Soybeans grown in Tennessee average about 20 percent oil and 40 percent protein. Soybeans are an important crop in Tennessee and rank in the top three for cash receipts for row crops each year. Soybean acres harvested for the last five years have ranged from 950,000 …

Chemical Composition And Quality Changes Occurring In Dioscorea Dumetorum Pax Tubers After Harvest, Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh

Professor Emmanuel Ohene Afoakwa

Studies were conducted on the chemical composition, as well as the biochemical and textural changes, occurring during storage of two cultivars of Dioscorea dumetorum yam tubers. The tubers were harvested and stored under tropical ambient (28_C) and cold room conditions (4_C) for 24, 48 and 72 h. The samples were evaluated for moisture, starch, sugars, fibres and textural properties. Chemical analysis showed no significant differences between the means obtained for moisture, ash, protein, fibre, fat, carbohydrate, calcium, phosphorus, iron, vitamin A and vitamin C contents of the cultivars (white and yellow) studied. During storage, moisture contents decreased by approximately 6–10% …

Profitable Canola Production In The Great Southern And Lakes District, Paul Carmody, Ashley Herbert

Bulletins 4000 -

The Canola industry has rapidly grown with a 10 fold increase in area sown in Western Australia over the four years from 1996-99.

The driving force behind this increase in area can be attributed to the successful adoption of weed control technology in Triazine Tolerant Canola.

By knowing the model of the limiting factors, which are usually; weed control, fertiliser practices, blackleg management, variety selection, seeding dates, seeding depths, insect control and swathing, we can make the right decisions and achieve the targeted profit.

To produce yield to potential, all factors need to be optimised, otherwise yields will be decreased …

Profitable Canola Production In The Northern Grainbelt Of Western Australia 2001, Paul Carmody, Adrian Cox

Bulletins 4000 -

Canola is a member of the Brassicaceae family that also includes mustard, turnip, wild radish, cauliflower, cabbage and broccoli.

It is a winter growing oilseed that can be produced in most arable areas of Australia where winter crops are currently grown. Originally known as rapeseed using the varieties B. campestris, the varieties of B. napus have almost completely replaced this earlier variety in all the areas where the crop is grown.

The swing to B. napus varieties was due to their superior yields, resistance to blackleg and better quality oil and meal. Canola can be grown on a wide variety …

Avocado Culture In Western Australia, Alec Mccarthy

Correlating Fissure Occurrence To Rice Quality For Various Drying And Tempering Treatments, Monica J. Jimenez, Terry J. Siebenmorgen, A. G. Cnossen

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

When a rice kernel fissures, it can break in subsequent food processing operations and lose its commercial value. Head rice yield (HRY) is a measure of the percent of kernels that remain whole (at least three-fourths of original length) after rice has been milled. Our experiment was designed to test the effect of a rapid state transition during drying and tempering processes using cultivars Bengal and Cypress. ‘Bengal’ is a medium-size kernel and ‘Cypress’ is a longsize, thinner grained cultivar. Immediately after drying, the rice samples were separated into four sub-samples and tempered for 0, 80, 160, or 240 minutes …

Prediction Of Rice Texture From Starch Profiles Measured Using High-Performance Liquid Chromatography, Hazel Fromm, J. F. Meullenet

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

Starch determines a large proportion of the textural properties of cooked rice. The amylose: amylopectin ratio plays a significant role in the functionality of native starch. In this study a medium-grain rice cultivar, ‘Bengal’, was used for starch structure characterization using high performance size-exclusion chromatography (HPSEC). This cultivar is characterized by having lower amylose content (15% to 20%) than long grain cultivars and being sticky when cooked, similar to short-grain cultivars. Rice samples were harvested in 1999 from five locations around Arkansas at state verification trials where cultural practices are closely monitored. Samples of this cultivar stored at a specified …

Intsormil 2001 Annual Report, John M. Yohe, Thomas Crawford Jr., Joan Frederick, Dorothy Stoner

INTSORMIL Impacts and Bulletins

Presently, worldwide, more than 800 million people are hungry and over one billion are desperately poor, and food demand is increasing rapidly. The majority of poor live in rural areas in developing countries and agricultural and food systems development is vital to economic growth; improving environmental quality; strengthening nutrition, health and child survival; improving the status of women; and promoting democratization. It is estimated that, between 1980 and 2030, the population ofow- and middle-income countries will more than double-to seven billion, compared with one billion for high-income countries. In the next 35 years, 2.5 billion people will be added to …

Arthropod Populations And Rice Yields In Direct-Seeded And Transplanted Lowland Rice In West Africa, I. O. Oyediran, E. A. Heinrichs

