Buckwheat As A Cover Crop In Florida: Mycorrhizal Status, Soil Analysis, And Economic Assessment, Daria Boglaienko
Buckwheat As A Cover Crop In Florida: Mycorrhizal Status, Soil Analysis, And Economic Assessment, Daria Boglaienko
FIU Electronic Theses and Dissertations
This thesis analyses buckwheat as a cover crop in Florida. The study was designed to demonstrate: soil enrichment with nutrients, mycorrhizal arbuscular fungi interactions, growth in different soil types, temperature limitations in Florida, and economic benefits for farmers. Buckwheat was planted at the FIU organic garden (Miami, FL) in early November and harvested in middle December. After incorporation of buckwheat residues, soil analyses indicated the ability of buckwheat to enrich soil with major nutrients, in particular, phosphorus. Symbiosis with arbuscular mycorrhizal fungi increased inorganic phosphorus uptake and plant growth. Regression analysis on aboveground buckwheat biomass weight and soil characteristics showed …

Measuring The Impacts Of Agricultural Input Subsidies In Sub-Saharan Africa: Evidence From Malawi's Farm Input Subsidy Program, Gerald E. Shively, Jacob Ricker-Gilbert
Purdue Policy Research Institute (PPRI) Policy Briefs
Malawi, a small, land-locked country in south Eastern Africa has been at the forefront of the recent push to reestablish subsidies as a way of boosting agricultural production and improving food security, especially among the poor. Its programs have been widely observed, scrutinized, and emulated. This policy brief examines Malawi’s Farm Input Subsidy Program (FISP) and distills a set of key research findings drawn from research conducted recently at Purdue University.
Agricultural Development In The Northern Savannah Of Ghana, Tara N. Wood
Agricultural Development In The Northern Savannah Of Ghana, Tara N. Wood
Doctor of Plant Health Program: Dissertations and Student Research
Since declaring independence in 1957, the Republic of Ghana has become a stable constitutional democracy. Ghana’s economy has grown substantially over the past decade, yet remains primarily agrarian, accounting for 50% of the total employment and 25% of the country’s Gross Domestic Product. Smallholder rain-fed farming using rudimentary technologies dominates the agricultural sector accounting for 80% of total agricultural production. Approximately 90% of smallholder farms are less than two hectares in size, and produce a diversity of crops. The major crops cultivated in Ghana include numerous cereal, root and tuber, leguminous, fruit, vegetable and industrial crops. Maize is the most …

David A Bainbridge
Deep pipe irrigation uses a vertically placed section of pipe to deliver water to the roots of plants. This reduces evaporation and increases water use efficiency. Deep pipes can be filled by hand, drip or rainwater catchment.
Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey
Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey
Bulletins 4000 -
For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.
In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at …

The Influence Of Collective Action And Policy In The Development Of Local Food Systems, Lori Porreca
The Influence Of Collective Action And Policy In The Development Of Local Food Systems, Lori Porreca
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The modern global agrifood system has had significant negative impacts on consumers and producers. This has precipitated the rise of local food systems that are purported to improve the health and livelihoods of consumers and producers. High expectations have led to significant public and private resources dedicated to the development of local food systems. Despite this, there has been little systematic research exploring the social and institutional conditions that facilitate or frustrate local food system development.
Using a comparative case study approach, this study explored the ways local structural conditions, collective action, food system policies, and the political context affect …
Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton
Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Rapid population growth in arid regions of the western US is placing increased demand on water resources. Variability in precipitation and common occurrence of drought have promoted scrutiny of water use in urban lawns and gardens. However, few reliable measurements of water use of these landscapes exist. Quantifying the amount of water used vs. required by landscapes such as turfgrass would allow significant water conservation. Evapotranspiration (ET) is affected by biophysical factors such as: available energy, turbulent mixing, saturation deficit, soil water, and stomatal conductance. In order to simulate the water use by turfgrass, the relative importance of these processes …
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Department of Environmental Studies: Undergraduate Student Theses
Abstract Ethanol is a biofuel that has unique capabilities to mitigate global climate change by reducing greenhouse gas emissions while simultaneously supporting rural economies and decreasing the United States’ dependence on foreign oil. Currently, the state of Nebraska depends on corn ethanol, which may be unsustainable. Cellulosic ethanol is a promising alternative but it is not without its problems, including high production costs and potential environmental damage. This thesis is an attempt to understand the benefits, downfalls, and processes of corn-based and cellulosic ethanol and the potential implications to Nebraska. This research should shed some light on the current obstacles …

