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

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 …

Effects Of Supplementing Corn Silage To Fall-Calving Heifers And Cows Grazing Bermudagrass And Calf Performance And Physiology, J. Wyatt L. Banks, Jaymelynn K. Farney, Karol E. Fike, Jason M. Warner

Kansas Agricultural Experiment Station Research Reports

The objective was to test the effect of supplemental feeding on cows grazing bermudagrass pastures on cow-calf performance and pasture management. In a completely randomized design, (n = 24) primiparous and multiparous Angus-based cross cows were allocated to bermudagrass pasture with one of two levels of supplemental feeding (non-supplemented or supplemented at 1% of BW on a DM basis of corn silage). Each treatment consisted of (n = 4) pastures stocked with three cows of different ages, a young (first-calf heifer), middle-aged (3-5 yrs.), and old (≥ 6 yrs.) cow, each averaging 155 ± 14 d of gestation at turnout. …

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

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 …

2019 National Turfgrass Evaluation Program Bermudagrass Test: 2022 Data, Linda R. Parsons, Jason Griffin

Kansas Agricultural Experiment Station Research Reports

Kansas represents the northernmost region in the central United States where bermudagrass (Cynodonspp.) can be successfully grown as a perennial turfgrass. Historically, few cultivars that have both acceptable quality and adequate cold tolerance have been available to local growers. Because new introductions are continually being selected for improved hardiness and quality, both seeded and vegetative types need regular evaluation to determine their long-range suitability for use in Kansas.

Perennial Warm-Season Grass Forages Impact On Cow-Calf Profitability In The Fescue Belt, Kyle A. Brazil, Patrick D. Keyser, Andrew P. Griffith, Christopher N. Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

Incorporating a perennial warm- season grass (WSG) into tall fescue (Lolium arundina-ceum [Schreb.] Darbysh.) forage systems in the fescue belt can help avoid the effects of fescue toxicosis on beef cattle (Bos taurus) reproduction and animal performance and provide forage during summer when fescue production is low. However, little information is available on the economics of incorporating WSG into fescue-based forage systems. We developed a simulation model to compare profitability of three forage systems—100% tall fescue, 70% tall fescue/30% bermudagrass (Cynodon dactylon), and 70% tall fescue/ 30% switchgrass (Panicum virgatum)—while also comparing spring- …

Economic Injury Level For Bermudagrass Stem Maggot (Diptera: Muscidae) In Bermudagrass Forage Production In Texas, V. Corriher-Olson, A. Knutson, F. Mitchell

IGC Proceedings (1997-2023)

The bermudagrass stem maggot, Atherigona reversura Villeneuve, was first reported damaging bermudagrass Cynodon dactylon (L.) Pers grown for forage in 2010 in the southeastern US. Damage results from individual larvae feeding internally on the vascular tissue just above the terminal node of the grass stem. Damage slows plant growth and reduces forage accumulation. To address the need for economic guidelines to manage this new pest, the relationship between the percent of stems damaged by bermudagrass stem maggot and forage yield was measured in commercial bermudagrass hay fields in northcentral Texas during 2016 and 2017. The slope of the linear regression, …

Dairy Cow Performance On Pasture-Based Feeding Systems And In Confinement, Renato S. Fontaneli, Lynn E. Sollenberger, C. R. Staples

IGC Proceedings (1997-2023)

Interest in grazing systems is growing among farmers in the USA as a means of reducing feed costs for lactating dairy cows. An experiment was conducted near Gainesville, FL to compare milk production and composition and milk income minus feed costs from two pasture-based systems with those of a conventional confinement housing system over a 276-d period. System 1 was based on a mixture of rye (Secale cereale L.), annual ryegrass (Lolium multiflorum Lam.), crimson clover (Trifolium incarnatum L.), and red clover (Trifolium pratense L.) during the winter-spring seasons and pearl millet (Pennisetum glaucum [L.] …

Spring Regrowth And Steer Performance On Tifton 85 And Coastal Bermudagrass Pastures Following Sod-Seeding With Ryegrass, G. M. Hill, R. N. Gates

IGC Proceedings (1997-2023)

Effects of autumn sod-seeded ryegrass (Lolium multiflorum; cv. Passerel; 37.7 kg/ha) in bermudagrass pastures (Cynodon spp.; cv. Coastal and cv. Tifton 85) on grazing steer performance were determined. Ryegrass was sod-seeded in three of six .81 ha pastures of each bermudagrass. Forage height was adjusted to10 cm during spring. Stocking rates were unaffected by ryegrass in Tifton 85 pastures, but they were higher (P < .05) for Tifton 85 than Coastal. Ryegrass increased tester steer average daily gains by 34% (.86 vs .64 kg/day; P < .01), and gain/ha by 26% (387 vs 306 kg/ha; P < .05). Higher stocking rates resulted in 22% more grazing days (515 vs 421 days/ha; P < .01), and 30% higher gain/ha (391 vs 301 kg/ha; P < .05) for Tifton 85 than Coastal pastures. Ryegrass did not affect stocking rates or steer performance on Tifton 85, but it depressed both on Coastal pastures.

Moving Warm-Season Forage Bermudagrass (Cynodon Sp.) Into Temperate Regions Of North America, W. F. Anderson, L. Baxter, D. Hancock, R. N. Gates, Esteban F. Rios

IGC Proceedings (1997-2023)

Warm-season (C4) perennial grasses are grown over millions of hectares in the Southeastern United States. These grasses produce optimal growth at 30 to 38°C diurnal temperature. Bermudagrass (Cynodon sp.) has been adopted as the preferred forage for many livestock and hay producers. Compared to other native and introduced warm-season perennial grass species, improved bermudagrass varieties produce high biomass with enhanced digestibility for ruminant grazing or feed. Until the 1930’s pastures in the region consisted of unimproved ‘common’ bermudagrass (Cynodon dactylon (L.) Pers.) that had been introduced earlier. However, in the early 20^th century, new germplasm, including stargrass …

Extended Daylength To Increase Fall/Winter Yields Of Warm-Season Perennial Grasses, P. Mislevy, T. R. Sinclair, J. D. Ray

IGC Proceedings (1997-2023)

Low forage production in fall/winter months is a severe limitation for dairy and beef cattle producers in the southeastern U.S. It was hypothesized that shrt daylengths during these months induce a physiological dormancy in grasses. Four grasses [Pensacola bahiagrass, Paspalum notatum Flugge; Tifton 85 and Florakirk bermudagrass, Cynodon dactylon (L.); Florona stargrass, C. nlemfuensis Vanderyst var. nlemfuensis] were subjected to extended daylengths during the winter/fall months in a field test. Pensacola bahiagrass and Tifton 85 bermudagrass showed especially dramatic increases in forage yield during the fall/winter season under the extended daylength. Genetic elimination of daylength sensitivity in these grasses …

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

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

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 …

Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer
