Abstract/Contents:"Legislation over the past decade has reduced the number of grass seed acres that can be burned. As a result, there has been an increase in the amount of viable annual bluegrass seed, a serious contaminant of perennial ryegrass fields in the Willamette Valley of Oregon. Two field trails were established to determine the impact of these different residue management options on annual bluegrass germination. Other factors evaluated were soil moisture, yield, and seed contamination at harvest. The experimental design was a randomized complete block with three treatments and four replications. The treatments consisted of full straw, bale/flail, and vacuum sweep. Annual bluegrass germination was significantly lower in the vacuum sweep treatments than the full straw or bale/flail treatments (p-value: 0.001 and 0.002, respectively), but there was no difference between the full straw and the bale/flail treatments (p-value: 0.73) at Site 1. At Site 2, annual bluegrass germination in the vacuum sweep treatment was significantly lower than the bale/flail treatment (p-value: 0.01). However, the full straw was not different from the bale/flail or the vacuum sweep treatments (p-value: 0.30 and 0.12, respectively). The moisture levels among treatments were different over time for Site 1 but not Site 2 (p-value: 0.04 and 0.62, respectively). Yields and seed contamination was not different for each site."
