Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka 2014 Iowa State University

Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka

Integrated Crop Management News

The soybean cyst nematode (SCN) is a serious yield-reducing pathogen of soybeans. It is present in many fields throughout the Midwest, wherever soybeans are grown.

To produce profitable soybean yields in fields infested with SCN, farmers should grow SCN-resistant soybean varieties. SCN-resistant soybeans can produce high yields while keeping SCN population densities from increasing.

The Impact Of Agriculture On African Civilization In The 21st Century, Andrew S. Targowski

International Conference on African Development

The purpose of this investigation is to define the impact of agriculture on African Civilization in the 21st century. The methodology is based on an interdisciplinary big-picture view of the African Civilizations developments and interdependency. Among the findings are: Sub-Saharan Africa’s only every second individual has an access to clean and enough water and electricity therefore agriculture is not productive and cannot reduce poverty and provide living sustainable environment. Practical implication: To develop agriculture as an economic engine for 65 plus nationally employed in this activity, first one must develop Integrated Infrastructure of Agriculture (IIA) at the level ...


Panicum Mosaic Virus Complex And Biofuels Switchgrass, Catherine Louise Stewart 2014 University of Nebraska - Lincoln

Panicum Mosaic Virus Complex And Biofuels Switchgrass, Catherine Louise Stewart

Biological Systems Engineering--Dissertations, Theses, and Student Research

New switchgrass (Panicum virgatum L.) cultivars are being developed for use as a biofuel pyrolysis feedstock. Viral pathogens have been reported in switchgrass, but their importance in biofuel cultivars is not well known. In 2012 surveys of five switchgrass breeding nurseries in Nebraska, plants with mottling and stunting— symptoms associated with virus infection—had an incidence of symptomatic plants within fields as high as 59%. Leaves from 120 symptomatic plants were analyzed by ELISA for Panicum mosaic virus (PMV) and four other viruses known to infect switchgrass. Most samples (87%) were positive for PMV, and fewer than 8% for the ...


Hay Supply In The U.S. Midwest, Ana Stepanovic 2014 University of Nebraska - Lincoln

Hay Supply In The U.S. Midwest, Ana Stepanovic

Dissertations and Theses in Agricultural Economics

The Renewable Fuel Standard (RFS) mandates in the Energy Independence and Security Act (EISA) of 2007 require that 36 billion gallons of renewable biofuels be produced in 2022, of which 16 billion gallons are to be from cellulosic feedstocks. This study examined supply of “other hay” (hay excluding alfalfa), based on the assumption that "other hay" is similar to grass species that might be grown as cellulosic feedstock. We have attempted to estimate the factors affecting the acreage of "other hay" in the context of a system of equations explaining allocations among all crops. For each of the three basic ...


Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores 2014 Pace University

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores

Honors College Theses

The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become ...

Particulate And Active Soil Nitrogen Fractions Are Reduced By Sheep Grazing In Dryland Cropping Systems, Upendra M. Sainju, Joy L. Barsotti, Andrew W. Lenssen, Patrick G. Hatfield

Agronomy Publications and Papers

Sheep (Ovis aries L.) grazing, a cost-effective method of weed control compared to herbicide application and tillage, may influence N cycling by consuming crop residue and weeds and returning N through feces and urine to the soil. The objective of this experiment was to evaluate the effect of sheep grazing compared to tillage and herbicide application for weed control on soil particulate and active soil N fractions in dryland cropping systems. Our hypothesis was that sheep grazing used for weed control would increase particulate and active soil N fractions compared to tillage and herbicide application. Soil samples collected at the ...

Students Creating Curriculum Change: Sustainable Agriculture And Social Justice, Angie Carter, Claudia M. Prado-Meza, Jessica Soulis, Diego Thompson

Journal of Critical Thought and Praxis

As the sustainable agriculture movement in the U.S. evolves, it faces the challenges of integration and inclusivity. Including social justice questions within sustainable agriculture education facilitates broader discussions about inequality and who benefits from this education and its practice. In this article, we present a case study in which we share our process and lessons learned from our student-led effort to integrate social justice work within the sustainable agriculture graduate curriculum at a Midwest public land-grant university. We analyze different sources and data to discuss: a) how students’ efforts can lead to curriculum development, change, and implementation; b) how ...

