Factors Affecting Protein Content of Wheat
N supply and
In-crop N where crop demand exceeds soil supply
Early Seeding Date
Late Seeding Date
50 ppm base N
Under dry conditions, late N applications to soil may be unavailable
Foliar applications may allow N uptake by plant
greater advantage in drier areas?
