Nitrogen Management Strategies for Winter Wheat Yield and Grain Protein Improvement in Southeastern Colorado

IPNI-2013-USA-CO14

There is an increasing demand for high quality wheat as the baking industry requires adequate protein levels for their products. Frequently, wheat with higher grain protein is marketed at a premium, and price deductions are incurred for low protein wheat. Protein premiums and penalties have increased the interest among wheat growers in producing high quality wheat that meets the market standard and increases profits. Read more

Interpretive Summary

Nitrogen (N) fertilizer management affects both wheat grain yield and protein content. Grain protein can often be improved by N fertilizer topdressed later in the season. In regions where a premium is paid for protein, growers are more likely to adjust N management practices to affect grain protein.

Nitrogen fertilizer management affects both wheat grain yield and protein content. Grain protein can often be improved by topdressing N later in the season. Where a premium is paid for protein, growers are more likely to adjust N management practices to affect grain protein. Colorado wheat production has mostly been hard red winter wheat (HRWW), but in recent years some growers have been given incentive to plant more hard white winter (HWWW), where a premium is paid for grain protein.

Colorado wheat production has traditionally been hard red winter wheat (HRWW), but in recent years some growers have been given incentive to plant more hard white winter (HWWW), where a premium is paid for grain protein.

Nitrogen fertilizer management is an important factor affecting wheat grain yield and protein content. The protein content in grain can often be improved by a N fertilizer topdress application later in the season. Where a premium is paid for grain protein, growers are more likely to adjust N management practices to improve this important quality parameter. Wheat production in Colorado has traditionally mostly been hard red winter wheat.
