Agricultural Classification Of Multi-Temporal Modis Imagery In Northwest Argentina Using Kansas Crop Phenologies, Jarrett Alexander Keifer
Agricultural Classification Of Multi-Temporal Modis Imagery In Northwest Argentina Using Kansas Crop Phenologies, Jarrett Alexander Keifer
Dissertations and Theses
Subtropical deforestation in Latin America is thought to be driven by demand for agricultural land, particularly to grow soybeans. However, existing remote sensing methods that can differentiate crop types to verify this hypothesis require high spatial or spectral resolution data, or extensive ground truth information to develop training sites, none of which are freely available for much of the world. I developed a new method of crop classification based on the phenological signatures of crops extracted from multi-temporal MODIS vegetation indices. I tested and refined this method using the USDA Cropland Data Layer from Kansas, USA as a reference. I …
Sustainable Mountain Tourism: An Analysis Of Bosnia- Herzegovina’S Wine Tourism And Its Future, John Hudelson
Sustainable Mountain Tourism: An Analysis Of Bosnia- Herzegovina’S Wine Tourism And Its Future, John Hudelson
All Faculty Scholarship for the College of the Sciences
Bosnia-Herzegovina (B-H) remains one of the most underdeveloped countries on the European Continent yet it holds great potential as a tourist destination for outdoor adventurers, history enthusiasts, and now, wine connoisseurs. The southern part of this merged nation has always been an area of wine production, but the industry has been slow to develop into a net exporter of its wines. The author and many of the industry’s supporters believe that it would be more lucrative to follow in the footsteps of its western neighbor, Croatia, and develop the wine industry through wine tourism. Utilizing historical data, interviews, analysis of …

Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Channel catfish (Ictalurus punctatus) have been grown successfully in an outdoor biofloc technology production system. Outdoor biofloc production systems in the tropic sare operated year-round, whereas the channel catfish studies were conducted only during the growing season and biofloc production tanks were harvested and idled for the winter. If an outdoor biofloc production system is to be adopted by farmers at temperate latitudes, then data gaps related to system and fish performance over the winter must be addressed. The present study was conducted to address these data gaps for channel catfish culture. Waters from a recently completed biofloc …

An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond
An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond
University of Maine Office of Research Administration: Grant Reports
The purpose of this project is to determine the relative economic values of wild bee pollinators and commercial honeybees in lowbush blueberry production for individual Maine farms. The lowbush blueberry requires insect pollination in order to set fruit. Most farmers rent colonies of the non-native honeybee for pollination services, but wild, native bees are also effective pollinators. This project aims to provide growers with the means to assess the pollination needs of individual fields and to understand the levels of pollination possible if honeybees are not available. In order to achieve these goals, the relative abundance and species diversity of …

Atomic, Crystalline And Powder Characteristics Of Treated Zirconia And Silica Powders, Mahendra Kumar Trivedi
Mahendra Kumar Trivedi
Zirconium oxide and silicon dioxide powders are selected and subjected to a non-contact Biofield energy known to be transmitted by Mahendra Kumar Trivedi. Particle sizes d50 and d99 showed up to 71.5 percent decrease indicating that the energy had caused deformation and fracture as if the powders have been subjected to high energy milling. This is also supported by increase in specific surface area up to 19.48 percent. In the present investigation Zirconium oxide and silicon dioxide powders are exposed to Bio-field. Both the exposed and unexposed powders are later characterized by various techniques. The treated powders when characterized by …

Comprehensive Characterization And Rna-Seq Profiling Of The Hd-Zip Transcription Factor Family In Soybean (Glycine Max) During Dehydration And Salt Stress, Vikas Belamkar, Nathan T. Weeks, Arvind K. Bharti, Andrew Farmer, Michelle A. Graham, Steven B. Cannon
Department of Agronomy and Horticulture: Faculty Publications
Background:
The homeodomain leucine zipper (HD-Zip) transcription factor family is one of the largest plant specific superfamilies, and includes genes with roles in modulation of plant growth and response to environmental stresses. Many HD-Zip genes are characterized in Arabidopsis (Arabidopsis thaliana), and members of the family are being investigated for abiotic stress responses in rice (Oryza sativa), maize (Zea mays), poplar (Populus trichocarpa) and cucumber (Cucmis sativus). Findings in these species suggest HD-Zip genes as high priority candidates for crop improvement.
Results:
In this study we have identified members of …

Managing China's Pastoral Lands: Current Problems And Future Prospects, Victor Roy Squires Dr
Managing China's Pastoral Lands: Current Problems And Future Prospects, Victor Roy Squires Dr
Victor Roy Squires Dr
China has the second largest area of pastoral land in the world, and these lands and their peoples play a very beneficial role in the global environment. Because of China’s huge population, rate of social reform, and economic development, the pastoral ecosystems are at a critical turning point. There is a conflict between national benefit and the land users (mainly herders) benefit. This paper introduces the scale of pastoral land, the history of its management institutions, past and current projects and programs, as well as the current framework of policy and law as relevant to land management. The challenges for …

