| Abstract/Contents: | "Poa supina has shown potential for athletic fields due to an aggressive stoloniferous growth habit. The objective of this study was to evaluate seeding mixtures of Poa supina 'Supra' (supina bluegrass) 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-1 yr⁻¹ and high: 30 g N m⁻¹ 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 (Nm) was also determined prior to and during traffic applications. Results indicate that increased traffic increases the aggressiveness 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 Poa supina had the highest turfgrass cover and shear strength, indicative of the importance of the presence of Poa pratensis in these mixtures. The results suggest, seeding a mixture of only 5 or 10% P. supina is enough to increase the P. supina composition to dominate the stand while maintaining acceptable turfgrass shear strength." |
