Barley is a grass family plant, one of the oldest cultivated plants in human history. It is rich in B-group vitamins, PP, E, H, and also contains important micro- and macroelements such as phosphorus, potassium, calcium, iron, iodine, zinc, and others. Due to its high fiber content and complete protein, barley is widely used for food purposes, animal feed, beer production, and cereal manufacturing. The winter barley variety "Snow Queen" deserves special attention for its high frost resistance and resistance to diseases such as powdery mildew, rust, and fusarium. This variety has stable yields of 7–8 tons per hectare under favorable conditions, large grains with high starch and protein content. Plants reach a height of 85–95 cm, and the 1000-grain weight is 40–45 grams. The variety is medium-maturing with medium resistance to lodging, recommended for cultivation in the Polesie, Forest Steppe, and Steppe regions with adaptation. To achieve maximum yield, it is recommended to use starter phosphorus-potassium fertilizers to stimulate root development and apply nitrogenous top-dressings during the tillering stage. Also, fungicides should be applied to protect plants from fungal diseases. Due to its qualities and adaptability, the barley "Snow Queen" is a valuable choice for agricultural production in cold-winter regions.
