| Abstract/Contents: | "Bermudagrass is widely used on athletic fields because of its tolerances to drought, heat, and wear. The improved cold to lerance in some newer varieties of bermudagrass, such as 'Patriot', are allowing use of bermudagrass in athletic fields further north than in the past. The most common methods for establishing bermudagrass are: seeding, sprigging, and sod. Sprigging remains the most common approach due to availability and costs issues. Bermudagrass can be slow to establish from sprigs when compared to sod. Sand- based field construction is more common in recent years owing to improved drainage and compaction resistance with sand-based media. Due to costs of transportation, sand for field construction is typically limited to local quarries. In several instances, Virginia Tech researchers have observed slow establishment rates on white sand. We hypothesized that topdressing color could have an influence on the establishment rate. Therefore, a study was conducted to evaluate bermudagrass establishment when topdressed with particles of several colors and textures. A field trial was established July 19, 2007 on sprigged 'Patriot' bermudagrass at Virginia Tech's turfgrass research cent er with each plot ranging from 20 to 30% bermudagrass cover. The trial area was constructed to simulate Worsham Field with respect to drainage, irrigation, and sand-based growing media with the exception that a modular substructure was not installed. The study was established as a randomized complete block design with six treatments and three replic ations. Two particle sizes included sand between 0.05 and 2 mm diameter and Turface™ between 6 and 9 mm diameter. The six treatments were: brown Turface™, green Turface™, red Turface™, brown sand, white sand, and black sand each uni formly applied to a depth of 3.2 mm in 1.2 by 1.8 m plots. Starting July 19, 2007 weekly ratings were taken for percentage bermudagrass cover using a 100-grid count and by visual estimation. Prior to bermudagrass dormancy on October 10, 10-cm diameter core samples were removed from each plot, dried, and weighed to determine biomass of stolons and leaves. The percent change of cover based on the 100-grid count revealed that plots treated with white sand actually displayed equivalent or faster establishment rates compared to other topdressing materials. However, visual percentage bermudagrass cover ratings revealed that plots treated with green Turface™ displayed the fastest establishment rates. Discrepancies between grid counts and visual estimations probably occurred due to high contrast between turfgrass tissue and white sand compared to the low contrast between turfgrass tissue and green Turface™. Late-season biomass of 'Patriot' bermudagrass wa s equivalent regardle ss of topdressing color during establishment and extrapolates to a range between 3.3 and 4.1 kg per square meter. Thus, white sand does not appear to actually deter bermudagrass growth but does leave the viewer with the impression that the bermudagrass is thin. This psychological effect should be considered as it could be the difference between praise and retribution for field managers." |
