Rapeseed KWS PETKOS CL

Agronomic Guidelines for KWS PETKOS CL Cultivation

Developed by KWS MOMONT RECHERCHE S.A.R.L. in France, this intensive hybrid is specifically engineered for the Clearfield production system. Its performance is highly dependent on precise agronomic management and adherence to intensive farming protocols.

Sowing and Field Placement

The optimal sowing window for KWS PETKOS CL is between August 10th and 25th. Early establishment is crucial to ensure the plant develops a robust rosette before winter dormancy. The target plant density at harvest should be 45–50 plants per square meter. Ensure consistent seed depth of 2–3 cm in a well-prepared, fine-textured seedbed to promote uniform emergence.

Soil Requirements and Nutrition

This hybrid thrives in fertile, loamy soils with a neutral pH. Because it is a Clearfield hybrid, crop rotation planning must account for the residual activity of imidazolinone herbicides. A split-application approach for nitrogen is recommended: the first dose applied on frozen soil (40–60 kg N/ha), and the second during the stem elongation phase (60–80 kg N/ha). Boron application is essential for root development and reproductive organ formation.

Growth Stage Management

• Autumn: Weed control and monitoring for flea beetles at the 2–4 leaf stage. Growth regulators may be necessary to prevent premature stem elongation.
• Spring: Early monitoring for weevils and pollen beetles is critical as soon as temperatures rise.
• Flowering: Fungicide application during full bloom is recommended to prevent Sclerotinia and Alternaria infections, ensuring maximum yield potential.
