Industry Career Guide: Agribusiness, Roderick C. Bugador

Angelo King Institute for Economic and Business Studies (AKI)

Agribusiness is generally the commercial aspect related to agriculture or agricultural activities and its products. The Agribusiness sector is engaged in the production and operations of a farm, the manufacture and distribution of farm equipment and supplies, and the processing, storage, and distribution of farm commodities. The very core of the industry is agriculture, which is supported by the manufacturing sector and service sector. As a whole, the Agribusiness sector is quite diverse as it encompasses input production, farm operations and management, equipment and supplies manufacturing, food/non-food processing, trading, and retailing.

Effects Of Agricultural Land Use On Stream Fish Communities In Ohio, Usa, Blythe Hazellief

Browse all Theses and Dissertations

Ohio is a state dominated by agricultural land use. Such land use may directly alter stream waters and instream habitat, which may, in turn, affect fish communities. To examine the effects of agricultural land use on Ohio stream fish communities, I analyzed data compiled by the Ohio EPA, spanning 15 years and including 2,474 statewide sites. For 253 of these sites, I derived land use profiles from the 2011 USGS National Land Cover Database. While habitat quality was not correlated with agriculture, nutrient concentrations, alkalinity and total dissolved solids were positively correlated with agricultural land use within the catchment. Fish …

Patterns Of Differential Gene Expression In Adult Rotation-Resistant And Wild-Type Western Corn Rootworm Digestive Tracts, Chia-Ching Chu, Jorge A. Zavala, Joseph L. Spencer, Matías J. Curzi, Christopher J. Fields, Jenny Drnevich, Blair D. Siegfried, Manfredo J. Seufferheld

Department of Entomology: Faculty Publications

The western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) is an important pest of corn. Annual crop rotation between corn and soybean disrupts the corn-dependent WCR life cycle and is widely adopted to manage this pest. This strategy selected for rotation-resistant (RR) WCR with reduced ovipositional fidelity to corn. Previous studies revealed that RR-WCR adults exhibit greater tolerance of soybean diets, different gut physiology, and host–microbe interactions compared to rotation-susceptible wild types (WT). To identify the genetic mechanisms underlying these phenotypic changes, a de novo assembly of the WCR adult gut transcriptome was constructed and used for RNA-sequencing analyses of …

Effects Of Refuges On The Evolution Of Resistance To Transgenic Corn By The Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Jennifer Deitloff, Mike W. Dunbar, David A. Ingber, Bruce E. Hibbard, Aaron J. Gassmann

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

BACKGROUND: Diabrotica virgifera virgifera LeConte is a major pest of corn and causes over a billion dollars of economic loss annually through yield reductions and management costs. Corn producing toxins derived from Bacillus thuringiensis (Bt) has been developed to help manageD. v. virgifera.However, previous studies have demonstrated the ability of this species to evolve resistance to Bt toxins in both laboratory and field settings.

RESULTS: We used an experimental evolution approach to test the refuge strategies for delaying resistance of D. v. virgifera to corn producing Bt toxin Cry34/35Ab1. In the absence of refuges, D. v. virgifera developed resistance to …

Slavery, Agriculture, And Malaria In The Arabian Peninsula, Benjamin Reilly

Ohio University Press Open Access Books

In Slavery, Agriculture, and Malaria in the Arabian Peninsula, Benjamin Reilly illuminates a previously unstudied phenomenon: the large-scale employment of people of African ancestry as slaves in agricultural oases within the Arabian Peninsula. The key to understanding this unusual system, Reilly argues, is the prevalence of malaria within Arabian Peninsula oases and drainage basins, which rendered agricultural lands in Arabia extremely unhealthy for people without genetic or acquired resistance to malarial fevers. In this way, Arabian slave agriculture had unexpected similarities to slavery as practiced in the Caribbean and Brazil.

This book synthesizes for the first time a body of …

Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund

Human–Wildlife Interactions

Most state wildlife agencies consider public input in the management of whitetailed deer (Odocoileus virginianus) populations. In 2013, we surveyed deer hunters (n = 3,600) and landowners (n = 4,604) in southwest Minnesota to gauge their preferences for managing deer. We hypothesized a priori that, irrespective of their perceived impacts of deer, hunters would prefer deer populations to be increased and landowners would prefer deer populations to be decreased. Our findings suggest that defining stakeholder groups according to primary associations with deer (i.e., farming and hunting) accurately categorized differences in tolerance levels for deer populations in …

Off The Court, Onto The Farm, Arza E. Hammond

Graduate Student Theses, Dissertations, & Professional Papers

This work contains two separate but connected stories about developing a relationship with something larger than myself. Reaching the end of my basketball career forced me to examine my relationship with the great game of basketball and my role in it. After ending my hoops career, I spent a summer working and living on a small, organic farm. The lessons I learned from the game helped me to develop a meaningful relationship with the farm and to find a reciprocal role with the land I lived and worked on.

Growth And Biomass Accumulation Of Komatsuna Greens As Affected By Nutrient Solution Electrical Conductivity, Leah P. Malvar

Horticulture Undergraduate Honors Theses

The affects of different nutrient concentrations on komatsuna (Brassica rapa var. perviridis 'Komatsuna') grown in a nutrient film technique (NFT) hydroponic system were observed. Nutrient concentrations, measured by electrical conductivity (E.C.) in mS/cm, influenced plant height, leaf area, and plant fresh weight. The lowest measurements for each of these parameters were observed at the lowest E.C. of 1.0. mS/cm. As E.C. was increased from 1.0 to 1.2 mS/cm, measurements for shoot fresh weight and shoot height trended higher. Total leaf area increased as the E.C. was increased from 1.0 to 1.4 mS/cm, decreased as the E.C. was increased up to …

"Wake Up The Knowledge That You Have": An Assessment Of Community Food Security In Fellsmere, Florida, Susan Marie Tyler

USF Tampa Graduate Theses and Dissertations

In the global industrial agricultural system many people lack access to high-quality nutritious foods and food production techniques are often inefficient and reliant on harsh chemical inputs. While numerous strategies exist to address the disparities present in the global food system, increasingly researchers and practitioners are looking to local food systems for solutions to strengthen community food security (CFS). CFS emphasizes small-scale production strategies such as farmer's markets, community gardens, and consumer supported agriculture. As these efforts evolve, research is needed to understand how these strategies affect communities. To explore a local CFS initiative, qualitative data were collected from community …
