Soil Microbial Community Distributions And Disease Suppressiveness In The Coastal Plain Of Georgia, Michael J. Sabula

Electronic Theses and Dissertations

This study compared the soil microbial communities of three vegetation types in the coastal plain of Georgia: 1. crop land actively in use for agricultural production, 2. transitional grassland in early stages of secondary succession, and 3. pristine unmanaged forest land. Microbial species diversity and quantities of microbial DNA were determined from each of these vegetation types at three separate locations near Statesboro, Georgia. Length heterogeneity PCR(LH-PCR) methods and subsequent analysis of fungal, bacterial, and metazoan communities by analysis of similarity (ANOSIM) revealed high within-group similarity by vegetation type, indicating land management intensity and vegetation cover is a strong determining …

The Worlds Of Agriculture In Asia : Agricultural And Economic Development, Lorna Econg Amrinto

LSU Doctoral Dissertations

The agro-fundamentalists consider agriculture as the engine of growth while agro-pessimists argue that economic growth causes agricultural productivity. It is the main engine of growth in agriculture-based countries; less important in transforming economies; and plays the same role as other tradable sectors in urbanized countries (World Bank, 2008). This work revisits agriculture’s role in the development process within the experience of Asia where the majority of the population heavily depends on agriculture. Chapter 2 presents the results of causality tests between agriculture and economic growth in bivariate systems using the TYDL methodology. For some of agriculture-based Asia (Bhutan, Lao, Cambodia …

Propuesta De Industrialización Del Proceso De Elaboración Del Vino De Mango (Mangifera Indica L.) A Partir De La Variedad Tommy Atkins, Néstor Iván Rojas Bernal, Santiago Valencia Rodríguez

Ingeniería de Alimentos

La demanda de vino en Colombia está en aumento, pero la industria vitivinícola nacional no cuenta con la infraestructura para satisfacerla, ni en capacidad ni calidad. La producción de vinos es solo el 0,7% dentro de la industria de licores nacional. Tradicionalmente el vino se elabora de uva, pero se ha podido obtener vino a partir de otras frutas, utilizando el proceso de vinificación en blanco. En Colombia la producción de frutas tropicales se facilita por su ubicación geográfica y climas; una de ellas es el mango, que en el año 2012 tuvo una producción de 311.920t y el 20% …

LSU Master's Theses

The purpose of this thesis is to study the empirical linkages between nearby futures prices for coffee at the New York (NY) Intercontinental Exchange (ICE)/NY Board of Trade (NYBOT) and cash prices (producer and export prices) in selected Latin American countries. This theme was entertained in Fortenbery and Zapata (2004) and subsequently by Fortenbery and Zapata (2004) and Li and Fortenbery (2013). This thesis uses data from January 1990 to May 2013 and adds producer cash prices in addition to export prices, thus expanding the dataset by over a decade and adding local market cash prices relative to the first …

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams

LSU Master's Theses

Nepal is the perfect country to study all the facets of migration, sustainable agriculture and their subsequent impact on food systems. Droves of migrants are leaving rural Nepal for higher incomes to cover household daily expenses. The Government of Nepal (GON) encourages migration as a means to reduce poverty, and remittance already amounts to 25.83% of GDP, and it is expected to grow (Nepal Bastra Bank 2014, Thieme and Wyss 2005, Yang 2011). However, it is still unclear whether the mass exodus from rural areas and the growing dependence on remittance, the portion of the migrant workers' earnings sent back …

Effects Of Organic And Conventional Agricultural Practices On Soil Microbial Communities And Molecular Detection Of Soil Borne Disease, Holli K. Milner

Electronic Theses and Dissertations

Agricultural practices affect soil microbial communities and health through the input of pesticides, herbicides, fertilizers, and cycling of crop rotation. By examining the microbial community structure, we analyzed how microbial species respond to the environment that individual farms create. Early detection of soil borne disease is essential for agricultural success. However, monitoring incidence of disease based on plant growth response to pathogenic inoculation may not reveal the amount of pathogenic DNA in soil. A comparative study of tomato production systems was conducted by analysis of soil microbial community structure from four farms in Southeast Georgia for the years 2012 and …

The Effect Of Direct Payments To Rice Farming Households In Korea, Jaehyung Kim

MPA/MPP/MPFM Capstone Projects

1) Background

Rice farming is a very important agricultural policy issue for the Korean government not only because rice is a staple food for the Korean population but because rice production is also an important source of income for those involved in rice farming. The importance of rice production to the agricultural sector of Korea is indicated by the fact that 49% of Korea’s agricultural land is devoted to rice production. Therefore, Korean agricultural policy has focused on rice production issues as well as the income of farmers involved in rice production.

