Interpretive Summary: Garrison creeping foxtail can increase the forage yield of wet meadows. However, tillage and subsequent seeding establishment on wet meadows is often difficult. This study examined the potential of establishing Garrison with the use of the herbicide glyphosate followed by no-till planting. Garrison was successfully established and increased forage yield, however, because of Garrison's earliness, crude protein of the forage was decreased. This research indicates that growers can successfully and economically plant Garrison creeping foxtail, increasing the production of wet meadows.
Technical Abstract: Garrison creeping foxtail can increase the forage yield of wet meadows. However, tillage on heavy-textured soils and thick sod mats often associated with wet meadows can be problematic. This study examined the potential of establishing Garrison with the use of herbicides and no-till planting. Garrison was no-till drilled into a wet meadow using three treatments. One treatment was herbicide control of existing vegetation in the entire plot area, in the second treatment herbicide was applied in bands and seed planted in the resulting strips, and the third treatment involved directly seeding into the meadow without any herbicide control. Establishment, forage yield and quality, and percent of forage yield comprised of Garrison were evaluated. Yield and establishment frequency and percent forage comprised of Garrison was highest when the entire plot was treated with herbicide. Garrison frequency was negatively correlated (r=-0.86) with crude protein. Direct seeding resulted in very little Garrison establishment and was considered a failure. Use of inexpensive herbicides and no-till planting can aid in establishing Garrison creeping foxtail in wet meadows.
