Economic And Environmental Performance Of Integrated Crop-Livestock Systems: Resilience To Uncertainties And An Opportunity For Sustainable Intensification, Maroua Afi

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Integrated crop-livestock systems are promoted as an alternative for sustainable intensification of food production. They have the potential to offer enhanced input efficiency and maintain a diversified livelihood which plays an important role in building resilience of agricultural systems. This work aims to evaluate the technical efficiency of “Integrated Crop-Livestock Systems” (ICLS), “Specialized Livestock Systems” (SLS) and “Specialized Cropping Systems” (SCS) and to identify the determinants behind inefficiencies in these systems. It also aims to assess the resilience against climate variability and market fluctuations. The first chapter provides a comparative analysis and an overview of technical efficiency assessment of farming …

Did Cover Crop Or Animal Manure Ameliorate Corn Residue Removal Effects On Soil Mechanical Properties After 10 Years?, Hans W. Klopp, Humberto Blanco-Canqui, Michael Sindelar, Virginia L. Jin, Marty R. Schmer, Richard B. Ferguson

Department of Agronomy and Horticulture: Faculty Publications

Crop residue removal may negatively affect soil mechanical properties, which are key components of soil quality. To evaluate potential long-term effects, we assessed the 10-yr impact of corn (Zea mays L.) residue removal (59 % of non-grain biomass annually) on surface soil mechanical properties (0–20 cm). We also evaluated whether adding carbon (C) amendments, such as using a winter rye (Secale cereale L.) cover crop or surface-applying cattle manure (24 Mg ha− 1 biannually) can ameliorate the effects of crop residue removal. This long-term study was under irrigated no-till continuous corn on a silt loam soil in south-central …

New Foods Produced With Genome-Editing Technique In The Global Marketplace, Stéphan Marette, Anne-Célia Disdier, John C. Beghin

Cornhusker Economics

This Cornhusker Economics article builds upon a previous Cornhusker Economics article of September 8, 2021, on the heterogenous willingness to pay (WTP) for genome edited (GenEd) apples in France and the US (Beghin, 2022). Using graphical illustration, this new article summarizes in layman's terms two related economic analyses by Marette et al. (2022) and (2023). These analyses investigate Research and Development (R&D) investment in food innovations based on New Plant Engineering Techniques (NPETs), such as GenEd and traditional hybridization methods, and then in the context of international trade. With trade, innovators compete globally with their food novelties in each other’s …

Market And Welfare Impacts Of A “Portion Size Reduction” Policy, Hanin Hosni, Konstantinos Giannakas

Cornhusker Economics

The portion size of common food items consumed at home, restaurants and fast-food establishments in the United States (US) has increased since the 1970s, with the portion size of meals and beverages in several restaurants exceeding the US Department of Agriculture (USDA) and Food and Drug Administration recommendations. Portion size has continued to grow in parallel with increasing body weights and food waste. According to USDA, 35% of the US population suffers from obesity while 40 million people are food insecure. At the same time, about 1/3 of the US food supply goes unconsumed, with 2/3 of food waste occurring …

Is Climate Change Causing The Range Contraction Of Cape Rock-Jumpers (Chaetops Frenatus)?, Gregory D. Duckworth, Raquel A. Garcia, Rheinhardt Scholtz, Res Altwegg

Department of Agronomy and Horticulture: Faculty Publications

Species distribution models often suggest strong links between climate and species' distribution boundaries and project large distribution shifts in response to climate change. However, attributing distribution shifts to climate change requires more than correlative models. One idea is to examine correlates of the processes that cause distribution shifts, namely colonization and local extinction, by using dynamic occupancy models. The Cape Rock-jumper (Chaetops frenatus) has disappeared over most of its distribution where temperatures are the highest. We used dynamic occupancy models to analyse Cape Rock-jumper distribution with respect to climate (mean temperature and precipitation over the warmest annual quarter), …

Dicamba Off-Target Movement From Applications On Soybeans At Two Growth Stages, Greg R. Kruger, Guilherme S. Alves, Kasey Schroeder, Jeffrey A. Golus, Daniel B. Reynolds, Darrin M. Dodds, Ashli E. Brown, Bradley K. Fritz, Wesley C. Hoffmann

