Abstract

Abstract: Athletic field managers often adjust agronomic practices according to the desires of coaches and athletes. One such agronomic practice often adjusted is mowing height. In an attempt to have athletes run faster, field managers are persuaded to reduce mowing height, thereby reducing potential friction from the surface on an athlete. With newer bermudagrass [ Cynodon datylon (L.) Pers.] and hybrid bermudagrass [ Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy] cultivars, maintaining a field at reduced mowing heights is much easier to achieve without apparent negative effects on surface performance. However, these expected effects have not been verified through rigorous research and are solely dependent on anecdotal data. The objectives of this study were to compare traffic tolerance of four hybrid bermudagrass cultivars ‐ 'Latitude 36 Turf Bermudagrass' (Latitude 36) and 'Northbridge Turf Bermudagrass' (Northbridge), 'Tifway', and 'Patriot' ‐ and two bermudagrass cultivars ‐ 'Riviera', and 'Hollywood' ‐ and determine the effect of mowing height on traffic tolerance. Treatments were arranged in a randomized complete block design with eight replications. Measurements of percent green cover, surface hardness, and peak rotational traction were collected before, during, and after simulated traffic. Latitude 36 and Northbridge were more traffic tolerant than any of the other cultivars tested. While there was not an interaction between cultivars and mowing height, the higher mowing height had greater traffic tolerance. Core Ideas: Cultivar selection is important to traffic tolerance. Changes in mowing height can impact traffic tolerance. Species and cultivars should be carefully selected based on surface performance expectations.
