Evaluating Substrate Stratification Practices For Enhanced Water Resource Management In Nursery Production, Kristopher S. Criscione

LSU Master's Theses

The nursery and greenhouse industries have continued to increase in production and sales over the past two decades. This increase in horticultural production necessitates a greater demand for finite natural resources, specifically water. Sustainable water resource management will be critical to the success and continual growth of the nursery industry. Strategic irrigation scheduling and innovative substrate management practices can improve nursery resource efficiency. Soilless substrates were originally utilized by the industry to increase substrate air-filled porosity, to ensure adequately drained container systems. Thus, the implementation of these soilless substrates can lead to an inefficient use of water and fertilizer. Substrate …

The Ethically Conscious Flower Consumer: Understanding Fair Trade Cut Flower Purchase Behavior In Germany, Meike Rombach, David L. Dean, Nicole Olynk Widmar, Vera Bitsch

Department of Agricultural Economics Faculty Publications

Fair trade flowers are an important niche product relevant to ethically conscious consumers. The study proposes a model that investigates key factors affecting the behavior of these cut flower consumers in Germany. The study serves to complement the existing studies dedicated to preferences for flower attributes and products, as well as consumers’ willingness to pay. It builds on an online survey with a representative sample of 772 German cut-flower consumers. Partial least squares structural equation modelling shows that concern for the treatment of workers from countries with poor environmental and labor reputations, the breadth of fair trade cut flower information …

Challenges Of Making Financial Decisions And Avoiding Fraudulent Schemes, Fabio Mattos

Cornhusker Economics

Last month there was an article in the local newspaper about a man accused of defrauding commodity investors for several years in Nebraska. This person is a commodity pool operator (CPO), who is an individual or organization that operates a commodity pool and solicits funds for that pool. A commodity pool is an enterprise in which funds contributed by a number of clients are combined for the purpose of trading futures contracts, options contracts, among other types of financial products. Generally speaking, a CPO manages an investment fund focused on commodity products.

Casting A Critical Lens On Global Development: A Multimethod Investigation Of The Masculine Hegemonic Forces That Marginalize Women In Agriculture, Morgan Alyse Richardson Gilley

LSU Doctoral Dissertations

A critical link between gender equality and agricultural development has been established in the literature. However, disparities between genders have persisted in many areas of the developing world. One strategy that has been used to reduce gender inequalities has been educational outreach opportunities through agricultural extension, which has provided women a critical pathway to empowerment. Despite this, a lack of knowledge on the experiences of women in agriculture throughout Southeast Asia has served as a barrier to the advancement of such work. This investigation sought to better understand the issues facing this region’s fight to attain gender equality. To achieve …

Evaluation Of Cold-Hardy Grapes On The Wasatch Front, Michael Caron, Taun Beddes, Michael Pace, Brent Black

All Current Publications

Grapes can be an excellent addition to home gardens and a revenue opportunity for small-acreage farms. Utah’s Wasatch Front region, along with portions of Cache Valley, are well suited to grow grapes, particularly the more cold-hardy cultivars. Many new cold-hardy cultivars have been introduced over the last few decades, including both wine and table types. However, many of these newer cultivars have not been adequately tested in Utah’s unique climate. Utah State University Extension conducted a grape cultivar comparison planting in Lehi, Utah. This fact sheet reviews the outcomes of the study and offers information on tested varieties that have …

Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer

The Great Lakes Entomologist

Naturally occurring predator and parasitoid communities are well known to respond to multiple scales of environmental heterogeneity within and around agroecoystems, yet our understanding of which scales are most influential on different functional guilds of enemies is limited. Using vote-counting methodology, we synthesized the results from 40 empirical studies that observed how natural enemy richness, diversity, or parasitism rate is affected by environmental heterogeneity at a local scale (e.g. a focal field), an intermediate scale (e.g. habitat in immediate proximity of a focal field), and landscape scale (e.g. habitat within >200 m radius around focal field). Heterogeneity at all scales …

