Sunflower Subella CL is a mid-early hybrid adapted to various soil-climate conditions and cultivation technologies. It is characterized by high yield and oil content, with oil content in seeds at 49–51%. The vegetative period ranges from 104 to 115 days, ensuring early flowering and maturation. Plants reach a height of 150–165 cm, with flower heads approximately 20 cm in diameter and a semi-erect posture at 45°. The 1000-seed mass varies from 58 to 61 grams, and the planting density at harvest is 55–60 thousand plants per hectare. The hybrid’s yield potential reaches 4.2–4.3 tons per hectare, corresponding to over 40 centners per hectare.
The Subella CL hybrid exhibits high resistance to adverse factors, including heat, drought, lodging, and stem breakage. It also possesses very high resistance to major sunflower diseases, such as powdery mildew, sclerotinia, phomopsis, and gray mold, as well as high resistance to downy mildew. Resistance to fusarium wilt is rated as basic. Thanks to these qualities, the hybrid ensures stable and intensive plant development, contributing to high productivity and quality of the harvest.
The cultivation technology for Subella CL includes the application of modern agronomic practices and plant protection measures. Soil cultivation is recommended to a depth of 15–20 cm, with a seed sowing rate of 60–65 thousand per hectare. Fertilizers such as ammonium sulfate and complex mineral fertilizers with microelements are used to increase yield. In top-dressing, products like Accelerator Micro, Sulphomag, and Carbamide are applied. Soil and foliar herbicides, fungicides, and gramminicides, such as Norwel at a rate of 2.5 l/ha, are used to protect crops from weeds and diseases. All these measures contribute to achieving high yield potential and high-quality oil product.
