Stacy sunflower is a high-yielding hybrid with early maturity, exhibiting high resistance to various stress factors and a broad spectrum of diseases (A-G+). This variety is distinguished by its drought and heat tolerance, making it an optimal choice for cultivation in southern and southeastern regions. The vegetative period lasts approximately 105-112 days, enabling the hybrid to successfully adapt to various climatic conditions. Plant height reaches 165-175 cm, promoting good development and yield formation.
The oil content of Stacy sunflower is at the level of 51-53%, and its yield potential reaches 55 centners/ha. Seeds are treated with a complex of fungicides and microfertilizers, including nutrients and growth stimulators, ensuring reliable protection against diseases and maximizing the hybrid's potential. The hybrid is resistant to diseases such as downy mildew, gray mold, phomopsis, rust, septoria, phoma, and alternaria, as well as pests including the sunflower weevil and sunflower moth.
The cultivation technology of this hybrid involves the use of herbicide protection systems, particularly Clearfield and Granstar, allowing the application of tribenuron-methyl-based herbicides up to 50 g/ha without harm to the plant. The recommended planting density varies depending on moisture conditions: 55-60 thousand plants per hectare under adequate moisture, and 45-55 thousand plants per hectare under limited moisture. Thanks to its characteristics and comprehensive resistance, Stacy sunflower is a reliable and highly efficient choice for modern farmers.
