No-Till Pumpkin And Winter Squash After Winter Rye Cover Crop, Northern Indiana, 2020, Elizabeth Maynard

Midwest Vegetable Trial Reports

No-till planting of pumpkin into a killed winter rye cover crop is a system used by growers in a number of states, including Indiana. Advantages mentioned by producers in addition to soil health benefits from the cover crop include cleaner pumpkins at harvest, and in rainy seasons, less mud in the field making a more pleasant experience for customers who pick pumpkins right from the field. This paper reports on a project to develop a workable no-till system at a university research farm that can be used for demonstration and in future research to better understand and improve production practices. …

Supporting Farmer Adoption Of Sustainable Bird Management Strategies, Catherine A. Lindell

Human–Wildlife Interactions

Pest birds cause substantial and costly damage to crops. Managing birds is complex because (1) they are highly mobile, (2) they habituate quickly to many deterrents, (3) some species provide benefits to farmers by deterring and consuming pest insects, rodents, and other birds, and (4) birds are highly valued by many people. Thus, farmers have many issues to consider when developing bird management strategies. Here I discuss recent work indicating that farmer adoption of sustainable agricultural practices is more likely when practices are effective, clear guidelines for implementation are available, implementation is relatively easy, and when practices are linked, in …

Simulated Winter Incubation Of Soil With Swine Manure Differentially Affects Multiple Antimicrobial Resistance Elements, Daniel N. Miller, Madison E. Jurgens, Lisa M. Durso, Amy Schmidt

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Gastrointestinal bacteria that harbor antibiotic resistance genes (ARG) become enriched with antibiotic use. Livestock manure application to cropland for soil fertility presents a concern that ARG and bacteria may proliferate and be transported in the environment. In the United States, manure applications typically occur during autumn with slow mineralization until spring planting season. A laboratory soil incubation study was conducted mimicking autumn swine manure application to soils with concentrations of selected ARG monitored during simulated 120-day winter incubation with multiple freeze-thaw events. Additionally, the effects of two soil moistures [10 and 30% water holding capacity (WHC)] and two manure treatments …

Inaction On Lead Despite The Relevant Knowledge: Predictors, Covariates, And Outreach Implications, Alessandra Rossi, Bernabas Wolde, Pankaj Lal, Melissa Harclerode

Department of Biology Faculty Scholarship and Creative Works

Testing residential soil and paint for lead provides actionable information. By showing where and how much lead exists on the residence, it allows one to quantify risk and determine the best ways to reduce exposure along with the corresponding health and financial costs. For these reasons, several federal and state programs offer outreach to audiences on the benefits of testing residential soil and paint for lead. Not all individuals who know about lead’s adverse health effects, however, test their residence for lead, potentially limiting the actionable information that could have helped to reduce their exposure. Such individuals represent a challenge …

Livestock Indemnity Program: A Case For Managing Risk With Good Recordkeeping, Jay Parsons

Cornhusker Economics

Keeping good records is an important risk management tool for agricultural producers. Good records provide accurate, complete and consistent information that leads to better decision making. Good records also keep the farm or ranch operation in a good position to participate in USDA programs when those opportunities are available.

The Livestock Indemnity Program (LIP), one of the USDA disaster assistance programs administered by the Farm Service Agency (FSA), is an example of how good recordkeeping can be rewarded. LIP provides compensation to eligible livestock producers who have suffered livestock death losses in excess of normal mortality due to adverse weather, …

Nss, The Silencing Suppressor Of Tomato Spotted Wilt Orthotospovirus, Interferes With Ja-Regulated Host Terpenoids Expression To Attract Frankliniella Occidentalis, Jiao Du, Xiaoyu Song, Xiaobin Shi, Xin Tang, Jianbin Chen, Zhanhong Zhang, Gong Chen, Zhuo Zhang, Xuguo Zhou, Yong Liu, Deyong Zhang

Entomology Faculty Publications

Tomato spotted wilt orthotospovirus (TSWV) causes serious crop losses worldwide and is transmitted by Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). NSs protein is the silencing suppressor of TSWV and plays an important role in virus infection, cycling, and transmission process. In this research, we investigated the influences of NSs protein on the interaction of TSWV, plants, and F. occidentalis with the transgenic Arabidopsis thaliana. Compared with the wild-type Col-0 plant, F. occidentalis showed an increased number and induced feeding behavior on transgenic Arabidopsis thaliana expressing exogenous NSs. Further analysis showed that NSs reduced the expression of terpenoids synthesis-related genes and …

Consistently Biased: Documented Consistency In Self-Reported Holiday Healthfulness Behaviors And Associated Social Desirability Bias, Courtney Bir, Nicole Olynk Widmar

Department of Agricultural Economics Faculty Publications

Holiday healthfulness conversations are dominated by overindulgence of consumption and then, largely in reference to resolutions to do better, physical activity, and exercise aspirations. Consistency was found in self-reported agreement with a series of holiday healthfulness statements, across time, holidays (Thanksgiving versus Christmas), and samples of respondents. The largest proportion of respondents displaying social desirability bias (SDB) were found in response to two statements, namely “I will consume more alcohol during the holiday season than at other times of the year” at (63–66%) and “I make it a New Year’s Resolution to lose weight” (60–63%). Cheap talk was tested as …

Training Future Agriculture Professionals In Landowner–Tenant Conservation Decision-Making, Andrea Basche, Angela Carter

