Positive Effect Of Mineral Nutrition On The Quantity Of Vitamins And Chemical Content Of Stevia (Stevia Rebaudiana Bertoni)

Abstract

In recent years, all over the world, special attention is paid to plants with sweet taste, but not having a negative effect on human health. In developed countries, 6-7% of stevia side is obtained from stevia leaves, which have a sweet honey taste. Which are widely used in confectionery farms. Stevia extracts are over 300 times sweeter than sugar. Also, in the composition in the leaves of stevia contains vitamin C, B1, B2, PP, which is very important for human health. In the experiment, comparatively high indicators for the content of vitamin "B2" 36.0 mg / 100g were noted when using mineral fertilizers in N50 P175 K50. In agriculture, improving and maintaining the quality of products is one of the main tasks. In this regard, all field trials require the study of product quality. In Stevia, the quality of the food depends to a certain extent on the chemical composition of the plants. That is, the content of mineral substances and vitamins in the plant. It has been established that the use of mineral fertilizers increases the content of phosphorus, iron, calcium and other mineral substances. In the experiment, comparatively low values for the iron content of 4.9 mg / 100 g were observed in the control variant without the use of mineral fertilizers. In the variants of the applied mineral fertilizers, the iron content in stevia was 5.1-6.0 mg / 100 g. The highest iron content in the stevia composition, 6.0 mg / 100 g, was noted in the variant with the use of mineral fertilizers at the rate of N50 P175 K50 kg / ha.
