An Evaluation Of The Black Walnut- Tall Fescue Pasture-Management System, H E. Garrett, W B. Kurtz
An Evaluation Of The Black Walnut- Tall Fescue Pasture-Management System, H E. Garrett, W B. Kurtz
IGC Proceedings (1977-2023)
The economic and biological feasibility. of a black walnut-livestock-grazing multicropping-management regime bas been evaluated for comparison with a similar livestock-management regime conducted in the open. Pure tall fescue plots were established under open and black walnut-shade conditions. Forage yields on a dry-weight basis were estimated for a 3-year period. A concurrent grazing trial was coducted on similar sites using 1.2-ha plots. Black walnut seedlings were planted within the plots on a 3 x 12-m spacing and protected from grazing animals by electric fencing. The economic analyses of the alternate grazing systems were based on their respective present net worth and …
Stockpiling Of Cool-Season Grasses In Autumn, C T. Dougherty
Stockpiling Of Cool-Season Grasses In Autumn, C T. Dougherty
IGC Proceedings (1977-2023)
The practice of accumulating growth of cool-season grasses in the late summer and early autumn for subsequent grazing in late autumn and winter, known as stockpiling, has been widely accepted by beef cow-calf producers. The objectives of our study were to determine the growth characteristics of cool-season grasses in the autumn under nitrogen (N) fertilization and to investigate utilization of stockpiled forages. Tall fescue (Festuca arundinacea Schreb.) has many attributes that make it highly suited to stockpiling. On Maury silt loams, Kentucky 31 tall fescue accumulated 6,500 kg/ha of dry matter from 16 August 1979 to 12 December 1979 …
Increased Use Of Southern Piedmont Land And Climatic Resources By Interseeding Small Grains In Dormant Coastal Bermudagrass, S R. Wilkinson, J A. Stuedemann
Increased Use Of Southern Piedmont Land And Climatic Resources By Interseeding Small Grains In Dormant Coastal Bermudagrass, S R. Wilkinson, J A. Stuedemann
IGC Proceedings (1977-2023)
Experiments were conducted to assess interseeding small grains by no-till methods in dormant Coastal bermudagrass (Cynodon dacrylon [L.] Pers.) for forage, silage, grain, or beef production. Wheat (Triticum aestivum L.) was interseeded in Coastal bermudagrass (CBG) sod. Grain yields of 1,695 kg/ha reduced CBG yields 14%, and silage yields of 6.7 tons/ha resulted in a 5 % reduction in CBG yield. The nitrogen (N) requirements for tall fescue (Festuca arundinacea Schreb. L.) or rye (Secale cereale L.) interseeded in dormant CBG for 90 % of maximum yield were similar at 166 and 17 5 kg N …

Grazing Techniques For Evaluating Quality Of Forage Cultivars In Small Pastures, A G. Matches, F A. Martz, D A. Sleeper, R L. Belyea
IGC Proceedings (1977-2023)
Because plant beeders have few laboratory analyses of forage quality that are good predictors of animal performance when grazing pasture, • we studied the feasibility of grazing small pastures with cattle in order to detect possible forage-quality differences among cultivars of tall fescue (Festuca anmdinacea Schreb). Kentucky 31, Kenmont, Fawn, and Missouri 96 tall fescue cultivars and Kenhy, a Lolium-Festuca derivative, were grown in 0.47-ha pastures and grazed in separate periods ranging from 35 to 68 days during the spring, summer, and autumn of 1974-1976. Between grazing periods, cattle grazed a reserve pasture of the same cultivar. All test pastures …

Effect Of Level Of Nitrogen Fertilization Of Kentucky 31 Tall Fescue (Festuca Arundinacea Schreb.) On Brood-Cow Health, J A. Stuedemann, S R. Wilinson, H Ciordia, A B. Caudle
IGC Proceedings (1977-2023)
Studies were conducted to assess the long-term effects of nitrogen (N) fertilization of tall fescue on cow-calf performance and health problems, including grass tetany, fat necrosis, gastrointestinal parasitism, and nitrate poisoning. Kentucky 31 tall fescue pastures fertilized at three levels of N were grazed with Angus cows at 0.4 ha/cow on a year-round basis. Fertilization levels included high N (667 and 0 kg N/ha/yr from broiler litter in 1968-1974 and 1975-1977, respectively); moderate N (134 and 224 kg N/ha/yr from ammonium nitrate [NH4N03] in 1969 and 1970-1977, respectively); and low N (84 and 74 kg N/ha/yr from NH4N03 in 1972 …

