Supersweet Sweet Corn Cultivar Evaluation For Northern Indiana, 2019, Elizabeth Maynard

Midwest Vegetable Trial Reports

Indiana sweet corn for fresh market was harvested from 3,580 acres and 426 farms in 2017 (USDA NASS, 2019a). Indiana ranked 16th among states for production of all sweet corn and produced about 0.6% of the nation’s total in 2017 (USDA NASS, 2018). Sweet corn fields for fresh market sales are located throughout the state. In northern Indiana, bicolor corn is most commonly grown. Varieties with improved eating quality are of interest to both producers and consumers. Producers are also interested in yield, ear size, appearance, and agronomic characteristics.

This paper reports on fifteen bicolor, four yellow, and one white …

“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 …

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 …

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.

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.

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.

Spring Black Rot-Resistant Cabbage Cultivar Evaluation, Chris Smigell, John Strang, John Snyder

Midwest Vegetable Trial Reports

Fourteen green fresh-market cabbage cultivars were evaluated at the University of Kentucky horticultural farm in Lexington in a replicated trial to evaluate their performance in Central Kentucky. Cultivars were listed in seed catalogs as having black rot (Xanthomonas campestris) resistance or tolerance. Cultivars were grown on bare soil following University of Kentucky recommendations to commercial cabbage growers. Plants were not inoculated with X. campestris, and Badge SC bactericide was applied once early in the season. ‘Lucky Ball’ was the top-performing early-season cultivar, being consistently tender, sweet to slightly sweet, and having little to no sulfur aftertaste. Its …

Effects Of Removing Background Soil Reflectance Pixels From Vegetative Index Maps For Characterization Of Corn Responses To Experimental Treatments, Ana Morales, Robert L. Nielsen, James J. Camberato

Purdue GIS Day

In contrast to traditional data collection methods that require manual sampling, vegetative index (VI) maps derived from unmanned aerial vehicles (UAV) imagery are a potential tool to characterize temporal and spatial treatment effects in a more efficient and non-destructive way. Remotely-sensed reflectance data from a growing corn crop contains pixel values associated with the above-ground plant tissue (e.g., leaves, stalks, tassels) and the underlying soil features. Background soil reflectance data potentially reduces the effectiveness of VI for characterizing crop responses to experimental treatments. Removing background soil image pixels from the larger image dataset should improve that effectiveness. The objective of …

Molecular Phylogeny Implemented In An Introductory Plant Classification Course, Chao Cai, Jo Ann Banks

Libraries Faculty and Staff Presentations

Plant classification is one of the core components in undergraduate programs related to plant sciences. Traditionally plant classification courses primarily introduce morphology-based taxonomy because of practical needs in the field. However, the publication of new plant classification systems by Angiosperm Phylogeny Group (APG) using molecular phylogeny methods leads to the trends of using molecular evidence (DNA barcode) for plant identification. In our introductory plant classification course, we included a two-week module (lectures and labs) to introduce key concepts and fundamental skills in molecular phylogeny. Week 1 included concepts of evolutionary tree thinking, data mining in NCBI using BLAST search, and …

Memories Of Life On The Farm: Through The Lens Of Pioneer Photographer J. C. Allen, Frederick Whitford, Neal Harmeyer

Purdue University Press Book Previews

John Calvin Allen, professionally known as J. C., worked as a photographer for Purdue University from 1909-1952, and operated his own photography business until his death in 1976. The J. C. Allen photographs represent an historical account of the transition from pioneer practices to scientific methodologies in agriculture and rural communities. During this major transitional period for agriculture, tractors replaced horses, hybrid corn supplanted open-pollinated corn, and soybeans changed from a novelty crop to regular rotation on most farms. During this time, purebred animals with better genetic pedigrees replaced run-of-the-mill livestock, and systematic disease prevention in cattle, swine, and poultry …

Subsurface Mimo: A Beamforming Design In Internet Of Underground Things For Digital Agriculture Applications, Abdul Salam

Computer Information Technology Faculty Publications

In underground (UG) multiple-input and multiple-output (MIMO), the transmit beamforming is used to focus energy in the desired direction. There are three different paths in the underground soil medium through which the waves propagates to reach at the receiver. When the UG receiver receives a desired data stream only from the desired path, then the UG MIMO channel becomes three path (lateral, direct, and reflected) interference channel. Accordingly, the capacity region of the UG MIMO three path interference channel and degrees of freedom (multiplexing gain of this MIMO channel requires careful modeling). Therefore, expressions are required for the degree of …

