The article considers the biological significance of table carrots in human life and the country's economy. It is concluded that the value of table carrots, first of all, is explained by the presence in its composition of a large set of useful substances for the vital functions of the human body. The special value of carrots is that its varieties have an orange color of roots containing carotene (provitamin A), which in humans and animals is converted into vitamin A. Named the most promising hybrids of carrots, lists the basic climatic requirements for growing high yields of this vegetable. The most important conditions of organic carrot cultivation are briefly described. The stages of the technological scheme of carrot cultivation by organic technology are described and the influence of organic cultivation technology on the biometrics of the carrot plant in 2018–2020 is estimated. Analyzing the results of a field experiment on organic cultivation of table carrots, we can say that as a result of organic cultivation and simultaneous application of organo-mineral fertilizer HelpRost vegetables or HelpRost Boron plant height of Abaco F1 hydride was the highest and amounted to 76 cm, which exceeded the height of control plants almost 1.5 times. The variants in which the Abaco F1 and CB 7381 MS F1 hybrids were grown were characterized by the corresponding length. In these variants, the length of the root was the longest and was 16 and 17 cm, respectively, which exceeded the control variant by 4 and 5 cm, respectively. It was found that the bacteria Azotobacter chroococcum and Bacillus subtilis of the biological product of BTU-Center and chelated microelements, improve the biometrics of the plant and root crop (most positively for the root of Abaco F1 hydride where their value can be 5.1 cm. The yield of table carrot hybrids using organic technology, t / ha for 2018–2020 was studied and it is said that the highest yield can be obtained by growing Abaco F1 hybrid, where its value reaches 68 t / ha . During the cultivation of hybrids Bolivar F1 and SV 7381 MS F1 the yield is lower, is only 61.0-62.5 t / ha and exceeded the yield of Olympi F1 hybrid by 9 and 6%, respectively.