Beef Production From Tall Fescue Treated With Mefluidide A Chemical Plant-Growth Regulator, T W. Robb, D G. Ely, C E. Rieck, S Glenn, L Kitchen, B P. Glenn, R J. Thomas
IGC Proceedings (1977-2023)
Mefluidide treatment of Kentucky 31 tall fescue (Festuca arundinacea Schreb.) in the spring will inhibit seed-head formation, maintain the forage in an immature and vegetative stage, and increase forage N and soluble-sugar content and in-vivo nutrient utilization in the ovine. Productivity of animals grazing mefluidide-treated tall fescue, however, has not been determined. The objective of this study was to evaluate agronomic characteristics of forage and productivity of yearling beef steers and heifers grazing mefluidide-treated (T) and nontreated control (C) pastures of Kentucky 31 tall fescue. Experimental pastures of Kentucky 31 tall fescue ( 4 replications at location I and one …
Role Of Alkaloids And Toxic Compounds In The Utilization Of Tall Fescue By Ruminants, J A. Boling, R W. Hemken, L P. Bush, R C. Buckner, J A. Jackson Jr, S G. Yates
Role Of Alkaloids And Toxic Compounds In The Utilization Of Tall Fescue By Ruminants, J A. Boling, R W. Hemken, L P. Bush, R C. Buckner, J A. Jackson Jr, S G. Yates
IGC Proceedings (1977-2023)
Tall fescue (Festuca arundinacea Schreb.) contains several alkaloids. Studies in our laboratory showed that perloline is a principal alkaloid in tall fescue during the summer and that concentration peaks at a time when cattle grazing tall fescue pastures frequently have severely reduced performance (summer syndrome or summer fescue toxicosis). The objectives of the following studies were (1) to determine the influence of perloline on in-vitro fermentation and in-vivo ruminant metabolism and (2) to determine the effects of two tall fescue strains selected for perloline concentration on performance of growing cattle and lactating dairy cows and on interrelationships with environmental …

