Use Of Endomaxx Mycorrhizal Seed Treatment To Improve Potato Production In Maine, 2017 University of Maine Cooperative Extension
Use Of Endomaxx Mycorrhizal Seed Treatment To Improve Potato Production In Maine, John M. Jemison Jr.
Cooperative Extension - Agriculture
With the increasing cost of fertilizer and the ever-decreasing supply of apatite worldwide, improving phosphorus (P) uptake should be a goal for all producers. Due to our high levels of iron and aluminum oxides in Maine soils, P efficiency is very poor. As a result, potato farmers tend to over apply P to ensure that their crop will have adequate P. Over time, this has led to increasing plant available soil test P levels. I recently requested the Maine Soil Test Lab director for potato soil tests over the past ten years. The percentage of soils testing above 40 lbs ...

Nurse Cropping In Potato Systems, John M. Jemison Jr.
Cooperative Extension - Agriculture
In the summer of 2016, a study was conducted at the Rogers Farm in Stillwater, Maine to study the effect of short-term nurse crops on potato yield and quality. The study was designed as a randomized complete block design with six replications. The study compared two sowing rates (winter rye at 100 vs. 200 lbs/ac) to 20 lbs of annual ryegrass or a check plot (no nurse crop). In addition, each of the winter rye treatments was either killed with an herbicide prior to one-pass hilling or just hilled. To address the question of how long to grow a ...

A Perspective On The Market For Agricultural Economists: Background, Trends, And Issues, Wallace E. Huffman, Larry J. Connor
This paper summarizes broad trends in the market for and training of agricultural economists, models of professional labor markets, and key issues facing the agricul- tural economics profession. The number of U.S. Ph.D. agricultural economists grew at a 7 percent rate during 1973 to 1983. An increasing share of them are being employed in business-industry. Some issues facing the profession are: potential imbal- ance in Ph.D.s supplied and demanded, type and quality of graduate education needed to meet diverse job roles of doctor- ates, demand growth potential for masters level agricultural economists
Experiment Station Expenditures: State Share And Population Effects, 2016 Iowa State University
Experiment Station Expenditures: State Share And Population Effects, John A. Miranowski, Wallace E. Huffman
There are a growing number of studies that estimate the economic returns to public sector agricultural research. The estimated rates of return from these studies should be an important input into public sector decisionmaking on the allocation of federal and state funds to agricultural research. However, there have been few attempts to develop and fit empirical models that explain resources allocated to agricultural experiment station research. Some work has been done by Peterson (1969), Guttman (1978), and by us in an earlier paper (Huffman and Miranowski).

Research, Extension, And Education Policy, Wallace E. Huffman, Marc A. Johnson
The present-day set of research-teachingextension institutions serving U.S. agriculture and households have enjoyed relatively long lives. The leading institution is the land-grant university system with a legislatively mandated mission involving federal-state-local partnerships for research, education, and extension. The secondary institution is the USDA with the Agricultural Research Service and Economic Research Service engaged in agricultural research. The early political recognition that local climates, soils, and environments play an important role in determining the local research and extension needs of farmers and rural people enabled passage of the Land-Grant College Act of 1862, the Hatch Act for state agricultural experiment ...
Reasons Youth Choose Or Do Not Choose To Be Involved In 4-H Livestock Projects In Tennessee, 2016 University of Tennessee, Knoxville
Reasons Youth Choose Or Do Not Choose To Be Involved In 4-H Livestock Projects In Tennessee, Leigh Erin Fuson
The purpose of this study was to find reasons youth choose or do not choose to be involved in 4-H livestock projects. Livestock projects are an important part of 4-H youth development because they teach life skills like responsibility and hard work. However, many youth are unable to participate or do not have the interest. This study sought to discover what motivates some youth to become involved in a livestock project and why others do not.
Focus groups were used as the data collection tool. Two groups of youth livestock participants and two groups of non-livestock participants were utilized. Themes ...
Assessing Tennessee Livestock Producers' Awareness, Attitudes And Perceptions Of Right-Of-Way Hay Harvesting, 2016 University of Tennessee, Knoxville
Assessing Tennessee Livestock Producers' Awareness, Attitudes And Perceptions Of Right-Of-Way Hay Harvesting, Sarah Joy Maccaro
In the state of Tennessee, statute 54-5-134, cutting hay along controlled access highway right-of-way, gives Tennessee agriculturalists the right to harvest hay along interstate medians and shoulders. Current maintenance is contracted out to private mowing companies and paid for by Tennessee taxpayers. Relatively few studies have been published on the topic of right-of-way hay harvesting, so this study was preliminary in nature. Through a questionnaire, this study sought to assess Hickman, Dickson, Williamson, Wilson and Rutherford county livestock producers’ current awareness, attitudes, and barriers concerning right-of-way hay harvesting as well as to conduct economic impact analyses to determine producers’ willingness ...
Photovoltaic Cooking In The Developing World, 2016 California Polytechnic State University, San Luis Obispo
Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga
The challenge of clean cooking is faced by hundreds of millions of people worldwide. We present a cooking technology consisting of a solar panel directly connected to an electric heater in a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking technologies will be the most common cooking technology for the poor. Appropriate use of insulation reduces the power demand making low-power Insulated Solar Electric Cooking systems already cost competitive.

