Bulletin 4371 - Growing Bamboo In Western Australia, Bob Gretton, John Burt

Bulletins 4000 -

Bamboo belongs to the subfamily Bambusoidae, a tribe of the Poaceae or grass family. They include 45 genera and over 1000 species. Many bamboo have edible shoots. The culms (stems) are fast growing, strong, light and useful as timber. These characteristics make the bamboo family valuable plants.

In Australia, there has been increasing interest in growing bamboo since the International Bamboo Congress in Bali in 1995. The principal driving forces of this new industry are edible shoot production and timber production. A Bamboo Growers Seminar was held in Brisbane in 1997. A Bamboo Growers Association for Australia was formed in …

Farming Exotic Mushrooms In The Forest, Deborah B. Hill

Agroforestry Notes (USDA-NAC)

One income opportunity derived from forest farming is the production of exotic mushrooms. Many of these edible mushrooms, such as shiitake (Lentinula edodes), maitake (Grifola frondosa), lion's mane (Hericium erinaceus, and oyster (Pleurotus spp. feed on the cellulose and lignin in wood. Although a significant volume of these mushrooms is produced under artificial conditions on a substance of sawdust, grains and other supplements, production on logs results in firmer texture and more flavor.

Production of high-value mushrooms on small diameter logs of almost any hardwood species enables a private forest landowner to utilize …

Forest Production Of Goldenseal, Jeanine M. Davis

Agroforestry Notes (USDA-NAC)

Goldenseal (Hydrastis canadensis L.) is a valued medicinal herb which has been collected from hardwood forests in eastern North America for hundreds of years. The historical range for goldenseal is north into Canada, south to Alabama, and west to Kansas. Overharvesting of goldenseal has caused serious reductions in populations reported in Illinois, Ohio, Indiana, and eastern Kentucky. In 1997, goldenseal was listed on Appendix II of the Convention for International Trade on Endangered Species (CITES), an international treaty monitoring trade in threatened and endangered species. Designed to protect the species, this listing imposed controls on goldenseal trade. This …

Economics And Marketing Of Ginseng, Robert L. Beyfuss

Agroforestry Notes (USDA-NAC)

It is extremely important to learn about the economic potential of the various types of ginseng and how to market the product prior to growing it. Raising ginseng is something that a patient person who enjoys growing things can find interesting and potentially profitable but, it requires hard work, at least a small capital investment, and it certainly is not a sure thing. This Agroforestry Note will familiarize readers with some economic considerations and marketing tips. For specific information about growing ginseng refer to AF Note Forest Farming -3, American Ginseng Production in Woodlots.

Miscellaneous Publication 37/99 - Codes Of Practice For Vegetable Production On The Swan Coastal Plan, N. Lantzke, A. Galati

Field Evaluation Of Herbicides On Small Fruit, Vegetable, And Ornamental Crops, 1998, Ron E. Talbert, Lance A. Schmidt, Jennifer A. Wells

Arkansas Agricultural Experiment Station Research Series

Growers generally use herbicides to efficiently produce high-quality fruit and vegetables for processing or fresh market sales. Due to the smaller acreage of these crops compared to major field crops, fewer herbicides are registered for use in fruit and vegetable crops than for field crops. Each year, new herbicides are evaluated under Arkansas growing conditions with the objective of improving the herbicide technology for the grower, processor, and ultimately the consumer. This report includes studies on the control of many of the more serious weed problems in important crops of this region, including snapbeans, spinach, southernpeas, watermelon, cantaloupe, summer squash, …

Cereal Rust Diseases And Their Management, 1999, Rob Dickie, Rob Loughman, Jat Bhathal

Technical Bulletins

• Wheat leaf rust (Puccinia recondita f.sp. tritici) is specific to wheat and triticale. A single pathotype (designated 104-1,2,3,(6),(7),11) has dominated in W.A. since 1990. Wheat leaf rust regularly survives the non-cropping summer in varying quantities, usually sufficient to occur at least to a limited extent (particularly in southern regions) each year. The disease develops rapidly between 15 and 22°C when moisture (including dew) is non-limiting. The highest yield increase attributed directly to control of leaf rust in W.A. is 37 per cent. However the disease is synergistically damaging in combination with septoria leaf blotches. In Esperance in …

Identification Of Quantitative Trait Loci Affecting Female Reproductive Traits In A Multigeneration Meishan-White Composite Swine Population, G. A. Rohrer, J. J. Ford, T. H. Wise, J. L. Vallet, R. K. Christenson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A multigeneration crossbred Meishan- White composite resource population was used to identify quantitative trait loci (QTL) for age at first estrus (AP) and the components of litter size: ovulation rate (OR; number of ova released in an estrous period) and uterine capacity (UC). The population was established by reciprocally mating Meishan (ME) and White composite (WC) pigs. Resultant F1 females were mated to either ME or WC boars to produce backcross progeny (BC) of either ¾ WC ¼ ME or ¼ WC ¾ ME. To produce the next generation (F₃) , ¾ WC ¼ ME animals were mated …

Bulletin 4359 - Soils Of The Swan Coastal Plain, Mike Bolland

Bulletins 4000 -

Almost all the soils of the Swan coastal plain are formed by material deposited by sea, rivers and wind. The Yilgarn Block, east and south of the Scarp bordering the Swan Coastal Plain (Fig. 1), rose about 40 to 50 million years ago. This caused erosion of the block by rivers and streams, and the eroded material was either deposited onto the Swan Coastal Plain or washed into the sea. The eroded material formed new soils on the Plain.

Broadly there are two major types of soils on the Coastal Plain. The first is a series of dune system near …

Real-Time Monitoring Of Escherichia Coli O157:H7 Adherence To Beef Carcass Surface Tissues With A Bioluminescent Reporter, Gregory R. Siragusa, Kevin Nawotka, Stanley D. Spilman, Pamela R. Contag, Christopher H. Contag

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A method for studying bacteria that are attached to carcass surfaces would eliminate the need for exogenous sampling and would facilitate understanding the interaction of potential human food-borne pathogens with food animal tissue surfaces. We describe such a method in which we used a bioluminescent reporter strain of Escherichia coli O157:H7 that was constructed by transformation with plasmid pCGLS1, an expression vector that contains a complete bacterial luciferase (lux) operon. Beef carcass surface tissues were inoculated with the bioluminescent strain, and adherent bacteria were visualized in real time by using a sensitive photon-counting camera to obtain in situ …

Arkansas Cotton Variety And Strain Tests 1998, Fred M. Bourland, G. M. Palmer, J. M. Hornbeck, C. D. Capps Jr.

Arkansas Agricultural Experiment Station Research Series

The primary aim of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties in the major cotton growing areas in Arkansas. This information helps seed dealers establish marketing strategies and assists producers in choosing varieties to plant. In this way the annual test facilitates the inclusion of new, improved genetic material into Arkansas cotton production. The 1998 test had 58 entries (including 19 transgenic genotypes and 21 first-year entries), which were evaluated at six sites in eastern Arkansas. The presence of four transgenic and five first-year entries among the top 10 yielding …

Bulletin 4357 - Fertilisers For Pastures On Sandy Soils Of The Swan Coastal Plain, K. W. Angell

Bulletins 4000 -

When newly cleared for agriculture, the sandy soils of the Swan Coastal Plain were acutely deficient in phosphorus (P), nitrogen (N), and the trace elements copper ( Cu) and zinc (Zn) and sometimes molybdenum (Mo). Phosphorus deficiency was overcome by applying single superphosphate. Trace element deficiencies were overcome by adding Cu, Zn and Mo to superphosphate during manufacture, allowing P, Cu, Zn and Mo to be applied to the pasture in the one operation.

It was subsequently found that low sulphur (S) and potassium (K) were limiting production and persistence of subterranean clover-based pastures on the sandy soils of the …

Intsormil 1999 Annual Report, John M. Yohe, Thomas Crawford Jr., Joan Frederick, Dorothy Stoner

INTSORMIL Impacts and Bulletins

Presently, worldwide, more than 800 million people do not get enough to eat or have access to a balanced diet to be healthy. At the World Food Summit in 1996, the United States of America (USA) and 185 other countries pledged to reduce the number of malnourished people by one half by 2015. It is shocking that about 33% of preschool children in developing countries will be stunted due to malnutrition by the year 2000. The number of stunted children in Africa alone has increased significantly from 35 million in 1980 to 45 million in 1995 and is predicted to …

A Snapshot Of Horticulture Western Australia, Department Of Agriculture, Western Australia

Horticulture published reports

Western Australia's horticultural industry is one of 'the fastest growing primary production sectors. Gross value of production in 1996/97 was $383 million dollars according to Australian Bureau of Statistics data. However, we know that these data underestimate the value of the industry by about 12 per cent for the fruit sector and by over 50 per cent for the vegetable sector. The true GVP is closer to $500 million.

