How to increase wheat yield
The two key yield components of wheat are grain numbers per unit area, and the individual grain weight. High yields come from achieving the correct leaf and shoot numbers, maintaining a green leaf canopy, increasing grain numbers/ear and grain size.
A balanced crop nutrition program including all macro and micro nutrients is essential to help manage all of these components.
Macronutrient uptake in winter wheat
Nitrogen and potassium are the nutrients required in the highest quantity for maintaining high wheat yields. Typically a wheat crop will a utilise 60% more potassium than nitrogen with the requirements for phosphate and sulphur being less but still significant.
The phosphate requirement, on the other hand, is similar to sulphur. It is during rapid spring growth that the demand for all macronutrients occurs.
Removal differs from field to field but typically a 10t/ha wheat crop can remove over 230kg/ha of nitrogen and 57kg/ha of potassium in the grain alone.
Micronutrient uptake in winter wheat
A balanced crop nutrition strategy is essential and should also include secondary and micronutrients which are essential elements in achieving high yields.

How to maintain wheat green leaf canopy
The key to achieving high wheat yields, having established the correct canopy structure, is to maintain the green area right through to the final grain filling period, capturing as much of the incident light as possible and converting it to yield.
How to increase wheat grain size and weight
Wheat grain size is strongly influenced by plant nutrition particularly during the important grain filling period. Nitrogen, phosphate, potassium, magnesium and zinc are particularly important.
How to increase wheat protein content and quality
Nitrogen and sulphur both influence grain protein content and quality. Nitrogen should be applied when the plant can still incorporate the nitrogen into its grain, and sulphur levels need to be adequate to ensure this does not limit nitrogen use.
How to increase wheat grain specific weight
Grain specific weight is a measure of the density of the grain. Specific weight is predominantly a genetic trait of varieties, but poor crop nutrition and application can reduce specific weight.
