Three Essays On The U.S. Beef Supply Chain: Production, Marketing, And Price Dynamics, Erdal Erol

Theses and Dissertations--Agricultural Economics

This dissertation contains three essays on select economic components of the U.S. beef industry. The first and second essays concentrate on the different economic problems in beef cattle production. The third essay evaluates the price dynamics and the impact of COVID-19 along the beef supply chain.

The first essay explores the economics of culling decisions in cow-calf operations in the U.S. with a novel application of a dynamic mathematical programming model. The results provide an optimal culling strategy under the base model and a range of optimal strategies that vary with respect to different components such as fertility probabilities, market …

Community Supported Agriculture Values: A Comparison Across Groups, Thomas B. Pierce

Theses and Dissertations--Agricultural Economics

Community Supported Agriculture (CSA) programs offer consumers the chance to share the risk with farming operations while gaining access to fresh, local foods. While research on CSA shareholder values such as share affordability or the local impact of participation has been conducted in the past decade and beyond, less attention has been paid to direct value-mapping of the shareholders themselves. This research seeks to determine consumer values around the CSA purchasing decision using the Best-Worst Scaling Approach. Based on a focus group discussion with CSA shareholders in a university wellness voucher program, we used affinity diagramming to develop a list …

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Introduction: The combined populations of China and India were 2.78 billion in 2020, representing 36% of the world population (7.75 billion). Wheat is the second most important staple grain in both China and India. In 2019, the aggregate wheat consumption in China was 96.4 million ton and in India it was 82.5 million ton, together it was more than 35% of the world's wheat that year. In China, in 2050, the projected population will be 1294–1515 million, and in India, it is projected to be 14.89–1793 million, under the low and high-fertility rate assumptions. A question arises as to, what …

The Molecular Regulators, Pathways, And Environmental Impacts Of White Flowers, Sagheer Ahmad, Zaibun Nisa, Muhammad Zeeshan Munir, Muhammad Imran, Shaista Nosheen, Kai Zhao

Turkish Journal of Agriculture and Forestry

White flowers are an important element of natural beauty, although they are thought of colorless. Anthocyanins are the major compounds responsible for a variety of pigments in flowers. White flowers surely lack pigmented anthocyanins and other compounds, but there are regulatory mechanisms that hinder the deposition of color pigments in white flowers. Moreover, there are also some compounds that deposit to instigate white appearance and the genetic regulators control the biosynthesis and deposition of such compounds. Experts have shown that fluctuation in the equilibrium of FLS and DFR genes determines the degree of accumulation of anthocyanins and flavonols in the …

A Concise Study On Essential Parameters For The Sustainability Of Lagoon Waters In Terms Of Scientific Literature, Shuraik Kader, Morufu Olalekan Raimi, Velibor Spalevic, Austin-Asomeji Iyingiala, Raheem Waliyat Bukola, Lizny Jaufer, Talib E. Butt

Turkish Journal of Agriculture and Forestry

Agriculture encompasses both plant growing (agronomy, horticulture, and forestry) and animal husbandry. Aquaculture is the aquatic embodiment of agriculture. Lagoons are the main sources of aquaculture in various countries around the world which especially yield shrimp, finfish, macrophytes, and mollusk. Agricultural effluents are highly affecting the lagoon water quality parameters in Sri Lanka since most of the agricultural farmlands in the country are on coastal landmasses. It leads to the increased risks of lagoon water contamination. Therefore, it is essential to identify the water quality parameters affected by anthropogenic agricultural activities and establish their threshold limits for ensuring the sustainability …

Genetic Diversity, Heritability, Correlation Coefficient, And Path Analysis Of Forage Yield Components In Iranian Phalaris Aquatica L. Genotypes, Reza Mohammadi, Alireza Pourmohammad, Mohammad Bagher Hassanpouraghdam, Serap Di̇ler