Embryo Lethality Assay As A Tool For Assessing Virulence Of Isolates From Bacterial Chondronecrosis With Osteomyelitis In Broilers, Nnamdi S. Ekesi, Amer Hasan, Alia Parveen, Abdulkarim Shwani, Douglas D. Rhoads

Cell and Molecular Biology Faculty Publications and Presentations

We used an embryo lethality assay (ELA) to assess virulence for different isolates from cases of bacterial chondronecrosis with osteomyelitis (BCO) in broilers. Lameness is among the most significant animal welfare issues in the poultry industry. Bac-terial infections are a major cause of lameness and different bacterial species have been obtained from lame broilers. Reliable lab-based assays are required to assess relative virulence of bacteria obtained from lame broilers. ELA has been used to assess lethal dosage of Enterococcus faecalis and Enterococcus cecorum. We hypothesized that ELA could substitute for more laborious and costly assessments …

Growing Faba Beans On The South Coast Of Western Australia, Sarah Belli, Carla Milazzo, Emma Pearse, King Yin Lui, Grace Williams, Jeremy Lemon

Grain and other field crops published reports

Editors: Megan Abrahams, Andrew Blake and Vanessa Stewart (DPIRD)

Foreword

Thirty-three years ago I started work in Esperance on broadleaf crops. One of the best things my boss set up for me was arranging visits with several lupin farmers so I could follow their crops from seeding, through the growing season, to harvest. It was a great way to quickly get an idea of the choices farmers make and the reasons why.

With today’s busy lives, most farmers would be hard pressed to have the luxury of visiting many other farmers multiple times to learn how to grow a crop. …

2021 Cantaloupe Variety Evaluation In Indiana, Wenjing Guan, Dan Egel, Dennis Nowaskie, Dean Haseman

Midwest Vegetable Trial Reports

Indiana ranks sixth in cantaloupe production in the US. A total of 1,800 acres of cantaloupes were planted in Indiana with a production value of $8.6 million in 2018 (USDA 2021). Melon produced in Indiana is primarily eastern-type cantaloupes. Traditional eastern-type cantaloupes have less pronounced netting, larger fruit size, softer flesh and shorter shelf life compared with western-type cantaloupes. They are harvested at quarter-slip to full-slip stage, and require frequent harvest. Recently, extended shelf life varieties have been developed and are becoming attractive in the eastern market. This variety trial included 11 traditional eastern-type cantaloupes, as well as extended shelf-life …

Research Note: Evaluation Of Quinine As A Chemoprophylactic Candidate Against Histomoniasis In Turkeys, L. C. Beer, B. M. Hargis, C. N. Vuong

Poultry Science Faculty Publications and Presentations

Histomoniasis, also commonly referred to as blackhead disease, is caused by the protozoan parasite Histomonas meleagridis. Since the removal of nitarsone in 2015, no approved prophylactics are available for mitigating histomoniasis. Disease incidence and high mortalities are frequently associated with turkey flocks, although infection of broiler breeders also occurs. Quinine is a naturally occurring alkaloid with antimalarial properties. In vitro assays have shown strong antihistomonal properties of quinine, leading to our hypothesis that quinine inclusion within the feed could prevent histomoniasis in turkeys. Selected concentrations of quinine were included within a turkey starter diet to evaluate effects on body …

Department of Agronomy and Horticulture: Faculty Publications

Strawberries are only seasonally available in Nebraska (NE). If an affordable heated structure can be designed, then opportunity exists to increase on-farm income by producing strawberries off-season during high-value market periods. A series of university greenhouse trials were conducted from 2010 to 2012. The varieties Evie-2 and Seascape were identified as being most productive under a low technology growing scheme. A new research project, which ran from fall to late spring (2013–2014), was designed to determine if this production scheme would translate to a commercial grower. Varieties Seascape and Evie-2 (each at two grades indicated by +) and San Andreas …
