Ovipositional Behavior Of The Twig Girdler (Cerambycidae: Oncideres Cingulata) On Stems Of Mockernut Hickory (Carya Tomentosa) In Arkansas, R. Tumlison, L. Serviss

Journal of the Arkansas Academy of Science

The Twig Girdler (Cerambycidae: Oncideres cingulata) is a long-horned beetle that girdles stems of certain species of trees to prepare a habitat for its offspring. The stems eventually die, break, and fall from the tree, but the beetle usually had already laid its eggs within the stems. Eggs are laid singly, almost always at growth rings or leaf bases. Because the space for the young to develop is finite, laying too many eggs could cause reproductive failure and too few eggs would be suboptimal. We hypothesized that the female laying eggs should be able to evaluate the stem and …

Does Diverse Seeding Adoption Reduce Production Costs? The Case Of Diverse Forage Seeding Strategies In West Virginia., Ivan Andres Wong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Feed and harvested forage represent a major share of production costs in Appalachian cow-calf systems, where a pronounced summer forage gap forces producers to rely on purchased hay. This thesis evaluates whether adopting diverse forage seeding strategies reduces production costs relative to the existing pasture management practice, accounting for the spatial heterogeneity of West Virginia’s production environments. The analysis proceeds in two steps. First, an unsupervised K-means clustering of 14 farms enrolled in the NRCS Conservation Innovation Grant field trial groups the farms into two agroclimatic clusters, Highland-Cool and LowlandWarm, using elevation, growing-season Growing Degree Days, growing-season precipitation, and soil …

Agricultural Productivity Under Energy Development: Insights From California, Wai Yan Siu, Sherzod B. Akhundjanov

ODU Articles

This paper examines how agricultural productivity patterns in Kern County, California, a leading region for both agricultural production and oil and gas development, co-vary with the spatial and temporal expansion of hydraulic fracturing and associated energy infrastructure. Using parcel- and county-level analyses, we characterize how agricultural productivity differs across proximity to energy development and across spatial scales. The results reveal spatially heterogeneous and scale-dependent patterns: parcel-level evidence indicates lower Enhanced Vegetation Index-based vegetation productivity within the 20-mile proximity zone around fracking wells, while county-level results show heterogeneous crop-specific yield changes during the post-expansion period. Together, these findings highlight the importance …

The Loss Function Of Usda Forecasters: Evidence From Wasde Animal Product Price Forecasts, Chad Fiechter, Siddhartha S. Bora, Todd H. Kuethe

Department of Agricultural Economics Faculty Publications

The loss function is a mathematical representation of the costs experienced by a forecaster when observed outcomes differ from what was predicted. Prior studies suggest that USDA forecasts are not optimal based on an assumed mean-zero quadratic loss function. This study proposes an alternative view of forecast evaluation, which assumes all USDA forecasts are produced to minimize the forecasters’ costs, and searches for the dimensions of the loss function under which optimality holds. We illustrate the degree to which USDA loss functions vary across a series of WASDE price forecasts. A better understanding of USDA forecasters’ costs will benefit forecasters …

Essays On The Economics Of Farmland Valuation And Investment In U.S. Agriculture, Colson Tester

Graduate Theses and Dissertations

This dissertation presents three empirical essays that collectively advance the understanding of farmland valuation in key U.S. agricultural regions, emphasizing the critical advantages of comprehensive, transaction-based data over traditional survey methods. Farmland represents a significant portion of agricultural wealth, and its accurate valuation is crucial for farmers, investors, and policymakers, influencing everything from credit access to investment strategies. Historically, research has often relied on subjective survey data, which can suffer from biases, inaccuracies, and insufficient granularity. This dissertation addresses these limitations by leveraging extensive datasets of arm’s-length farmland transactions, offering a more precise and market-driven perspective on land values. The …

Integrated Pest Management Adoption, Pesticide Handling And Knowledge Gaps Among Cotton Farmers In Tanzania: Implications For Human And Environmental Health, Sospeter Jibunge Charles

Journal of Humanities and Social Sciences

The global demand for cotton has risen significantly due to its extensive use in the textile and manufacturing industries, making it one of the most valuable cash crops worldwide. However, this growing demand for cotton production is severely threatened by the currently emerging pests which are intensified by the occurring of climate change and variability. As a result, many smallholder farmers have increasingly turned to chemical pesticides use to control the pests and maintain cotton production. But, while pesticides are effective in controlling pests and improving yields, their improper use and mismanagement pose serious risks to human health and the …

