Abstract/Contents:"In order to conduct turfgrass weed research in the field, an evenly distributed weed population in a known species/variety of turfgrass is desirable. Weeds in turfgrass sites tend to germinate and grow in areas of lesser competition. Therefore, the weed population density is often random and inconsistent within any site, forcing weed scientists to conduct research on sites consisting of large areas. Additionally, control ratings are often variable from year to year, due to varying weed populations. Such problems were the rational for establishing turfgrass weed research sites at the Valentine Turfgrass Research Center, Penn State University, University Park, PA that would, hopefully, address some of these problems. Six turfgrass weed research sites were established starting in 1999. A broadleaf weed/perennial ryegrass (Lolium perenne) research site was established in July of 1999. A seedbed was prepared and planted with 2 lbs/M `SR4200' perennial ryegrass and 44 lbs/A dandelion (Taraxacum officinale). Following the initial seeding, subsequent overseedings of this research site have totaled 301 lbs/A dandelion seed, 246 lbs/A white clover (Trifolium repens) seed, and 64.5 lbs/A of buckhorn plantain (Plantago lanceolata) seed to date. A complete fertilizer is applied at 1.0 lb N/M to areas where product evaluations are conducted in the current growing season. The research site was mowed three times per week at 1.0 inch. Two smooth crabgrass (Digitaria ischaemum) research sites were established in July of 1999. Seedbeds were prepared and seeded with SR4200 perennial ryegrass seed at 2 lbs/M and `Midnight' Kentucky bluegrass (Poa pratensis) seed at 3 lbs/M. The research sites are annually overseeded with 1 lb/M smooth crabgrass seed in the fall. The smooth crabgrass site maintenance has been the same as the broadleaf weed research site. A minimum of two years of overseeding the broadleaf weed and smooth crabgrass sites are required prior to product evaluation. A ground ivy (Glechoma hederacea) research site was established in 1999. Each growing season 4.25 inch diameter plugs of ground ivy are planted into a stand of SR4200 perennial ryegrass in groups of four that form a 12 inch square pattern. The 4,000 ft2 research area has received over 3,000 ground ivy plugs to date. Annual bluegrass (Poa annua) seed was harvested from the numbers nine and ten fairways of the original Penn State White Golf Course, University Park, PA prior to renovation. The harvested seed was planted at the Valentine Turfgrass Research Center at the rate of 1.0 lb/M in July of 2001. On a separate site, `Winter Play' rough bluegrass (Poa trivialis) was seeded at 3 lbs/M in July of 2001. Both research sites are maintained at 0.5 inch height with a five gang reel mower, and receive one application of 3 lbs N/M from IBDU in late fall, early winter, or prior to spring greenup. Additionally, fertilizer applications of 0.5 lb N/M from urea were applied as needed throughout the growing season to maintain growth and color."
