Sunflower B 7313 U

Practical Experience with «V 7313 U»

When discussing hybrids from the «Novagrain Selection Center», experienced agronomists prioritize plasticity. The «V 7313 U» hybrid is exactly where three-line selection proves its worth in the field. Over three seasons of working with this crop, we have identified several key factors essential for sowing and maintenance.

Adaptability and Disease Resistance

With increasingly unpredictable summers, a crop's ability to withstand pathogens is paramount. «V 7313 U» reliably resists phomopsis and various types of rot, including white and charcoal rot. In practice, this means fewer fungicide treatments, significantly lowering the production cost per ton. The convex shape of the seed head allows moisture to shed quickly, minimizing rot risks during a rainy autumn.

Technological Features

• Herbicide Compatibility: The main advantage is compatibility with the «Euro-Lightning» system. For us, this is critical, as it allows controlling major weeds and broomrape in a single pass.
• Vegetation Period: The 90–100 day cycle makes this sunflower an ideal component for crop rotation. We harvest it comfortably before the peak autumn rains, ensuring seed quality is maintained.
• Oil Content: The 45–50% oil content is confirmed not just on paper, but by elevator measurements. The seeds are heavy, full, and well-developed.

Harvesting Efficiency

Standing at 150–160 cm, the plant is not prone to lodging, which simplifies combine operation. The moderate height allows the header to handle less biomass, and the uniformity of the crops makes the threshing process nearly continuous. During drying, the grain does not require extreme temperatures, which saves energy costs for the farm.
