GSF P 21 is a medium-early simple sunflower hybrid with high plasticity and adaptability to various soil-climatic conditions. The hybrid's vegetation period is 110-113 days, and plant height reaches 160-165 cm. The sunflower head is slightly convex, 20-22 cm in diameter, with a semi-tilted position. Oil content in seeds is at the level of 48-50%, ensuring high economic efficiency of cultivation.
The hybrid exhibits high resistance to herbicides of the imidazolinone group (IMI), enabling effective weed control without damage to the crop. Additionally, GSF P 21 shows high heat and drought resistance, making it a reliable choice for regions with variable climatic conditions. Resistance to lodging and shattering is also at a high level, contributing to yield preservation and facilitating harvest.
GSF P 21 has good resistance to major sunflower diseases, including fusarium, fusariosis, rust, false powdery mildew, gray and white rot, as well as to sunflower moth and sunflower aphid. Recommended seeding rate is 55-60 thousand plants per hectare in forest-steppe zones and 50-55 thousand in steppe zones. Seeds undergo high-quality treatment and protection, ensuring readiness for planting and stable results when grown using various technologies.