Increasing Productivity And Extending Grazing Season Of Cynodon Pastures For Steers With N And Overseedings Of Trifolium And Festuca In The Southeastern U.S.A, H A. Fribourg, J B. Mclaren, R J. Carlisle
IGC Proceedings (1977-2023)
A series of grazing experiments has been conducted 80 km east of Memphis, Tennessee, since 1969 on fine-silty, mixed, ther mic, Typic Hapludalfs soils to evaluate productivity and quality of Cynodon pastures grown with N fertilizer or in combination with Festuca arundinacea and/or Ladino, TnJolium repens, and sometimes with T. pmtense, for growing beef steers. Pastures were grazed by the put-and-take system, and forage growth and consumption were determined by the cage-and-strip method. These experiments have shown that bermudagrass pastures can support many young beef animals for 5 months/yr if they are fertilized with N, can produce rapid gains in …
Effects Of Maturity And Environment On Amount And Composition Of Hemicellulose In Tall Fescue, S L. Fales, D A. Holt, C.S T. Daughtry, V L. Lechtenberg
Effects Of Maturity And Environment On Amount And Composition Of Hemicellulose In Tall Fescue, S L. Fales, D A. Holt, C.S T. Daughtry, V L. Lechtenberg
IGC Proceedings (1977-2023)
Seasonal changes in amount, compos1bon, and digestibility of fiber in vegetative tissues of forage grasses are usually associated with advancing tissue maturity. Our objective was to determine the relative effects of maturity and environment on amount and composition of hemicellulose in field-grown tall fescue (Festuca arundinacea Schreb.). Regrowth of identical chronological age was sampled weekly at different times during the growing season. Leaf samples were extracted with neutral detergent solution to isolate cell walls (NDF). The NDF was treated with 1.0 H2S0+ to remove and hydrolize hemicellulose. The hydrolyzates were analyzed for concentrations of xylose and arabinose, using …
Using Leaf-Area Expansion Rate To Improve Yield Of Tall Fescue, C J. Nelson, D A. Sleper
Using Leaf-Area Expansion Rate To Improve Yield Of Tall Fescue, C J. Nelson, D A. Sleper
IGC Proceedings (1977-2023)
Several physiological characters have been proposed for use in breeding programs for higher yield potential. Our objectives were to evaluate recurrent restricted phenotypic selection for developing populations of tall fescue (Festuca arundinacea Schreb.) for low and high rates of leaf-area expansion (LAE). Mter four cycles, LAE was 181 and 74 mm2/day for the high (H) and low (L) populations, respectively. It appeared that LAE changes in early generations were due largely to increased leaf elongation rate (LER) of the H populations, whereas later progress was due largely to decreased leaf width (L W) of the L populations. Overall, LER had …
Effects Of Defoliation On The Difference In Growth Between Large And Small Plants In Swards, Y Takasaki, H Oizumi, H Nojima
Effects Of Defoliation On The Difference In Growth Between Large And Small Plants In Swards, Y Takasaki, H Oizumi, H Nojima
IGC Proceedings (1977-2023)
Stands of alfalfa (Medicago sativa) become sparser as cutting frequency is increased (Takasaki, 1980), while stands of orchardgrass (Dactylis glomerata) or tall fescue (Festuca arundinacea) become denser as cutting frequency is increased (Jung et al., 1974; Ishida et al., 1971). It is assumed that defoliation of swards increases the difference in growth between individual plants and causes some of them to die in the case of alfalfa, whereas in those of orchardgrass or tall fescue defoliation decreases the difference in growth and relieves stand reduction. In order to prove this assumption two experiments were …
Some Trials To Establish A Mixture Of Tall Fescue And Bahiagrass In Warmer Region Of Kyushu, M Ueno, Y Sugimoto, M Hirata
Some Trials To Establish A Mixture Of Tall Fescue And Bahiagrass In Warmer Region Of Kyushu, M Ueno, Y Sugimoto, M Hirata
IGC Proceedings (1977-2023)
In order to extend growing season and to increase annual production of pastures in southern part of Kyushu where warm and humid summers alternate cold winters, authors attempted to seed a mixture of cool- and warm-season pasture species. Tall fescue (Festuca arundinacea) and bahiagrass (Paspalum notatum) were sown in spring and autumn to form monoculture and mixture swards. Tall fescue started growth earlier and produced maximum yield in spring, while bahiagrass yielded much during early summer to autumn. In the mixture, combined yield of two species was between two monocultures, but total annual yield was less …
Allelopathic Effects Of Tall Fescue On Germination And Seedling Growth Of White Clover Genotypes, G A. Rederson
Allelopathic Effects Of Tall Fescue On Germination And Seedling Growth Of White Clover Genotypes, G A. Rederson
IGC Proceedings (1977-2023)
Tall fescue (Festuca arundinacea Schreb.) and white clover (Trifolium repens L.) are commonly grown together in pastures of the southeastern USA. Allelopathy of tall fescue may reduce white clover germination and growth during establishment of the legume. The objective of this study was to determine if white clover genotypes differ in germination and initial growth in extracts of tall fescue leaves. Agar containing leaf extracts from tall fescue was used to test the germination and root growth of forty white clover genotypes. Significant differences were found between the genotypes for percent germination and root length score. Root length score …
Analysis Of Seed Production In Relation To Climatic Conditions In Tall Fescue Varieties, Shigeru Suzuki
Analysis Of Seed Production In Relation To Climatic Conditions In Tall Fescue Varieties, Shigeru Suzuki
IGC Proceedings (1977-2023)
Resulting from extensive efforts of breeding, our new registered varieties of forage crops show excellent performance in forage production under proposed areas of recommendation, but in general there are problems for seed production. In order to raise seed production or to find out better environments a regional seed production trial including several forage species was attempted. Under wide range of natural conditions, plant characteristics especially panicle and seed properties were recorded besides seed yield for two to three harvest years. Because response of these traits in relation to environmental conditions of experimental sites was of primary concern, soil conditions and …

