Sunflower Arch

Sunflower Arch is a mid-season, high-yielding hybrid with high genetic yield potential exceeding 4.9 t/ha. Plants are medium-height, reaching 150-160 cm, with a 1000-seed mass of 70-75 g and oil content of 50-51%. The period from emergence to flowering is 58-64 days, and to biological maturity — about 115 days. The hybrid features uniform flowering and maturation, even plant height, and even head inclination, ensuring high harvest efficiency. Plants do not shed seeds or fall over, which helps preserve yield.

Arch exhibits high resistance to major sunflower diseases, including false powdery mildew, downy mildew, froge, as well as gray and white rot. Resistance levels to rust and other pathogens are also high, making the hybrid a reliable choice for cultivation under various conditions. The hybrid demonstrates good drought tolerance and stable yield even under stress conditions, confirmed by high tolerance to diseases and adverse factors.

For optimal cultivation, consider the moisture zone when selecting planting rates: 55-60 thousand plants per hectare in well-watered zones and 40-45 thousand in less watered zones. Seed sowing depth varies from 3 to 6 cm depending on soil type. Use herbicides and microfertilizers to enhance productivity. The hybrid is suitable for cultivation technologies such as Sumo (Granstar), which effectively controls weeds and improves growing conditions.
