Trifolium Pratense - Environmental Weed Risk Assessment 2022, Department Of Primary Industries And Regional Development, Western Australia

Environmental Weed Risk Assessments

Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Red clover (Trifolium pratense). Red clover is a temperate, perennial (and sometimes biennial) pasture legume, which is native to Europe and Northern Asia. It is now cultivated for forage in temperate areas worldwide but is sensitive to high temperatures so has a limited role in Australia. It was evaluated in early pasture trials in high …

Vaccinium Corymbosum - Environmental Weed Risk Assessment 2022, Department Of Primary Industries And Regional Development, Western Australia

Environmental Weed Risk Assessments

Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Blueberry (Vaccinium corymbosum). The blueberry (Vaccinium spp.) is an evergreen perennial shrub, growing up to 3m tall. The fruit is a many-seeded blueberry, with white or pale green flesh. Varieties grown in Australia are classified into Southern Highbush, Rabbiteye and Northern Highbush which require varying levels of chilling (i.e. hours below 7°C to induce flowering).

Comparative Performance Of Cooperative Equity Retirement Plans, Jeffrey S. Royer

Department of Agricultural Economics: Faculty Publications

This paper compares the performance of revolving fund, percentage-of-all-equities, and base capital plans, and special plans for redeeming equity held by estates or based on member age. It also examines how the performance of the base capital plan is affected by changes in the base period, relaxing the equity requirements for underinvested members, and a variable cash patronage refund program. The base capital plan performs better than other systematic plans but places financial burdens on young members. Two modifications can mitigate that problem with only a slight diminution in performance. Special plans benefit cooperatives operating revolving fund plans the most.

Anaerobic Digestion Of Cereal Rye Cover Crop, Liangcheng Yang, Lucas D. Lamont, John C. Sedbrook, Nicholas J. Heller, David E. Kopsell

Faculty Publications - Agriculture

The rapid growth of cover crop planting area in the U.S. helps with erosion control, soil health, control of greenhouse gases, and also provides abundant biomass for the production of bioenergy and bioproducts. Given the cover crops’ compositional heterogeneity and variability, a tolerate platform technology such as anaerobic digestion (AD) is preferred but has not been widely used for cover crop biorefining. This study evaluated the biogas and methane yields from six cereal rye (Secale cereale L.) cover crops grown in the Midwest, using both bench- and pilot-scale anaerobic digesters. The effects of two critical factors, the total solids (TS) …

Selected Dietary Plant-Based Proteins For Growth And Health Response Of Nile Tilapia Oreochromis Niloticus, Tzodoq O. Magbanua, Janice A. Ragaza

Biology Faculty Publications

Tilapia culture is one of the largest sectors of global aquaculture. Among the different species of tilapia, Nile tilapia (Oreochromis niloticus) is perhaps the top cultured species. The production of Nile tilapia has been continually increasing throughout the years resulting in genetic deterioration. Several tilapia strains with better growth performance and adaptive capability to survive in different culture conditions have been developed to alleviate the crisis. Increased demand for Nile tilapia implies higher farming cost. Plant-based proteins are utilized as partial or complete fishmeal replacements to reduce feed cost. However, these proteins can adversely affect and alter growth …

Mathematics & Statistics Faculty Publications

Background

Several studies conducted in Europe have suggested a protective association between early-life farming exposure and childhood eczema or atopic dermatitis; however, few studies have examined associations in adults.

Objectives

We investigated associations between early-life exposures and eczema among 3217 adult farmers and farm spouses (mean age, 62.8 years) in a case–control study nested within an US agricultural cohort.

Methods

We used sampling-weighted logistic regression to estimate odds ratios and 95% confidence intervals for associations between early-life exposures and self-reported doctor-diagnosed eczema (273 cases) and polytomous logistic regression to estimate odds ratios (95% confidence intervals) for a 4-level outcome combining …

An Improved Understanding Of Diplodia Ear Rot In Kentucky Corn, Nolan Ryan Anderson

Theses and Dissertations--Plant Pathology

Stenocarpella maydis and Stenocarpella macrospora are both causal agents of Diplodia ear rot (DER) of corn in the U.S. The current prevalence and distribution of each is unknown worldwide. Signs and symptoms of DER include white mold on and between kernels, bleached husks, and pycnidia visible in the cob pith. The term hidden Diplodia describes when no mycelia or bleached husk is present, but pycnidia are still visible inside the cob. This phenomenon is reported to be caused by late infections of Stenocarpella spp. New fungicide nozzle technology has been promoted to increase spray coverage in the lower canopy, which …

