          One of the main tasks of the agricultural complex is to increase the quantity and quality of crop production. The use of optical radiation (UV radiation) in the pre-sowing treatment of agricultural crops seeds to stimulate growth and increase plant resistance to external factors and increase yields is of great interest. Analysis of the literature on the study of UV radiation in the pre-sowing treatment of various plants seeds showed the fundamental and applied research is still needed to determine the spectral distribution and the optimal radiation dose depending on the crop’s genotype which confirms the relevance of research in this direction.
         The aim of this article is to study the effect of UV-C irradiation of different varieties carrot seeds on their growth processes in the laboratory conditions and their development in the field.
         Germination energy and seed germination were determined under laboratory conditions on the 5th day and the 10th day, respectively, at an air temperature of 24+20 С. It was established the UV-C radiation at doses of 120-150 J/m2 has a positive effect on carrot seeds, since the germination increases by more than 27%. The decreasing in growth parameters of several times is observed at doses of UV radiation above 200-250 J/m2. Laboratory studies were confirmed by the results obtained in the field, in which the seeds germination irradiated with a dose of 120 J/m2, was higher by 43% when compared to control samples. The amount of carrots harvested from irradiated seeds exceeded the yield of the control sample by 1,9 times.
         Thus, UV radiation in the pre-sowing treatment of carrot seeds can be successfully used as a stimulator of growth processes to increase of the germination energy and seeds germination, and can also be recommended for a number of crops for which other methods of seed preparation did not yield satisfactory results.
