Sunflower LK 17 is a high-yielding hybrid for oilseed production, designed for cultivation using modern agronomic technologies, including the Granstar technology. It has a medium-early vegetation period of approximately 108 days and a high oil content in seeds, reaching 50-52%. The hybrid is resistant to broadleaf weeds and drought, ensuring stable yields even under water deficit conditions. The yield potential of LK 17 can reach 51 centners per hectare, making it a profitable choice for high returns.
The hybrid exhibits high adaptability to various growing conditions and demonstrates strong early growth vigor, promoting rapid plant development. Plants reach an average height of about 150 cm, with a flower head diameter of approximately 17 cm and a thousand-seed weight of about 69.5 g. LK 17 is resistant to major diseases, including Phomopsis, root and head gray mold, anthracnose, and dry rot, as well as new strains of false powdery mildew. Additionally, the hybrid is genetically resistant to various strains of downy mildew, enhancing its reliability from an agronomic standpoint.
The recommended seeding rate varies depending on moisture conditions: 45-50 thousand seeds per hectare under water deficit, up to 55 thousand under sufficient moisture. LK 17 is well-suited for cultivation in steppe and forest-steppe zones, revealing its potential under intensive cultivation technologies. Thanks to its short vegetation period and resistance to stress factors, the hybrid can be used for late sowing, allowing the formation of early and stable yields. High resistance to lodging and seed shattering ensures yield preservation until harvest.
