| Abstract | Goal. To determine the effectiveness of micronutrient seed coating on the organogenesis of sugar beet seed plants and their productivity. Methods. The research was conducted at Uman National University (Ministry of Education and Science of Ukraine) and at the NAAS Tobacco Research Station from 2023 to 2025. The experimental design included treating the seeds of the CMS component and the multigerm pollinator with the microfertilizer Reakom-S-Beet at rates of 18, 22, 26, and 30 ml per sowing unit. Results. The most effective method of enriching plants with micronutrients is pre-sowing seed treatment using metal chelates. Pre-sowing coating of seeds with the microfertilizer Reakom-S-Beet increased the germination intensity of coated seeds under both laboratory and field conditions. Increasing application rate of the microfertilizer from 18 to 26 ml per sowing unit ensured a significant increase in the germination energy of the CMS component and the multigerm pollinator by 13%, and in laboratory germination by 13% and 11%, respectively. nder field conditions, depending on the application rate of the preparation, by fifth day of observations the number of emerged seedlings exceeded control by 3.1–3.5 plants per 2 linear meters of row for the CMS component and by 2.0–3.3 plants per 2 m of row for the multigerm pollinator. The intensity of seedling emergence, together with the high quality of seeds coated with the microfertilizer and soil-climatic conditions, influenced field germination. Even at the lowest application rate of the microfertilizer (18 ml per sowing unit), field germination increased by 8.9% for the CMS component and by 9.8% for the multigerm pollinator. This ensured the formation of an optimal plant density, on which the yield of seed plants depends. Highest yield of both components was obtained when the seeds were treated with the microfertilizer at rates of 26 and 30 ml per sowing unit; however, no statistically significant differences in yield were found between these application rates. Pre-sowing treatment of sugar beet seeds with the Reakom-S-Beet microfertilizer significantly increased the number of root crops suitable for planting compared with the control in both the CMS component and the multigerm pollinator. Conclusions. Pre-sowing treatment of sugar beet seeds with micronutrients significantly increased germination intensity under both laboratory and field conditions and, consequently, improved field germination. The optimal rate of the microfertilizer for seed treatment was 26 ml per sowing unit, which increased the plant density of the CMS component by 34.4% and that of the multigerm pollinator by 25.3% compared with the control. The yield of planting material weighing 150–600 g also increased significantly | ||
