Estimation Of Irrigation Requirements For Drip-Irrigated Maize In A Sub-Humid Climate, Liu Yang, Hai-Shun Yang, Jiu-Sheng Li, Yan-Feng Li, Hai-Jun Yan

Department of Agronomy and Horticulture: Faculty Publications

Drip-irrigation is increasingly applied in maize (Zea mays L.) production in sub-humid region. It is critical to quantify irrigation requirements during different growth stages under diverse climatic conditions. In this study, the Hybrid-Maize model was calibrated and applied in a sub-humid Heilongjiang Province in Northeast China to estimate irrigation requirements for drip irrigated maize during different crop physiological development stages and under diverse agro-climatic conditions. Using dimensionless scales, the whole growing season of maize was divided into diverse development stages from planting to maturity. Drip-irrigation dates and irrigation amounts in each irrigation event were simulated and summarized in 30-year simulation …

Is Less More In Food Safety Information Provision?, Kofi Britwum, Emie Yiannaka

Cornhusker Economics

The development of several niche food markets has been enabled by labels highlighting the existence of desirable or the absence of undesirable food attributes and/or production technologies, effectively targeting consumers willing to pay for this type of information. Examples include the "All Natural," “No growth promoting antibiotic," "No GMOs," and "Cage-free" food labels. In what could be viewed as an extreme example of labeling what is absent, consumers can now purchase gluten-free water (McFadden 2017). This type of "redundant" labeling seeks to exploit uninformed consumers.

Unexpected High Intragenomic Variation In Two Of Three Major Pest Thrips Species Does Not Affect Ribosomal Internal Transcribed Spacer 2 (Its2) Utility For Thrips Identification, Vivek Kumar, Aaron M. Dickey, Dakshina R. Seal, Robert G. Shatters, Lance S. Osborne, Cindy L. Mckenzie

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

The mitochondrial cytochrome oxidase I gene (mtCO1) and the ribosomal internal transcribed spacer 2 region (ITS2) are among the most widely used molecular markers for insect taxonomic characterization. Three economically important species of thrips, Scirtothrips dorsalis, Thrips palmi, and Frankliniella occidentalis were selected to examine the extent of intragenomic variation within these two marker regions in the family Thripidae, and determine if this variation would affect the utility of markers in thrips molecular diagnostics. For each species, intragenomic (within individual) variation and intergenomic (among individuals) variation was assessed by cloning and sequencing PCR-amplified copies. Intergenomic variation was generally higher than …

Identifying Ecologically Relevant Scales Of Habitat Selection: Diel Habitat Selection In Elk, Caleb P. Roberts, James W. Cain Iii, Robert D. Cox

Department of Agronomy and Horticulture: Faculty Publications

Although organisms make resource selection decisions at multiple spatiotemporal scales, not all scales are ecologically relevant to any given organism. Ecological patterns and rhythms such as behavioral and climatic patterns may provide a consistent method for identifying ecologically relevant scales of habitat selection. Using elk (Cervus canadensis) as an example species, we sought to test the ability of behavioral patterns to empirically partition diel scales for modeling habitat selection. We used model selection to partition diel scales by shifts in dominant behavior and then used resource selection probability functions to model elk habitat selection hierarchically at diel scales within seasons. …

Livestock Production And Health, Christopher Gustafson

Cornhusker Economics

As in Nebraska and other cattle-producing states, livestock are an important source of income for hundreds of millions of people living in developing countries. However, for livestock keepers in developing countries, animals are often central to multiple dimensions of the family’s existence, providing—in addition to income—important sources of energy-dense, nutrient-rich animal source foods, generating cultural status, including playing a role in family formation through wedding dowries, and serving, for some, as the household’s primary store of wealth. Livestock play all of these roles in pastoralist—semi-nomadic livestock-keeping—communi-ties. While in the past pastoralism was a relatively common way of life throughout the …

