VK 21 SUR ZU

An Ultra-Early Hybrid for Intensive Crop Rotation

VK 21 SUR ZU represents a specialized solution for farmers who prioritize speed and reliability. Developed by the experts at the V.S. Pustovoit All-Russian Research Institute of Oil Crops, this sunflower hybrid is engineered for regions where the growing season is truncated, either due to climate conditions or double-cropping strategies.

Key Technical Specifications

The standout feature of this hybrid is its extremely short vegetation period of 80–90 days. This allows for harvest to occur before the onset of autumn rains or early frosts, significantly reducing the moisture content of the harvested seeds.

• Oil Content: Stable performance ranging between 45% and 50%.
• Plant Morphology: With a height of 140–150 cm, the plants are manageable for standard harvesting equipment, minimizing grain loss.
• Weed Control: The 'SUR' system implies tolerance to sulfonylurea herbicides, granting growers a clean field environment throughout the season.

Who should choose this hybrid?

VK 21 SUR ZU is an ideal candidate for farming operations that need to clear land quickly for winter crop sowing or those working in high-risk agricultural zones. It is not designed for record-breaking biomass production, but rather for a guaranteed, stable yield within a tight timeframe.

Advantages: High reliability in difficult seasons, ease of harvest, and excellent herbicide tolerance. Trade-offs: Because the vegetation cycle is compressed, the genetic yield potential is naturally lower than that of full-season hybrids. Therefore, it is best suited for growers looking for risk mitigation rather than maximum yield spikes.
