Role of Nutrients by Oat Growth Stage
Oat nutrient requirements vary depending on the crop growth stage. Find out which nutrients are most important at different growth stages.
Establishment
- Nitrogen for early rapid growth.
- Phosphate to supply the energy for early growth and development, especially root mass.
- Manganese for its role in the structure of photosynthetic proteins and enzymes.
- Zinc for enzyme reactions, early growth and vigour.
Tillering
- Nitrogen for leaf development and size, increasing tiller number per plant.
- Manganese for its role in the structure of photosynthetic proteins and enzymes.
Stem Extension
- Nitrogen for large leaves, rapid growth and development.
- Phosphate to supply the energy for growth and development.
- Potassium for plant water regulation and structural integrity.
- Sulphur for yield and quality improvements.
- Manganese for its role in the structure of photosynthetic proteins and enzymes.
- Zinc for enzyme reactions, nitrogen metabolism, and protein synthesis
- Copper for enzyme activity, chlorophyll production and seed production.
Flag Leaf and Grain Filling
- Nitrogen for higher yields through green leaf duration, grain site survival, grain size and protein levels.
- Magnesium for green leaf duration.
- Phosphate for dry matter remobilisation for yield improvements.
- Boron for pollen viability
- Zinc for grain protein.
