RHA SU

Early-maturing efficiency for modern farms

As farmers face increasingly unpredictable weather patterns, the demand for ultra-early sunflower hybrids continues to rise. RHA SU, developed by AF «Sady Ukrainy», represents a specialized solution for those looking to optimize their crop rotation cycle through a very short vegetation period of just 74–78 days.

Agronomic resilience and protection

Despite its rapid development cycle, the hybrid maintains a robust defensive profile against common field threats. This is essential for ensuring that yield potential is not compromised by late-season complications. Key resistance markers include:

• High tolerance to Sclerotinia (white rot).
• Strong defense against Peronospora (downy mildew).
• Effective suppression of Phomopsis and various types of rot that can devastate crop quality during wet conditions.

Clearfield technology integration

The RHA SU hybrid is fully compatible with the Clearfield production system. By allowing the use of imidazolinone-based herbicides, this hybrid gives growers a sophisticated tool for post-emergence weed control and management of broomrape. This technological synergy minimizes the need for mechanical weeding and ensures a cleaner field throughout the growing season.

Market positioning

AF «Sady Ukrainy» has positioned RHA SU as a strategic tool for high-intensity farming. Its early maturity allows for timely harvesting, providing growers with the flexibility to clear fields for winter crop sowing well ahead of schedule. By prioritizing development speed without sacrificing health, RHA SU has earned a reputation as a reliable, locally-adapted choice for farmers who need to secure their harvest before late-season risks take hold.
