Abstract/Contents:"Meadowfoam is an oil-seed crop that was developed by Oregon State University to be grown in the wet soils of the Willamette Valley. These soils have been used for several decades to produce seed of annual and perennial ryegrass and tall fescue. The lack of crop rotation and a restriction on field burning has resulted in dense populations of herbicide-resistant annual bluegrass. Meadowfoam could be an important alternative crop for Willamette Valley grass seed growers. Field trials were conducted in 1994 to 1995, 1995 to 1996, 1996 to 1997, and 1997 to 1998 to evaluate the effect of annual bluegrass on meadowfoam seed yield. Annual bluegrass was seeded at eight densities in each trial prior to drilling the meadowfoam seed. The annual bluegrass stand densities ranged from zero each year to as high as 826/ft2 in 1997 to 1998. Annual bluegrass did not greatly affect meadowfoam seed yield in any year except 1996 to 1997, when meadowfoam seed yield increased as annual bluegrass stand density increased. This increase may have been related to an infestation of Scaptomyza sp. fly which seemed to parasitize meadowfoam that was growing without annual bluegrass. These studies show that meadowfoam can be a successful crop in western Oregon grass seed fields even without an annual bluegrass control program."