Department of Entomology: Faculty Publications

Two methods for planting rice in irrigated lowland were evaluated during the wet seasons of 1994 and 1995 to determine their effect on rice arthropod numbers, insect-caused rice plant damage, and rice grain yield. The six treatments tested were: hand transplanting of seedlings at spacings of 14 cm × 14 cm, 20 cm × 20 cm, and 30 cm × 30 cm; and direct-seeding of rice at 60 kg seeds ha^–1, 90 kg seeds ha^–1, and 120 kg seeds ha^–1. The most abundant arthropods in the study were the diopsid flies, Diopsis longicornis Maquart …

Zinc Fertilizer Rates And Mehlich Iii Soil Test Levels For Corn, Lloyd W. Murdock, Paula L. Howe

Agronomy Notes

Zinc (Zn) is the micronutrient most often deficient for corn in Kentucky. This problem occurs every year but is more commonly seen in years with a cool, wet spring. Although the environment, soil type and past erosion each have an effect, the most important factors controlling plant available Zn are the soil pH, extractable soil phosphorus (P) and extractable soil Zn. While the amount of Zn in the plant increases as the available soil Zn increases, increasing levels of soil P and pH are strongly associated with reduced levels of Zn in the plant.

Pb1667 Control Of Vole Damage In No-Till Soybeans, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Voles are a problem for farmers using minimum and no-till technologies for soybean production, because voles feed on soybeans from the time they are established until they are harvested. This problem is expected to increase as land enrolled in the Conservation Reserve Program (CRP) is returned to row crops. Retaining established cover through no-till farming decreases erosion, improves water quality, increases wildlife habitat and conserves moisture when compared to conventional tillage practices. However, voles that have established colonies and flourished beneath the cover established under CRP, crop residue or hay crops can devastate crop plantings. Significant stand reductions have been …

Evaluation Of Chilling Requirements For Six Arkansas Blackberry Cultivars Utilizing Stem Cuttings, Dayanee Yazzetti

Inquiry: The University of Arkansas Undergraduate Research Journal

Woody perennial plants including blackberries (Rubus subgenus Rubus Watson) require certain amounts of chilling or rest hours below 7T during the dormant season for successful bud break the following year. Blackberry cultivars developed in Arkansas are being grown in various climates worldwide, and all cultivars need chilling requirement estimates for accurate recommendations of adaptation. Determining chilling requirements using stem cuttings collected from field-grown plants rather than whole plants is a desirable system. We conducted a study to evaluate both artificial- and field-chilling of six cultivars. For the artificial-chilling study, 12-node stem cuttings were collected 2 days after the first killing …

Ecological Sustainability For Pastoral Management, Hugh Pringle, Ken Tinley

Journal of the Department of Agriculture, Western Australia, Series 4

Pastoralists and rangeland bureaucracies are now required to operate within the limits of ecological sustainability. However, while the concept of ecological sustainability has been enshrined in law and policy at State and Commonwealth levels in Australia, there has been little translation into pastoral management objectives. The introduction of the 'EMU (Ecosystem Management Unit) process', as an equal partnership between ecologists and pastoralists, promises to bring pastoralists into close dialogue with the landscapes they manage on their stations, and to acknowledge and manage for values other than pasture production. In doing so, pastoralists are likely to increase production, reduce costs, and …

Time and motion (TM) studies are useful in determining labor requirement to perform a specific task in manufacturing processes. These studies have been used in the dairy industry to evaluate the labor requirements for various tasks associated with milking routine and milk parlor. Data may be used to evaluate the impact of changes or help in understanding labor requirements. The objective of this project was to determine the labor requirements for removing manure from concrete basins prior to land applications.

Using Weather Stations in Nebraska Livestock Operations

Enforcement of environmental regulations placed on feedlots in Nebraska by the Environmental Protection Agency (EPA), have lead to an increased need for accurate documentation of weather variables. In addition to the need to monitor weather conditions for compliance, an accurate representation of current weather conditions within the microclimate of the livestock operation allow for proactive responses to periods of potential environmental stress periods (i.e. heat and cold stress). Currently, most producers use manual documentation of rainfall events, local weather forecasts and some degree of intuition to monitor weather conditions. Weather station technology exists …

How to Read a Manure Sample Report

Correctly sampling manure can be a challenge. Try to obtain a representative sample and get the sample to the lab as close as possible to the time when manure is going to be applied. It is preferable to obtain sample results before land application so that appropriate application rates can be determined.

Slurry samples should be taken at the time the slurry is being applied, so that you have a good mix of the manure storage. The amount of material is usually recorded in gallons per acre and once the analysis is received, …

This is part 1 of a two part series discussing the results of a manure marketing survey conducted by the University of Nebraska.
Livestock enterprises have undergone substantial structural change in recent years, including the concentration of livestock and poultry industry into fewer farms (Council for Agricultural Science and Technology, 1996). There has been a reduction in farms with cattle by 50% and farms with swine by 80% between 1965 and 1995 while numbers of hogs and cattle in inventory has stayed nearly constant (USDA, 1965-1995). Livestock and poultry produce, annually, 3.5 and 3.1 million tons of …
