New Yellow Serradella Varieties For Low Rainfall Pastures, Clinton Revell
New Yellow Serradella Varieties For Low Rainfall Pastures, Clinton Revell
Journal of the Department of Agriculture, Western Australia, Series 4
Large areas of acidic, sandy soils in Western Australia's low and medium rainfall, wheatsheep areas are suited to the pasture legume, yellow serradella.
In the past, a lack of varieties with suitable maturity has limited the use of this species.
New varieties developed in Western Australia and significantly earlier in maturity than traditional types can now extend the use of yellow serradella into these regions.
Taking The Emu To Market, Paul Frapple, Ruth Hagan
Taking The Emu To Market, Paul Frapple, Ruth Hagan
Journal of the Department of Agriculture, Western Australia, Series 4
Licensed, commercial emu farming in Western Australia is now five years old.
This year, 13,500 birds will be processed for their meat, skin and oil. Production has exceeded demand at prices which the industry considers fair because the industry is still developing marketd for these producys.
Without secure, long term markets, over-production will worsen as the turn-off in this State increases and emus become available from other Australian states and overseas.
The Department of Agriculture is assisting the industry to develop a viable industry.
Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin
Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin
Journal of the Department of Agriculture, Western Australia, Series 4
After years of severe drought, stocking rates in Western Australia s arid rangelands have been kept low since the 1970s to allow native pastures to regenerate. As well, extensive re-seeding programs have started and sheep and cattle grazing on these areas has been restricted or eliminated. However, pasture regeneration in the rangelands can only succeed when grazing by all animals - sheep, cattle, kangaroos, goo.ts, camels, brumbies and donkeys - is controlled Many more red kangaroos roam throughout Western Australia's pastoral areas today than 20 years ago. The installation of windmills and troughs to water domestic livestock has allowed kangaroo …

How To Reduce Spending On Land Conservation, Tim Negus
How To Reduce Spending On Land Conservation, Tim Negus
Journal of the Department of Agriculture, Western Australia, Series 4
Heavy spending on capital works for land conseroation is usually out of the question in the present financial climate, but the recession does not mean that landcare must be abandoned. There are many aspects of landcare that involve little or no extra cost. Soil conseroationist Tim Negus discusses them in this article.

Groundwater Investigations In The Jerramungup Shire, S B. Martin
Groundwater Investigations In The Jerramungup Shire, S B. Martin
Resource management technical reports
Drilling was carried out with a dry rotary auger rig, with a depth limit of 31 m for the first 28 piezometers and 40 m thereafter. Farmers assisted in the site selection and construction of the piezometers in most cases and will in the future be responsible for monitoring their piezometer(s) regularly. The average depth to bedrock was 18 m and the average dept to groundwater was 9 m, with an average salinity level of 3600 mS/m. The average total salt storage was approximately 2800 tonnes per hectare.

Land Resources Of The Kellerberrin Region, William Morrison Mcarthur
Resource management technical reports
The landforms and associated soils in the Kellerberrin area (Figure 1) were mapped using a combination of air photo interpretation (1:50,000 black and white, 1984 photography) and ground traverses along roads and tracks. Mapping units used are similar to those described by Bettenay and Hingston (1961; 1964) and Hingston and Bettenay (1961) for the Merredin district. The present survey may be seen as a western extension of the Merredin survey; it adjoins the work of Lantzke (in prep) on the west
The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
Journal of the Department of Agriculture, Western Australia, Series 4
Earthworms have a reputation as soil builders and renovators, particularly among 'organic' farmers and gardeners. They improve soil fertility through increased aeration, aggregation, water infiltration and release of nutrients from organic matter. However, the benefits of earthworms in the wheatbelt have been doubted for many years because of their poor survival in cultivated soils.
Since cropping began in the Western Auslmlian whealbelt over 1OO years ago, the physical condition of many soils has deteriorated. The primary causes of soil degradation were the European cultivation practices used by farmers and the trampling effect of introduced animals. in particular, sheep.
Reasons For The Underrepresentation Of Females At Head Of Department Level In Physical Education In Government Secondary Schools In Western Australia: Perceptions Of Female Physical Education Teachers, Regina D. Bloot
Theses: Doctorates and Masters
This study focuses on reasons why so few females hold Head of Department positions in physical education in government secondary schools in Western Australia. Despite the almost equitable proportion of females and males teaching the subject, and the absence of Ministry of Education policy constraints on female promotion since 1972, females remain grossly underrepresented in leadership roles. In 1991, women held only five (7%) of the 70 substantive Head of Department appointments. Individual indepth interviews were used as the means of data collection to document female teachers' own accounts of their lives, career aspirations, and what they perceived to be …
Secondary Non-Art Teachers' Perceptions Of Characteristics Of An Effective Art Teacher, Christine M. Morton-Lo
Secondary Non-Art Teachers' Perceptions Of Characteristics Of An Effective Art Teacher, Christine M. Morton-Lo
Theses : Honours
Since 1986, the offering of art in secondary schools as a Tertiary Entrance Examination subject has secured its position as a school subject. However, there is increasing pressure on art and on other subjects offered in secondary schools in Western Australia, to demonstrate a contribution to Australia's social, economic and cultural priorities. In an increasingly competitive educational environment, all subjects need to negotiate viable positions as courses of study. As a result of the implementation of the Better Schools Report 1987, school-based decision-making groups have been established to assume responsibility for matters which had previously been the concern of a …
A Gender Analysis Of Teacher Feedback In Coeducational Secondary Physical Education Lessons, Paul R. Watson
A Gender Analysis Of Teacher Feedback In Coeducational Secondary Physical Education Lessons, Paul R. Watson
Theses : Honours
The purpose of this study was to examine whether the verbal feedback distribution patterns of teachers in coeducational secondary physical education lessons were gender equitable. Previous literature indicated that inequality in verbal interaction and feedback existed in coeducational secondary physical education classes. This inequality tended to favour males to the disadvantage of females.
Fourteen lessons by male teachers and fourteen lessons by female teachers were video-recorded. The study utilized a modification of the systematic behaviour observation instrument developed by Siedentop (1983). Data obtained were categorized for analysis and interpretation. Statistical procedures were applied to establish the significance of the findings. …

