Sugar-Enhanced And Synergistic Sweet Corn Cultivar Evaluation For Northern Indiana, 2014, Elizabeth Maynard

Purdue Fruit and Vegetable Research Reports

Indiana sweet corn acreage harvested for fresh market averaged 5,233 acres annually from 2011- 2013, with a yield of 63 hundredweight per acre (149 crates or 3.1 tons per acre) and an annual value of $13.9 million (USDA NASS, 2014).

Sweet corn fields for fresh market sales are located throughout the state. In northern Indiana, bicolor corn is most commonly grown. Varieties with improved eating quality are of interest to both producers and consumers. Producers are also interested in yield, ear size, appearance, and agronomic characteristics.

Twelve Years Of Stover Removal Increases Soil Erosion Potential Without Impacting Yield, Virginia L. Jin, Marty R. Schmer, Brian J. Wienhold, Catherine E. Stewart, Gary E. Varvel, Aaron J. Sindelar, Ronald F. Follett, Robert B. Mitchell, Kenneth P. Vogel

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

Corn (Zea mays L.) stover (non-grain aboveground biomass) in the US Corn Belt is used increasingly for livestock grazing and co-feed and for cellulosic bioenergy production. Continuous stover removal, however, could alter long-term agricultural productivity by affecting soil organic C (SOC) and soil physical properties, indicators of soil fertility and erosion potential. In this study, we showed that 12 consecutive yr of 55% stover removal did not affect mean grain yields at any N fertilizer rate (4.5, 6.3, and 6.0 Mg ha⁻¹ for 60, 120, and 180 kg N ha⁻¹ yr⁻¹, respectively) in a marginally …

Controlling Johne’S Disease: Vaccination Is The Way Forward, John Bannantine, Adel M. Talaat

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

M. avium subspecies paratuberculosis, hereafter referred to as MAP, is a significant veterinary pathogen that causes Johne’s disease in ruminants, including cattle, sheep, and goats. This chronic intestinal disease is distributed worldwide and exacts a heavy eco- nomic toll on animal producers. For example, the dairy industry incurs substantial economic losses due to reduced milk production, premature culling, and reduced slaughter value (Raizman et al., 2009). It takes years for clinical signs to appear in animals after initial infection. The bacterium is shed in high numbers in the feces during this clinical phase of disease. Transmission is by ingestion of …

Mycobacterium Avium Subspecies Paratuberculosis Recombinant Proteins Modulate Antimycobacterial Functions Of Bovine Macrophages, J. P. Bannantine, Judith R. Stabel, Elizabeth Laws, M.C.D. Cardieri, C.D. Souza

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

It has been shown that Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) activates the Mitogen Activated Protein Kinase (MAPK) p38 pathway, yet it is unclear which components of M. paratuberculosis are involved in the process. Therefore, a set of 42 M. paratuberculosis recombinant proteins expressed from coding sequences annotated as lipoproteins were screened for their ability to induce IL-10 expression, an indicator of MAPKp38 activation, in bovine monocyte-derived macrophages. A recombinant lipoprotein, designated as MAP3837c, was among a group of 6 proteins that strongly induced IL-10 gene transcription in bovine macrophages, averaging a 3.1-fold increase compared to non-stimulated macro- phages. However, …

Envelope Protein Complexes Of Mycobacterium Avium Subsp. Paratuberculosis And Their Antigenicity, Fernando L. Leite, Timothy A. Reinhardt, J. P. Bannantine, Judith R. Stabel

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

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic enteric disease of ruminant animals. In the present study, blue native PAGE electrophoresis and 2D SDS-PAGE were used to separate MAP envelope protein complexes, followed by mass spectrometry (MS) to identify individual proteins within the complexes. Identity of individual proteins within complexes was further confirmed by MS upon excision of spots from 2D SDS-PAGE gels. Among the seven putative membrane complexes observed, major membrane protein (MAP2121c), a key MAP antigen involved in invasion of epithelial cells, was found to form a complex with cysteine desulfurase (MAP2120c). …

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.

Degree-Day Prediction Models For The Flight Phenology Of Western Bean Cutworm (Lepidoptera: Noctuidae) Assessed With The Concordance Correlation Coefficient, Anthony A. Hanson, Roger D. Moon, R. J. Wright, Thomas E. Hunt, William D. Hutchinson

Department of Entomology: Faculty Publications

Western bean cutworm, Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a native, univoltine pest of corn and dry beans in North America. The current degree-day model for predicting a specified percentage of yearly moth flight involves heat unit accumulation above 10°C after 1 May. However, because the moth’s observed range has expanded into the northern and eastern United States, there is concern that suitable temperatures before May could allow for significant S. albicosta development. Daily blacklight moth catch and temperature data from four Nebraska locations were used to construct degree-day models using simple or sine-wave methods, starting dates between 1 January …

Estimation Of Efficacy Functions For Products Used To Manage Corn Rootworm Larval Injury, N A. Tinsley, P. D. Mitchell, Robert Wright, Lance J. Meinke, R. E. Estes, M. E. Gray

Department of Entomology: Faculty Publications

Maize, Zea mays L., is an economically important crop grown throughout the world. Corn rootworm, Diabrotica spp. (Coleoptera: Chrysomelidae), larvae constitute a significant economic threat to maize production in the United States, where yield losses and management costs associated with corn rootworm species exceed $1 billion annually. Furthermore, the introduction of the western corn rootworm, D. virgifera virgifera LeConte, into maize-producing regions of Europe has made managing corn rootworm larval injury an international concern. Larvae injure maize plants by feeding on root tissue and are the primary target of management activities. Products commonly used to protect root systems from injury …

Biological Control With Trichogramma Pretiosum Increases Organic Maize Productivity By 19.4%, Maria De Lourdes Corrêa Figueiredo, Ivan Cruz, Rafael Braga Da Silva, John E. Foster

Department of Entomology: Faculty Publications

Spodoptera frugiperda is a major pest causing maize yield loss in Brazil. There is therefore a need for control methods, notably for organic farming because classical pesticides are not allowed. A potential solution for organic maize is to apply the biological control agent Trichogramma pretiosum to reduce S. frugiperda populations. Here, we tested the application of one, two, or three releases of T. pretiosum. We measured plant damage ratings, egg masses parasitized, and grain yield. Results show that 79.2% of egg masses were parasited. Maize yields for parasited plots increased of 701 kg/ha versus control plots. This result equals a …

Feed The Future Ipm Innovation Lab: A Critical Role In Global Food Security, R. Muniappan, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

The World Food Summit of 1966 defined ”food security” as existing “when all people at all times have access to sufficient, safe, and nutritious food to maintain a healthy and active life.” Food insecurity is part of a continuum that includes hunger (food deprivation), malnutrition (deficiencies, imbalances, or excess of nutrients), and famine. The world faces three major challenges: (1) to match the rapidly changing demand for food, (2) to do so in ways that are environmentally and socially acceptable, and (3) to ensure that the world’s poorest people are no longer hungry. World population is expected to reach 9 …
