“Cracking” Into The Debate About Laying Hen Housing, Courtney Bir, N. M. Thompsen, Wallace Tyner, J. Hu, Nicole Olynk Widmar

Department of Agricultural Economics Faculty Publications

Livestock production systems have faced social pressures related to animal welfare; the laying hen industry also has faced changes in governing regulations/policies. This study employs experimental data to evaluate 3 confinement-housing systems: standard cages with no perches, cages with standard perches, and cages with cooled perches. Based on the cost-benefit analysis conducted of revenue less feed costs, operators are expected to have revenue, after covering feed costs, which could contribute to installation and maintenance of standard and/or cooled perches. Thus, egg producers may be able to use caged housing that incorporates perches profitably, depending on the final costs of such …

What Regional Economic Factors Drive Feedstock Cost For Cannabinoid Hemp Processors In The United States?, Tanner Mccarty

Journal of Agricultural Hemp Research

This study measures the importance of various regional economic and agronomic factors on a grower’s decision to cultivate cannabinoid (CBD) hemp flower in the United States, and its subsequent effect on CBD processor feedstock cost. I use real options analysis to recover the price of hemp flower required to trigger land use change from commodity crop production to hemp flower production across various scenarios endemic to different hemp producing regions. Results suggest the most important factors in determining the price required to trigger CBD floral hemp production are the expected yield of floral hemp and CBD concentrations within it. CBD …

Deep Kernel And Deep Learning For Genome-Based Prediction Of Single Traits In Multienvironment Breeding Trials, José Crossa, Johannes W.R. Martini, Daniel Gianola, Paulino Pérez-Rodríguez, Diego Jarquin, Philomin Juliana, Osval Antonio Montesinos López, Jaime Cuevas

Department of Agronomy and Horticulture: Faculty Publications

Deep learning (DL) is a promising method for genomic-enabled prediction. However, the implementation of DL is difficult because many hyperparameters (number of hidden layers, number of neurons, learning rate, number of epochs, batch size, etc.) need to be tuned. For this reason, deep kernel methods, which only require defining the number of layers, may be an attractive alternative. Deep kernel methods emulate DL models with a large number of neurons, but are defined by relatively easily computed covariance matrices. In this research, we compared the genome-based prediction of DL to a deep kernel (arc-cosine kernel, AK), to the commonly used …

Future Climate Change Will Have A Positive Effect On Populus Davidiana In China, Jie Li, Guan Liu, Qi Lu, Yanru Zhang, Guoqing Li, Sheng Du

Aspen Bibliography

Since climate change significantly affects global biodiversity, a reasonable assessment of the vulnerability of species in response to climate change is crucial for conservation. Most existing methods estimate the impact of climate change on the vulnerability of species by projecting the change of a species’ distribution range. This single-component evaluation ignores the impact of other components on vulnerability. In this study, Populus davidiana (David’s aspen), a tree species widely used in afforestation projects, was selected as the research subject under four future climate change scenarios (representative concentration pathway (RCP)2.6, RCP4.5, RCP6.0, and RCP8.5). Exposure components of range change as well …

The Effect Of Chronic Wasting Disease On Resident Deer Hunting Permit Demand In Wisconsin, Dane Erickson, Carson Reeling, John G. Lee

Department of Agricultural Economics Faculty Publications

Chronic wasting disease (CWD) has had a negative impact on deer license demand in Wisconsin since it was first found in the state in 2002. Prior work evaluates the effect of CWD on hunting permit sales, but only in the period immediately after the disease was discovered. We use data on hunting permit sales, permit price, and other demand shifters to estimate a model of deer permit demand for the period 1966–2015. We use the estimated model to quantify the effect of CWD on (1) hunter demand for deer permits; (2) hunter surplus from hunting; and (3) lost hunting permit …

Plant Hormones Differentially Control The Sub-Cellular Localization Of Plasma Membrane Microdomains During The Early Stage Of Soybean Nodulation, Zhenzhen Qiao, Prince Zogli, Marc Libault

