Carrot seeds contain essential oils that are inhibitors of their germination. Therefore, pre-sowing treatment of the seeds with solutions of complex water-soluble fertilizers with chelated trace elements is very important. The effect of complex water-soluble fertilizers with chelated trace elements on the sowing qualities of carrot seeds and their productivity was studied in the conditions of the collection site of the Penza State Agrarian University. It was found that the germination energy increases in almost all variants of the experiment. The greatest effect is observed with the combined use of Micromak and Aquamix in doses of 1 ml and 1 g per kg of seeds, respectively. The germination energy was 65%, which is 8% higher than that in the control. Thus, the use of complex macro- and micro fertilizers "Micromak" and "Aquamix" contributes to a faster consumption of spare nutrients and a faster appearance of seedlings and even sprouts, a more intensive transition of seedlings from heterotrophic nutrition to autotrophic. In other words, pre-sowing treatment of seeds with these types of fertilizers improves all indicators characterizing the first stages of ontogenesis of carrot plants. Improvement of the nutritional regime, acceleration of plant growth and development under the effect of seed treatment with complex macro- and micro-fertilizers significantly affected the increase in productivity of garden carrots, which ranged from 46.4 to 52.3 tons per 1 ha, with 39.5 tons per 1 ha in the control. The highest yield was obtained by joint treatment of carrot seeds before sowing with Micromak at a dose of 1 ml and Aquamix at a dose of 1 g per 1 kg of seeds and amounted to 52.3 tons per 1 ha, which is higher than the control by 12.8 t/ha or 32.4% (LSD0.5 t/ha = 4.89). In the same variant, the largest number of commercial root crops was 40.1 tons per 1 ha, which is 14.3 tons per 1 ha more than that in the control (LSD 0.5 t/ha = 6.03).