Willingness To Pay Of Nigerian Poultry Producers And Feed Millers For Aflatoxin-Safe Maize, Andrew M. Johnson, Tahirou Abdoulaye, Bamikole Ayedun, Joan R. Fulton, Nicole Olynk Widmar, Akande Adebowale, Ranajit Bandyopadhyay, Victor Manyong

Department of Agricultural Economics Faculty Publications

Dietary aflatoxin exposure is a widespread problem in the developing world and causes severe negative health consequences to humans and livestock animals. A new biological control product, called Aflasafe, has been introduced in Nigeria to mitigate aflatoxin contamination of maize in the field and in storage. No known prior work has estimated how much African agribusinesses using maize for animal feed will pay for aflatoxin-safe maize. This study measured the levels of Aflasafe awareness, surveyed current aflatoxin management practices, and estimated, using choice experiments, willingness to pay (WTP) for aflatoxin-safe maize by Nigerian poultry producers and feed millers. Data was …

Investigating The Drivers Of Farm Diversification Among U.S. Fruit And Vegetable Operations, Nicholas A. Lancaster, Ariana P. Torres

Purdue University Libraries Open Access Publishing Fund

Diversification of an agricultural operation’s crop mix is considered an environmental and financial management strategy. Environmentally, crop diversification can stabilize the ecosystem via the introduction of biodiversity, allowing for more rapid response to physical and social changes. Economically, crop mix diversification can mitigate risk. Though there are environmental and economic benefits of crop diversification, little economic work has been conducted on crop diversification outside of the row crop industry. This study estimated how internal and external factors affect crop diversification among fruit and vegetable (FV) operations. External factors included access to markets and land; internal factors included farmer beliefs and …

Assessment Of Household Food Security In Fish Farming Communities In Ghana, Akua S. Akuffo, Kwamena Quagrainie

Department of Agricultural Economics Faculty Publications

The Government of Ghana and international NGOs have been encouraging the adoption of fish farming to alleviate poverty and food insecurity through training workshops, financial contributions and creation of a fisheries ministry. Nevertheless, there is no study on how these efforts have influenced the household’s welfare, particularly their nutritional quality. Based on this, our objective is to identify the ways through which fish farming impacts the household’s nutritional quality. We hypothesize that engaging in fish farming will increase steady income flow and access to fish for the household’s direct consumption. We adopted the Propensity Score Matching (PSM) approach in a …

A Theoretical Model Of Underground Dipole Antennas For Communications In Internet Of Underground Things, Abdul Salam, Mehmet C. Vuran, Xin Dong, Christos Argyropoulos, Suat Irmak

Computer Information Technology Faculty Publications

The realization of Internet of Underground Things (IOUT) relies on the establishment of reliable communication links, where the antenna becomes a major design component due to the significant impacts of soil. In this paper, a theoretical model is developed to capture the impacts of change of soil moisture on the return loss, resonant frequency, and bandwidth of a buried dipole antenna. Experiments are conducted in silty clay loam, sandy, and silt loam soil, to characterize the effects of soil, in an indoor testbed and field testbeds. It is shown that at subsurface burial depths (0.1-0.4m), change in soil moisture impacts …

Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward

Purdue Journal of Service-Learning and International Engagement

Engagement Methods for International Food Security (YDAE 49100) provided an opportunity for enrolled students to travel abroad to Cap-Haitïen, Haiti. As both a course in agriculture and a service-learning study abroad, the overarching goal was to inspire, engage, and teach Purdue and Haitian students through service learning in agriculture. This was done by developing a project with teammates during the fall semester that was then presented to students in Haiti during the International Agri-Symposium at Université Antenor Firmin over winter break.

Determinants Of Catch Sales In Ghanaian Artisanal Fisheries, Kwamena Quagrainie, Jingjie Chu

Department of Agricultural Economics Faculty Publications

The study examined the determinants of catch sales of artisanal fishers through wealthy middle women in fishing communities of Ghana, often known as fish mothers or “fish mongers”. The effects of selected variables were examined with a double hurdle model. Self-financing was found to negatively affect the fishers’ sale of fish catch through fish mothers. The fishers were 19% less likely to sell to fish mothers if they self-finance, and that self-financing will result in a 10% downward unconditional change on the percentage of fish sold to the fish mothers. Factors that positively influenced the sale of fish catch through …