Assessing Crop Rotation Productivity, Soil Health, And Fertility, And Economic Performance, To Enhance Semi-Arid High Plains Cropping Systems Sustainability, Ezequiel Maria Villamil

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

Sustainable crop production in the semi-arid High Plains of Nebraska faces challenges from limited precipitation, high interannual variability, and economic risk. This dissertation investigates the long-term productivity, water use, soil health, and economic sustainability of dryland crop rotations, with emphasis on the role of pulses as alternatives to fallow.

Results showed that wheat–corn–fallow (W–C–F) consistently outperformed traditional wheat–fallow (W–F) and more intensified four-year rotations, providing the highest grain yields, …

Characterizing The Relationship Between Parturition In Beef Cattle And The Lunar Phase And Meteorological Factors., Caroline E. Chambers

Honors College Theses

For beef cattle, parturition is one of the most critical stages in the reproductive process. It is crucial that farmers understand the factors that may influence the timing of parturition. There is a persistent preconception that the onset of parturition is influenced by the lunar phase and weather factors. The objective of this study is to characterize the association between parturition in beef cattle, the lunar phase, and/or different weather factors such as barometric pressure and temperature. Cattle records were obtained from Chambers Family Farm in Cumberland Furnace, TN. Data was collected from 142 calvings from January 2017 to October …

The Economics Of Us Row Crop Production With Large-Scale Autonomous Machines, Joshua Strine, Chad Fiechter, James Lowenberg-Deboer

Department of Agricultural Economics Faculty Publications

Labor challenges are underpinning large multinational farm machine manufacturers' development of autonomy solutions for their large-scale machine offerings. This study simulates a linear optimization model to examine the economics of large-scale autonomous machines for a rotational maize and soybean farm in the Midwest US. Results support the hypothesis that autonomous machines can be economically viable for farms facing severe labor shortages. However, under current technology and pricing structures, conventional mechanization remains the most profitable option for farms with reliable labor. Critical factors shaping the competitiveness of autonomy include subscription fees, field efficiency, and human supervision requirements. As these factors evolve, …

Farm Efficiency And Precision Agriculture Technology, Chad Fiechter, Brady Brewer, Jennifer Ifft, Michael Boehlje

Department of Agricultural Economics Faculty Publications

Precision agriculture technology (PAT) is often viewed as a potential driver of future efficiency gains in farming. Using within-farm variation from an unbalanced panel of Kansas farms, this study examines the impact of PAT bundles on efficiency in generating gross revenue. On average, we find little evidence that these technologies improve efficiency. However, among less efficient farms, several bundles are linked to notable efficiency gains, underscoring the importance of accounting for farm heterogeneity.

From Fruit To Nut: Revisiting Pili Nut (Canarium Ovatum Engl.) Production Capacities And Value-Adding Activities In Sorsogon, Philippines, Joey Richard V. Dio, Ryan V. Dio, Dulce Corazon F. Lacson

The Philippine Agricultural Scientist

The value chain of agricultural products significantly influences their profitability and socio-economic contribution. This study developed a descriptive model of the pili (Canarium ovatum Engl.) nut value chain in Sorsogon, the primary producer in the Philippines, and the only province with large-scale commercial operations. Using a descriptive research approach, data were collected through purposive interviews with 15 key informants—farmers, processors, and traders—guided by Porter’s value-chain framework. Results indicate that Sorsogon produces about 3 times the quantity required daily (< 2,233 kg) by Bicol-based processors, leading to underutilization and post-harvest losses attributed to limited storage facilities and market linkages. The processing stage, which converts pili fruits into nuts and kernels, demonstrates the highest operational efficiency, while the trading stage remains constrained by limited market access. Stakeholders often perform overlapping functions, and traditional sun-drying methods remain common. Furthermore, an aging farming population, limited succession planning, and inconsistent implementation of food safety standards continue to pose challenges to industry growth. These inefficiencies result in reduced profitability and restrict expansion. Strengthening the value chain through improved processing systems, broader market integration, and streamlined production activities is necessary to enhance economic returns and support the sustainable growth of Sorsogon’s pili nut industry.
