Zhemchuzhina

Zhemchuzhina — this is a medium-maturing hybrid sunflower (Helianthus annuus L.) intended for cultivation in various regions, including the Lower Volga, Central Chernozem, and North Caucasus. The plant is characterized by high height at maturity, absence of branching, and green leaf color with moderate rugosity. The flowers have yellow ligule coloration, and the seeds are distinguished by weakly expressed marginal stripes. The hybrid belongs to the first generation and is suitable for linseed oil production, with oil content in the seeds around 48%. Average yield reaches 24.6 c/ha, with maximum yields up to 43.6 c/ha, indicating high productivity of the variety. The hybrid exhibits high drought resistance and resistance to major sunflower diseases such as downy mildew (races A-H), false powdery mildew, fomopsis, and brown rust. This makes it a reliable choice for cultivation in various climatic zones. Moreover, the variety is compatible with Clearfield technology and convenient for use with the herbicide Euro-Lighting, providing effective weed control and improving crop quality. For improved growth and development of sunflower Zhemchuzhina, it is recommended to use a long-acting liquid organic-mineral complex containing nitrogen, potassium, magnesium, calcium, boron, and other microelements. This complex stimulates plant development in early stages, prevents chlorosis, activates photosynthesis, and enhances immunity, reducing the risk of fungal diseases. It contributes to increased vegetative mass, formation of the flower head, and full maturation of seeds, ultimately increasing yield and product quality.
