Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest

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

Breeding new varieties of barley or other cereal crops usually takes between 12 and 15 years. five years of that time may be needed to stabalise the new varieties so that they breed trueto type, but anther culture can reduce this delay to only eight months. This technology will allow the Department of Agriculture's barley breeding programme to respond more rapidly to changes in goals set by industry and to meet market demands.

Alley Farming : New Vision For Western Australian Farmland, Ted Lefroy, Phil Scott

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

Alley farming is a system where crops and pastures are grown in the alleys between rows of trees and shrubs. The concept is new to Western Australia but one that is likely to become more familiar over the next few years. The objective is to use trees and shrubs to decrease the environmental side effects of agriculture, such as erosion and salinity while increasing farm profit through the direct and indirect value of the trees.

This article describes some examples of alley farming in Western Australia and discusses the challenge of getting the right tree species and layout to maximise …

Lupin Stubbles : Getting The Best With Weaner Sheep, Keith Croker, Colin Mcdonald, Jeremy Allen

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

Sweet lupins are now grown on about a million hectares in Western Australia each year. If half of the State's seven million weaners were grazed as recommended on half of the lupin stubbles, it could generate about $15 million from reduced supplementary feeding, greater wool production and other advantages. But correct management is important, particularly knowing when to take weaners out. Research by the Department over the last five years is now indicating how this should be done.

Direct Conversion Of Waste Paper To Valued Foodstuff: Growth Of The Oyster Mushroom (Pleurotus) On Old Newspaper, Elmer L. Schmidt

Journal of the Minnesota Academy of Science

Waste papers, such as newsprint not recycled for fiber recovery, may provide benefits such as production of valued mushrooms during their biological decomposition in low input simple technology systems. The edible gourmet mushroom Pleurotus ostreatus was grown on a newspaper substrate with small additions of spawn and wood chips. Prior sterilization of the paper was not required in successful outdoor incubation of inoculated bales. Heavy metal content of mushrooms from paper was similar to that found in commercial oyster mushrooms purchased at a local market

Southwest Research-Extension Center Field Day 1994

Kansas Agricultural Experiment Station Research Reports

Each Field Day report consists of individual research reports on topics specific to the region, including cultural methods for most of the major crops grown in Kansas, mitigating the effects of weeds, insects, and disease associated with those crops, and irrigation. Research is conducted and reports written by staff of the K-State Research and Extension Southwest Research Extension Center.

Holding Our Edge In Noodle Wheat, Graham Crosbie

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

For many years, the Japanese milling and noodle industries have regarded Australian Standard White (ASW) wheat from Western Australia as the best in the world for the manufacture of white, salted Japanese noodles known as 'udon' (pronounced oo-don).

Recently, the Australian Wheat Board has also developed a significant market for this wheat type in South Korea, where it has been readily accepted for the production of Korean dried noodles.

The Wheat Board has estimated the total market demand from Japan and South Korea for this type of wheat to be 1.0-1.2 million tonnes, equivalent to about 20-25 per cent of …

Distance Of Interference Of Red Rice (Orya Sativa) In Rice (O. Sativa), Sam L. Kwon, Roy J. Smith Jr., Ronald E. Talbert

Journal of the Arkansas Academy of Science

Three rice cultivars were grown to determine the distance at which red rice affects growth and grain yield. Red rice reduced grain yield of Lemont when rice plants grew within 71 and 53 cm of red rice in 1986 and 1988, respectively. Grain yield of Newbonnet was reduced when grown within 53 cm of red rice in both years. Grain yield of Tebonnet was reduced when grown within 53 and 36 cm of red rice in 1986 and 1988, respectively. Grain yield reduction in influenced areas averaged 35, 26 and 21% for Lemont, Newbonnet, and Tebonnet, respectively. As the distance …

New Medics Show Promise In The Northern Wheatbelt, Colin Mcdonald, Bradley Nutt

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

For more than 20 years Cyprus barrel medic has been the mainstay of pastures grown on the medium to heavy red clay loamss of Western Australia'slow rainfall wheatbelt. However, since the early1980s its resistance to aphids has declined followed by reduced productivitymand persistence.

Fortunately, a six year research program at Tenibdewa, near Mullewa, is on target to prove the superiority of Parabinga barrel medic and a mixture of Serena and Santiago burr medics. These varieties, which had not been widley tested in the region, generally out-perform Cyprus in all aspects because of their higher tolerance of aphids.

Tough Times Call For A Review Of Farm Business Performance, Martin Van Bueren, John Young

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

Most Australian farm businesses specialising in wool production are operating at a loss at current wool prices. After both short term operating and long term costs of capital depreciation are accounted for, only a small number of wool growers are able to make a profit with the wool market indicator below 500c/kg.

Poor prices have stimulated wool growers to review their operations and look to ways of improving cash flow in the short term, such as diversifying into cropping. The downturn should also prompt growers to address the longer term trends of declining terms of trade and historically poor productivity …

Crops In The Woolbelt : Current Options And Emerging Prospects, Wal Anderson, Ross Gilmour, Robyn Mclean, Peter Nelson, K H.M Siddique, Paul Carmody, Ian Prtichard

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

It has traditionally been more profitable to grow sheep for wool in the medium rainfall parts of the south-west of Western Australia than to grow crops . Crop production has been difficult owing to the hilly terrain, the frequency of waterlogging, the high incidence of damaging frosts in some areas, the frequency of losses from diseases, difficulties with wet weather at harvest, and a lack of adapted crop varieties.

Advances over the past decade have made cropping on a limited scale potentially profitable in the woo/belt.

This article is intended to bring the various options for crop production to the …

Bluegum Timberbelts For Profitable Landcare, Peter Eckersley

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

Revegetation with tasmanian bluegums in wide-spaced timberbelts appears to offer high returns, especially in areas where high winds cause crop and stock losses and where land can be saved from salinity and wwaterlogging.

In the South Coast and South-WestRegions, timberbelts will complement existing enterprises and so optimise overall land use. Graziers should be able to maintaine their stock numbers while creating an on-farm superannuation package.

The Department of Conservation and Land Management has been a major player in the development of bluegum timberbelts, but a few farmers are now adapting this concept to better suit their needs. Initial results are …
