Evaluation Of Animal Productivity And Pasture Yield After Treatment Of Brigalow (Acacia Harpopylla) Regrowth With Tebuthiuron, G W. Fossett, P C. Venamore

IGC Proceedings (1977-2023)

Brigalow (Acacia harpophylla) regrowth was aerially treated with 2.0 kg/ha tebuthiuron (Graslan TM) at Blackwater, Australia in November 1989. Control of brigalow regrowth increased in grass production 2- fold, which resulted in dramatic animal live-weight gains. The live­weight advantage of steers grazing the tebuthiuron treated area was 31 kg/head compared with similar steers grazing the control paddock at similar stocking rates. After 20 months this advantage enabled 44% of stock to be marketed at premlum prices. A subset of steers implanted with a long-term hormonal growth promotant (HGP) (Compudose400™) and grazing the tebuthiuron-treated paddock recorded a 75 kg …

A Legume Ley System In Australia's Semi-Arid Tropics, R L. Mccown, K Thiagalingam, T Price, P S. Carberry, R K. Jones, N P. Dagliesh, D.C I. Peake

IGC Proceedings (1977-2023)

A large part of the Australian continent is semi-arid and tropical. While extensive beef cattle grazing is the most significant agricultural industry in this region, there Is some potential for dryland cropping. There are strong economic and- ecological reasons for exploring the possibility of a no-till tropical ley system. Work at Katherine, Northern Territory, found that a ley system based on Stylosanthes hamata cv. Verano showed considerable promise based on both contributions to dry-season animal performance and nitrogen contribution to succeeding coarse grain crops. Subsequent research and development in the wetter Douglas-Daly district of the Northern Territory has demonstrated even …

Implementation Of Organic Rice Farming Based On Local Wisdom In Bali Province, Indonesia, Gede Sedana, Ketut Wirawan, Naori Miyazawa

The Philippine Agricultural Scientist

The Green Revolution has significantly contributed to agricultural development. However, it has also caused environmental damage due to excessive use of agricultural inputs and land exploitation. To promote sustainability in line with the Sustainable Development Goals (SGDs), organic farming has been recommended to improve and maintain agroecosystems. In Bali Province, Indonesia, the concept of Tri Hita Karana (THK), a form of local wisdom, has guided farmers in implementing the System of Rice Intensification (SRI) technique introduced by the government. This study explored how organic rice farming integrates local wisdom, assessed farmers’ knowledge and attitudes towards SRI, and examined government support …

Applications Of Archaeal Antioxidant Coenzyme M As An Agricultural Biostimulant, Jeremy Hunter Brown

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

As the demand to meet global food security goals continue to increase, the need to increase efficiency and productivity of agricultural output also rises. This calls for innovative and cost-effective methods for improving plant growth and yield. Here we explore how antioxidants, molecules that inhibit oxidation and are necessary for redox based signaling and redox homeostasis, can be utilized as chemical biostimulants. Specifically, we investigated Coenzyme M, an antioxidant from archaea that holds potential economic advantages over other antioxidants. Chapter 1 provides a comprehensive review of antioxidants and how exogenously application of them affects plant growth and biology, highlighting the …

Evaluate A Personal-Sized Seedless Watermelon Grown In High Tunnels, Wenjing Guan

Midwest Vegetable Trial Reports

Growing personal-sized seedless watermelons in high tunnels is not a common practice in the U.S. However, as high tunnel adoption increases and farmers gain experience in using them for specialty crop production, there is a need to evaluate nontraditional crops to improve crop rotation within these structures. In this study, we evaluated the performance of a personal-sized seedless watermelon grown in a high tunnel system. This seedless watermelon cultivar was selected because of its thin rind, tender flesh, and high sugar content. The combination of these fruit traits may make it particularly attractive for local food markets. Additionally, we compared …

Changing Fire Regimes In The Great Basin Usa, Eva K. Strand, Kori Blankenship, Corey Gucker, Mark Brunson, Eugénie Montblanc