What’S Food Got To Do With It?: The Host Mother’S Role In The Cultural Education Of Students Studying Abroad In The Rabat Medina, Isabel Bonhomme

Independent Study Project (ISP) Collection

The dynamic between studentsstudying abroad and the host families with whom they stay is significant to both the study abroad experience and the way people in receiving countries view those fromthe West. Through my research, my goal was to explore and reachafundamental comprehension of this global dynamic from the Moroccan perspective.Specifically, the purpose of this study is to gain a deeper understanding of the process of cultural exchange and absorption which occurs through the use of food. I draw conclusions from information attained through formal interviews of mothers who host American students studying abroad in Rabat, and supplement this with …

Shrimp Aquaculture In Aguadulce: Impacts On Mangrove Forest Health And Shrimp Larvae Populations In Two Sites On The Salado Coastline, Nick Jickling

Independent Study Project (ISP) Collection

Shrimp aquaculture is an important industry in Republic of Panama, providing jobs and infrastructure, while supplying the country with seafood and export income. Aquaculture is accompanied by many negative impacts on mangrove ecosystems, and subsequently offshore marine stocks. The abundance and diversity of gastropods and shrimp were sampled in the Salado coastline of Aguadulce, Panama to evaluate the impacts of aquaculture disturbance on mangrove forests. Gastropods were sampled at 3 sites on 9, 100m transects in a “pristine” and disturbed forest. Shrimp were sampled using a push net in 24 sites in tide pools and abandoned shrimp ponds of the …

Do Advisors Perceive Climate Change As An Agricultural Risk? An In-Depth Examination Of Midwestern U.S. Ag Advisors’ Views On Drought, Climate Change, And Risk Management, Sarah P. Church, Michael Dunn, Nicholas Babin, Amber Saylor Mase, Tonya Haigh, Linda Stalker Prokopy

National Drought Mitigation Center: Faculty Publications

Through the lens of the Health Belief Model and Protection Motivation Theory, we analyzed interviews of 36 agricultural advisors in Indiana and Nebraska to understand their appraisals of climate change risk, related decision making processes and subsequent risk management advice to producers. Most advisors interviewed accept that weather events are a risk for US Midwestern agriculture; however, they are more concerned about tangible threats such as crop prices. There is not much concern about climate change among agricultural advisors. Management practices that could help producers adapt to climate change were more likely to be recommended by conservation and Extension advisors, …

Luchadoras: Resistencias Contra La Violencia De Género Por Las Mujeres En La Región De San Ramón, Olivia "Livey" Beha

Independent Study Project (ISP) Collection

This qualitative study describes the dynamic resiliency-building process against gender-based violence in two rural coffee-producing communities in the region of San Ramon, Nicaragua. It examines the methods and efficacy of economic empowerment and educational interventions facilitated by the Union of Agricultural Cooperatives Augusto Cesar Sandino (UCA San Ramón) in addressing gender inequality, preventing gender-based violence, and increasing access to resources for women in the cooperatives of El Privilegio and Danilo Gonzales. This complex ecology, comprised of the interactions between women, their communities, available resources, and institutions, is assessed through the lens of women’s individual perspectives as they engage in three …

Managing Opuntioid Cacti In Australia - Best Practice Control Manual For Austrocylindropuntia, Cylindropuntia And Optunia Species, M. R. Sheehan, S. Potter

Biosecurity published reports

The twenty-seven species of opuntioid cacti that are recognised as Weeds of National Significance are some of Australia's worst weeds. They grow over a wide climatic range and have impacted on pastoral and agricultural use of large tracts of land; pose an environmental risk to wildlife; and reduce aesthetic and recreational use, with direct impact on human safety.

Weedy infestations occur in all states and territories. Some are extensive, covering hundreds of thousands of hectares with a significant potential for range expansion

Over time there has been a substantial effort by government, industry, landholders and community groups to manage opuntioid …
