| Abstract/Contents: | "Poa supina (supina bluegrass) has shown potential for athletic fields due to an aggressive stoloniferous growth habit. The objective of this study was to evaluate seeding mixtures of P. supina `Supra' and P. pratensis `Touchdown' (Kentucky bluegrass) under varying fertility and traffic treatments. Six seeding mixtures of P. supina and P. pratensis (0, 5, 10, 25, 50, and 100% P. supina) were established as whole plots on a sand based root zone mix in June 1995. Nitrogen fertility (low: 20 g N m-2 yr-1 and high: 30 g N mT-2 yr-1) and traffic, using the Brinkman Traffic Simulator, were stripped over these mixtures. Plant counts to determine species composition were done in the spring of each year (1997-2000). Turfgrass cover (% cover) and shear resistance (N m) was also determined prior to and during traffic applications. Results indicate that increased traffic increasess the competitiveness of P. supina; by 2000 the trafficked plots seeded with only 5 and 10% P. supina were 99 and 96% P. supina. Trafficked plots seeded with 0 and 5% of P. supina had the highest turfgrass cover and shear strength, indicative of the importance of the initial presence of P. pratensis in these mixtures. The results suggest seeding a mixture of 5-10% P. supina with P. pratensis is enough to increase the P. supina composition to dominate the stand while maintaining acceptable turfgrass shear strength." |