Department of Agronomy and Horticulture: Faculty Publications

Phytohormones regulate the mutualistic symbiotic interaction between legumes and rhizobia, nitrogen-fixing soil bacteria, notably by controlling the formation of the infection thread in the root hair (RH). At the cellular level, the formation of the infection thread is promoted by the translocation of plasma membrane microdomains at the tip of the RH. We hypothesize that phytohormones regulate the translocation of plasma membrane microdomains to regulate infection thread formation. Accordingly, we treated with hormone and hormone inhibitors transgenic soybean roots expressing fusions between the Green Fluorescent Protein (GFP) and GmFWL1 or GmFLOT2/4, two microdomain-associated proteins translocated at the tip of the …

Performance Of 10 Slicing Cucumbers In Southwest Michigan, Ron G. Goldy

Midwest Vegetable Trial Reports

Fruit quality and yield were lower than in previous Southwest Michigan Research and Extension Center slicing cucumber trials. This may primarily be to lower bee activity affecting pollination, fruit set and fruit shape. However, from this trial Bristol, SVCS0927, LS 75-1011, Darlington, and Perfect 10 deserve consideration for further commercial planting in Southwest Michigan.

Response Of Cucumber, Yellow Squash, And Zucchini To Six Nitrogen Rates, Ron G. Goldy

Midwest Vegetable Trial Reports

There were few significant differences across the six nitrogen levels for the traits measured for all three crops. No clear trends were observed as nitrogen level was increased from 50 to 175#/acre. Better separation may have been obtained with more replication. Results indicate growers of slicing cucumber, yellow squash, and zucchini should be able to obtain adequate fruit yields using a season total of between 75 and 100#/acre nitrogen.

Performance Of 18 Fresh Market And Eight Saladette Tomato Cultivars In Southwest Michigan In 2019, Ron G. Goldy

Midwest Vegetable Trial Reports

It was again a difficult year for growing tomatoes at the Southwest Michigan Research and Extension Center. Rain shortly after field planting induced early bacterial disease infection, leading to defoliation and decreased fruit quality. The best performers in the fresh market trial were Red Snapper, Camaro, Saybrook, Jolene, and Myrtle. It was difficult to get good separation in the saladette trial. No entries rose above the others.

Evaluation Of Transplant Root Length On Bell Pepper Yield And Quality, Ron G. Goldy

Midwest Vegetable Trial Reports

Allowing bell pepper transplants to develop a taproot system was detrimental to early plant growth. However, it did not have a significant detrimental effect on most fruit yield and quality parameters measured, and by final harvest, plants of all three root length treatments had similar above ground plant weights.

The Impact Of Veterans Treatment Courts On The Community, Daniela Mettos, Amanda Leingang

Cornhusker Economics

With the United States’ ongoing presence in the Middle East and the ever-present possibility of future conflict, the commitment to tend to the unique needs of veterans returning from combat is an essential one. The number of veterans suffering from mental health issues, substance abuse disorders, and physical trauma continues to rise. With this comes an increased risk of Intimate Partner Violence (IPV), drug and alcohol abuse, and repeating criminal behavior, all of which increase the likelihood that veterans will find themselves involved in the criminal justice system at some point following their combat service.

Green Roof System Integrated Soil Methods, Jude R. Vallon, Ivan L. Guzman

Publications and Research

Large metropolitan areas like NYC are seeking to integrate sustainability into retrofitting buildings for the development of green infrastructure. Among the many environmental issues of urbanization, the UHI (urban heat island) effect and storm water runoff are of particular interest when it comes building structures. Individual buildings can contribute towards mitigating these effects with implementation of vegetative rooftops, i.e. Green Roofs. Commercial buildings are currently receiving government incentives and new constructions are required to include green roof installations. However, if existing buildings are considering the addition of a green roof on an existing roof, they have to factor in the …
