BOYARIN is a variety of spring barley (Hordeum vulgare L.) distinguished by its medium-early maturation period and high adaptability to various climatic conditions. The plant is of medium height, with a semi-erect bush and a cylindrical, loose spike of medium density. The mass of 1000 grains varies from 41 to 60 grams, indicating the formation of large and high-quality grain. The vegetation period is 69 to 80 days, allowing the variety to be used in various regions, including the Volga-Vyatsk, North Caucasian, Middle Volga, Lower Volga, Ural, and West Siberian regions. The variety is characterized by resistance to lodging and drought, making it a reliable choice for cultivation in conditions of limited moisture. BOYARIN has good resistance to a range of diseases, including striped smut, helminthosporium, rust, and loose smut, which contributes to maintaining yield and grain quality. Protein content in the grain reaches 12.2%, making it valuable for feed purposes and the food industry. Average yield in various regions ranges from 39.6 to over 75 centners per hectare, confirming the high productivity of the variety with proper agrotechnical approach. Additionally, the BOYARIN variety is used not only for grain production but also for hay and pasture use, and is suitable for creating lawns. Seeds of the variety have good winter hardiness and drought resistance, expanding the possibilities of its application in various agro-climatic zones. For successful cultivation, it is recommended to follow agrotechnical measures, including soil treatment, sowing, crop care, and harvesting, ensuring maximum return from the crops.
