Valin sunflower is a high-oil hybrid with a vegetation period of 96-100 days, characterized by high resistance to stressful conditions and drought. The plant reaches a height of 150-160 cm and has a convex flower head with a downward orientation. The hybrid features high oil content in seeds — from 46 to 52% — as well as resistance to the aphid. To increase yield, it is recommended to apply microelements such as potassium and sodium humates, as well as mono-hydroxyboron acid during the six-leaf stage. Additionally, there is a decorative sunflower known as Valentine, distinguished by bright lemon-yellow flower heads with a dark center and a height of about 130-140 cm. This annual plant has abundant lateral branching and blooms from June to September. It is ideal for decorating gardens, hedges, lawns, and for making bouquets due to its prolonged and abundant flowering. Valentine sunflower prefers light, warm, and fertile soils, tolerates drought well, and requires minimal care. Sowing of the oil hybrid Valin is recommended in April–May, with spacing between plants of 20–40 cm depending on the variety. For the decorative sunflower Valentine, sowing can be done either directly in the open ground or as seedlings in early April, followed by transplanting, with seeds lightly covered with soil to a depth of 2–5 cm. Both types of sunflower are light-loving crops that thrive best on loose, fertile soils, ensuring high yield and decorative appeal.