Etude Comparative De Deux Varietes De Fetuque Elevee De Qualite Differente Conduites En Paturage Continu Avec Vaches Laitieres, J C. Emile, M Gillet, L Huguet
IGC Proceedings (1977-2023)
Dans des essais anterieurs (Gillet et al., 1986 et 1989), nous avons mis en evidence chez la fetuque elevee Festuca arundinacea Schreb. des differences varietales pour la valeur alimentaire avec des moutons a l'entretien, des chevres laitieres et des vaches laitieres. Ces differences etaient observees a l'auge. Nous avons voulu verifier si, et dans quelles conditions, elles se retrouvaient !ors d'une utilisation en paturage continu par des vaches laitieres. (cf Roden et al., 1987). Notre demarche peut aider a mettre en evidence les conditions de valorisation de la qualite dans les especes fourrageres.
Amelioration De La Qualite Du Fourrage Chez La Fetuque Elevee (Festuca Arundinacea Schreb.), W Pietraszek, J F. Chosson
Amelioration De La Qualite Du Fourrage Chez La Fetuque Elevee (Festuca Arundinacea Schreb.), W Pietraszek, J F. Chosson
IGC Proceedings (1977-2023)
Tres interessante dans nos climats pour son rendement et sa rusticite, la Fetuque elevee demande toutefois, pour etre davantage utilisee, qu'un effort de selection soit fait pour ameliorer sa qualite. Celle-ci est essentiellement determinee par l'appetibilite, l'ingestibilite et Ia digestibilite qui ne peuvent etre mesurees directement que par des troupeaux d'animaux. Leur mesure implique que !'on dispose d'une quantite importante de materiel vegetal et de plus le maintien et la manipulation des animaux sont lourds et couteux. Le selectionneur devrait done pouvoir disposer d'autres criteres, indirects, pour pouvoir estimer Ia qualite de son materiel vegetal dans Jes premiers stades du …
Productivity Of Selected High And Low Leaf Area Expansion Festuca Arundinacea Strains, D A. Sleper, C J. Nelson
Productivity Of Selected High And Low Leaf Area Expansion Festuca Arundinacea Strains, D A. Sleper, C J. Nelson
IGC Proceedings (1977-2023)
A selection program was initiated in 1975 to select for high (H) - and low (L)-LAER in a broad-based population of tall fescue ( Festuca arundinacea Schreb.) to improve vegetative herbage yield (Nelson and Sleper, 1983). Response to divergent selection was linear and symmetric for five cycles (Reeder et al., 1984). Mean increase in selecting for H-LAER was greater than 10 % per cycle ; a mean decrease of more than 8 % per cycle was observed when selecting for L-LAER. Nelson et al. (1977) and Reeder et al. (1984) showed that HLAER genotypes had wider leaves and higher leaf …

N-15 Study Of Nitrogen Uptake By Tall Fescue Throughout A Spring Growth, J Salette, Marie-Laure Decau, Francoise Vertes
IGC Proceedings (1977-2023)
In previous works, nitrogen uptake by a grass sward during regrowth has been studied and modelled (Salette and Lemaire, 1981 ; Lemaire and Salette, 1984). In this study, the use of N- 15 labelled fertilizer allows differentiation of two nitrogen sources for the plant nutrition : soil and fertilizer.
Assessment Of The Variation In Shear Strength Of Leaves Of Pasture Grasses, D A. Henry, R H. Macmillan, F M. Roberts, R J. Simpson
Assessment Of The Variation In Shear Strength Of Leaves Of Pasture Grasses, D A. Henry, R H. Macmillan, F M. Roberts, R J. Simpson
IGC Proceedings (1977-2023)
The shear strength of leaves of pasture grasses was measured using a shearing device. The mechanics of shearing were investigated and leaf strength was measured either as the force or the energy required to shear a leaf. The investigations indicate that the inherent strength of leaf tissue is best measured as a force corrected for the length of cutting blade in contact with the leaf. Inherent shear strength did not change along the length of a leaf blade, but did change with the physiological age of the leaf. Variation in shear strength within a population of annual ryegrass (Lolium …

