#Goingtothefair: A Social Media Listening Analysis Of Agricultural Fairs, Julie A. Mahoney, Nicole Olynk Widmar, Courtney Bir

Department of Agricultural Economics Faculty Publications

Agricultural fairs provide one of the last frontiers, and largest stages, for showcasing livestock agriculture to the public. However, public funding, attendance revenue, animal biosecurity, and public health concerns are all aspects worthy of conversation and increased research attention given the interaction between livestock animals and the general public in fair and festival settings. A prominent social media listening and data analytics platform was used to quantify online and social media chatter concerning agricultural fairs during a 27-mo period. A general search for online media referencing agricultural fair keywords was designed; social and online media mentions of agricultural fairs ( …

The Value Of Soil Sampling And Sampling Density: Conceptual Framework (Part 1), Taro Mieno, David Bullock

Cornhusker Economics

When considering variable-rate nitrogen or seed application, soil sampling can provide farmers and their consultants with valuable information about the spatial distributions of soil properties such as organic matter, micro- and macro-nutrients, and pH. Conceptually, that information may be especially valuable for site-specific input management. But just as farmers make decisions about input applications, they also must make decisions about soil sampling, and in particular, must choose soil sampling density. It is standard practice for U.S. corn and soybean farmers to take soil samples on their fields every three or four years at a density of one sample per 2.5 …

Evaluating Opportunities For Integrated Crop Livestock Systems In Eastern Nebraska, Elizabeth Kay Christenson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Current agricultural systems focused on production of few commodities are facing production, economic, and environmental challenges. To address these challenges, Integrated Crop Livestock Systems (ICLS) have emerged through three primary methods 1) perennial grasslands for grazing and/or hay production, 2) crop residue grazing, and 3) cover crop grazing. To evaluate potential of ICLS mitigating current challenges, a field scale model ICLS was developed in 2015. The ICLS includes 4-ha each of ‘Newell’ smooth bromegrass (Bromus inermis L.), ‘Liberty’ switchgrass (Panicum virgatum L.), and ‘Shawnee’ switchgrass. The ICLS also included 8-ha of continuous corn (Zea mays L.). In …

Performance Evaluation Of Four Arkansas Table Grape Cultivars Grown On Three Trellis Systems Under High Tunnels At Two Locations In Arkansas., Jose Hernandez

Graduate Theses and Dissertations

Grapevines (Vitis vinifera L.) are one of the most important horticultural crops world-wide. In the southern U.S. region, hot and humid climate accompanied by high pest pressure requires high levels of labor and pesticide inputs, making open field table grape production unsustainable. Previous research at University of Arkansas has demonstrated that table grape production under high tunnels (HTs) is a viable option to overcome biotic and abiotic challenges in the region. This project evaluated two HTs established in Arkansas. In the spring of 2014, at Fayetteville, three table grape cultivars (Faith, Gratitude, and Jupiter) were established in an 8 x …

Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Craig Krogstad

Department of Animal Science: Dissertations, Theses, and Student Research

Improving the digestibility of fiber and our understanding of how to feed it will optimize the ruminants’ niche in our society, which is to convert human inedible products to high quality protein in the form of meat and milk. Neutral detergent fiber (NDF) digestibility has been studied and modeled for decades, but it is increasingly important as livestock production is scrutinized for resource use and sustainability. Increasing the amount of NDF fed and improving models of NDF digestibility will improve sustainability by increasing the precision at which we feed livestock which results in less nutrient and greenhouse gas (GHG) emissions. …

The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1^st study assessed growth deficits in IUGR juvenile lambs and the benefits of treatment with adrenergic and inflammatory mediators. Growth metrics including bodyweight, rate of gain, and crown-rump length were diminished by placental insufficiency-induced IUGR through 2 mo. of age but were recovered by daily clenbuterol or curcumin supplementation. Body composition metrics indicated by bioelectrical impedance, proximate analysis, and loin size revealed that fat-free lean mass, specific muscle group sizes, and protein-to-fat ratios were reduced in unsupplemented IUGR lambs but recovered to or even past controls in clenbuterol-supplemented lambs. From these findings, we conclude that IUGR impairs postnatal …

