Infiltration And Short-Term Movement Of Nitrogen In A Silt-Loam Soil Typical Of Rice Cultivation In Arkansas, Lindsay M. Copenhaver, Mary C. Savin, David M. Miller, Peter J. Tomlinson, Kristofor R. Brye, Richard J. Norman Jan 2006

Infiltration And Short-Term Movement Of Nitrogen In A Silt-Loam Soil Typical Of Rice Cultivation In Arkansas, Lindsay M. Copenhaver, Mary C. Savin, David M. Miller, Peter J. Tomlinson, Kristofor R. Brye, Richard J. Norman

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

Rice production in Arkansas is one of the top three crop commodities in terms of cash receipts. Researchers and farmers report that nitrogen (N) needs to be managed according to a variety of factors with two important ones being soil and fertilizer type. The objectives of this experiment were to determine: 1) the degree to which floodwater-incorporated N applied as urea or as ammonium sulfate infiltrates intact cores (7.2-cm dia., 10-cm depth) containing DeWitt silt-loam soil, and 2) the distribution of N during 12 h of ponding. Inorganic-N concentrations were analyzed at 2-cm depth intervals in cores following removal of …

Production And Handling Practices For Safe Produce, Pamela L. Brady, Justin R. Morris Nov 2005

Production And Handling Practices For Safe Produce, Pamela L. Brady, Justin R. Morris

AAES Research Reports and Research Bulletins

The University of Arkansas Division of Agriculture received a grant from the USDA’s Initiative for Future Agriculture and Food Systems program to help small- and medium-sized farms become more profitable and to therefore add stability to the family farm. One approach to doing this is to help farmers growing produce reduce or eliminate safety hazards which may be associated with their products.

Production Budgets For Arkansas Wine And Juice Grapes, Emilio Noguera, Justin R. Morris, Keith Striegler, Michael Thomsen Jan 2005

Production Budgets For Arkansas Wine And Juice Grapes, Emilio Noguera, Justin R. Morris, Keith Striegler, Michael Thomsen

AAES Research Reports and Research Bulletins

Production budgets are presented for wine and juice grapes suitable for cultivation in Arkansas. Varieties examined include V. labruscana, French-American and American hybrids, V. aestivalis, V. rotundifolia, and V. vinifera. Important production considerations specific to each of these varieties are summarized. Results indicate considerable variation in profit potential among varieties. However, one or more varieties can be profitably grown in most regions of the state. With the exception of Sunbelt, V. labruscana varieties showed the least profitability. V. rotundifolia (muscadine) varieties hold promise as a new crop for the warmer southern regions of Arkansas, while Chambourcin shows strong profit potential …

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 …

Arkansas Agricultural Experiment Station Research Series

Arkansas is the leading rice-producing state in the U.S., representing just over 48% of the total U.S. production and 48.5% of the total acres planted to rice. Rice cultural practices vary across the state and across the U.S. However, due to changing political, environmental, and economic times, the practices are dynamic. This survey was initiated in 2002 to monitor how the changing times reflect the changes in the way Arkansas rice producers approach their livelihood. The survey was conducted by polling county extension agents in each of the counties in Arkansas where rice is produced. Questions included topics such as …

Use of small grain forage crops for stocker cattle production was extensively evaluated in two separate three-year research projects at the Livestock and Forestry Branch Research Station near Batesville, Ark. The first section of this Research Report presents results of a study in which 216 commercial crossbred steers (Avg. body weights 463 lb) grazed forage of wheat, oats, rye, ryegrass, wheat + rye, wheat + ryegrass, rye + ryegrass, and wheat + rye + ryegrass during the winter and spring months from 1999 through 2002. Grazing of these forages during the winter and spring provides excellent gains in stocker cattle …