Revegetation Guide To The Central Wheatbelt, E C. Lefroy, R J. Hobbs, L J. Atkins, Department Of Agriculture And Food, Western Australia, Csiro, Division Of Wildlife And Ecology
Bulletins 4000 -
The rapid development of the central wheatbelt for agriculture over the past century has produced a productive farming landscape, but one which is increasingly subject to degradation. Erosion, salinization, declining soil structure, waterlogging and acidification are all symptoms of this degradation and causes of lost agricultural production. In addition, most of the native vegetation and many of the native animals have disappeared, and the natural heritage of the area resides in small scattered patches that together make up only seven per cent of the wheatbelt region.
Many farmers now recognize that replanting trees and shrubs is an effective means of …

Selecting And Developing Reliable Bore Sites In The Eastern Wheatbelt, Richard George
Selecting And Developing Reliable Bore Sites In The Eastern Wheatbelt, Richard George
Bulletins 4000 -
In the Western Australian wheatbelt, groundwater supplies contribute about 40 per cent of the on-farm livestock requirements and occasionally domestic water supply systems. The first part of this Bulletin comments on sites suitable for both high yielding bores and also those which yield water suitable for livestock. The second part outlines techniques for constructing and developing a bore. Throughout this Bulletin livestock quality water, for adult sheep, is defined as groundwater of less than 12,000 mg/L (or 850 grains per gallon) which has not been subject to localized pollution. For other livestock, the maximum salinities range from 2,600 mg/L for …

Miscellaneous Publication 17/91 - Mudas - Model Of An Uncertain Dryland Agricultural System: A Description, R. S. Kingwell, A. D. Bathgate
Farm Systems and Economics research reports
In the early 1980s, the Department of Agriculture developed a mixed integer whole-farm mathematical programming model of the dryland farming system in the eastern wheatbelt of Western Australia (Morrison et al. 1986). The model named MIDAS (Model of an Integrated Dryland Agricultural System) was constructed, tested and scrutinised by a multi-disciplinary team of researchers, advisers, farm management consultants and farmers (Kingwell 1987a). The model described in some detail the biology and finances of the dryland farming system in an average season and calculated profit-maximising farm plans.
MIDAS remains an often used tool in research and extension, being applied to many …

Tackling Salinity On The Esperance Sandplain, S J. Hearn, National Soil Conservation Program (Australia)
Resource management technical reports
The Esperance sandplain has serious secondary salinity. Waterlogging and poor surface drainage compound the problems. The original aim of the project was to promote high water use pastures for areas of deep sands as a way of limiting rechrge to the saline groundwater. This aim was later broadened to include the promotion of deep-rooted perennial pastures on all suitable soils.

Fisheries Research Report No 91 - A Synopsis Of The Biology And The Exploitation Of The Australasian Pilchard, Sardinops Neopilchardus (Steindachner) Part Ii: History Of Stock Assessment And Exploitation, W. J. Fletcher
Fisheries Research Reports
This report summarises the studies which have provided information on the population characteristics and exploitation of the pilchard, Sardinops neopilchardus in Australia and New Zealand. This review was undertaken to determine whether existing data could be used to assess the status of Western Australian or other stocks or, alternatively, what additional information was required.
The mean size of pilchards caught varies among locations but, in general, fish are between 140 and 160 mm LCF, corresponding to ages 2 - 5 years. The length-weight relationship also varies between locations
Attempts to initiate pilchard fisheries have been hampered by the lack of …

The Mallee Road Catchment Project, Rachel Siewert, S Abbott, National Soil Conservation Program (Australia), R A. Nulsen
Resource management technical reports
The Mallee Road Sump catchment is a 30,000 ha catchment located immediately south of a major drainage divide in the central southern agricultural region of Western Australia. The catchment has been largely developed for agriculture over the last 25 years and is now showing development of secondary land salinization. Agronomic trials have shown that it is possible to considerably increase plant production in the area and simultaneously reduce recharge to the groundwaters.
