Barley nutrient requirements
Barley nutrient requirements vary depending on the crop growth stage. Find out which nutrients are most important and the roles of nutrients at different barley growth stages.
Establishment
Nitrogen for early rapid growth.
Phosphate to supply the energy for early growth and development, especially root mass.
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
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