The Role Of Interdisciplinary Scholarship And Research To Meet The Challenges Facing Agriculture In The 21st Century, Joshua Jay Miller
Doctoral Documents from Doctor of Plant Health Program
Throughout human history, scientific advancements have increased our understanding of the physical world. However, as our breadth of knowledge has increased, scholarship and research have become increasingly more specialized in order to add to the body of knowledge. University structures encourage this specialization through disciplinary learning and discovery. Although this model is necessary to continue growing the body of knowledge, the complex issues facing humanity, especially in regards to agriculture, require solutions that no single discipline can provide. These issues require an interdisciplinary approach to integrate the insights across multiple disciplines. Interdisciplinarity can be achieved through collaborative processes, but these ...
Diving Into Food Justice: Food Waste In The Anthropocene, 2016 Iowa State University
Diving Into Food Justice: Food Waste In The Anthropocene, Kathleen P. Hunt, Abby Dubisar
The Anthropocene calls for greater attention to the various and complicated ways by which humans interact with the environment and compels critical dialogue to identify and implement alternative solutions. With few exceptions, organisms (including human and more-than-human) require food as a biological need for survival. The global agrifood system has broad environmental consequences. For example, “getting food from the farm to our fork eats up 10 percent of the total U.S. energy budget, uses 50 percent of U.S. land, and swallows 80 percent of all freshwater consumed in the United States” (Gunders, 2012). Food ranks among the top ...

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, 2016 University of Montana, Missoula
Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford
STAR (STEM Teacher and Researcher) Presentations
Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that ...

A Brief History Of Corn: Looking Back To Move Forward, 2016 University of Nebraska-Lincoln
A Brief History Of Corn: Looking Back To Move Forward, Jon Derek Pruitt
Doctoral Documents from Doctor of Plant Health Program
Maize was domesticated from teosinte in Mexico some 7,000 to 10,000 years ago and quickly spread through the Americas. It has become one of the most important crops at a local and global level. Two types, Northern Flint corn and Southern Dent corns provided the basis of the genetic background of modern maize hybrids. The development of hybrids, first double-cross and later single-cross hybrids, along with a transition to high input farming provided huge yield increases, which have continued to improve with improving technology.
Increase in maize production also caused a rise in Western corn Rootworm (Diabrotica virgifera ...
Evaluation Of Fungicide Efficacy Against Cercospora Sojina And Selection For Qoi-Fungicide Resistance In Soybean, 2016 University of Tennessee - Knoxville
Evaluation Of Fungicide Efficacy Against Cercospora Sojina And Selection For Qoi-Fungicide Resistance In Soybean, Alicia Mercedes Cochran
Frogeye leaf spot (FLS) of soybean is caused by Cercospora sojina. In 2010, resistance to the quinone outside inhibitor (QoI) fungicides was reported. Since then, evaluating FLS for QoI-resistance has been of particular interest in Tennessee and other soybean-producing states. In order to determine alternative fungicide options, fungicides with solo and combination mode of action were tested in 2013-2014. The objectives were,1) to evaluate fungicide efficacy for disease control and yield protection, and 2) evaluate selection pressure for QoI-resistance. Treatments included the following fungicide groups: QoI, DMI, MBC, Chlorothalonil, QoI+DMI, SDHI+QoI, SDHI+QoI+DMI, and DMI+MBC ...
Improved Microplate Fluorometric Soil Enzyme Assay For Β-Glucosidase Detection, 2016 University of Nebraska-Lincoln
Improved Microplate Fluorometric Soil Enzyme Assay For Β-Glucosidase Detection, Emily C. Hoehn
Dissertations & Theses in Natural Resources
Soil microbes produce extracellular enzymes responsible for degrading complex organic compounds to release energy and nutrients. Measurement of soil enzymes can be considered an indicator of soil health and microbial community composition because of its sensitivity to agricultural and management practices. Fluorescence enzyme assays tend to be more sensitive than spectrophotometric (ie. colorimetric) assays and a 96-well plate has the potential capacity for high-throughput use. Development of a newly modified enzyme assay using fluorometric (4-methylumbelliferone), automated pipetting system and sonication, as well as a reduction in replicates allows for a higher sample throughput rate suitable for service laboratory use. The ...