Pasture Heterogeneity Created By Grazing Of Cattle Biotypes With Different Body Size, M S. Cid, M A. Brizuela, M S. Aello, C Ferri
IGC Proceedings (1977-2023)
Cattle grazing leads to the generation of patches differing in forage quality and quantity even in virtually monoespecific pastures. This work assesses the effect of two biotypes of different growth rate and mature body weight on the patchiness of a tall fescue pasture. We analysed height, herbage mass by unit surface, and proportions of heavily and lightly utilized patches through a residual herbage mass gradient generated by both biotypes at four stocking rates from March to December. At the end of spring the residual herbage of paddocks grazed by the small biotype was more heterogeneous. The percentage of heavily utilized …

Leaf Appearance Rate Of Native And Introduced Grasses Under Different Intensities Of Continuous Grazing (Argentina), M G. Agnusdei, A Mazzanti, J Cordero, M H. Wade
IGC Proceedings (1977-2023)
Results of two grazing experiments on the effect of maintaining contrasting sward states upon leaf appearance rate of individual tillers (LAR) and tiller density (D) are reported. The following species were evaluated: Cynodon dactylon(Cd), Leersia hexandra(Lh), y Paspalum dilatatum(Pd) in a natural grassland of the Flooding Pampa, and Festuca arundinacea in a sown pasture. Except for Pd, LAR decreased with the increment of sward surface height. The degree of this morphogenetic plasticity varied among species. Implications for the stability of grass populations under continuous grazing are suggested; the effect of sward state upon LAR may represent one alternative way …
Seed Yield Of Three Tall Fescue Cultivars As Affected By Endophyte Infection, T D. Phillips, M R. Siegel
Seed Yield Of Three Tall Fescue Cultivars As Affected By Endophyte Infection, T D. Phillips, M R. Siegel
IGC Proceedings (1977-2023)
Endophyte-infected (E+) tall fescue (Festuca arundinacea Schreb.) has enhanced fitness in some environments. The objectives were to measure the effects of the endophyte Acremonium coenophialum on seed yield traits and to determine the transmission rate of the endophyte from infected maternal plants into seed. Twenty infected and noninfected (E-) seedlings of each of three tall fescue cultivars were transplanted to the field in May, 1993. In 1994, there were significant differences between E+ and E- plants for panicle number and seed weight per panicle. In the second year, there were no differences between E+ and E- for the measured …

Establishment Vigor Of Endophyte Free And Endophyte Infected Tall Fescue Cultivars In Southern Ohio, C D. Penrose, H M. Bartholomew, R M. Sulc, E M. Volborn
IGC Proceedings (1977-2023)
Eleven cultivars of tall fescue (Festuca arundinacea, Schreb.) and two cultivars of orchardgrass (Dactylis glomerata L.) are part of a study to evaluate yield, establishment vigor, persistence and palatability under autumn stockpiling conditions. Included in the study are two endophyte infected-cultivars of tall fescue to compare interactions with endophyte free and infected cultivars. The results demonstrate that the newer endophyte-free and low-endophyte tall fescue cultivars evaluated are similar to other orchardgrass and endophyte-infected tall fescue cultivars in establishment vigor and early growth the year following establishment.

The Induction Of Dormancy In Grass Seed By Paclobutrazol: A Method To Improve Fall Seedings, P R. Salon, A A. Khan
IGC Proceedings (1977-2023)
Dormancy can be induced in grass seeds by soaking in aqueous solution of gibberellin synthesis inhibitors, such as paclobutrazol and tetcyclacis. In a study conducted with perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinaceae Schreb.), dormancy was induced by a 48 hour soak at 35° C in 100 micromolar tetcyclacis (TCY) and 100 micromolar paclobutrazol (PB) as determined by failure to emerge at 20° C. Emergence in the untreated, water soaked, TCY soaked and PB soaked seeds were 92, 92, 10 and 18 % respectively. The containers containing seed and seedlings were then held at 5°C …

