2005 Crop Variety Sowing Guide For Western Australia, Jenny Garlinge

Bulletins 4000 -

The Crop Variety Sowing Guide attempts to present all the information that is necessary for you to make the best choice of variety for each of the major crops. As well as varietal characteristics and performance, it contains information on herbicide resistance, disease, agronomic factors, deliveries and marketing.

Much of the information presented this year is on the basis of the ‘Agzone’. This is an amalgamation of the traditional ‘region zone cells’which were coded H1 to L5 according to length-of-growing season zones from north to south (1 to 5) and rainfall regions, based on annual average rainfall, from west to …

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 …

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 …

Science-Based Organic Farming 2005: Toward Local And Secure Food Systems, Charles A. Francis, Twyla Hansen, Peter Skelton

Publications from the Center for Applied Rural Innovation (CARI)

Organic farming includes growing food and fiber — animals, agronomic crops, horticultural fruits and vegetables, related products — as one dynamic and rapidly evolving component of our complex U.S. food system. Even as more farmers are moving toward organic certification and participation in an environmentally sound and economically lucrative market, questions arise about the long-term social impacts and sustainability of a set of practices that has gone from a movement to an industry. Consolidations in the organic trade have brought multinational corporations to the table, as they have observed a grassroots activity that has grown by 20% per year for …

Ec05-185 Grazing Winter Wheat In Nebraska, Tom Holman, Drew J. Lyon, David D. Baltensperger, Ivan G. Rush, Ray E. Weed

University of Nebraska-Lincoln Extension: Historical Materials

Grazing cattle on winter wheat, often prior to grain harvest, is common throughout the southern Great Plains. Grazing generates about $50 million in income for Texas wheat producers and reduces the risk of growing wheat by providing a substantial income source other than grain. Benefits can be realized by grazing prior to the primary environmental risk period for drought, heat stress, and hail, all of which frequently reduce grain yield while having limited impact on forage production. Cattle also are grazed on winter wheat fields in western Nebraska and the surrounding region. Typically in Nebraska, fall forage would be used …

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 …

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

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

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

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 …

Aeration Strategies And Fan Cost Comparisons For Wheat In Mid-South Production Regions, Thomas C. Bridges, Michael D. Montross, Samuel G. Mcneill

Biosystems and Agricultural Engineering Faculty Publications

Numerous factors influence the sizing of aeration fans for summer-harvested crops. Thirty years of weather data for Lexington, Kentucky, were analyzed and the cost of aeration was compared for two axial fans (afan1, afan2) and one centrifugal fan (cfan1). Aeration costs were defined as the sum of the following components: the cost of owning the fan, the cost of electricity for operating the fan, a cost for wheat shrinkage during aeration, and a cost for dry matter loss (DML). The fans were selected to deliver airflow rates of approximately one, two, and three times the recommended aeration rate of 0.11 …

Agronomical Evaluation Of Six Species Of Forage Grass Tolerant To Salinity In The Tamborada Region, Bladimir Vargas Rojas

Theses and Dissertations

Six forage grass species from the United States were evaluated for salinity tolerance and growth performance. A randomized block design was used with six repetitions of five furrows each to maintain experimental consistency. The study was conducted in the Tamborada region of Cochabamba, Bolivia from December 2003 through June 2004. Results indicated that significant differences exist between species (Pr<0.01). The species Elymus cinereus and Agropyron elongatum demonstrated the best performance regarding plant height, achieving heights of 35.4 cm and 32.7 cm respectively. Festuca arundinacea and Agropyron elongatum obtained larger percent coverage than the other species with 79.59% and 76.53% respectively. These species also exceed the others in production of green forage (1500.00 kg/ha and 13985.80 kg/ha) as well as in production of dry matter (5000.70 kg/ha and 4862.85 kg/ha). They are recommended for production in the region of Tamborada, Cochabamba, Bolivia.

Key Grazing Levels (Foo Targets) For Pasture And Sheep Management, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Food On Offer (FOO) is the amount of pasture in front of an animal, and is measured in kilograms Dry Matter per hectare. Managing pastures to key grazing levels - or FOO targets - can result in improved production of grazing systems in Mediterranean environments which are characterized by slow winter growth, peak spring growth and dry summers. These targets vary according to what production response is required.

This information sheet illustrates key target FOO for sheep grazing annual pastures during autumn and spring.

Effect Of Control Plot Density, Control Plot Arrangement, And Assumption Of Random Or Fixed Effects On Nonreplicated Experiments For Germplasm Screening Using Spatial Models, Boi Sebolai, Jeffrey F. Pedersen, D. B. Marx, D. L. Boykin

Department of Agronomy and Horticulture: Faculty Publications

Early generation selection experiments typically involve several hundred to thousands of lines. Various systematic and statistical techniques have been developed to increase effectiveness and efficiencies in such experiments, including the development and application of spatial statistical models. In this study, mixed model equations were used to provide least squares means (LSMEANs) and best linear unbiased predictors (BLUPs) and compare selection effectiveness and efficiencies to observed (Y) and true values in simulated experiments varying in size (10 X 10, 20 X 20 and 30 X 30 grids), control plots densities (0, 5, 10, 20, and 50%), control plot arrangements (high, medium, …

Development Of A Process Of Addition Of Tricalcium Phosphate From Burnt Phosphate Rock In Feed For Animal Nutrition, Luis Fernando Nogales Grágeda

Theses and Dissertations

This study took place in Bolivia with the purpose of using thermally treated Capinota phosphate rock as a phosphorous supplement in balanced feed diets. The objective was to produce a natural phosphate substance that would be more easily accessible to the local population than commercial feed supplements. An additional objective of this study was to increase the availability of the low-fluoride phosphorous. The biological assays indicated that the diet with the added burned phosphoric rock produced similar yields to those using a commercial feed supplement (dicalcium phosphate). This indicates that the locally manufactured product, by partial acidification, can compete with …
