Cynodon Dactylon Control In Conservation Tillage Systems, A Rios, J M. Sanz
Cynodon Dactylon Control In Conservation Tillage Systems, A Rios, J M. Sanz
IGC Proceedings (1997-2023)
Bermudagrass (Cynodon dactylon L. PERS.) is the most important weed in Uruguay. With the development of conservation tillage systems, chemical control of bermudagrass becomes essential. The objective of this research was to evaluate, in a long term integrated program, bermudagrass chemical control during the first year of a pasture. Application of glyphosate and no-tillage seeding of the pasture took place during fall. A 70% reduction of underground part of the weed was detected. The chemical control, together with a conservation tillage system and an adequate pasture management allowed an important reduction in bermudagrass level for the first year pasture. …
Stockpiling Perennial Warm-Season Grasses: Bermudagrass Example, J. A. Jennings, K. J. Simon
Stockpiling Perennial Warm-Season Grasses: Bermudagrass Example, J. A. Jennings, K. J. Simon
IGC Proceedings (1997-2023)
Winter feeding is the largest expense of maintaining a beef herd in terms of money and time. Stockpiled bermudagrass is an effective practice for reducing winter feeding expenses and extending the grazing season. Stockpiling forage is the practice of accumulating forage growth intended for grazing in a later season. In Arkansas, bermudagrass is stockpiled from early August to late October and is grazed from late October through mid-December. Rainfall during late summer can be erratic with high risk of drought stress, but an early start date maximizes the opportunity for acceptable stockpiled forage yield. Therefore, stockpiling bermudagrass should begin by …
In Vitro Methane Production From Heifers Offered Four Bermudagrass Cultivars, A. R. Hines, W. G. Bergen, M. K. Mullenix, S. L. Dillard, T. R. Callaway, W. B. Smith
In Vitro Methane Production From Heifers Offered Four Bermudagrass Cultivars, A. R. Hines, W. G. Bergen, M. K. Mullenix, S. L. Dillard, T. R. Callaway, W. B. Smith
IGC Proceedings (1997-2023)
Though bermudagrass (Cynodon dactylon [L.] Pers.) is one of the predominant warm-season perennial forage supporting the southeastern United States livestock production systems, little is known about its influence on parameters of ruminal metabolism, including carbon loss as methane. With the multitude of cultivars of this grass that have been developed and released, one may question whether the physiological cultivar differences will manifest varying results in digestive efficiency and subsequent methane emissions. Thus, the objective of this study was to evaluate in vitro methane (CH4) production as influenced by four bermudagrass cultivars. Ruminally-fistulated heifers (n = 4) were assigned randomly …
Growth Characteristics Of Ecotype Superior Line Of Bermudagrass And Development Of Its Rdna Markers, Y. W. Rim, K. Y. Kim, M. J. Kim, B. R. Sung, Y. C. Lim, E. S. Chung
Growth Characteristics Of Ecotype Superior Line Of Bermudagrass And Development Of Its Rdna Markers, Y. W. Rim, K. Y. Kim, M. J. Kim, B. R. Sung, Y. C. Lim, E. S. Chung
IGC Proceedings (1997-2023)
Interest in turfgrass has steadily increased in Korea since the 2002 Korea-Japan World Cup . Use of zoysiagrass (Zoysia japonica L.) has been limited due to its slow recovery, low shoot density, short green period and low wear tolerance during dormancy (Lee et. al., 1999). Bermudagrass has high quality and fast recovery, but has low cold tolerance (Richardson et. al., 1978). This research compared the growth characteristics of a superior line of bermudagrass, named as Joyspy with other standard cultivars and to develop its rDNA markers.
Effect Of Supplementation On Performance And Faecal Particle Size Distribution For Yearling Horses And Weaned Calves Grazing Coastal Bermudagrass, F. M. Rouquette Jr., K. N. Grigsby, D. K. Hansen, G. D. Potter, W. C. Ellis
Effect Of Supplementation On Performance And Faecal Particle Size Distribution For Yearling Horses And Weaned Calves Grazing Coastal Bermudagrass, F. M. Rouquette Jr., K. N. Grigsby, D. K. Hansen, G. D. Potter, W. C. Ellis
IGC Proceedings (1997-2023)
Supplements are often fed, especially to horses, without realistic expectations of the magnitude of performance response nor knowledge of biological or economic efficiencies of supplementation. The objectives of this experiment were to compare performance of weaned calves vs yearling horses grazing 'Coastal' bermudagrass [Cynodon dactylon (L.) Pers] (COS) pastures with and without a protein-energy supplement, and to assess faecal particle size distribution for both calves and horses to document digesta dynamics.

Arkansas Agricultural Experiment Station Research Series
Rapid technological changes in crop management and production require that the research efforts be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts. Additionally, soil-test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.
Evaluation Of Off-Type Grasses In Interspecific Hybrid Bermudagrass [Cynodon Dactylon (L.) Pers. X C. Transvaalensis Burtt-Davy] Putting Greens, Eric Hall Reasor
Evaluation Of Off-Type Grasses In Interspecific Hybrid Bermudagrass [Cynodon Dactylon (L.) Pers. X C. Transvaalensis Burtt-Davy] Putting Greens, Eric Hall Reasor
Doctoral Dissertations
The economic impact of the golf industry in the United States (U.S.) in 2011 was estimated to be $176.8 billion. Interspecific hybrid bermudagrasses [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] are some of the most widely utilized grasses on golf courses throughout tropical, subtropical, and temperate climates. In 2007, bermudagrass was grown on 80% of putting green acreage in the southern U.S. ‘Tifgreen’ and ‘Tifdwarf’ were two of the first widely established cultivars on putting greens, but their genetic instability led to the occurrence of phenotypically different off-type (OT) grasses. Several OT grasses were selected and released as …
Rooting Characteristics And Antioxidant Pigment Responses Of Three Hybrid Bermudagrass [Cynodon Dactylon (L.) Pers. × Cynodon Transvaalensis Burtt- Davy] Cultivars Exposed To Drought, Cory Alan Yurisic
Masters Theses
With recent changes in global climate, water use and its conservation have become important topics of discussion. Turfgrasses for lawns, parks, and other recreational areas are often perceived negatively due to the need for irrigation. The identification of turfgrasses possessing an improved ability to withstand water deficit is an important goal in science to curb irrigation requirements in the landscape. Newly released cultivars of hybrid bermudagrass (C. dactylon L. x. C. transvaalensis Burtt-Davy) have demonstrated improved tolerance to stresses such as cold, traffic, and water deficit; however, drought resistance mechanisms of these new cultivars have been largely uninvestigated. Drought …