Good quality land and water resources in areas suitable for horticultural production are available for industry expansion. Some of the traditional enterprises on the irrigable land in the south-west are becoming …

Alley Cropping: An Agroforestry Practice, Sandra Hodge, H. E. Garrett, Jerry Bratton

Agroforestry Notes (USDA-NAC)

Alley cropping is an agroforestry practice intended to place trees within agricultural cropland systems. The purpose is to enhance or add income diversity (both long and short range), reduce wind and water erosion, improve crop production, improve utilization of nutrients, improve wildlife habitat or aesthetics, and/or convert cropland to forest. The practice is especially attractive to landowners wishing to add economic stability to their farming system while protecting soil from erosion, water from contamination, and improving wildlife habitat.

Bulletin 4387 - Women In Agriculture In Western Australia 1999, Agriculture Western Australia

Bulletins 4000 -

WESTERN Australian women in agriculture contribute huge economic, social and community benefits to industry, to the rural sector, and to the State overall. That this contribution is not fully acknowledged, is perhaps due to the lack of clear data; many economic or social measures do not disaggregate data by gender, despite women's and men's roles being very different. Other measures are based on outdated assumptions about how work is done, and by whom.

Department of Agronomy and Horticulture: Faculty Publications

A new method of determining in vitro dry matter digestibility (IVDMD) as recently developed in which the digestion is conducted with the forage samples in filter bags. Our objective was to compare the filter bag and conventional IVDMD analysis methods using smooth bromegrass (Bromus inermis Leyss.), switchgrass (Panicum virgatum L.), and forage sorghum [Sorghum bicolor (L.) Moench] samples. In addition, the filter bag analysis systems for determining non-sequential neutral and acid detergent fiber (NDF and ADF), respectively, were compared with the non-sequential conventional analysis systems. In the filter bag systems, the forage samples are sealed in filter bags and the …

Weed Management: Implications Of Herbicide Resistant Crops, Stephen Duke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Crops made resistant to herbicides by biotechnology are being widely adopted in North America and entering other parts of the world. Those containing transgenes that impart resistance to post-emergence, non-selective herbicides such as glyphosate and glufosinate will have the major impact. These products allow the farmer to more effectively use reduced- or no-tillage cultural practices, eliminate use of some of the more environmentally suspect herbicides, and use fewer herbicides to manage nearly the entire spectrum of weed species. In some cases, non-selective herbicides used with herbicide resistant crops reduce plant pathogen problems because of the chemicals’ toxicity to certain microbes. …

Runoff And Erosion From Interrill Areas As Affected By The Application Of Manure, John E. Gilley, Bahman Eghball, Jurg M. Blumenthal, David D. Baltensperger

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This study was conducted to measure runoff and erosion from interrill areas as affected by the long-term application of manure and fertilizer to a Tripp sandy loam soil located near Mitchell, Nebraska. Soil which had been removed from the top 0.1 m of the soil profile was placed in a 1 m² soil pan. Rainfall was then applied to the soil pan during initial and wet simulation events. Total runoff was similar on the manure and no-manure treatments. The long-term application of manure (55 years) at a rate of 27 Mg ha^-1 (wet basis) per year did not …

Relationship Between Spectral Data From An Aerial Image And Soil Organic Matter And Phosphorus Levels, Gary E. Varvel, Michael R. Schlemmer, James S. Schepers

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Early ventures into site-specific management involved fertilizer management decisions based on soil chemical properties characterized by some form of grid sampling. This is both labor and capital intensive and practitioners quickly began investigating other methods to get a measure of spatial variability. Aerial photographs, which were mainly used to evaluate and assess crop status, allow for the collection of whole-field data at relatively low cost. Our objective is to determine what relationships exist between aerial spectral data and intensive grid soil test results and whether this information can be used to improve future soil sampling strategies. Soil-test organic matter (OM) …