Use Of Heterothallic Mat Deletion Strains Of Fusarium Graminearum As Test Mates In Crosses To Evaluate The Genetics Of Pathogenicity And Fitness, Gabdiel Emmanuel Yulfo-Soto

Theses and Dissertations--Plant Pathology

Fusarium Head Blight (FHB), caused by Fusarium graminearum sensu stricto and other members of the F. graminearum species complex (FGSC), is a plant disease that occurs on cereal crops worldwide. FHB causes yield losses not only by reducing grain weight, but also by contaminating the kernels with dangerous trichothecene mycotoxins, especially deoxynivalenol (DON). There is a high degree of genotypic and phenotypic variation among pathogen species and strains, but current FHB risk assessment models and treatments do not account for pathogen diversity. Therefore, it is difficult to predict what will happen if a new, potentially more aggressive variant is introduced, …

Preventative Weed Management Strategies In Arkansas Tomato Production, Gracie E. Morrison, Matthew Bertucci

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent herbicide application (plots sprayed with herbicide prior to weed emergence), straw mulch (plots bedded with straw), landscape fabric (plots covered in fabric), and untreated weedy control plots. These six treatments were applied to randomized blocks in a high tunnel. Weeding, planting, and harvesting were all …

Predicting Munsell Color For Turfgrass Leaves, William L. Berndt, Roch E. Gaussoin

Department of Agronomy and Horticulture: Faculty Publications

Linking turfgrass color to hue, value, chroma (H V/C) in the Munsell Plant Tissue Color Book is a visual comparison process for specifying and communicating plant color. If subjectivity of visual comparison can be mitigated, then accuracy of color matching may be improved. Research was conducted to develop an algorithm predicting H V/C from CIE-xyY color (xyY) in digital images of leaves of four turfgrasses. First, value-chroma (V/C) arrays for Munsell hue groups 5Y, 2.5GY, 5GY, 7.5GY, 10GY, and 2.5G were converted to xyY. Next, chromaticity (xy) plots from each array were fitted with …

Regenerating Agroecosystems By Overcoming Human Exceptionalism In Designing For Increased Equity Of Benefits From Ecoservices, Ali Loker, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Our commentary explores three critical issues related to ecosystem services. First is how ecoservices are currently designed and implemented primarily for human benefit without concern for how these impact other species. We conclude that awareness of this imbalance is the first step toward meaningful change. Second we observe that human exceptionalism guides most decisions, and ask whether we can overcome this mind-set to embrace ecoregeneration and design of resilient and mutually beneficial agroecosystems. Our attitude toward the challenge and moving toward greater humility about human roles that guide management decisions in the ecosystem is a requisite for change. Third we …

Management Of The Brown Marmorated Stink Bug (Halyomorpha Halys) (Hemiptera:Pentatomidae) On Small Acreage And Organic Vegetable Systems, Lauren Fann

Theses and Dissertations--Entomology

Invasive species can be very disruptive to established integrated pest management programs. They can cause increases in broad-spectrum insecticide applications with variable effectiveness to mitigate damage. However, not all introduced species develop invasive characteristics; often, many introduced species go undetected. It is not until a species begins to cause economic damage to commodities essential to humans that it becomes classified as an invasive pest. Many challenges arise with the management of invasive pests due to lack of understanding of their biology, behavior, and absence of natural enemies in their introduced range. This often results in poor management and population outbreaks …

Optimising The Carcass Merit Of Irish Beef Cattle Using Genetic And Non-Genetic Information At The Animal And Herd Level, David Kenny

Theses

Failure of beef carcasses to achieve desirable carcass specifications represent inefficiencies within the supply chain, namely greater carcass processing costs and the inability of the resulting primal cuts to conform to high-value market specifications. Analysis of a representative sample of prime Irish beef cattle conducted in this thesis determined that 59% of cattle fail to achieve the desired carcass specifications of the supply chain at slaughter. The objective of this thesis was to use readily available information to define strategies that could help to reduce this statistic. Firstly, the likelihood of Irish beef carcasses achieving the desired carcass specifications was …

Where's The Beef? Meat Shortages, Farmer Needs, And Long-Term Recovery Policies In A Pandemic Era, Kim Vu-Dinh

Faculty Scholarship

COVID-19 not only affected every hospital bed in the nation--if not the world; it also affected nearly every dinner table in America and beyond. Supply chain disruptions caused by the pandemic highlighted deep-seated problems with how we get our meat, and how difficult we make it for American farmers to sell to the family next door. Within a few months of the first reported case in the US, hundreds of workers from just two meat-processing plants on American shores became infected with COVID-19, and imports from around the world came to a standstill as factories and shipping companies were forced …