To support rice farming income, the Korean government …

Overexpression Of The Synthetic Chimeric Native-T-Phylloplanin-Gfp Genes Optimized For Monocot And Dicot Plants Renders Enhanced Resistance To Blue Mold Disease In Tobacco (N. Tabacum L.), Dipak K. Sahoo, Sumita Raha, James T. Hall, Indu B. Maiti

Kentucky Tobacco Research and Development Center Faculty Publications

To enhance the natural plant resistance and to evaluate the antimicrobial properties of phylloplanin against blue mold, we have expressed a synthetic chimeric native-phylloplanin-GFP protein fusion in transgenic Nicotiana tabacum cv. KY14, a cultivar that is highly susceptible to infection by Peronospora tabacina. The coding sequence of the tobacco phylloplanin gene along with its native signal peptide was fused with GFP at the carboxy terminus. The synthetic chimeric gene (native-phylloplanin-GFP) was placed between the modified Mirabilis mosaic virus full-length transcript promoter with duplicated enhancer domains and the terminator sequence from the rbcSE9 gene. The chimeric gene, expressed in transgenic …

Modeling Emergent Patterns Of Dynamic Desert Ecosystems, J. Stewart, A. Parsons, J. Wainwright, G. Okin, B. Bestelmeyer, E. Frederickson, W. Schlesinger

Ed L. Frederickson

In many desert ecosystems, vegetation is both patchy and dynamic: vegetated areas are interspersed with patches of bare ground, and both the positioning and the species composition of the vegetated areas exhibit change through time. These characteristics lead to the emergence of multi-scale patterns in vegetation that arise from complex relationships between plants, soils, and transport processes. Previous attempts to probe the causes of spatial complexity and predict responses of desert ecosystems tend to be limited in their focus: models of dynamics have been developed with no consideration of the inherent patchiness in the vegetation, or else models have been …

Prediction Of Total Phenols, Condensed Tannins, And 3-Deoxyanthocyanidins In Sorghum Grain Using Near-Infrared (Nir) Spectroscopy, L. Dykes, L. Hoffmann, O. Portillo-Rodriguez, W.L., Rooney, L.W. Rooney

Elvis A. Heinrichs

The reported high phenolic levels in sorghum have led an interest from sorghum breeding programs in developing and identifying germplasms with high phenolic levels, which require screening a large number of samples to find those with the highest levels. Since wet chemistry screening methods are slow, expensive, and destructive, the use of NIR calibration curves could be an alternative. The objectives of this project were to determine the variation range in total phenols, condensed tannins, and 3-deoxyanthocyanidin levels in a diverse set of sorghum genotypes and to assess the predictive value of NIR curves to estimate these compounds in sorghum. …

Opportunities For Energy Crop Production Based On Subfield Scale Distribution Of Profitability, Ian J. Bonner, Kara G. Cafferty, David J. Muth, Mark D. Tomer, David E. James, Sarah A. Porter, Douglas L. Karlen

Douglas L Karlen

Incorporation of dedicated herbaceous energy crops into row crop landscapes is a promising means to supply an expanding biofuel industry while benefiting soil and water quality and increasing biodiversity. Despite these positive traits, energy crops remain largely unaccepted due to concerns over their practicality and cost of implementation. This paper presents a case study for Hardin County, Iowa, to demonstrate how subfield decision making can be used to target candidate areas for conversion to energy crop production. Estimates of variability in row crop production at a subfield level are used to model the economic performance of corn (Zea mays L.) …

Comparison Study Of Different Ionic Liquid Pretreatments In Maximizing Total Reducing Sugars Recovery, Kiat Moon Lee, Gek Cheng Ngoh Dr, Adeline Seak May Chua Dr, Li Wan Yoon, Teck Nam Ang Dr., Min Gyu Lee Prof

Teck Nam Ang Dr.

A process scheme combining the most suitable ionic liquid pretreatment, followed by solid acid and enzymatic saccharification was used to maximize the reducing sugars recovery from sago waste. Three types of ionic liquids, i.e. 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1- ethyl-3-methylimidazolium acetate ([EMIM][OAc]) and 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM][(EtO)2PO2]) were evaluated based on their performance in terms of the total reducing sugars recovery, chemical cost, and pretreatment energy requirement. The results showed that all the ionic liquids assisted the saccharification processes by dissolving and depolymerizing the carbohydrates of the sago waste into shorter chain soluble oligosaccharides, as well as disrupting the biomass structure …
