Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis Dec 1993

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis

Natural resources published reports

It is now some 33 years since the Ord River Regeneration Project, the largest and most ambitious of its kind in Australian rangelands, commenced.

During this time there have been a number of publications and miscellaneous reports about the project, but this publication is by far the most comprehensive produced to date. Although the field work was undertaken in 1981, the findings recorded here will stand in a good stead as a detailed account and reference work for years to come.

Much has changed within the Regeneration Reserve area since the project commenced. Cattle and feral donkey numbers have finally …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George Jan 1993

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …


The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen Jan 1993

The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen

Masters Theses

A 150kg lawn roller was used in combination with various Plant Growth Regulators (PGR) (Embark & Event, Event & Oust, Embark & Oust, Escort & Oust, Telar & Oust, Event & Balan, Oust & Balan, and Balan) to evaluate its affects on the growth rate of rough turf at the Coles County Airport. The rolled plots were evaluated for height, reduction of seedheads, phytotoxicity, and weed control. Rolling was of no significance to treated or untreated turf. PGR combinations containing Oust were significantly better at reducing turf height than combinations lacking Oust. PGR combinations lacking Oust discolored turf significantly less …

Visions For Agriculture, Department Of Agriculture, Western Australia

Agriculture reports

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Distribution And Ecological Significance Of On-Farm Bushland Remnants In The Southern Wheatbelt Region Of Western Australia, F Mollemans, G Beeston Jul 1992

Distribution And Ecological Significance Of On-Farm Bushland Remnants In The Southern Wheatbelt Region Of Western Australia, F Mollemans, G Beeston

Soil conservation survey collection

The Southern Wheatbelt Region Remnant Vegetation Survey was funded by the Save the Bush program, and aimed at surveying pieces of on-farm remnant vegetation in the "Great Southern" of Western Australia. At the outset a total of 13 shires were selected for survey, namely: Broomehill, Corrigin, Dumbleyung, Katanning, Kent, Kondinin, Kulin, Lake Grace, Narrogin, Tambellup, Wagin, Wickepin, Woodanilling. However, time constraints (available funding indicated a time frame of 40 weeks for the project to be completed) meant that subsequently Kent and Lake Grace shires (two of the largest) had to be dropped from the survey to allow for proper completion …

Responses Of Canada Thistle To Defoliation And To Damage From A Stem-Mining Weevil In Utah, Wendy Sue Halsey May 1992

Responses Of Canada Thistle To Defoliation And To Damage From A Stem-Mining Weevil In Utah, Wendy Sue Halsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The responses of Canada thistle stems to damage by two types of herbivores were investigated to determine the potential role of these herbivores as biological control agents. Canada thistle stems at a cattle exclosure in Rich County, Utah were cut at one to two centimeters aboveground in June, 1991, to mimic grazing by cattle. Neighboring stems within 30 centimeters were also cut in some treatments to investigate the effects of physiologically connected ramets on the growth and reproductive responses of individual focal stems. I measured plant height, stem diameter, and number of flowerheads for each of the focal stems during …

Herbicide Trials On Field Crops 1991, Robert Frans, Marilyn Mcclelland, David Jordan

Arkansas Agricultural Experiment Station Research Series

Herbicidal weed control is economically important for production of field crops. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental ancommercial herbicides for selective control of weeds in several important crops. These experiments serve both industry and Arkansas agriculture by providing information on the selectivity of herbicides still in the developmental stage and by comparing the activity of these new herbicides with that of recommended herbicides.

It is just as important that both the sprayer and the way it is used allows you to meet this objective. This Bulletin will help you select the right boom sprayer, maintain it for efficient operation and use it efficiently and safely.


Managing Brome Grass In The Wheat:Lupin Rotation, Aik Hock Cheam, Gurget Gil, Christine Zaicou Jan 1992

Managing Brome Grass In The Wheat:Lupin Rotation, Aik Hock Cheam, Gurget Gil, Christine Zaicou

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

Some farmers and scientists are questioning the sustainability of the cereal:lupin rotation in the Western Australian wheatbelt.

Being a 'tight' rotation, its continuation is constantly under threat by disease, especially lupin root rots caused by Pleiochaeta (the brown spot organism) and Rhizoctonia fungi. To control disease, some farmers have lengthened the rotation to three years, such as wheat:wheat:lupins or wheat:barley:lupins. The longer cereal phase also helps to stabilise soil against wind erosion. However, such rotations can lead to a rapid buildup of brome grass during the two consecutive years of cereals. The implications of these rotations on the severity of …


Paddock Sampling For Management Of Annual Ryegrass Toxicity, Ian Riley Jan 1992

Paddock Sampling For Management Of Annual Ryegrass Toxicity, Ian Riley

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

Annual ryegrass (Lolium rigidumJ seedheads containing corynetoxins, a group of bacterially produced antibiotics, are poisonous to livestock. Animals that eat affected ryegrass develop annual ryegrass toxicity (ARGT), suffer convulsive staggers and die within a few days of eating a lethal dose. ARGT is characterised by high death rates, especially where pastures are not known to be affected and where stock-owners are not expecting the problem. Fortunately, there are commercial tests that determine the levels of ARGT organisms in the paddock and the risk of getting the disease. These tests will help farmers plan their cropping and pasture programs for the …


New Leaf Rust Helps To Control Blackberry, Jonathon Dodd, Sandy Lloyd Jan 1992

New Leaf Rust Helps To Control Blackberry, Jonathon Dodd, Sandy Lloyd

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

The release of spores of the blackbeny leaf rust in spring 1991 marked the second attempt in Western Australia at controlling weedy blackberries with a biological agent. The strain of rust now being used is expected to be more effective than the one released in the 1980s.

This article describes the techniques used for rearing and releasing the fungus and illustrates the effects of the rust on blackbeny.

Navail Spreadsheet, S J. Burgess Jan 1992

Navail Spreadsheet, S J. Burgess

Agriculture reports

A computer program called NPDECIDE has been developed by the Western Australian Department of Agriculture to assist with decisions relating to the use of phosphorus fertiliser on cereal crops. NPDECIDE functions by estimating the response of the crop to combinations of nitrogen and phosphorus fertilisers, and by indicating the likely profit from the use of these materials. In order to carry out this task, NPDECIDE must be able to calculate the availability to the growing plants of nitrogen from the fertilisers and from organic material in the soil.

Using Goats To Control Weeds, John Peirce Jan 1991

Using Goats To Control Weeds, John Peirce

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

Feral goats are common in the woodland and tall shrubland areas of arid Australia. They survive and reproduce despite regular shooting, capture and droughts. These goats are considered vermin in Western Australia because of their competition with sheep for forage and their reputation as destroyers of vegetation. Research elsewhere, however, has indicated that it is only the uncontrolled grazing by large numbers of goats that causes degradation, in the same way that uncontrolled grazing by sheep can cause erosion. To some people, however, feral goats are a valuable source of income. They have the potential for meat sales, and they …