Aspen Bibliography

Wildfire is a natural disturbance in landscapes of the Western United States, but the effects and extents of fire are changing. Differences between historical and contemporary fire regimes can help identify reasons for observed changes in landscape composition. People living and working in the Great Basin, USA, are observing altered fire conditions, but spatial information about the degree and direction of change and departure from historical fire regimes is lacking. This study estimates how fire regimes have changed in the major Great Basin vegetation types over the past 60 years with comparisons to historical (pre-1900) fire regimes. We explore potential …

Abstract Urban areas are foci for the introduction of non-native plant species, and they often act as launching sites for invasions into the wider environment. Although interest in biological invasions in urban areas is growing rapidly, and the extent and complexity of problems associated with invasions in these systems have increased, data on the composition and numbers of non-native plants in urbanized areas remain scattered and idiosyncratic. We assembled data from multiple sources to create the Global Urban Biological Invasions Compendium (GUBIC) for vascular plants representing 553 urban centres from 61 countries across every continent except Antarctica. The GUBIC repository …

Flowers Of Black-Seeded And Yellow-Seeded Oilseed Pennycress (Thlaspi Arvense): Abundance, Timing, And Potential Insect Visitors, Frank Forcella, Riley Ellarson, Russ W. Gesch, Alex Hard, Nicholas J. Heller, Sarah Jandricic, M D. Marks, Yesuf Mohammed, William L. Perry, Winthrop B. Phippen, Lucas M. Roberts, Samantha Wells, Tad L. Wesley, Julia Zhang

The Great Lakes Entomologist

Pennycress is being developed in the Midwestern USA as a new oilseed crop that provides numerous ecosystem services. These services include being an early spring source of pollen and nectar for flower-visiting insects. Most past research on pennycress flower visitors used wild genotypes of pennycress. All wild genotypes have seed coats that are black, which occurs because of high levels of proanthocyanadins (PACs). Concentrations of PACs are minimal in newly developed genotypes with yellow-colored seed coats. However, little is known regarding flower abundance and timing nor insect visitation preferences for black-seeded genotypes (BSG) or yellow-seeded genotypes (YSG) of pennycress. Flower …

Occurrence Of Spotted Wing Drosophila (Drosophila Suzukii) In Wild Berries In Forested Areas Of Marquette And Keweenaw Counties, Upper Peninsula Of Michigan, Alexis M. Shatrau, Erika I. Hersch-Green

The Great Lakes Entomologist

Spotted-wing Drosophila (SWD, Drosophila suzukii Matsumura, Diptera: Drosophilidae) is an invasive fly that targets unripe soft-fruits causing premature ripening, dehiscence, and rotting. While the presence of SWD in agricultural systems is well-documented, much less is known about the host range of SWD in wild areas, especially in more northern latitudes where colder temperatures and short summers are thought to restrict their life-cycles and limit population growth. In 2019 and 2020, we collected wild berries from two counties in the Upper Peninsula of Michigan, with long, cold winters, to determine the prevalence, host range, and seasonal/temporal variation of SWD. We found …

Wild Licorice (Glycyrrhiza Lepidota) Identification And Management In Pastures, Jacob Hadfield, Taun Beddes, Michael Caron, Corey Ransom

All Current Publications

Wild licorice, also known as American licorice, is a perennial legume native to North America, commonly found in the western United States. Wild licorice reproduces rapidly through seeds and rhizomes, leading to large infestations, particularly in pastures. The low preference of livestock for wild licorice results in overgrazing of other plant species, leaving them at a competitive disadvantage, further promoting the spread of wild licorice and contributing to pasture infestations. This fact sheet reviews the identification and management of wild licorice in pastures.

Restore The Shore: A Guide To Lakeshore Revegetation In The Great Basin, Jes V. Braun, Rae Robinson, Annie L. Henry, Karin M. Kettenring

All Current Publications

Lakeshore vegetation supports many valuable aspects of lake ecosystems: foraging areas for birds, rearing grounds for fish, nutrient cycling, carbon storage, and aesthetic, cultural, and spiritual values. Yet, the vegetation of many lakeshores has been lost or heavily impacted by humans. What can be done to restore lakeshore vegetation to ensure that lakes remain healthy for future generations? In this guide, we summarize best practices for lakeshore revegetation (i.e., the process of actively reintroducing vegetation, usually native species, to a restoration site through seeding and planting) in the Great Basin.