Turkish Journal of Agriculture and Forestry

Twenty-six selected genotypes of Phalaris aquatica L. from Iranian germplasm were evaluated to evaluate the genetic diversity of some agromorphological characteristics. Each selected genotype was cloned and planted as spaced single plants according to a randomized complete block design (RCBD) with four replications in 2016 and 2017. Large and significant (p < 0.01) differences among genotypes were found for all traits. The estimates of broad sense heritability were low to high (h$^{2}$$_{b}$ = 0.16 - 0.75) for studied traits. High heritability estimates for dry matter yield (DMY) indicate a sufficient genetic variability for further improvement. There was the highest heritability rate and genetic advance for plant height and DMY. Selection for traits with high heritability and genetic advance can be successful. The dry matter yield cut 1 (DMY1) correlation with the number of days to flowering, number of days to pollination, plant height, and crown diameter cut 2 was positive and significant. In stepwise multiple linear regression, the plant height, number of stems per plant, and spike length explained more than 84% of the total variation of DMY1. The plant height was the most crucial component of DMY1. The path analysis showed that plant height positively affected DMY1 (0.83). The highest negative indirect effects on DMY1 were observed for plant height via the number of stems per plant (-0.238). Axes 1 and 2 of the principal coordinate analysis explained 40.94% and 18.48% of the variation, respectively, and, although not entirely separated, general groupings can be determined. In factor analysis, component 1 was positively associated with the traits dry matter yield cut 2 (DMY2) (0.855), dry matter yield (0.821), and plant height (0.755). Therefore, the first component can be called the biomass component. Finally, selection would be more effective in improving forage yield based on yield components. In conclusion, the results indicated appropriate genetic variability in the studied genotypes. However, the studied genotypes will deliver a valuable germplasm to employ in breeding programs for forage cultivar production. This progress is crucial in introducing these selected genotypes to develop a core collection of Phalaris aquatica germplasm in Iran.

Turkish Journal of Agriculture and Forestry

Many studies indicate the favorable effect of biochar on soil quality and plant fitness. A few studies on the biochar interactions with rhizosphere bacteria and their impact on plant development and nutrient acquisition have been reported. In this study, pot experiments in a glasshouse were performed to figure out the interactive effect of plant beneficial bacteria Pseudomonas putida TSAU6 and biochar amendment on the wheat (Triticum aestivum L.) growth, nutrient uptake, and soil biological activity. The results demonstrated that root and shoot dry biomass of wheat grown in soil mixed with biochar and combined with P. putida TSAU1 were …

Comparative Growth, Hydraulic Conductivity, And Sap Flow Responses Of Seedlings Of Two Pyrus Species To Drought Stress, Sheng Yang, Bin Xie, Liulin Li

Turkish Journal of Agriculture and Forestry

Drought is one of the major abiotic stresses limiting the advancement of the pear industry in the arid and semiarid regions of China. Currently, the production of pear seedlings mainly depends on the grafting propagation of rootstocks from Pyrus betulaefolia Bunge and Pyrus calleryana Decne. However, limited information is available on the drought stress potential of these rootstocks. Here, we conducted pot experiments with controlled watering conditions on both rootstocks' seedlings and compared their growth, plant hydraulic conductivity, and stem sap flow velocity. Both rootstocks' seedlings were challenged with three drought regimes i.e. light (LD), moderate (MD), and heavy (HD) …

The lowest both these values were found in 'Akane'. 'Red Boscop' had the highest fruit diameter (D), whereas the lowest had 'Galaxy'. Twenty-two …

Integrated Vs. Specialized Farming Systems For Sustainable Food Production: Comparative Analysis Of Systems’ Technical Efficiency In Nebraska, Maroua Afi, Jay Parsons

Department of Agricultural Economics: Faculty Publications

Complementarities between crops and livestock production have the potential to increase input use efficiency and maintain a diversified livelihood. This paper uses non-parametric data envelopment analysis (DEA) to assess the technical efficiency (TE) of integrated crop–livestock systems (ICLS) compared to specialized cropping and specialized livestock systems in the state of Nebraska, in the central United States. We classify each county of Nebraska into one of three systems according to their dominant agricultural production revenues. We use DEA to measure the TE of each county compared, first, to a group production frontier (in-system comparison) and second, to a metafrontier (cross-system comparison). …

Measuring And Preliminary Modeling Of Drift Interception By Plant Species, Jonnie B. Dunne, Shanique L. Grant, Jeffrey A. Golus, Jeffrey W. Perine, Stefan Wolf, Michael Winchell, T. Mark Ledson, Ian Whenham

