Gene discovery for economically important traits has remained a challenging Frontier in crop genomics and breeding. The recent advances in DNA sequencing technologies and genetic analysis approaches paved the way for discovering many genes and hotspot genomic regions controlling target traits. The detection of novel genomic regions or candidate genes is very useful for plant breeders and geneticists to improve crops, dissect the genetics of complex traits, and understand the biological mechanisms of genes underpinning traits of interest. Quantitative trait loci (QTL) mapping and genome-wide association studies (GWAS) dominated recent crop gene discovery research. These studies are becoming routine activities …
Economic Contribution Of Agriculture And Food To Arkansas’ Gross Domestic Product 1997-2021, Leah English, Jennie Popp
Economic Contribution Of Agriculture And Food To Arkansas’ Gross Domestic Product 1997-2021, Leah English, Jennie Popp
Research Reports and Research Bulletins
Agricultural production, processing, and retail industries are major contributors to Arkansas’ GDP. Agriculture contributes to the state economy through direct agricultural production, value-added processing, and agricultural retail activities. The Agriculture and Food Sector, which is comprised of agricultural production, processing, and retail industries, promotes economic strength through various interactions with other industries. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with …
Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers
Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers
Graduate Student Theses, Dissertations, & Professional Papers
Pesticide drift and inadvertent contamination pose particular risks to organic production. Some organic producers have lost their crops, certification, and/or organic markets because of contamination events. Through this thesis research, I explain the perceptions and experiences that certified organic farmers in Montana have about drift and inadvertent pesticide contamination. I conducted semi-structured interviews with eleven certified organic farmers from various regions of Montana. Along with one-on-one interviews with organic farmers, interviews with industry and regulatory officials were conducted to better understand the policies and procedures that control what happens when drift occurs at the state level. Industry and regulatory official …

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Bulletins 4000 -
In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Multiple chronic conditions (MCCs) such as diabetes, hypertension, heart disease, arthritis, asthma, and common respiratory problems are prevalent in over one-fourth of Americans, and separate drugs are prescribed to manage each of the diseases. The nutritive crop seeds loaded with multiple drugs could be a cheap and sustainable alternative to drugs produced by pharmaceutical companies. Our long-term goal is to produce chickpea seeds containing comparable dosages of multiple drugs regularly prescribed for managing MCC. In this work, we conducted experiments to understand the uptake and translocation of metformin into the tissues of chickpea to demonstrate the applicability of LC–HR-ToF-MS in …

The Impact Of Genetic Changes During Crop Domestication, Petr Smýkal, Matthew N. Nelson, Jens D. Berger, Eric J.B. Von Wettberg
The Impact Of Genetic Changes During Crop Domestication, Petr Smýkal, Matthew N. Nelson, Jens D. Berger, Eric J.B. Von Wettberg
College of Agriculture and Life Sciences Faculty Publications
Humans have domesticated hundreds of plant and animal species as sources of food, fiber, forage, and tools over the past 12,000 years, with manifold effects on both human society and the genetic structure of the domesticated species. The outcomes of crop domestication were shaped by selection driven by human preferences, cultivation practices, and agricultural environments, as well as other population genetic processes flowing from the ensuing reduction in effective population size. It is obvious that any selection imposes a reduction of diversity, favoring preferred genotypes, such as nonshattering seeds or increased palatability. Furthermore, agricultural practices greatly reduced effective population sizes …

Atay V. County Of Maui, Stephanie A. George
Public Land & Resources Law Review
As genetically engineered plants become more common, questions frequently arise regarding how the plants are regulated and who can regulate them. The Ninth Circuit attempted to answer these questions through preemption doctrine. The court left the door open for states and localities to regulate genetically engineered crops that have been deregulated by the federal government. This decision will implicate the future cultivation of genetically engineered crops, and the food industry as a whole.

John E. Sawyer
Originally used to prevent scale in boilers, carpramid or thermal polyaspartate (copoly[(3-carboxypropionamide)( 2-carboxylmethyl) acetamide)] was brought to agriculture under the trade names AmiSorb and Magnet. It claimed to increase nutrient uptake through artificially increasing the volume of soil occupied by roots through increased root branching and root hair development. Under controlled hydroponic or greenhouse conditions, the use of carpramid increased nutrient uptake, some yield determining factors such as wheat tillering and in some cases, crop yield. Extensive field testing from 1996 to 1998 under various nutrient regimes, placements, forms, and timings resulted in very inconsistent performance. Averaged across all experiments …

Nitrogen Use In Iowa Corn Production, John E. Sawyer
Nitrogen Use In Iowa Corn Production, John E. Sawyer
John E. Sawyer
Nitrogen is essential for growth and reproduction of crops and is involved in many important plant biochemical processes. Nitrogen management is critical for optimal yields for corn production systems. This publication discusses long-term research done in Iowa and shows corn yields average about 60 bu/acre for continuous corn and 115 bu/acre for corn following soybean when corn is not fertilized. However, corn fertilized with N will easily yield 200 bu/acre or more. This means soil management and nitrogen fertilization practices, such as using economical optimum N rates, should be used to help optimize crop yields, use N efficiently, and enhance …
