The article presents the results of a study of the influence of elements of the cultivation technology, namely the use of two basal dressings and phytohormones on the indicators of phenological processes in Nicotiana tabacum plants in the conditions of the Podillia climate. The specific features of the growth and development of two varieties of the Virginia-27 and Burley Silver River were studied. The amount of the biologically active substance - nicotine in the grown raw materials is determined and the biological features of the accumulation of biologically active substances in the raw materials are established depending on the type and technical methods of cultivation. A comparative analysis of the nicotine content was carried out using mineral fertilizers in the proportions N90P120K90 and P90K90 in comparison with plants on the control. A positive effect on the phenological levels of development and acceleration of leaf ripening for 8 days in comparison with the control was noted. A tendency has been found to reduce the amount of nicotine in plants that received basal mineral dressing, compared with plants in the control. Also, we have identified the positive effect of phytohormones on the phenological parameters of grown plants. However, in the conditions of our climate, questions about the cultivation technologies under study and their influence on the chemical composition of the grown plants require more detailed study. On this basis, such studies are necessary both in practical, economic, and scientific medical and biological aspects.