West Central Research and Extension Center, North Platte

Currently, the concept of plant capture efficiency is not quantitatively considered in the evaluation of off-target drift for the purposes of pesticide risk assessment in the United States. For on-target pesticide applications, canopy capture efficiency is managed by optimizing formulations or tank-mixing with adjuvants to maximize retention of spray droplets. These efforts take into consideration the fact that plant species have diverse morphology and surface characteristics, and as such will retain varying levels of applied pesticides. This work aims to combine plant surface wettability potential, spray droplet characteristics, and plant morphology into describing the plant capture efficiency of drifted spray …

State And Transition Models For Tussock Grasslands And Woodlands Of The Kimberley: Final Project Report, Anna E. Richards, Brett Abbott, Robert Sudmeyer, Matthew Fletcher, Kath Ryan, Suzanne Prober, Philip Thomas, Pouria Ramzi, Jodie Hayward, Chris Hetherington, Karyn Reeves, Wayne J. Fletcher

Natural resources commissioned reports

The Kimberley region in north-west Western Australia is covered by extensive savanna woodlands and tussock grasslands. Approximately half the region is under pastoral leases predominately used for beef production. The Western Australian (WA) government Department of Primary Industries and Regional Development (DPIRD) undertakes lease assessment and inspection to ensure the maintenance of pastoral land condition (maintenance of perennial grass cover that supports livestock grazing and soil condition). This presents several challenges around defining land condition and practices that support and improve long-term ecological sustainability of pastoral lands. The objective of this project was to develop state and transition models (S&TMs) …

Estimating The Genetic Parameters Of Yield-Related 1 Traits Under Different Nitrogen Conditions In Maize, Semra Palali Delen, Gen Xu, Jenifer Velazquez-Perfecto, Jinliang Yang

Department of Agronomy and Horticulture: Faculty Publications

Understanding the genetic basis responding to nitrogen (N) fertilization in crop production is a long-standing research topic in plant breeding and genetics. Albeit years of continuous efforts, the genetic architecture parameters, such as heritability, polygenicity, and mode of selection, underlying the N responses in maize remain largely unclear. In this study, about n = 230 maize inbred lines were phenotyped under high N (HN) and low N (LN) conditions for two consecutive years to obtain six yield-related traits. Heritability analyses suggested that traits highly responsive to N treatments were less heritable. Using publicly available SNP genotypes, the genome-wide association study …

A Review On Potential Biofuel Yields From Cover Crops, Liangcheng Yang, Lucas D. Lamont, Shan Liu, Chunchun Guo, Shelby Stoner

Faculty Publications - Agriculture

Millions of hectares of cover crops are planted in the U.S. and European Union to manage soil erosion, soil fertility, water quality, weeds, and climate change. Although only a small percentage of cover crops are harvested, the growing cover crop planting area provides a new biomass source to the biofuel industry to produce bioenergy. Oilseed crops such as rapeseed, sunflower, and soybean are commodities and have been used to produce biodiesel and sustainable aviation fuel (SAF). Other cover crops such as cereal rye, clover, and alfalfa, have been tested on small or pilot scales to produce cellulosic ethanol, biogas, syngas, …

Application Of The Fine Sediment Biotic Index To Three Drain Tiled And Ditched Agricultural Systems In Southern Minnesota, Bailey Sanders

All Graduate Theses, Dissertations, and Other Capstone Projects

Artificial drainage is a common agricultural management technique in the United States used to remove excess water from poorly drained soils. Approximately 22.48 million hectares of crop land are drain-tiled in the United States, providing long-term economic benefits to farmers. However, artificial drainage increases sediment transport in agricultural watersheds, which can degrade aquatic systems, destroy habitats, and limit biological diversity. Biotic indices based on benthic macroinvertebrates are commonly used to assess surface water quality, but recent studies show potential in developing sediment biotic indices using benthic macroinvertebrates to estimate fine sediment in streams. The objective of this study was to …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Swine Research Industry, Alyssa Abendroth '24

Distinguished Student Work

My business research revolved around biosecurity and disease. My inquiry was led by the question How common are diseases in commercial swine units and how can they be prevented from a staff personnel standpoint?. I completed my research by gaining knowledge through experience in my internship, as well as a literature review. I could not find an explicit response to how common diseases are, but I did learn about biosecurity and disease prevention.