Evaluation Of Grassland Advance Tall Fescue Under Grazing, R.J M. Hay, T B. Lyons, H S. Easton
IGC Proceedings (1977-2023)
Four cultivars of tall fescue (Festuca arundinacea Schreb.) were evaluated under sheep grazing at Palmerston North, New Zealand to assess the productivity and persistence of the newly released cultivar Grasslands Advance. Results from four years under grazing showed Grasslands Advance to be a considerable improvement over the older cultivar Grasslands Roa in both total sward yield and in dry matter contribution of tall fescue. It outperformed the other three cultivars in years 2 and 3 and was not significantly different to Grasslands Roa and AU Triumph in year 1 or AU Triumph in year 4. Seasonal production was excellent …
Perennial Cool-Season Grasses For The Warm Temperate Louisiana Coastal Plain, W D. Pitman
Perennial Cool-Season Grasses For The Warm Temperate Louisiana Coastal Plain, W D. Pitman
IGC Proceedings (1977-2023)
Despite a mild climate and relatively uniform distribution of rainfall, cool-season pastures in the Coastal Plain of the southeastern U.S. have been limited primarily to annual grasses and legumes. Preliminary evaluations indicated promise for the recently released cultivar, ‘Georgia-5’ tall fescue (Festuca arundinacea Schreb.), and an experimental Texas bluegrass (Poa arachnifera Torr.). Commercially available seed supplies allowed evaluation of the tall fescue at multiple sites, while the Texas bluegrass evaluation was limited by seed availability to a single small-plot experiment. Both site and management affected survival of the tall fescue sown into stands of warm-season grasses. Density of …
Forage Quality Of 'Matua' Bromegrass (Bromus Wildenowii), L G. Brown, J K. King
Forage Quality Of 'Matua' Bromegrass (Bromus Wildenowii), L G. Brown, J K. King
IGC Proceedings (1977-2023)
Research on forage quality of ‘Matua’ prairiegrass (Bromus wildenowii) is limited in Kentucky. Due to hot summers, mild winters and a 200-day long growing season in Kentucky, quality as well as management practices may differ from those reported in research from other climates. The objective of this study was to evaluate the forage quality of cool-season grasses including Matua, grazing bromegrass (Bromus stamineus), smooth bromegrass (Bromus inermis), tall fescue (Festuca arundinacea) and orchardgrass (Dactylis glomerata). The experiment was conducted in the field and greenhouse. Four harvests were obtained from each. Quality analyses …

Anatomy Of Forage Plant Parts In Relation To Digestion, P Rezvani Moghaddam, D Wilman
IGC Proceedings (1977-2023)
The objective of this study was to contribute some quantitative information regarding the proportion of cell types and the thickness of cell walls in different plant parts of three major forage species, lucerne (Medicago sativa L.), tall fescue (Festuca arundinacea Schreb.) and maize (Zea mays L.). All plant parts examined contained a significant proportion of cell types with walls which appeared too thick to be completely degraded during the time which plant particles are likely to spend in the rumen; this applied particularly to lucerne stems and maize leaf blades.

Storage Losses In Large Round Bale Using Various Storage Methods For Six And Eighteen Months, R C. Reeder, D H. Samples, H M. Bartholomew, S L. Boyles
IGC Proceedings (1977-2023)
Grass hay was baled with a variety of balers and tying materials in June, 1994 and 1995, at Jackson, Ohio. The bales were prepared and stored several ways. Waste hay accounted for less than ten percent of the dry matter after storage for six and eighteen months in all cases except one (a plastic wrap system intended for use with haylage). Bales stored inside had no waste. The best outdoor storage system, with less than one percent waste, used a ‘bale bonnet’ (top half covered with a plastic sheet) with the bale on a slatted pallet. One group of bales …

Influence Of The Acremonium Endophytes On Agronomic Traits Of Perennial Ryegrass And Tall Fescue In France, C Ravel, F Balfourier, G Charmet
IGC Proceedings (1977-2023)
Seven cultivars of perennial ryegrass (Lolium perenne) with (EI) and without (EF) Acremonium endophytes were compared in trial plots at 5 locations in France. Such a trial was also established with 6 tall fescue (Festuca arundinacea) cultivars in 5 locations. These trials were sown either in 1994 or 1995. Yields and visual traits (rust and drought tolerances, vigour 6-weeks following the sowing) were assessed. The data were analysed by means of variance analysis with two main factors (cultivars and endophyte status) and their interaction. As interaction was not significant, some significant differences between EI and EF …
