🌼 Turnip rape
An oilseed. Only every 5th year on the same parcel, because of clubroot and Sclerotinia.
Sowing
VYR: start by choosing the parcel. Check soil structure and pH. The same machines as for cereals will do. Pick a variety for the farm.
Soil and parcel
Get structure and pH right before sowing (VYR). The long root looks after soil porosity.
Fertilising
The rate depends on whether you sow spring or winter turnip rape. It is in the VYR guide and is not collapsed into one number here.
Yield and harvest
A contract crop. The yield becomes oil and protein feed (VYR). Watch the crop: pest control is often needed.
🔄 In the rotation
- Role
- Breaks a cereal run. VYR: spring turnip rape would be a good preceding crop for winter rye in southern Finland, but in a late autumn rye sowing easily slips too late.
- Good preceding crop
- Not after an oilseed until the 5-year gap is met (VYR).
- Good following crop
- A cereal is the usual next crop. Winter turnip rape is harvested earlier than the spring type, so it suits rye better (VYR).
- Gap on the same parcel
- Only every 5th year on the same parcel (VYR, clubroot and Sclerotinia).
