For winter wheat, what split‑nitrogen strategy at green‑up and Feekes 5 gave you the best protein or yield, and how did you set rates using soil nitrate tests or NDVI imagery? Can you share one field example where adjusting the second shot by weather forecast or using a nitrification inhibitor changed lodging or standability?

A split-nitrogen strategy in winter wheat production can enhance both protein content and yield by applying nitrogen at green-up (Feekes 3) and again at Feekes 5. Appropriate nitrogen timing and rates are crucial; insufficient nitrogen limits yield while excessive amounts can cause risky vegetative growth. Soil nitrate tests help determine existing nitrogen levels, guiding targeted applications to optimize growth and grain quality.