Bee Colony Startup And Cost Analysis, Marisela Herrera 2014 California Polytechnic State University

Bee Colony Startup And Cost Analysis, Marisela Herrera

BioResource and Agricultural Engineering

The increase in demand for European Honey bee pollination along with colony collapse disorder has caused bee pollination rental fees to greatly increase. This project intended to determine how effective and economically feasible it would be for almond growers to begin raising their own hives for pollination. It was determined the biggest challenges were organizing and finding employees who were knowledgeable about bee keeping. When looking at the cost it was clear that even with the current cost per hive the startup costs were still less than the total rental fees for a single pollination season.

Once the hives have ...

Evaluating Colostrum Quality With Niacin Supplementation In The Diet Of Dairy Cattle, Allison Marie Pike 2014 University of New Hampshire

Evaluating Colostrum Quality With Niacin Supplementation In The Diet Of Dairy Cattle, Allison Marie Pike

Student Research Projects

Dairy calves are born with a naive immune system, and must obtain passive immunity through ingestion of colostrum. Colostrum provides the newborn with antimicrobial proteins called immunoglobulins, such as immunoglobulin G (IgG), that protect the calf for the first few weeks of life. Calves that receive good quality colostrum (>50 g/L of IgG) are more likely to survive to adulthood. Niacin is a vasodilator that may increase blood flow to the mammary gland during production of colostrum in the mother. This experiment investigated the effect of niacin supplementation at a rate of 48 g/cow/day for 3 weeks ...


An Hsi Factsheet: The Environmental, Public Health, And Social Impacts Of Pig Factory Farming, Humane Society International 2014 Humane Society Institute for Science and Policy

An Hsi Factsheet: The Environmental, Public Health, And Social Impacts Of Pig Factory Farming, Humane Society International

HSI Fact Sheets: Farm Animal Protection

Since the mid-20th century, small, extensive farms have given way to massive, commercial pig production facilities. In 2009, more than 1.3 billion pigs were raised and slaughtered globally. Between 1980 and 2000, though world pork production nearly doubled, there was a decrease in the total number of farms. Large industrial farm animal production facilities, or factory farms, that often confine thousands of pigs indoors, are becoming more widespread throughout the world, particularly in developing countries. Factory farms are now responsible for more than half of all global pork production.

A significant implication of the shift toward factory farms has ...

Analysis Of Corn Distillers Dried Grains With Solubles (Ddgs) / Flour Mixtures, And Subsequent Bread Baking Trials, J. A. Saunders, Kurt A. Rosentrater, P. G. Krishnan

Agricultural and Biosystems Engineering Publications and Papers

Grains offer a variety of nutrients; it is thought that through the addition of distillers dried grains with solubles (DDGS) the fiber and protein in baked products may be improved. In this study, all-purpose flour and bread flour were tested with various DDGS substitution levels (0%, 25%, or 50% flour substitution) with the dough conditioner sodium stearoyl lactylate (SSL) (0%, 0.15%, or 0.3% flour weight basis). SSL is surfactant produced from reacting stearic acid with food grade lactic acid in the presence of sodium. Overall, as the substitution level of DDGS increased, so did protein, moisture, ash, and ...

Review: Pollination, Pollinated And Pollinators Interaction In Pakistan, Mohammad Irshad, Elizabeth Stephen

Journal of Bioresource Management

The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms. Effective pollination results in increased crop production, quality improvement and more seed production. Many fruits, vegetables, edible oil crops, stimulant crops and nuts are highly dependent on bee pollination. Worldwide value of pollinators is €153 billion (217 billion US dollars). The production value of pollinated dependent crop in Pakistan is quantified to be 1 ...
