It has been demonstrated that improved cultivars of seeded common bermudagrass (Cynodon dactylon L. Pers) can be dormant seeded during the winter, and this approach provides turf managers with an alternative means to renovate damaged areas of turf. However, bermudagrass golf courses and sports fields are often overseeded with a cool- season grass during dormancy, and the overseeded grass may prevent or delay establishment of the dormant seeded bermudagrass. While overseeding with a cool-season turfgrass is a well-accepted practice in the turf industry, the overseeded turf can negatively affect the dormant bermudagrass. Dormant seeding bermudagrass has been shown to be an effective means to renovate turf areas that have been thinned due to excessive wear and traffic. Unfortunately, in many turf situations, the field may still be receiving traffic from play while seedlings are germinating and the competition from an overseeded turf may prevent germination altogether. In the transition-zone, improved cultivars of common bermudagrass are becoming increasingly popular. Recent studies suggest that low light conditions can significantly reduce germination, but there has been limited work on the light requirements for emergence of seeded bermudagrass.

520 $a It has been demonstrated that improved cultivars of seeded common bermudagrass (Cynodon dactylon L. Pers) can be dormant seeded during the winter, and this approach provides turf managers with an alternative means to renovate damaged areas of turf. However, bermudagrass golf courses and sports fields are often overseeded with a cool- season grass during dormancy, and the overseeded grass may prevent or delay establishment of the dormant seeded bermudagrass. While overseeding with a cool-season turfgrass is a well-accepted practice in the turf industry, the overseeded turf can negatively affect the dormant bermudagrass. Dormant seeding bermudagrass has been shown to be an effective means to renovate turf areas that have been thinned due to excessive wear and traffic. Unfortunately, in many turf situations, the field may still be receiving traffic from play while seedlings are germinating and the competition from an overseeded turf may prevent germination altogether. In the transition-zone, improved cultivars of common bermudagrass are becoming increasingly popular. Recent studies suggest that low light conditions can significantly reduce germination, but there has been limited work on the light requirements for emergence of seeded bermudagrass.
520 $a Therefore, the objectives for this research were to: (1) determine if dormant seeding into a stand of overseeded turf could be an effective means of establishment, (2) determine how different mowing heights and traffic treatments affected germination of dormant seeded bermudagrass, (3) determine how reduced light affected germination and emergence of three bermudagrass cultivars, including Transcontinental, Riviera, and SR-9554. Bermudagrass establishment was improved by herbicide application, but was not affected by seeding date. Glyphosate applied before seeding and foramsulfuron applied in early summer provided the highest bermudagrass coverage compared to the other herbicide treatments. Establishment of seeded bermudagrass into an overseeded stand of perennial ryegrass turf was improved with herbicide use, regardless of the seeding date Bermudagrass germination and establishment was almost non-existent in overseeded turf area and was not enhanced by any of the mowing height or traffic treatments. Low light levels significantly reduced the emergence of all cultivars. However, the emergence of Transcontinental and Riviera were more inhibited by low light levels than SR-5994. Therefore, turf managers can have a successful establishment in an overseeded athletic field or fairway if competition is removed from the existing stand of turf.
