This project involves investigation of timing impacts on protein levels and quality in hard red winter wheat. It includes a nitrogen rate component, genetic interactions, and Near Infra Red technology evaluation of nitrogen needs.

Excellent progress has been made on this project this year. Four small plot and 21 field scale sites were established in the fall of 2007, and harvested in the summer of 2008, far exceeding expectations. Yields, moistures, test weight, thousand kernel weight, soil nitrates and protein levels have all been completed, with evaluation of baking qualities pending. Data analysis is underway. Green seeker readings (nitrogen prediction tool) were taken at all field sites. This years data will be compiled with the 2007 data, and will give an excellent basis to move forward with into the final (2009) year.

This information may delineate the required management to deliver consistent high protein wheat into the huge market that demands this quality. Green seeker analysis may help to determine required nitrogen rates, improving nitrogen efficiency and limiting environmental impact.

If successful, this research could increase utilization of Ontario grown hard red wheat within the province, reduce the over supply of soft wheat, and replace western red spring with Ontario hard red winter. This would increase the potential profit of wheat production significantly; both through improved basis on soft wheat, increased acreage and utilization of hard wheat, and less environmental impact through more targeted nitrogen applications.

Initial data analysis indicates increased protein levels of 0.5 to one percent by post anthesis nitrogen applications.