Department of Agronomy and Horticulture: Faculty Publications

The objective of this study was to evaluate dicamba off-target movement during and after applications over soybean at two growth stages. Dicamba-tolerant soybean [Glycine max (L.) Merr.] at V3 and R1 growth stages in Nebraska and Mississippi fields were treated with diglycolamine salt of dicamba (560 g ae ha⁻¹), potassium salt of glyphosate (1260 g ae ha⁻¹), and a drift-reducing adjuvant (0.5% v v⁻¹). Filter papers positioned outside the sprayed area were used to determine primary movement and air samplers positioned at the center of sprayed area were used to calculate dicamba flux …

Seasons, Stress, Salience, And Support For Cooperative Groundwater Management, Jordan Suter, Todd Guilfoos, Karina A. Schoengold

Cornhusker Economics

Common property resources (CPR) are defined as resources where one person’s use affects what is available to others (either now or in the future). One example of a CPR is a shared aquifer, where multiple users have access to the groundwater. Economic researchers have shown that with a CPR, there are economic benefits to regulating the use of the resource, and that well-designed regulation increases the sustainability of agricultural-based economies that rely on CPRs. Many such regulations exist, and examples include allocation limits in some of Nebraska’s Natural Resources Districts and Kansas’s Groundwater Management Districts, as well as groundwater fees …

A Follow-Up Survey To Assess Stakeholders’ Perspectives On Weed Management Challenges And Current Practices In Nebraska, Usa, Shawn T. Mcdonald, Debalin Sarangi, Jennifer M. Rees, Amit J. Jhala

Department of Agronomy and Horticulture: Faculty Publications

Stakeholders across the state of Nebraska, USA, were surveyed in 2019–2020 to assess problem weeds and weed management practices in agronomic crops. A total of 420 complete responses were obtained across four Nebraska districts (Northeast, Panhandle, Southeast, and West Central). Accumulated across the state, 65.5% of farmed or scouted crop ground in Nebraska was under no-till production, with the major crops being corn and soybean representing 39.3% and 30.7% of agronomic crop production area, respectively. Palmer amaranth, horseweed, waterhemp, kochia, and giant ragweed were ranked the most problematic weeds. In a 2014–2015 survey, Palmer amaranth was the sixth most problematic …

The Evolving Definition Of Plant Cell Type, Sahand Amini, Jeffrey J. Doyle, Marc Libault

Department of Agronomy and Horticulture: Faculty Publications

In 1665 Robert Hooke, looking at cork through his microscope, discovered that plants are composed of elementary structures he named “cells”. Variation in the expression of a single genome in a complex eukaryotic organism guides the initiation, maturation, physiology, and biochemistry of cells with different shapes and sizes, playing different structural and functional roles in space and time. How many kinds of cells—”cell types”— an organism possesses of course depends on the organism’s cellular complexity, but the plasticity within a cell type fuels the emergence of the concept of cell state (Figure 1). The transition between cell states is driven …

Shortening Harvest Interval, Reaping Benefits? A Study On Harvest Practices In Oil Palm Smallholder Farming Systems In Indonesia, Rosanne E. De Vos, Lisa Nurfalah, Fatima A. Tenorio, Ya Li Lim, Juan Pablo Monzon, Christopher R. Donough, Hendra Sugianto, Asri A. Dwiyahreni, Nurul L. Winarni, Nadia Mulani, Gilang Ramadhan, Muhammad Ali Imran, Antonius P. Tito, Pandu Sulistiawan, Muhammad Khoirul, Rana Farrasati, Iput Pradiko, Patricio Grassini, Maja Slingerland

Department of Agronomy and Horticulture: Faculty Publications

CONTEXT: Smallholders are responsible for a large share of global palm oil production. Yet, in Indonesia, the main palm oil producing country, smallholders’ yields remain low. Better management practices, including short harvest interval (HI, the number of days between two harvest rounds), could help to raise smallholder yields. However, at present, HI is long in smallholder fields and the drivers underlying this phenomenon are poorly understood.

