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.
