Abstract

Maintaining and improving product quality in the cultivation of agricultural crops is one of the most pressing tasks. Due to this, the study of product quality is required in all scientific works. The quality of the product in the stevia crop depends primarily on the chemical composition of the plant, the presence of minerals and vitamins in the plant and their amount. In the experiment, the leaf yield of the stevia crop was 18.6 c / ha in the control variant without the use of mine ral fertilizers. The highest rate of stevia leaf yield was recorded in the variant where 175 kg / ha of phosphorus fertilizers were applied at a high rate of 32.5 c / ha, with an additional yield of 13.9 c / ha due to mineral fertilizers.
