Tiaki — a high-yielding, early-maturing sunflower hybrid developed in accordance with modern agricultural requirements and adapted to various growing conditions. The vegetative period is 100–110 days, enabling a stable harvest in a short time. Plants reach a height of 155–175 cm, and the flower head diameter varies from 17 to 23 cm. Oil content in seeds is 50–52%, making this hybrid attractive for oil production. Yield potential reaches 4.5 t/ha or 54 c/ha, confirming the hybrid’s high productivity. Tiaki hybrid exhibits high resistance to major sunflower diseases, including sunflower downy mildew (race G+), fomosis, fomopsis, rust, false powdery mildew, gray and white mold. Resistance levels to these diseases are rated 8–9 out of 10. Additionally, the hybrid shows high drought tolerance and resistance to lodging and shattering, ensuring crop preservation under adverse weather conditions. Tiaki is also tolerant to sulfonylurea herbicides, simplifying weed control. Sowing density recommendations depend on soil moisture levels: in adequately moist zones, 55–65 thousand plants per hectare are recommended; in moderately moist zones — 50–60 thousand; and in poorly moist zones — 35–52 thousand plants per hectare. Seeds undergo comprehensive treatment with fungicides, pesticides, microfertilizers, and growth stimulators, promoting rapid and uniform plant development. Tiaki hybrid is characterized by adaptability to sowing dates and stable yield, making it an advantageous choice for farmers aiming for efficient and high-quality sunflower production.
