Rubus fruticosus L. (blackberry) is a perennial, bushy berry plant. It belongs to the Rosaceae family and is widely distributed in Europe, the Americas, the Caucasus, and Central Asia.
The fruits are a rich source of vitamins (C, E, K), minerals, organic acids, and antioxidants. In medicine, blackberries are recommended for liver, stomach, respiratory, and cardiovascular diseases.
In the food industry, they are used frozen, in compotes, jams, juices, and widely in confectionery. Ecological and ornamental importance: the evergreen leaves enrich the air with oxygen, and the root system helps prevent soil erosion. High yield potential: 8–12 tons of berries per hectare. With 2–3 applications, high results can be achieved in a short period. The plant responds well to growth hormones and biostimulants. It grows well in moderate and subtropical regions, especially on fertile, moisture-retaining, irrigated soils.
