Role of Nutrients by Growth Stage in Oats

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.