Michigan Tech Publications, Part 1

The landowner–tenant relationship is important to the implementation of conservation on agricultural lands. Women own or co-own a significant portion of U.S. farmland yet are underrepresented in conservation research. The next generation of agriculture professionals can benefit from first-hand experience in assisting women landowners and their tenants in navigating the complexities of conservation decision-making. This article analyzes undergraduate student perceptions of landowner–tenant relationships in conservation management through their engagement in case studies with women landowner–tenant pairs in the Western Corn Belt. Student groups were asked to complete a management improvement plan that both incorporated the agronomic and conservation goals discussed …

Intersectionality Shapes Adaptation To Social-Ecological Change, Anna Erwin, Zhao Ma, Ruxandra Popovici, Emma Patricia Salas O'Brien, Jonathan Bauchet, Nelly Ramirez Calderón, Glenn Roberto Arce Larrea

Department of Agricultural Economics Faculty Publications

People from across the Caylloma Province of Peru are adapting to social-ecological changes, such as decreasing water supplies and rapidly retreating glaciers, in different and unequal ways. In this study, we show how this inequality is intersectional; identities like gender and age compound and interact with systems of power to shape how people adapt to these changes at the individual, household, and district scales. We draw from 130 semi-structured interviews with agricultural actors and participant observations in district and regional meetings across four districts, to demonstrate how intersectionality shapes adaptation to social-ecological change. Our results show (1) what social-ecological changes …

Genome-Wide Association Mapping And Genomic Prediction Of Anther Extrusion In Cimmyt Hybrid Wheat Breeding Program Via Modeling Pedigree, Genomic Relationship, And Interaction With The Environment, Anil Adhikari, Bhoja Raj Basnet, Jose Crossa, Susanne Dreisigacker, Fatima Camarillo, Pradeep Kumar Bhati, Diego Jarquin, Yann Manes, Amir M.H. Ibrahim

Department of Agronomy and Horticulture: Faculty Publications

Anther extrusion (AE) is the most important male floral trait for hybrid wheat seed production. AE is a complex quantitative trait that is difficult to phenotype reliably in field experiments not only due to high genotype-by-environment effects but also due to the short expression window in the field condition. In this study, we conducted a genome-wide association scan (GWAS) and explored the possibility of applying genomic prediction (GP) for AE in the CIMMYT hybrid wheat breeding program. An elite set of male lines (n = 603) were phenotype for anther count (AC) and anther visual score (VS) across three field …

Development Of Mping-Based Activation Tags For Crop Insertional Mutagenesis, Alexander Johnson, Edward Mcassey, Stephanie Diaz, Jacob Reagin, Priscilla S. Redd, Daymond R. Parrilla, Hanh T. Nguyen, Adrian Stec, Lauren A.L. Mcdaniel, Thomas E. Clemente, Robert M. Stupar, Wayne A. Parrott, C Nathan Hancock

Department of Agronomy and Horticulture: Faculty Publications

Modern plant breeding increasingly relies on genomic information to guide crop improvement. Although some genes are characterized, additional tools are needed to effectively identify and characterize genes associated with crop traits. To address this need, the mPing element from rice was modified to serve as an activation tag to induce expression of nearby genes. Embedding promoter sequences in mPing resulted in a decrease in overall transposition rate; however, this effect was negated by using a hyperactive version of mPing called mmPing20. Transgenic soybean events carrying mPing-based activation tags and the appropriate transposase expression cassettes showed evidence of transposition. Expression analysis …

Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils In A Sorption Experiment, Antra Boča, Astrid R. Jacobson, Helga Van Miegroet

Aspen Bibliography

The effect tree species have on soil organic carbon (SOC) has been hotly debated but, so far, few clear patterns have emerged. One example of a differing tree species effect on SOC are aspen forests in North America, which have been found to have more stable SOC than adjacent conifer forest stands. An important source for the formation of stable organo-mineral complexes in soil is dissolved organic carbon (DOC). DOC concentrations in mineral soil are often higher under the thick O-horizons of conifer forests than under aspen forests, but this does not correspond to more stable mineral SOC. This suggests …

Functionalized Gold Nanoparticles For Sensing Of Pesticides: A Review, Wei-Bin Tseng, Ming-Mu Hsieh, Che-Hsie Chen, Tai-Chia Chiu, Wei-Lung Tseng

Journal of Food and Drug Analysis

Pesticides are a family of non-biodegradable chemical compounds which widely used in agriculture to control pests and increase yield production. However, overuse or abuse of pesticides and their metabolites may cause potential toxicity for the environment as well as human health and all other living organisms, even at deficient concentrations. Consequently, the development of sensors for monitoring these compounds is significant. Recently, nanoparticles-based sensors have been extensively employed as a potential alternative or complementary analytical tool to conventional detection methods for pesticides. Among them, gold nanoparticles (AuNPs) owing to their unique optical properties have been developed as smart sensors with …

The Economy, The Stock Market, And A Bucket Of Chicken, Timothy Meyer

Cornhusker Economics

Economists, unlike MDs and lawyers, are never able to sidestep professional questions. Whether it is at parties, or waiting to pick up kids from school, the “economy” is al-most as common as the weather for small talk. Fortunately, most economists are eager to opine on the current state of affairs, and almost as many are willing to guide laypeople to a truer understanding of what the “economy” actually is. This article will provide a definition of the economy, the Gross Domestic Product (GDP), and their importance. It will conclude by addressing the difference between the overall economy and the performance …