OBJECTIVE: We explored agronomic, socio-economic, and institutional factors that underlie harvesting practices in independent oil palm smallholder farming systems in Indonesia to assess scope for sustainable intensification through shorter HI and reduced …

Exotic Herbivores And Fire Energy Drive Standing Herbaceous Biomass But Do Not Alter Compositional Patterns In A Semiarid Savanna Ecosystem, Virginia D. Preiss, Carissa L. Wonkka, Devan A. Mcgranahan, Alexandra G. Lodge, Matthew B. Dickinson, Kathleen L. Kavanagh, Heath D. Starns, Douglas R. Tolleson, Morgan L. Treadwell, Dirac L. Twidwell Jr, William E. Rogers

Department of Agronomy and Horticulture: Faculty Publications

Questions: Fire regime alterations are pushing open ecosystems worldwide past tipping points where alternative steady states characterized by woody dominance prevail. This reduces the frequency and intensity of surface fires, further limiting their effectiveness for controlling cover of woody plants. In addition, grazing pressure (exotic or native grazers) can reinforce woody encroachment by potentially reducing fine-fuel loads. We investigated the effects of different fire energies on the herbaceous plant community, together with mammalian wildlife herbivory (exotic and native combined) exclusion, to inform best management practices.

Location: Texas semi-arid savanna, southern Great Plains, USA.

Methods: We conducted an …

Particle Drift Potential Of Mesotrione And Rimsulfuron Plus Thifensulfuron-Methyl Tank Mixture In A Low-Speed Wind Tunnel, Milan Brankov, Guilherme Sousa Alves, Bruno Canella Vieira, Milos Zaric, Greg R. Kruger

West Central Research and Extension Center, North Platte

Particle drift happens during herbicide application when droplets travel outside the intended site. Different nozzles produce various range of droplets, so they play a very important role in coverage and drift occasions. When nozzles produce small droplets, the potential for off-target movement is very high. Another important factor determining particle drift is the distance between crops. Wind velocity gives the energy to herbicide particles to move away from the target place. Therefore, a drift simulation of herbicide (mesotrione and rimsulfuron plus thifensulfuron-methyl mixture) was done in a wind tunnel, using different nozzles Extended Range (XR) and Turbo TeeJet Induction (TTI). …

Your Farm’S Financial Condition And Profitability Revisited, Matthew Stockton, Shannon Sand

Cornhusker Economics

Looking at December futures contracts, corn prices may have reached a high and are tending to recede. If they stay higher, producers will likely have a good year. Still, if they tend to decline, which is possible given current carryover and supply projections, prices may stabilize or decline as we approach harvest. Those with multiperil crop insurance in areas with lower yields, e.g., droughtstricken areas with sufficiently high enough levels of coverage, will benefit from the February projected price of $5.91/bu. For the past two seasons, fall prices exceeded projected prices in the spring, making selling at harvest an attractive …

Targeted Sequencing Of The Panicum Miliaceum Gene Space And Genotyping Of Variant Sites From Population Genetics Studies, Combined In A Single Assay, As A Tool For Broomcorn Millet Assisted Breeding, Gabriele Magris, Serena Foria, Silvano Ciani, Dipak K. Santra, Ombretta Polenghi, Virna Cerne, Michele Morgante, Gabriele Di Gaspero

Department of Agronomy and Horticulture: Faculty Publications

Broomcorn millet (Panicum miliaceum L.) is a prehistorical cereal, today cultivated as a minor crop with low yields but with a renewed interest for its high water use effciency and gluten-free grains. To reverse the downward trend in broomcorn millet cultivation, the crop needs genetic improvement and creation of novel genetic variation to increase productivity. In order to facilitate genomics-assisted breeding, we designed a reduced representation genome-sequencing assay that investigates 1.8% of the nuclear DNA in a targeted and reproducible way, with an intensity of genomic sampling that is a direct function of local recombination rate. We used this …

Indigenous Lakadong Turmeric Of Meghalaya And Its Future Prospects, Manjit Kumar Ray, Dipak K. Santra, Piyush Kumar Mishra, Saurav Das

