Department of Agronomy and Horticulture: Faculty Publications

Economic losses due to hailstorms acrossUS corn fields occur every year.Hailstorms result in leaf defoliation, decreasing photosynthetic area and impairing carbon assimilation and crop yield for all corn (Zea mays L.) development stages. However, more attention is often given to stand reductions rather than damage to stems or leaf defoliation. During the 2014 growing season, a natural hail event affected many areas of eastern Nebraska. Twelve affected corn fields were surveyed and included in this study. An injury score scale (1–5) was developed based on various injury and severity levels before the V6 (6-leaf corn growth stage) (six-collared leaves). …

Global nighttime temperatures are rising at twice the rate of daytime temperatures and pose a challenge for rice (Oryza sativa) production. High nighttime temperature (HNT) stress affects rice yield by reducing grain weight, size, and fertility. Although the genes associated with these yield parameters have been identified and characterized under normal temperatures, the genetic basis of grain weight regulation under HNT stress remains less explored. We examined the natural variation for rice single grain weight (SGW) under HNT stress imposed during grain development. A genome-wide association analysis identified several loci associated with grain weight under HNT stress. A …

Establishment Of Wildflower Islands To Enhance Roadside Health, Ecological Value, And Aesthetics, Jackson Ebbers

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Roadsides provide an abundant opportunity to increase connectivity of fragmented landscapes with diminishing floral resources for pollinating insects. The ecological value of these sites is often overlooked as quality habitat for pollinators, particularly monarch butterflies, which have been experiencing severe declines due to loss of habitat and loss of milkweeds that provide food for their larvae. Land managers across the nation are realizing the potential of roadsides to provide high quality floral resources for the benefit of insects and other wildlife. Current wildflower seed mixes used by state transportation departments are often low diversity and may only be implemented following …

Genome-Wide Association Study/ Genomic Prediction Of Cowpea Seed Protein And Black Seed Coat Color In Cowpea, Yilin Chen

Graduate Theses and Dissertations

Cowpea (Vigna unguiculata [L.] Walp) is a crucial crop in many regions, serving as a vital protein source for humans and livestock. Addressing the need to enhance its nutritional quality and make it easier to cultivate cowpeas of specific colors, this study utilized genome-wide association studies (GWAS) to identify markers associated with protein content and seed coat color patterns in cowpea.

In the protein content study, a GWAS was conducted on 161 cowpea accessions using 110,155 high-quality single-nucleotide polymorphisms (SNPs). Seven significant SNP markers were identified, all located at a locus on chromosome 8 associated with the gene Vigun08g039200, enhancing …

Turfgrass Soil Surfactants: Examining Active Ingredients, Application Strategies, And The Structure–Function Relationship In Sand-Based Putting Greens, Daniel O'Brien

Graduate Theses and Dissertations

Soil surfactants, commonly referred to as wetting agents, are a leading water management strategy for golf courses. Non-ionic block copolymers are the most common type of turfgrass soil surfactant. However, differences in the registration process and labeling requirements allow soil surfactants to enter the marketplace accompanied by far-less data compared to other products used on golf courses. This has led to considerable confusion among golf course superintendents. Three primary sources of confusion are: (i) the widely-used marketing terminology of “penetrants” and “retainers” to classify wetting agents; (ii) active ingredients which in some cases are not disclosed at all; and (iii) …

Accurate Measurement Of Field Size Is Essential For Analysis Of Smallholder Survey Data, Rica Joy Flor, Shen Yuan, Gonzalo Rizzo, Fahmuddin Agus, Anny Ruth P. Pame, Akhara Ouk, Rathmuny Then, Sokheng Keo, Virender Kumar, Particio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Context: Agronomic surveys play a vital role in identifying on-farm yield constraints and opportunities to increase productivity, input-use efficiency, and farmer profit. These surveys typically rely on farmer-reported data, where crop yield and applied inputs per hectare are estimated based on farmer-reported total harvested output and applied inputs per field and associated field size. At question is how accurate field size is, which is vital in the case of smallholders as small inaccuracies can lead to large biases in estimated yield and inputs.

Objectives: The goals of this study are to assess current approaches to determine field size …

Eberly, Jonathan J. Halvorson, Virginia L. Jin, Kyle Mankin, Andrew J. Margenot, Catherine E. Stewart, Scott Van Pelt, Merle F. Vigil

Department of Agronomy and Horticulture: Faculty Publications

Diverse patterns of climate and edaphic factors challenge detection of soil property change in the US Great Plains. Because detectable soil change can take decades, insights into the trajectory of soil properties frequently require long-term site monitoring and, where available, associated soil archives to enable comparisons with initial or baseline states. Unfortunately, few multi-decadal soil change investigations have been conducted in this region. Here, we document effects of dryland cropping on a suite of soil properties by comparing matched historic (1947) and contemporary (2018) soil samples from the Haas Soil Archive at three sites in the US Great Plains: Moccasin, …

The prevailing climate is an important factor affecting the development of the physical quality and flavor of cacao (Theobroma cacao L.) beans. The influence of harvest seasons on the physical, chemical, and flavor characteristics of cacao beans from Nakhon Si Thammarat Province, southern Thailand, was assessed. Among cacao beans, those harvested in the rainy season (R) had the highest fresh and dry weights and the lowest bean count per 100 g (87.00 ± 2.83). Although the overall fat content remained relatively constant across harvest seasons, cacao beans harvested in R exhibited a significantly higher fatty acid (C16:0, C18:1, and …

Flowering Of Spring-Planted Greens, Elizabeth Maynard, Marian M. Rodriguez-Soto, Rebecca Koetz

Midwest Vegetable Trial Reports

Greens for salad or cooking are a significant part of the spring crop mix sold at Indiana farmers' markets. The harvest period for many spring-planted greens is shortened because they flower in response to environmental conditions. This paper reports on flowering response of two varieties of arugula, collards, mizuna, two types of mustard, and shungiku, planted in mid-April through May in northern Indiana.

