The objective of this research was to characterize and compare the physical appearance, chemical composition, thermal and pasting properties, cooked rice texture and starch structures of the newly-developed U.S. jasmine rice from Arkansas, California and Louisiana, to be compared with jasmine rice samples from ...


The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker 2020 University of Arkansas, Fayetteville

The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Globally, rice producers are faced with the temporal problem of deciding the optimal time to being rice harvest. When harvested, paddy rice is typically at a moisture content (HMC) between 15 and 22%. Upon delivery, the rice is subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry in price/unit as the MC of grain decreases from a range of +22% to 13.5%. This study estimates an alternative linear relationship in the stair-step model ...

Behavioral Weather Insurance: Applying Cumulative Prospect Theory To Agricultural Insurance Design Under Narrow Framing, Tobias Dalhaus, Barry J. Barnett, Robert Finger 2020 ETH Zürich, Switzerland

Behavioral Weather Insurance: Applying Cumulative Prospect Theory To Agricultural Insurance Design Under Narrow Framing, Tobias Dalhaus, Barry J. Barnett, Robert Finger

Agricultural Economics Faculty Publications

Experience across many countries shows that, without large premium subsidies, crop insurance uptake rates are generally low. In this article, we propose to use the cumulative prospect theory to design weather insurance products for situations in which farmers frame insurance narrowly as a stand-alone investment. To this end, we introduce what we call "behavioral weather insurance" whereby insurance contract parameters are adjusted to correspond more closely with farmers' preferences. Depending on farmers' preferences, we find that a stochastic multiyear premium increases the prospect value of weather insurance, while a zero deductible design does not. We suggest that insurance contracts should ...

Producer Willingness To Pay For Enhanced Packaging To Prevent Postharvest Decay Of Strawberries, Brian Coffey, Valentina Trinetta, Londa Nwadike, Umut Yucel

Journal of Applied Farm Economics

We surveyed specialty crop producers in Kansas and Missouri to determine producer willingness to pay for new active packaging technology that prevents postharvest loss and increases shelf life. The survey also asked demographic questions to determine the producer and operation traits for this growing segment of production agriculture. More than half of those surveyed were female, and 60% were under 50 years of age. Smaller operations tend to utilize direct marketing and social media activity more than larger operations. Parametric willingness to pay estimates are approximately $0.39 per cardboard flat to purchase the antifungal film that increases shelf life ...


Financial Implications From Contracting Avian Influenza In A U.S. Broiler Operation, Jordan M. Shockley, Tyler Mark, Kenneth H. Burdine, Levi Russell 2020 University of Kentucky

Financial Implications From Contracting Avian Influenza In A U.S. Broiler Operation, Jordan M. Shockley, Tyler Mark, Kenneth H. Burdine, Levi Russell

Journal of Applied Farm Economics

This essay evaluates the on-farm financial impacts of an avian influenza outbreak on a U.S. commercial broiler operation. It investigates how the timing and length of the outbreak impacts farm financial performance for two different farmers, beginning and experienced. Results indicate that a beginning farmer is more susceptible to significant financial losses. Both farmers are financially impacted more when avian influenza is contracted early in the investment and when the contamination and eradication of the virus was prolonged. Furthermore, this essay highlights the problems of using standard financial measures for analyzing disease outbreaks under production contract arrangements and presents ...


Spectroscopic And Computational Studies Of The Agricultural Active Ingredient Dicamba, James Johnson 2020 University of Mississippi

Spectroscopic And Computational Studies Of The Agricultural Active Ingredient Dicamba, James Johnson

Honors Theses

3,6-dichloro-2-methoxy benzoic acid, more commonly known as Dicamba, is the active ingredient in an array of pesticides used on farmlands across the globe. Dicamba’s mode of action works by mimicking the plant hormone auxin, which is synonymous to growth hormones in mammals. The mimicking of auxin results in excessive elongation and growing, which is eventually fatal for plants when the rate of growth can no longer be sustained. Dicamba has risen in prominence in recent years due to drift damage as a result of Dicamba’s high volatility. Having the ability to identify Dicamba is crucial for the ...

Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein

UCARE Research Products

To better understand the ecology and epidemiology of the wheat curl mite (Aceria tosichella Keifer) as a vector of wheat streak mosaic virus (WSMV), it is necessary to develop a method to confine the microscopic mites and their infection to specific areas of their host plants, particularly wheat and corn. In this study, corn was the plant of interest. The device developed for this mite-confining method was made by removing the lens of a phone camera lens clip and gluing a 2.5 cm x 4.5 cm piece of wood to the other arm of the clip. Clips were ...

When you order seafood at a restaurant, do you get what you pay for? Scientists from Oceana, a non-profit marine conservation organization, conducted one of the largest seafood fraud investigations on 1,215 samples from 674 outlets in 21 states of the United States (U.S.) over the period 2010 to 2012.They found that there is, on average, a 33% probability that you do not actually get what you pay for. The share of mislabeled food was (a quite remarkable) 74% for seafood sold in sushi restaurants and 18% of seafood sold in gro-cery stores with mislabeled “red snapper ...


Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark 2020 Utah State University

Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark

All Current Publications

The importance of rotating out of a declining alfalfa stand is well established. As the alfalfa stand ages, forage yield and quality decline, while weed, insect, and disease pressures increase. Terminating the stand and growing one or more other crops for several (2–3) years allows a grower to press the reset button on a piece of ground. These years of growing another crop will result in more productive alfalfa when a new stand is planted again.


Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood 2020 Utah State University

Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood

All Current Publications

Agricultural producers are constantly looking for ways to maximize returns while reducing input costs. On dairy operations, a move from confinement feeding to pasture grazing offers the potential to reduce costs associated with harvest and storage of feed. In such a transition, producers sometimes report a decline in milk production and growth of livestock—both of which can strongly correlate to dry matter intake. Fortunately, dry matter intake is something that can be influenced by management practices. In this publication, we discuss the pasture management practices to improve dry matter intake.


Buffalograss Diversity Assessment, Collin Marshall 2020 University of Nebraska - Lincoln

Buffalograss Diversity Assessment, Collin Marshall

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Buffalograss [Buchloë dactylodes (Nutt.) Engelm. syn. Bouteloua dactyloides (Nutt.) Columbus] is a low input alternative turfgrass for the Great Plains region. Buffalograss is a dioecious stoloniferous warm season grass with wide variation of valuable traits and is well adapted for use in minimal maintenance landscapes. The obligate outcrossing nature of the species and wide variation of potentially valuable traits make buffalograss a prime candidate for cultivar improvement and genetic study. Limited information is available regarding buffalograss genetics. In effort to expand genetic resources around buffalograss, we developed buffalograss derived simple sequence repeat markers from previously available transcriptomes of buffalograss cultivars ...
