Cultivation
Brassica napus var. napus
The seeding rate of rapeseed is based on the target plant stand density, as the crop is sensitive to over-thickening, which reduces lateral shoot development and winter hardiness.
In the reference 49 varieties crop Rapeseed, where this is mentioned in the description.
For winter rapeseed, the target spring density is 50–60 plants per m², which requires sowing 65–80 viable seeds per m² in the autumn. Hybrids require 15–20% fewer seeds compared to open-pollinated varieties due to their ability for active branching. For spring rapeseed, the rate varies from 6 to 12 kg/ha depending on the sowing method.
When selecting the rate, it is critical to consider field germination, which decreases with poor seedbed preparation, and seeding depth, which should be 1–3 cm. Excessive crop density leads to a weak root system, lodging, and disease development, while optimal density ensures the formation of robust lateral shoots, which determine yield.