Imitating The “Breeder’S Eye”: Predicting Grain Yield From Measurements Of Non-Yield Traits, Hongyu Jin, Michael C. Tross, Ruijuan Tan, Linsey Newton, Ravi V. Mural, Jinliang Yang, Addie M. Thompson, James C. Schnable

Department of Agronomy and Horticulture: Faculty Publications

Plant breeding relies on information gathered from field trials to select promising new crop varieties for release to farmers and to develop genomic prediction models that can enhance the efficiency of genetic improvement in future breeding cycles. However, generating the genetic marker data required to apply genomic prediction at the early stages of a breeding program remains costly for many public-sector breeding programs as well as for many plant breeders operating in developing countries. As the pace of climate change intensifies, the time lag of developing and deploying new crop varieties requires plant breeders to make selection decisions without knowing …

Pollen-Mediated Gene Flow From Herbicide-Resistant Yellow Corn To Non-Genetically Engineered Food-Grade White Corn, Mandeep Singh, Vipan Kumar, Stevan Z. Knezevic, John L. Lindquist, Suat Irmak, Santosh Pitla, Amit J. Jhala

Department of Agronomy and Horticulture: Faculty Publications

Nebraska is the number one producer of food-grade white corn in the United States. Pollen-mediated gene flow (PMGF) from genetically engineered high alpha-amylase corn, known as Enogen corn, to food-grade white corn can have undesirable outcomes. Alpha-amylase can convert starch in white corn to sugar during or after its processing, degrading the quality of processed products. Thus, proximity to Enogen corn puts white corn production at risk. The objectives of this study were to evaluate the PMGF from herbicide-resistant yellow corn to food-grade white corn and assess the significance of wind speed and direction. Field experiments were set up using …

Variation In Leaf Chlorophyll Concentration In Response To Nitrogen Application Across Maize Hybrids In Contrasting Environments, Kyle M. Linders, Dipak K. Santra, James C. Schnable, Brandi Sigmon

Department of Agronomy and Horticulture: Faculty Publications

Leaf chlorophyll concentration was measured for 84 publicly available maize hybrids grown under three nitrogen fertilizer treatments in two contrasting environments in Nebraska. The effect of nitrogen treatment on chlorophyll response was found to be significant (p < 0.05) for both locations. In Scottsbluff, chlorophyll concentrations increased significantly with increasing nitrogen rate, while no significant difference was found between medium and high nitrogen in Lincoln. Within equivalent nitrogen treatments, chlorophyll was more abundant in Lincoln than Scottsbluff for nearly every hybrid. Hybrid response was not consistent between environments, with approximately 11% of variance explained by genotype by environment interaction.

Department of Agronomy and Horticulture: Faculty Publications

Model calibration is essential for acceptable model performance and applications. The Hybrid-Maize model, developed at the University of Nebraska-Lincoln, is a process-based crop simulation model that simulates maize growth as a function of crop and field management and environmental conditions. In this study, we calibrated and validated the Hybrid-Maize model using soil moisture and yield data from eight commercial production fields in two years. We used a new method for the calibration and multi-parameter optimization (MPO) based on kriging with modified criteria for selecting the parameter combinations. The soil moisture-related parameter combination (SM-PC3) improved simulations of soil water dynamics, but …

Powdery Mildew Of Bigleaf Hydrangea: Biology, Control, And Breeding Strategies For Resistance, Christina Jennings, Fulya Baysal-Gurel, Lisa W. Alexander

Agricultural and Environmental Sciences Faculty Research

Hydrangea macrophylla, commonly known as bigleaf, garden, French, or florist hydrangea, is the most economically important member of the Hydrangea genus, with a breeding history spanning hundreds of years. Bigleaf hydrangea breeding improvement has largely focused on aesthetic traits and there are few varieties tolerant or resistant to major diseases such as powdery mildew. Powdery mildew is an obligate biotrophic Ascomycete in the order Erysiphales represented by approximately 900 species worldwide. The disease-causing agent in hydrangeas is Golovinomyces orontii (formerly Erysiphe polygoni DC), which tarnishes the beauty, growth, and salability of bigleaf hydrangea plants, especially those packed closely in production …

A Spatio-Temporal Modelling Approach To Understand The Effect Of Urban Fruit Fly Outbreaks On Peri-Urban Orchards, Andrew Broadley, Rieks Van Klinken, Dean R. Paini, Matthew Hill, Elliot T. Howse

Horticulture Research Articles

Urban areas are well-known sources of fruit fly introduction and unmanaged populations pose a high risk of dispersal to surrounding agricultural areas. Although management of urban fruit fly populations is recognised as being important for area-wide control programmes, its relative importance is rarely quantified. Identifying possible sources of fruit fly populations is important to the success of area-wide programs, as well as to on-farm management. We developed a modelling approach to analyse the spatio-temporal connectivity of fruit fly across urban-agriculture boundaries. For a case study, we examine Mediterranean fruit fly, Ceratitis capitata, outbreaks in two fruit growing …
