Interpretive Summary: A ban on open-field burning of post-harvest residue of grass seed production fields has been implemented in Washington, and restrictions are in place in Idaho and Oregon, USA. Our previous research showed that without post-harvest burning of residue, bluegrass seed yield decreased over time (Johnson et al., 2003). This has forced grass seed growers in the Pacific Northwest to use shorter rotations to maintain economically viable seed yields. What are needed are bluegrasses that will maintain high seed yield over several years without field burning of post-harvest residue. In a multi-year study we previously identified germplasm that had improved seed production without burning (Johnston, 2000). This germplasm needs long-term seed yield trials and turfgrass evaluations. Ultimately, bluegrasses that can be successfully grown for multiple harvests without burning will be released to grass seed growers in the Pacific Northwest, USA.
