🌾 Oat
A spring cereal that breaks foot-rot diseases of barley and wheat.
Sowing
A spring cereal. VYR rye guide: an early oat variety is harvested before other cereals, so the parcel is free in time for winter rye.
Soil and parcel
Oat breaks foot rot of barley and wheat (aoe.fi teaching material and Luke). It is a break crop, not just another cereal.
Fertilising
Fertilise it as a cereal for the parcel. Oat does not have the same VYR one-page sheet as malting barley here, so no single nitrogen figure is copied.
Yield and harvest
Thresh when ripe. If rye is next, an early variety leaves time for autumn sowing (VYR).
🔄 In the rotation
- Role
- VYR: oat is one of the best preceding crops for malting barley, along with oilseeds. Early oat is also a common preceding crop for rye.
- Good preceding crop
- It can follow a cereal to break the disease cycle. The same crop two years running is still a poor preceding crop for itself (aoe.fi).
- Good following crop
- Barley and spring wheat after oat: foot-rot risk is lower than after barley or wheat.
- Gap on the same parcel
- Do not run five cereal years in a row. Luke (2025) classes that as cereal monoculture.
