Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans Jan 2005

Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Tomato (Lycopersicum esculentum ‘Early Girl’) seedling growth was evaluated in substrates containing varying proportions of ground rice hulls. Substrates were formulated containing 0, 30, 60, and 90% ground rice hulls with one-half of the treatments also treated with a surfactant. Seedling growth in two of the ground rice hull-containing substrates was generally similar to the two controls of 90% peat or 100% vermiculite. The germination percentages for all ground rice hull-containing substrates were similar to the two controls. Ground rice hulls are a viable alternative to peat and vermiculite seedling substrates.


Incorporating Glass Transition Concepts To Explain Rice Milling-Quality Reductions During The Drying Process, Derek A. Schluterman, Terry J. Siebenmorgen Jan 2005

Incorporating Glass Transition Concepts To Explain Rice Milling-Quality Reductions During The Drying Process, Derek A. Schluterman, Terry J. Siebenmorgen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Previous research has indicated that while drying rough rice using air temperatures above the glass transition temperature (Tg), head rice yield (HRY) reductions are incurred if a state transition occurs when severe intra-kernel moisture content (MC) gradients are present. State transitions can occur by extended drying using high-temperature air or by cooling kernels below Tg before sufficient tempering has occurred. The objectives of this experiment were to determine the maximum MC removal per initial drying pass and the associated tempering durations required to prevent HRY reduction. Two long-grain cultivars, ‘Francis’ and ‘Wells’, at two harvest moisture contents (HMC) were used. …

Effects Of Heating On Hydrophobicity, Viscosity, And Gelling Properties Of Soy Products, Robert S. Walnofer, Navam S. Hettiarachchy, Ronny Horax Jan 2005

Effects Of Heating On Hydrophobicity, Viscosity, And Gelling Properties Of Soy Products, Robert S. Walnofer, Navam S. Hettiarachchy, Ronny Horax

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The co-product of soybean after oil extraction is the meal, which is rich in protein. From this meal, protein concentrate and protein isolate are prepared and are commercially available as functional ingredients. Thermal treatment is the most common step applied to foods during processing. Changes in structural and functional properties can be affected by thermal or chemical treatments. The objective of this study was to evaluate the effect of heat on surface hydrophobicity, gelling properties, and viscosity of soy meal (SM), soy protein concentrate (SPC), and soy protein isolate (SPI). The soy products were subjected to heat at varying temperatures …


Sediment Loading And Water Quality Of Field Run-Off Water, J. S. Mcconnell, J. D. Mattice, B. W. Skulman, C. K. Bryant, M. Mozaffari Jan 2005

Sediment Loading And Water Quality Of Field Run-Off Water, J. S. Mcconnell, J. D. Mattice, B. W. Skulman, C. K. Bryant, M. Mozaffari

Journal of the Arkansas Academy of Science

Intensive tillage is commonly employed in many agronomic production systems in the United States. Tillage operations may include disking the field, re-smoothing the soil, seedbed formation, reducing the seedbeds, and shallow cultivation for weed control. Tillage practices in conjunction with rainfall have been linked to soil erosion, which may adversely affect the environment. The soil erosion dynamics of two large-scale production cotton fields that utilized both modern-conventional and conservation-tillage technology were examined. Studies were conducted in the cotton-producing region of southeast Arkansas in the Bayou Bartholomew watershed. Bayou Bartholomew is currently listed by the United States Environmental Protection Agency as …


The Fate If 2, 4-D In Intact Soybean (Glycine Mix), Laura Hummel, Anthony Mayer Jan 2005

The Fate If 2, 4-D In Intact Soybean (Glycine Mix), Laura Hummel, Anthony Mayer

The Journal of Undergraduate Research

About 479,000 pounds of 2,4-D (2, 4-dichlorophenoxyacetic acid) was applied to South Dakota's crops in 2000. 2,4-D can injure or reduce yield of soybean (Glycine max) if deposited on growing plants. This study determined uptake, translocation, and metabolism of ring-labeled-2,4-D in soybean at the third trifoliate (V3) stage of growth. Plants were harvested and partitioned into four parts from 1 hr (HAT)to 10 d (DAT) after treatment. Thin layer chromatography techniques were used to determine if remaining in the tissue was parent chemical or metabolite. 2,4-D uptake ranged from 39% at 1 HAT to 74% 6 DAT.By 10 DAT, translocated …

Use Of Calcium Hypochlorite As A Sanitizer For Seeds Used For Sprouting: Task #2; Impact: Improved Alfalfa Decontamination Technologies, Emily Damron, Carrie Klein, Melissa Leach, Jordan Mourot, Tom Murphy, Amy Seamans, Ryan Wilson Jan 2005

Use Of Calcium Hypochlorite As A Sanitizer For Seeds Used For Sprouting: Task #2; Impact: Improved Alfalfa Decontamination Technologies, Emily Damron, Carrie Klein, Melissa Leach, Jordan Mourot, Tom Murphy, Amy Seamans, Ryan Wilson

Inquiry: The University of Arkansas Undergraduate Research Journal

Consumption of raw or lightly cooked alfalfa sprouts has been a concern of the U.S. Food and Drug Administration (FDA) in recent years due to connections between sprouts and foodborne illnesses. Researchers have identified, contaminated seeds as the primary source of alfalfa sprouts contamination. Contamination of alfalfa seeds can originate in the field, harvesting, storing, or sprouting. Two pathogens of particular concern on alfalfa seeds are Escherichia coli 0157:H7 (E. coli) and Salmonella. These pathogens are capable of producing biofilms that provide protection for individual cells and allow for survival in otherwise hostile environments, including some disinfectant washes. Other factors …
