Purpose. To establish the theoretical and practical ground for the application of UAVs in the production of sugar beet seeds in the Right Bank Forest Steppe of Ukraine. Methods. A field experiment was conducted on the Shevchenkivske Experimental Farm of the Institute of Bioenergy Crops and Sugar Beet NAAS (Denykhivka, Bila Tserkva district, Kyiv region) in 2021–2022. Results. The high efficiency of additional pollination of the seed plants of the sugar beet hybrid ‘Shevchenkivskyi’ with the use of DJI Agras T20 drone was proved. During the movement of the drone along a given trajectory over the seed plants of sugar beets, the vertical air currents created by the propellers shake off the pollen of flower-bearing shoots, capture it and transfer it from one plant to another. Thus, along with open (natural) pollination, additional pollination of the seed plants is occured. Additional pollination was performed in the period of mass flowering of seeds in the morning hours (from 9 to 11) − a time when a large amount of pollen is released. The high performance of the DJI Agras T20 drone allows for performing additional pollination many times, which significantly increases its efficiency. On average, over two years, double additional pollination (performed at the beginning of flowering and in the stage of mass flowering of the seed plants) ensured a 0.40 t/ha seed yield increase and a 9% seed germination increase compared to the conventional seed production practice. Conclusions. The effectiveness of setting sugar beet seeds and, consequently, seed yield largely depends on the pollen-forming ability of the seed plants and the fullness of the pollination. Therefore, in the cultivation of hybrid seeds, it is necessary to carry out additional pollination, which increases the number of pollen grains in the pollen cloud above the field as follows: 2.12 times in the 1st row (distance 1.4 m), 1.97 times in the 4th row (3.5 m), and 1.64 times in the 8th row, compared to the control. It was found that from a biological perspective, the most favourable period for single additional pollination is the period when 40–50% of the seed plants are open, compared to 20–30% and 60–70%. At the same time, the highest increase in seed yield and quality was ensured with three additional pollinations: the first when 20–30% of flowers are opened, the second when 40–50% and the third when 60–70%. Therefore, the use of the DJI Agras T20 drone for additional pollination of the seed plants of sugar beet hybrid 'Shevchenkivskyi' appeared an effective agrotechnical practice for increasing seed yield and quality.
