Study of nightshade Sunberry in the open ground of the Central Black Earth region
One of the reasons for the insufficient production of natural anthocyanin dyes is a limited assortment mid lack of raw materials for their production. The traditional raw materials for the production of natural food anthocyanin dyes are berries with an intense purple color. Due to the expansion of the assortment and the increase in the volume of organic food production, the demand for natural food anthocyanin dyes has increased significantly. The purpose of the research is to study the Sunberry nightshade in the open ground of the CR on the yield and suitability of fruits for the production of food anthocyanin dyes. Data are presented on the yield of Sunberry nightshade in the open ground of the Central Chernozem Region when grown from potted and without potted seedlings. It is shown that cultivation according to schemes 70x25; 70x30 and 70x35 cm provides a yield of 2.65 to 4.21 kg/m<sup>2</sup> of fruits with a high content of anthocyanins and other biologically active substances.