Control Of Herbicide-Resistant Volunteer Corn In Herbicide-Resistant Soybean, Parminder Chahal
Control Of Herbicide-Resistant Volunteer Corn In Herbicide-Resistant Soybean, Parminder Chahal
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Volunteer corn is a problem weed in soybean fields because it reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these herbicides has not yet been documented. Therefore, the first objective of this study was to evaluate the response of glufosinate-, glyphosate-, and imidazolinone-resistant volunteer corn to 20 pre-emergence (PRE) and 17 post-emergence (POST) soybean herbicides. The results indicated that PRE soybean herbicides partially controlled (< 80%) volunteer corn except clomazone, while acetyl CoA carboxylase (ACCase) inhibiting herbicides provided ≥ 85% control. Germination and emergence are critical stages in weed seed establishment and persistence. Scientific literature is not available about the factors affecting germination and emergence of volunteer corn. The second objective was to determine the effects of different environmental and agronomic factors on the germination and emergence of glyphosate-resistant hybrid and volunteer corn. The results indicated that response of hybrid and volunteer corn to majority of the variables tested was similar, suggesting that volunteer corn can germinate and emerge in a wide range of climatic conditions. Majority of growers control volunteer corn when it is visible above the soybean canopy, but this can results in early season competition with soybean. The third objective was to evaluate the impact of different densities of glyphosate-resistant volunteer corn at different control timings, and late season volunteer corn emergence on soybean yields. Late season volunteer corn emergence had no significant effect on soybean yield. Yield did not decrease with all volunteer corn densities, except with the highest density (10,000 plants and 500 clumps ha-1) at all control timings. Soybean growers are looking for alternative herbicides, such …

Common Hazards In Karst Terrain, Benjamin J. Currens, Alan Fryar, Carmen T. Agouridis
Common Hazards In Karst Terrain, Benjamin J. Currens, Alan Fryar, Carmen T. Agouridis
Agriculture and Natural Resources Publications
Karst refers to terrain largely drained by subsurface conduits and caves. Karst landscapes are characterized by surface features such as springs, sinkholes, shallow depressions, and rolling hills (Figure 1). Karst regions are also known for their subsurface or below-ground features such as conduits and caves (Figure 2). What makes a karst region unique is the way runoff drains from the land. In karst regions, some of the runoff flows into surface features such as sinkholes where it then travels underground. Some of this infiltrated water re-emerges at springs (Figure 1a), and some continues moving underground.
Irrigation Tips To Conserve Water And Grow A Healthy Lawn, Gregg Munshaw, Brad Lee
Irrigation Tips To Conserve Water And Grow A Healthy Lawn, Gregg Munshaw, Brad Lee
Agriculture and Natural Resources Publications
Turfgrasses are composed of thousands of cells, all containing water, in which metabolic processes such as photosynthesis and respiration take place. Water makes up 80 to 90 percent of the total plant mass. If this level drops below 60 percent, these processes may slow and wilting will occur. Water is critically important for:
- Maintaining turgidity, which keeps plants standing upright
- Transporting nutrients and sugars through the plant
- Chemical reactions
- Transpirational cooling when water moves out of the leaves and evaporates

Mineral And Protein Blocks And Tubs For Beef Cattle, Jeff Lehmkuhler, Roy Burris, Donna M. Amaral-Phillips
Agriculture and Natural Resources Publications
Nutritional supplement blocks and tubs are convenient for beef producers, require no investment in feeding troughs and require a limited area for storing. One of the most attractive features is that they lower the labor needed to supplement livestock. Many producers use these products to provide supplemental nutrients to cattle consuming low-quality forages or as a mechanism to promote a more consistent intake of minerals. These products are also attractive to producers who have off-farm employment as they eliminate the need for daily feeding. Yet, they often come at a greater cost per unit of nutrient than more conventional feedstuffs. …

Goomig Farmlands Development Baseline Water Quality In The Lower Keep River, D L. Bennett, Richard J. George Dr
Goomig Farmlands Development Baseline Water Quality In The Lower Keep River, D L. Bennett, Richard J. George Dr
Resource management technical reports
In 2008 the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. By mid-2014 construction of almost all of the water supply, drainage, access, monitoring and other infrastructure for the 7400ha Goomig Farmlands development had substantially been completed. An important concern is the effect the Goomig Farmlands development may have on the water quality of the downstream lower Keep River aquatic environment, particularly as it relates to threatened species that inhabit or may inhabit the area. Possible increases in salinity, nutrients, suspended sediment, heavy metals and farm chemicals delivered in …

The Impact Of An Eu-Us Transatlantic Trade And Investment Partnership Agreement On Biofuel And Feedstock Markets, John C. Beghin, Jean-Christophe Bureau, Alexandre Gohin
Department of Agricultural Economics: Faculty Publications
We assess the impact of a potential TTIP bilateral free trade agreement on the EU and US bio-economies (feedstock, biofuels, by-products, and related competing crops) and major trade partners in these markets. The analysis develops a multi-market model that incorporates bilateral trade flows (US to EU, EU to US, and similarly with third countries) and is calibrated to OECD-FAO baseline for 2013–2022 to account for recent policy decisions. The major policy reforms from a TTIP involve tariff and TRQ liberalization and their direct contractionary impact on US sugar supply, EU biofuel production, and indirect negative effect on US HFCS production. …