Changes In Producer Attitudes Towards Windbreaks In Eastern Nebraska, 1983 To 2009, Kim Tomczak
Changes In Producer Attitudes Towards Windbreaks In Eastern Nebraska, 1983 To 2009, Kim Tomczak
Department of Environmental Studies: Undergraduate Student Theses
Abstract Windbreaks are rows of trees or shrubs arranged on the landscape to reduce wind speed. In agricultural landscapes we find them as farmstead windbreaks, livestock windbreaks and field windbreaks. While farmstead and livestock windbreaks are well accepted by the agricultural community, field windbreaks are often viewed differently. A 1982 study of the attitudes of farmers in Eastern Nebraska indicated that many of the producers were around the age of 50 and that they used different types of windbreaks. This study repeated that survey in the same. When compared to data from 1982, farmers today are not educated about the …
Assesment Of Ammonia Volatility From Fall Surface-Applied Liquid Dairy Manure, Katie Campbell-Nelson
Assesment Of Ammonia Volatility From Fall Surface-Applied Liquid Dairy Manure, Katie Campbell-Nelson
Masters Theses 1911 - February 2014
Ammonia emissions from dairy and livestock operations are of significant environmental and human health concern in the United States. Conservation of ammonia from fall surface-applied manure could benefit farmers by retaining nitrogen for use by crops in the spring growing season. The primary goal of this research was to investigate a management strategy for mitigating ammonia volatility from cow manure at the time of field application with no incorporation in the fall before snow fall. The hypothesis is that application of manure in cooler fall temperatures will slow the rate of ammonia volatilization. The objective was achieved by measuring temperature …

Building Sustainable Agricultural Development Through Home-Grown School Feeding - The African Approach, Emmanuel Ohene Afoakwa, Linley Chiwona-Karltun
Professor Emmanuel Ohene Afoakwa
Proper nutrition is critical for optimal growth, cognitive development, general well-being and academic performance of children. Access to good nutrition either at home or through the educational system can contribute to the elimination of malnutrition and its associated health and developmental problems. In this regard, The 2005 UN World Summit recommended the expansion of local school feeding programmes, using home-grown foods where possible as one of the “Quick impact initiatives” to achieve the Millennium Development Goals, especially for rural areas facing the dual challenge of high chronic malnutrition and low agricultural productivity.
Risks, Farmers’ Suicides And Agrarian Crisis In India: Is There A Way Out?, Srijit Mishra
Risks, Farmers’ Suicides And Agrarian Crisis In India: Is There A Way Out?, Srijit Mishra
Srijit Mishra
Poor returns to cultivation and absence of non-farm opportunities are indicative of the larger socio-economic malaise in rural India. This is accentuated by the multiple risks that the farmer faces – yield, price, input, technology and credit among others. The increasing incidence of farmers’ suicides is symptomatic of a larger crisis, which is much more widespread. Risk mitigation strategies should go beyond credit. Long term strategies requires more stable income from agriculture, and more importantly, from non-farm sources. Private credit and input markets need to be regulated. A challenge for the technological and financial gurus is to provide innovative products …
Re-Integrating Crops And Livestock In Maine: An Economic Analysis Of The Potential For And Profitability Of Integrated Agricultural Production, Aaron K. Hoshide
Re-Integrating Crops And Livestock In Maine: An Economic Analysis Of The Potential For And Profitability Of Integrated Agricultural Production, Aaron K. Hoshide
Electronic Theses and Dissertations
This thesis examines the profitability of and sustainability indicators for potato and dairy farms in Maine integrating crops and livestock in two different ways. The first is inter-farm coupling, where two or more specialized producers are close enough to exchange manure applications for crops used as livestock feed. Land base is shared between farmers. The second is where farms are on-farm integrated. Here crops and livestock are raised on the same farm and manure is applied to cash crops and livestock feed crops. Face-to-face interviews with Maine producers were used to construct integrated and non-integrated representative budgets. Assuming …
Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville
Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville
Journal articles
Let’s start with a simple analogy: if a person eats more than they need, they gain weight. That is: if our feed inputs (kilojoules in) are greater than our outputs (exercise — kilojoules out) then we will gain weight (kilojoules in storage).That’s our fat. If, on the other hand, our feed inputs are less than our outputs, then we will lose weight.And if our inputs are the same as our outputs, our weight will remain constant. In general, the further away you are from an ‘ideal’weight, the greater the health risks. And yes, other aspects of your body management — …

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

G91-1025 Two Crops In One Year: Doublecropping, Russell Moomaw, Gary Lesoing, Charles A. Francis
G91-1025 Two Crops In One Year: Doublecropping, Russell Moomaw, Gary Lesoing, Charles A. Francis
University of Nebraska-Lincoln Extension: Historical Materials
Choice of crops, weed control, and other cultural practices for successful doublecropping are discussed here. Multiple cropping refers to growing two crops on the same field during the same year. One method of multiple cropping is doublecropping, which is when one crop is grown after the first crop is harvested. Prime USA regions for doublecropping are the eastern cornbelt, and southeastern and south central states where relatively long growing seasons and abundant rainfall occur. By contrast, shorter growing seasons and less frequent rainfall limit the potential for doublecropping in Nebraska. Irrigation is essential for successful doublecropping in Nebraska. Without irrigation, …
Agricultural Progress On The Ord, D A. Mcghie
Agricultural Progress On The Ord, D A. Mcghie
Journal of the Department of Agriculture, Western Australia, Series 4
This is the first of occasional articles describing the experimental and commercial activity on the Ord River Irrigation Area (ORIA) in Western Australia's Kimberley region.
Against a background of extensive recources of land and water, a sometimes cimatic advantage and a complementary disadvantage of a remote location, agriculture on the Ord has swung from various monocultures to a broadly based and diversified production. In 1986, the value of agricultural production on the Ord will approach values equivalent to those of the cotton era for the first time since the demise of that industry 12 years ago.