Corn Tolerance To Florpyrauxifen-Benzyl Rates And Its Mixture With Atrazine And Mesotrione, Amar Godar, Jason K. Norsworthy, L. Tom Barber

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Florpyrauxifen-benzyl is a new synthetic auxin herbicide labeled in rice with a broad spectrum of control, typically more potent on broadleaf weeds. It has garnered some interest as a potential broadleaf weed control option for use in corn at low rates. Field experiments were conducted in Fayetteville, Arkansas, from 2019 through 2021 to examine the response of corn to postemergence applications of florpyrauxifen-benzyl at three rates (7.5, 15, and 30 g ae ha-1), as well as mixtures of the herbicide with atrazine (at half or full rate), mesotrione, or a combination of atrazine (at half rate) and mesotrione. Injury and …

Winter Hay-Feeding Effects On Soil Properties In A Rotationally Grazed Pasture System In The Ozark Highlands, Larry Berry, Kristofor R. Brye, Andrew Sharpley, Ron Morrow, Dirk Phillip, Tim A. Glover, James M. Burke, Mike B. Daniels

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Soil nutrient management for pastures in Arkansas often ignores nutrients applied from feeding hay to cattle. Discounting nutrient contributions from hay may increase the likelihood of unnecessary fertilizer over-application. This study evaluated the effects of unrolling bales (unroll fed, UF) and using a ring feeder (ring fed, RF), compared to an unamended control, on changes in soil properties in the top 4 inches in a rotationally grazed, beef [red angus (Bos taurus)] pasture on silt-loam soils in northwest Arkansas. Forty-six cow-calf pairs were fed hay at 6.6 tons acre(-1) year(-1) (14.8 Mg ha(-1) year(-1); dry-weight basis) from December to February …

Analysis Of 26 Studies Of The Impact Of Coconut Oil On Lipid Parameters: Beyond Total And Ldl Cholesterol, Mary T. Newport, Fabian M. Dayrit

Chemistry Faculty Publications

Coconut oil (CNO) is often characterized as an “artery-clogging fat” because it is a predominantly saturated fat that ostensibly raises total cholesterol (TChol) and LDL cholesterol (LDL-C). Whereas previous analyses assessed CNO based on the relative effects on lipid parameters against other fats and oils, this analysis focuses on the effects of CNO itself. Here, we review the literature on CNO and analyze 984 lipid profile data sets from 26 CNO studies conducted over the past 40 years. This analysis shows considerable heterogeneity among CNO studies regarding participant selection, the amount consumed, and the study duration. The analysis reveals that, …

Long-Term Agricultural Management Reduces Abundance And Alters Community Structure Of Ground Beetles (Coleoptera: Carabidae), Cynthia M. Fiser, Nathan L. Haan, Douglas A. Landis

Entomology Faculty Publications

Carabid beetles (Coleoptera: Carabidae) are beneficial predators and bioindicators of ground-dwelling arthropod diversity in agricultural landscapes. We studied changes in community composition, activity density, and diversity of carabids in a long-term agroecosystem study spanning 30 years in the US Midwest. We contrasted carabid community metrics measured by pitfall trap sampling in two conservation-oriented treatments in a corn-soybean-wheat rotation. One treatment uses conventional practices but with reduced agrochemical inputs (Reduced Input), while the other has no synthetic inputs (Biologically Based). Since a 1994–95 study on the same site, in 2019 overall carabid activity density had declined a minimum of 58–76 % …

Calliandra Calothyrsus - A Potential New Shrub Legume For Tropical Animal Production?, B Palmer, R A. Bray, T M. Ibrahim

IGC Proceedings (1977-2023)

Calliandra calothyrsus outyielded leucaena in cutting experiments at 2 sites in northern Australia and I in Indonesia. Drying significantly depressed the voluntary intake and digestibility of leaf, possibly due to the presence of tannin. Calliandra has the potential as a supplement for the low quality grass common to the tropics both ln grazing and cut-and-carry systems.