Soybean Maturity Group And Planting Date Influence Grain Yield And Nitrogen Dynamics, Carrie C. Ortel, Trenton L. Roberts, Kyle A. Hoegenauer, Larry C. Purcell, Nathan A. Slaton, Edward E. Gbur

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Manipulation of soybean [Glycine max (L.) Merr.] maturity group (MG) and planting date will increase the yield of a soybean crop while simultaneously influencing the potential soil-nitrogen (N) credits. Variations in N returned to the soil by soybean can significantly affect the amount of fertilizer-N needed for the subsequent crop. Four soybean MGs (3.5, 4.7, 5.4, and 5.6) were evaluated at optimal and late planting dates in Arkansas. Grain yield was significantly different among MGs in 2016 (P = .0012) and 2017 (P = .0004), with the 4.7 MG consistently yielding the highest at 3,232 kg ha(-1). Plant total aboveground …

Soil Labile Organic Carbon Fractions And Soil Enzyme Activities After 10 Years Of Continuous Fertilization And Wheat Residue Incorporation, Ligan Zhang, Xi Chen, Yujun Xu, Mengcan Jin, Xinxin Ye, Hongjian Gao, Wenying Chu, Jingdong Mao, Michael L. Thompson

Chemistry & Biochemistry Faculty Publications

Labile organic carbon (LOC) fractions and related enzyme activities in soils are considered to be early and sensitive indicators of soil quality changes. We investigated the influences of fertilization and residue incorporation on LOC fractions, enzyme activities, and the carbon pool management index (CPMI) in a 10-year field experiment. The experiment was composed of three treatments: (1) no fertilization (control), (2) chemical fertilizer application alone (F), and (3) chemical fertilizer application combined with incorporation of wheat straw residues (F + R). Generally, the F + R treatment led to the highest concentrations of the LOC fractions. Compared to the control …

Bedstraw Eradication Program 2019/2020 - Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Three-horned bedstraw (Galium tricornutum) is a competitive weed that can cause considerable yield loss in crops, and its seeds are contaminants of fodder and grain. The presence of bedstraw requires infested areas to be quarantined whilst a nine-year program is undertaken – six years of herbicide treatments followed by a three-year ‘release phase’.

In 2019/20 the Program reached a major milestone with quarantine restrictions fully lifted from one property and lifted from the arable areas of a second property. This is a major step toward eradicating bedstraw from Western Australia.

Skeleton Weed Program 2019/2020: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

2019/20 saw the Skeleton Weed Program expand its surveillance and control activities, with financial support from the IFS, specifically:

- Landholder incentives for paddock surveillance were increased and made available for surveillance undertaken on reinfested ‘Code 2’ paddocks. These changes were anticipated to enhance the level of surveillance for skeleton weed, enabling plants to be identified and treated and, therefore, reducing the risk of seed-set and spread.

- The IFS covered the cost of chemical for winter spraying undertaken on heavily infested paddocks. It was anticipated that this would help landholders reduce the level of skeleton weed infestation and, in …

Selection Of The Most Appropriate Tillage System Based On Topsis Model With Emphasize On Impact Of Different Tillage Systems On Yield, Ali Mirzazadeh, Razieh Pourdarbani, Salman Fekri

Emirates Journal for Engineering Research

Among the various agricultural operations, tillage alone accounts for 60% of the energy consumed in agriculture. Other concerns, such as soil compaction, time management, economic issues, porosity reduction, moisture storage capacity, as well as a 25% increase in water and wind erosion, has further fueled efforts to improve tillage methods. In this regard, conservation tillage is more considered by experts. This study was conducted to evaluate important indices of wheat production in different tillage methods. Two plots located in Moghan Agro Co. were selected and were divided into four equal 2.8 hectares. Experiments were performed in randomized complete block design …
