PS 138

Consistent performance in the field

When selecting a sunflower hybrid, reliability is the primary factor for any grower. PS 138 from «Ooo Aktiv Agro» is a simple hybrid with a 120–130 day growing season, designed for those who prioritize predictable results over experimental risks. Having worked with this material, it is clear that it handles environmental challenges with remarkable consistency.

Disease resistance as a priority

The biggest challenge in sunflower cultivation is maintaining crop health. PS 138 provides a robust defense system right from the start. Its high resistance to downy mildew and white rot makes it a standout choice for fields with a high disease background. By minimizing the risk of verticillium wilt, phomopsis, and various rots, this hybrid significantly reduces the pressure to perform frequent fungicide treatments, which directly impacts the farm's bottom line.

• Natural defense: The hybrid’s innate immunity to white rot and downy mildew serves as a reliable shield, saving on input costs.
• Optimal timing: The 120–130 day cycle is perfect for stable maturation, allowing for a timely and efficient harvest schedule.
• Breeding pedigree: Developed by the Ooo Aktiv Agro team (Grigoryan V.V. and Sharygina M.L.), ensuring the genetics are well-adapted to regional conditions.

Operational insights

From an operator’s perspective, the true value of PS 138 lies in its field uniformity. During the harvest, this consistency allows the combine settings to remain stable, reducing mechanical stress and grain loss. It responds exceptionally well to proper crop management and accurate seeding density. It is not a «plant and forget» crop, but rather a professional tool that rewards agronomists who maintain proper field spacing and nutrition. When managed correctly, it produces an even, clean harvest that simplifies post-harvest logistics.

If you are looking for a sunflower hybrid that combines strong pathological resistance with predictable growth characteristics, PS 138 is a robust, value-driven choice for your rotation.