The last 20 years have seen major advances in research and development wilh tropical legumes. Research advances have been closely associated with substantial increases in the number and diversity of genetic resource collections, Release of a wide range of new cultivars has been based on selection for plant adaptation, persistence and productivity, screening for resistance to pest's and diseases, and the development of efficient seed production. Determination of fertiliser requirements and grazing management practices has resulted in sustainable animal production from legume-based pasture systems. Extensive pasture development has now occurred in both high and low input systems. Options vary from …

Integration Of Wildlife And Cattle On Communal Lands In Kangwane, South Africa, M Stalmans, A Van Wyk, M T. Mentis

IGC Proceedings (1977-2023)

The feasibility of integrating wildlife with the current livestock husbandry on communal lands in KaNgwane was investigated. Present stocking rates were 3 times the recommended figure for production farming. This fitted predictions based on the Jones-Sandland model for populations where the major consideration is maximum number of animals rather than high productivity. The integration of game was seen as a means to increase economic output, while spreading benefits from the use of natural resources to the community at large and establishing a form of ecologically sustainable land use. The active involvement of the community in the planning process and their …

Game Production On Private Land In South Africa, J C. Pauw, M J.S Peel

IGC Proceedings (1977-2023)

The game industry on private land in South Africa has grown considerably in the last 30 years, resulting in a greatly increased biodiversity on private rangeland. However, animals are not domesticated and management is difficult. Management becomes even more complex because commercial game production normally involves a number of species, including domestic stock, in the same production system. Mixed livestock-game ranching holds certain advantages for management and is generally perceived to be more profitable than either alone. Because of human preferences, a lack of clearly defined management objectives and lack of practical management recommendations, veld is generally heavily utilised and …

Overcoming Limitations On The Productivity Of Browsing Ungulates In Africa, Norman Owen-Smith

IGC Proceedings (1977-2023)

In African savannas primary production by woody plants may match that by the grass layer. However, maximum population levels attained by browsing ruminants are only one tenth of those reached by similar sized grazers, The productivity of browsers is limited because (I) much foliage is out of reach, and dispersed by wind when shed; (2) most palatable trees are deciduous, leading to a food bottleneck during the late dry season; (3) leaves of many woody species are rendered unpalatable, indigestible or toxic by plant secondary metabolites. Management actions to overcome these limitations include (I) lopping trees to restrict their height; …

In Africa, traditional use of wildlife involves open access systems on public land, Here, free ranging, public wildlife resources are used to produce subsistence or marketed meat and skins at smaII scale. Traditional livestock systems involve open access use of rangelands. Here, livestock are kept at small ·scale to produce draft power, milk, meat and as a store of .value. Commercial use of wildlife involves restricted access systems on both public and private lands. Here, …

Conservation Of Biodiveristy In Managed Rangelands, With Special Emphasis On The Ecological Effects Of Large Grazing Ungulates, Domestic And Wild, Patrick Duncan, Peter J. Jarman

IGC Proceedings (1977-2023)

Biodiversily with its different components (genes, species and ecosystems) is defined in relation to rangelands, whose Importance in its conservation is described. At the fine scale grasslands are much more diverse than tropical rain forest, and are comparably diverse at a regional scale, at least in Africa. Rangelands are crucially important world wide for 1he conservation of plants, and also for birds and large mammalian herbivores. Large ungulates (and other large herbivores) ace "keystone" species in these·ecosystems, playing a crucial role in the maintenance of diverse communities of plants, birds and invertebrates associated with such grasslands.

Productivity Of Silvipastoral Areas And Management Needs In Arid Regions Of India, N C. Jain

IGC Proceedings (1977-2023)

In an extremely arid state of India (Rajasthan) having high livestock concentration and vast degraded lands, the State Forest Department has developed community and forest lands into silvipastoral areas by sowing grass (mainly Cenchus ciliaris and C. setigerus) in association with trees. Surveys have revealed high variability in pasture establishment and productivity in different regions. Cenchrus established well in most regions, except the extreme south, if proper sowing methods with closer spacing were followed and soil conservation measures undertaken. Closure from animals helped in favourable grass succession. Establishment of Dichanthium annulatum and Stylosanthes hamata was relatively poor, Analysis of …
