The purpose of the study was to determine the possibility of the application of Biochar as an additive substrate for seedlings growing. Three types of the substrate with woody Biochar were investigated. As a control, the peat and perlite (1:1) substrate was used. Some morphological signs (stem height, leaf number, leaf area, root volume, etc.) and physiological indicators of the seedling plants were determinate. The effect of biochar depends on both its quantity and the other components. The using of the substrate mixture with peat:perlite:biochar (1:1:1) provoke a positive effect on the development of the root system. The volume of the root system increased by 36.8% and the weight by 28.4% compared to the control. The physiological status of the plants has improved. The total chlorophyll content and the dry matter content in the plant organs increased.
