SF 559

SF 559 is a mid-early sunflower hybrid developed for high-efficiency cultivation using the Express® technology. It is characterized by high maturation energy, allowing the vegetation period to be completed earlier and timely transition to sowing winter crops. The vegetation period ranges from 106 to 115 days, and the plant height reaches 160-170 cm. The mass of 1000 seeds is about 72 grams, indicating good seed material quality. The hybrid is recommended for cultivation in areas with different levels of moisture: under conditions of sufficient moisture, the optimal sowing density reaches 55 thousand plants per hectare, and in arid regions — 45-50 thousand per hectare.

One of the key features of SF 559 is its high resistance to sunflower rust races A-G and tolerance to the herbicide Express®, which significantly facilitates the protection of crops from weeds and parasites. In addition, the hybrid demonstrates high resistance to Phoma brown spot and drought conditions, ensuring stable oil content and high yield even under unfavorable climatic conditions. These qualities make SF 559 a reliable choice for farmers seeking to obtain quality and stable sunflower harvest.

The SF 559 hybrid is suitable for cultivation in various climatic zones and ensures effective use of agronomic techniques. Due to its adaptability and resistance to diseases, it contributes to reduced costs for plant protection and increased production economic efficiency. The use of this hybrid allows obtaining high-quality raw material for the oilseed industry, making it in demand on the sunflower seed market.
