-Steppe of Ukraine. The research took place in 2021–2023 at the research areas of the Department of Genetics, Plant Breeding and Biotechnology of the Uman National University of Horticulture. Five seeding rates were investigated in the work – 2.0; 3.0; 4.0; 5.0 and 6.0 million/ha for row widths of 15, 30 and 45 cm. The object of research was the promising sample C-121-2, created on the basis of somaclonal variability by cell selection methods. In the course of the conducted experiments, the dependence of the biometric indicators of camelina plants on the norm and method of sowing was established. In crops with a row spacing of 45 cm, at a seeding rate of 4–6 million units/ha, the highest stem height of plants was noted – 84 cm. The most intense branching of the stem was recorded at a seeding rate of 2.0 million/ha in a wide-row sowing method – 8.3–8, 4 pcs. branches per plant. The largest number of pods on a camelina sativa plant (134.0 pcs.) was formed in crops with a seeding rate of 2.0 million/ha and a row spacing of 30 cm. The maximum number of seeds in a pod was obtained in variants with a seeding rate of 2.0 and 3.0 million/ha for wide-row sowing – 14.0 seeds. The highest mass of 1000 seeds were recorded at the sowing rate of 6.0 million/ha and the width of the row spacing 15 and 30 cm – 1.15 and 1.16 g. So, during the cultivation of camelina sativa, the sowing rate and the width of the row spacing have a significant effect on the branching of plant stems, the intensity of pod laying and the formation of seeds. The most intensive branching of the stem, the largest number of pods and the maximum number of seeds in a pod was obtained with the wide-row method of sowing at the 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 at a sowing rate of 2.0 million/ha. The change in the sowing rate and the width of the rows has an insignificant effect on the height of the stem of the plants was established. The greatest influence on the manifestation of individual seed productivity of camelina sativa was exerted by the combined effect of the studied factors – 50.7 %. The share of influence of seeding rate and row width was, respectively, 20.7 and 28.6 %. | ||
