KALIX

Combating Powdery Mildew for Stable Yields

The choice of the «Calix» sunflower hybrid, developed by the French breeder Av Du Capitaine N Tchorere 80270 Airaines France, is a targeted solution for farms operating in environments with high disease pressure. The primary advantage of this material is its robust genetic resistance to powdery mildew. In regions where moderate humidity promotes fungal proliferation, Calix significantly reduces the need for intensive fungicide applications, safeguarding the crop's yield potential from early development stages.

Agronomic Traits and Field Performance

The seed stock is characterized by high uniformity, ensuring optimal machine calibration for precision sowing. Key characteristics include:

• Seed Profile: Available in black and grey-striped varieties with a medium size, which allows for consistent seed spacing and reliable field emergence.
• Head Architecture: The head features a slightly convex shape on the seed side, which facilitates better water runoff during the maturation phase, minimizing the risk of rot during rainy autumns. The large head size ensures substantial seed fill and high bushel weight even under variable climatic conditions.

On-Farm Application and Rotation Strategy

Growers utilize Calix in intensive cropping systems where sunflowers are frequently integrated into the rotation. Developed by originator Annabelle RABLAT, the hybrid is well-adapted to varied soil types, showing consistent performance across different agro-climatic zones. Practical experience shows that Calix is highly responsive to micronutrient supplementation, particularly during the head-filling stage. By utilizing this French-bred material, agronomists can maintain better phytosanitary control over their fields while securing a more predictable economic outcome for the production season.
