Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin

Bulletins - 3000 - 3999

This article deals with those native, naturalized and cultivated plants, which by virtue of contained cyanogenetic glycosides, are known to be poisonous or potentially poisonous to livestock in Western Australia.

Cyanogenetic glycosides are chemical compounds which contain a cyanogen (cyanide) radical combined with a sugar molecule. The sugar moiety may differ in glycosides obtained from different plants, and as a consequence glycosides from different plants, containing different sugar moieties, may be given different names.

When a cyanogenetic glycoside is broken down by enzyme action, through injury to the plant or by microbial action in the digestive system of the animal, …

Bulletin 3992 - Nitrogenous Fertilisers For Cereal Production, M. G. Mason

Bulletins - 3000 - 3999

Because fertiliser prices continue to rise, it is becoming increasingly important to understand what affects the response to fertilisers by crops.

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, the farmer needs some understanding of how these factors work.

Effects Of Row Width And Seeding Rate On Yield And Other Agronomic Characteristics Of Three Soybean Cultivars, Russell Kithcart

Masters Theses & Specialist Projects

Soybeans have traditionally been grown in rows wide enough to allow mechanical cultivation and to increase lodging resistance. Improved cultivars and herbicides have permitted farmers to obtain yield advantages from narrower rows. The growth response of soybeans to variations in row width and seeding rates depends upon the cultivar and geographic location.

“Williams,” “Mitchell,” and “Essex” cultivars were planted at row widths of 18, 36, 54, and 72cm. at seeding rates of 33, 67, 100 and 134 kg/ha in multi-row plots. Data were collected from each plot for seed yield, lodging, plant height, height of lowest pod, seed and population …

IThe grasses comprise one of the world's largest families of flowering plants, with over 500 groups or genera containing well over 5000 individual types or species distributed throughout the world. About 125 groups have been recorded in Western Australia but it is probable that the list is far from complete. About one third of these have ° been introduced from overseas.

The purpose of this bulletin is to describe those grasses which are more commonly found in the south-west of Western Australia. Also, as many people are interested in knowing the name and nature of a grass when they find …

Evaluation Of Herbicides For Suppression Of Rhizome Growth From Johnsongrass (Sorghum Halepense L.) In Corn And Soybeans, John Oakes

Masters Theses & Specialist Projects

Johnsongrass (Sorghum halepense L.) presents a serious problem in the production of corn and soybeans in Kentucky.

Various rates of the thiocarbamates, dinitroanilines, carbamates, amides, ureas, and triazines were used in association with the crops corn (Zea mays L.) and soybeans (Glycine max L.) to determine the degree of suppression on rhizomatous johnsongrass infesting the previously named crops.

Suppression was determined by selecting areas within each treated plot, counting the number of culms, then harvesting johnsongrass rhizomes. Dry weights of rhizomes were then determined as a measure of rhizome suppression.

Results show that of …

Bulletin No 3863 - Plants Which Cause Kimberley Horse Disease, A. L. Payne

Bulletins - 3000 - 3999

Crotalaria crispata and Crotalaria retusa (Rattlepod), two plants responsible for Kimberley horse disease*, are, unfortunately, fairly widespread throughout the Kimberleys. Both species are apparently toxic in all stages of growth.

This bulletin is to assist pastoralists to:-

• Identify the two plants;

• Recognise the type of country and conditions under which they grow; and

• Locate horse paddocks on country where the plants are least likely to occur.

Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson

Bulletins - 3000 - 3999

Vitamin A is one of the essential vitamins for animal health. Grazing animals obtain their vitamin A requirements mostly from the carotene in green feed. This carotene is converted to Vitamin A in the intestinal wall and is passed to the liver and to a less extent the kidneys for storage. Some carotene also passes direct to the liver where it is stored before it is converted to vitamin A.

When dry pastures, hay and grains (except maize) are low in carotene content this ability of the animals to store vitamin A means that they usually have enough when there …

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg

Department of Agronomy and Horticulture: Faculty Publications

Most reports show good agreement between evapotranspiration (ET) rates estimated by Bowen Ratio-Energy Balance (BREB) method and rates measured with lysimeters, although underestimation by the BREB model has occasionally been reported. This study was conducted to evaluate the performance of the BREB technique in the climatic conditions characteristic of the central Great Plains, a region where a significant proportion of the energy consumed by evapotranspiration is supplied from advected sensible heat.

Agreement between the BREB method and lysimetric measurements of ET is good during non-advective periods but during advective periods the BREB model underestimates ET by about 20%. Data collected …

Yield And Chemical Composition Of Barley Silage, John Henry James

Masters Theses & Specialist Projects

The potential of Barsoy barley (Hordeum vulgare L.) as a silage crop was studied at Western Kentucky University in 1970-1971. The field study was conducted at two locations. Barley was seeded at the rate of 107.5 kg/ha in a Pembroke silt loam soil at both locations in September, 1970. At the time of planting the soil was fertilized with 7.5, 32.4 and 33.1 kg/ha of nitrogen, phosphorus, and potassium, respectively. Plants at location 2 received an additional 23.7 kg/ha of nitrogen in February, 1971.

Whole barley plants were harvested at weekly intervals from March 11 through June 3 at …

Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Fruit Growing In Western Australia, Western Australian Department Of Agriculture, Western Australian Tourist Development Authority

Horticulture published reports

Revised 1965.

The Mediterranean type climate of the coastal belt of the south-west of Western Australia is suitable for the commercial production of apples, pears, various stone fruits, oranges, grapes, and several other less important fruits. The warm dry summers (November-March), are too severe for the profitable production of many berry fruits and the winters too cool and wet for most tropical fruits. Figs, mulberries and olives all flourish in this climate but, for economic reasons, few are grown commercially.

A small tropical fruit industry, mainly bananas, has been established along the banks of the Gascoyne River at Carnarvon, which …
