I can remember a time when nitrogen was applied to winter wheat in February. Researchers have found that this is not a great idea. There is some discussion about split application in wheat. In my mind DAP applied in the fall constitutes the first application of nitrogen. If the DAP is applied later in the fall, cold weather will help preserve the nitrogen for spring growth. The early boost of nitrogen can increase tillering. It is much more efficient to apply nitrogen later in the growing season. Nitrogen can be applied well into April, putting on the crop when it is most needed. Pioneer Seed looks at nitrogen on wheat and refers to Illinois research.