Department of Agronomy and Horticulture: Faculty Publications

Turmeric (Curcuma longa) has long been used in traditional Indian medicine. India accounts for 80% of total global turmeric production. Lakadong turmeric gets its name from the tiny village of Lakadong, which is located in the foothills of the Jaintia Hills in Meghalaya, India. It is known for having a high curcumin content of more than 7%, as opposed to 2 - 4% in regular varieties. The tribes of this region brought Lakadong turmeric from the forest and domesticated it for medicinal purposes centuries ago. Growth in local coal industries and a gradual decline in the market have …

Assessing Determinants Of Participation In Conservation Programs In The U.S., Manita Ale, Simanti Banerjee, Taro Mieno, Karina A. Schoengold

Cornhusker Economics

In order to generate ecosystem services (ES) from privately owned intensively managed agricultural land, the United States Department of Agriculture (USDA)’s Farm Service Agency (FSA) and Natural Resources Conservation Service (NRCS) have implemented many conservation programs such as the Conservation Reserve Program (CRP), Conservation Stewardship Program (CSP), and Environmental Quality Incentives Program (EQIP), to name a few. These programs provide financial and technical assistance to farmers and ranchers to adopt land management practices that generate ES.

Effect Of Cutting Management On The Forage Production And Quality Of Tepary Bean (Phaseolus Acutifolius A. Gray), Travis W. Witt, Brian K. Northup, Timothy G. Porch, Santos Barrera, Carlos A. Urrea

Department of Agronomy and Horticulture: Faculty Publications

Tepary bean (Phaseolus acutifolius A. Gray) is an underutilized drought tolerant annual legume, originating from the Sonoran Desert, that may be a beneficial forage/hay for beef cattle in the Southern Great Plains of the US (SGP). The SGP has erratic rainfall and periods of intermittent drought exacerbated by high summer temperatures. In 2020 and 2021, a split-plot design was used to evaluate 13 genotypes of tepary bean and a forage soybean (control) at El Reno, OK, USA to compare production of plant biomass and forage nutritive value parameters under seven harvest regimes. Genotypes were used as the main plot …

Intertemporal Preferences Or (In)Attention To Future Costs: Identifying Factors Influencing Variation In Health Behaviors, Christopher Gustafson

Cornhusker Economics

When you have the urge to buy a fancy coffee drink at your favorite coffee place, do you think about alternative future uses of the money that you would spend on the drink? If, in the end, you decide to forego buying the drink to save money, you have, by definition, considered what you are giving up now—the drink—in order to have the money later, but many people may not consider the future opportunities they forego when they make decisions now. Research suggests that this asymmetric attention to immediate versus future opportunity costs— the benefits that we give up when …

Examining Potential Trade-Offs Between Pest Management And Pollination To Sunflower Production In Nebraska, Luis Ochoa Cadena

Department of Entomology: Dissertations, Theses, and Student Research

Sunflower (Helianthus annuus) is cultivated for oil and seed production worldwide, and the United States produces 2.5% of the world’s oilseed sunflower primarily grown in the Great Plains. In 2022, oilseed and confectionary U.S. sunflower production increased by 48 and 44%, respectively, compared to last year's records. However, sunflower production can be seriously compromised by insect pests. The red sunflower seed weevil (Smicronyx fulvus LeConte) is considered the most serious pests in North America and causes severe economic damage yearly. On the other hand, native bees contribute substantially to sunflower yield. Currently, insecticide applications are the primary tool to suppress …

Exploring The Presence Of Nonlinear Deterministic Dynamics In Commodity Prices, Sagar Dahal

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Determining whether commodity prices (and volatility) are driven by linear stochastic processes or low-dimensional nonlinear deterministic dynamics (“chaos”) is crucial for policymaking, forecasting, production, storage, investment, risk management, and hedging decisions. Previous studies that used Lyapunov exponents and correlation dimensions to identify chaotic structures in price series may be unreliable in practical applications because these methods rely on asymptotic properties that require large, noiseless data which is often not available. We applied nonlinear time series analysis approaches to empirically detect the underlying market dynamics using the daily futures prices of ten agricultural commodities. We used phase space reconstruction to reconstruct …
