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
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
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.

Evaluation Of Grazing Options During Summer For Growing Heifers – Year 3, Jaymelynn K. Farney, Larissa Muniz, Harley Allen
Kansas Agricultural Experiment Station Research Reports
Developing methods to provide high quality forage through most of the year is important for cattle operations. The purpose of this study was to determine forage management options to offset the summer “slump” with fescue. Four grass pasture treatments (10 pastures total; 4 acres each) were used in a completely randomized design and stocked with growing heifers (n = 49; initial wt 461 ± 65 lb). Pasture treatments consisted of novel fescue (FES), crabgrass (CRAB), bermudagrass (BERM), and sorghum-sudan interseeded into novel fescue (SS-FES). Heifers were weighed and they grazed pastures from May to September. Heifers on FES were continuously …

Bermudagrass Fertility Trial In Southeast Kansas, 2020, D. Helwig, M. Haywood, J. K. Farney, B. C. Pedreira, G. F. Sassenrath
Kansas Agricultural Experiment Station Research Reports
In 2020 a bermudagrass fertility study was conducted at the K-State Research and Extension experiment station outside of Columbus, KS. The purpose of the study was to simulate forage producer practices of managing bermudagrass and determine how each practice affects forage production and quality. Addition of fertilizer, and mowing were tested to determine the impact on forage biomass production and quality. Fertilizer increased both biomass production and forage quality. However, greater improvements in forage quality were observed by mowing the bermudagrass.
Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Masters Theses
Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas
Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas
Kansas Agricultural Experiment Station Research Reports
Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in a bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod, and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen). Use of legumes in wheat-bermudagrass pastures did …

Enhanced Efficiency Nitrogen Formulation Effect On Grass-Legume Pasture Productivity, Kathryn Marie Payne
Enhanced Efficiency Nitrogen Formulation Effect On Grass-Legume Pasture Productivity, Kathryn Marie Payne
Theses and Dissertations--Plant and Soil Sciences
The use of nitrogen (N) fertilizer is generally restricted on mixed species forage systems due to its stimulatory effect on grasses which increases competition with legume species. Reduced legume growth from this competition can compromise forage nutritive value and prospective yields. The controlled-release nature of several enhanced efficiency fertilizer N products holds the potential to improve legume persistence in mixed species pastures while providing supplemental N required by the grass component. The studies contained in this dissertation evaluated the effect of different enhanced efficiency N formulations (ATU, ESN, methylene urea, SuperU, and a 75% ESN: 25% urea blend) and untreated …

Including Legumes In Wheat-Bermudagrass Pastures, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
Use of legumes in wheat-bermudagrass pastures did not affect summer cow gains in 2018. Forage availability was greater (P<0.05) where nitrogen (N) alone was used than where crimson clover and ladino clover were used in the Legume system. Estimated forage crude protein (CP) was similar (P>0.05) for the Legume and Nitrogen systems.

Integrated Strategies For Controlling Warm-Season Turfgrass Weeds, Matthew Thomas Elmore
Masters Theses
Herbicidal inhibitors of 4-hydroxyphenylpyruvate dioxygenase (HPPD) such as mesotrione, topramezone and tembotrione were evaluated in greenhouse experiments for activity against bermudagrass. While topramezone and tembotrione exhibited greater activity than mesotrione, none of these herbicides provided acceptable bermudagrass control. These herbicides reduced leaf tissue chlorophyll and carotenoid pigment concentrations in bermudagrass. Changes in turfgrass pigmentation were quantified using HPLC analogy as well as evaluations of visual bleaching and measurements of chlorophyll fluorescence yield (Fv/Fm). Results indicated that these more expeditious methods of evaluating HPPD-inhibiting herbicide activity (visual evaluations and Fv/Fm) cannot be used …
