The Potential For Avocados In Western Australia, Michael Gregory Hawson
The Potential For Avocados In Western Australia, Michael Gregory Hawson
Journal of the Department of Agriculture, Western Australia, Series 4
"The flesh of the ripe fruit is ivory yellow, framed in a surround of exquisite green"
There is only one fruit to which this comment can apply and that is the avocado.
While now regarded as a luxury, avocados have met ready demand on major markets indicating that limited expansion of avocado growing in Victoria, South Australia and Western Australiacouldmprovide quite profitable returns.
Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.
Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.
Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.
Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.

Tincurrin : A New Biscuit Wheat, J T. Reeves, H. M. Fisher, G. B. Crosbie
Journal of the Department of Agriculture, Western Australia, Series 4
Although a demand has existed both locally and overseas for soft wheat suitable for biscuits, cakes and various confectioneries, production has been very limited.
In 1978 farmers in the soft wheat area will be able to grow the higher yielding variety Tincurrin.
It is recommended for general sowing to replace all varieties grown at present in the soft wheat areas as defined.Exceptions may prevail in areas prone to rust snd septoria problems.
Rejections Of Sheep And Lamb Carcasses Are Costly, R H. Wroth, R. J. Suiter
Rejections Of Sheep And Lamb Carcasses Are Costly, R H. Wroth, R. J. Suiter
Journal of the Department of Agriculture, Western Australia, Series 4
A 1976 survey of more than 48 000 sheep and 25 000 lambs slaughtered at two of Western Australia's export abattoirs has indicated a high rejection rate for W.A. carcasses. Rejections may be for disfiguring, blemishes requiring trimming or for diseases which can lead to condemnation.
Savings that producers can make by simple management changes, could thus save the industry $3.12 million a year. Reduction in other causes of rejection or further reduction in some of those mentioned id feasible but requires more research and may be more difficult to achieve.
Stonefruits Have A Future, Geoffrey L. Godley
Stonefruits Have A Future, Geoffrey L. Godley
Journal of the Department of Agriculture, Western Australia, Series 4
Over the 10 year period from 1966/67 to 1975/76, stonefruit production has not greatly expanded. The area planted has declined and the number of young, non-bearing trees also has declined.
Trends in the price ofsdtonefriut for the past decsde have revealed no real improvement on local or export markets but it is unlikely that these trends will continue. While costs will continue to rise, profitability of stonefruit is likely to be helped by cost saving techniques. Mechanical equipment changes and changes to management techniques will mean reduced management costs.
Potassium Deficiency In Lupins : Identification, Rates, Times And Method Of Application, Walter Jacob Cox
Potassium Deficiency In Lupins : Identification, Rates, Times And Method Of Application, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Large areas of sandplain soils north of Perth are low in potassium levels, and responses to applied potassium have been large for both sub. clover and grain lupins.
This article indicates where potassium might be needed, and how to diagnose and overcome deficiencies in lupins.
The Autumn Feed Problem In Beef Cattle Management, D J. Barker, P. J. May
The Autumn Feed Problem In Beef Cattle Management, D J. Barker, P. J. May
Journal of the Department of Agriculture, Western Australia, Series 4
In south-western Australia all grazing stock face a period of 'inadequate' nutrition each autumn.
The Department of Agriculture's beef production research programme has for some years sought solutions to this problem, and the results from the programme have been used to develop strategies for achieving satisfactory production levels at least cost during autumn.
This article discusses the resulting techniques, and the research on which they are based.
Farm Syndication Has Advantages, G T. Kennedy
Farm Syndication Has Advantages, G T. Kennedy
Journal of the Department of Agriculture, Western Australia, Series 4
Sharing of single items of plant between farmers is common in Australian Agriculture but it is quite rare for farmers to amalgamate their holdings and farm them as a single unit.
This article looks at the advantages of syndicate farming. It is based on a study of four whole farm syndicates in the Wimmera of Victoria.
Wesreo : A Blackleg Resistant Rapeseed, N N. Roy
Wesreo : A Blackleg Resistant Rapeseed, N N. Roy
Journal of the Department of Agriculture, Western Australia, Series 4
A new rapeseed variety, Wesreo, has recently been released after an unusually rapid and successful breeding programme by the Department of Agriculture.
Wesreo has fairly good resistance to the disease blackleg, which virtually halted the expanding rapeseed industry in 1973.
Trials Indicate Best Lupin Seeding Rates, G H. Walton
Trials Indicate Best Lupin Seeding Rates, G H. Walton
Journal of the Department of Agriculture, Western Australia, Series 4
Trials on the seeding rate of lupins have shown that for most crops, at least 80kg of seed per hectare gives best yields. However the yields varied considerably, and in higher yielding situations, lower seeding rates were better.
Apple Orchards To Take A New Look, J E L Cripps
Apple Orchards To Take A New Look, J E L Cripps
Journal of the Department of Agriculture, Western Australia, Series 4
Results of experiments by the Department of agriculture could completely change the appearance of the apple orchard in the next decade.
The normal orchard scene will become hedgerows of chemically-thinned, irrigated, red varieties on dwarfing or semi-dwarfing rootstocks receiving just the right amount of fertiliser, and areas between rows will be mown, or sprayed with herbicide. The clean cultivated, square-planted, vase-shaped tree will slowly disappear.

Progress In Clover Scorch Research, A Bokor, D. L. Chatel, D. A. Nicholas
Progress In Clover Scorch Research, A Bokor, D. L. Chatel, D. A. Nicholas
Journal of the Department of Agriculture, Western Australia, Series 4
Considerable progress has been made with the clover scorch problem since the devastation of the 971 epidemic when intensive research began.
Over 2000 varieties and crossbreds of subterranean clover from various collections have been screened for resistance resulting in the release of the first resistant clover, Esperance, this year.
Benefits of fungicidal spraying have been demonstrated and low cost spraying programmes for grazed pastures, and seed and hay crops are under field investigation.

Seed yields of early maturing subterranean clovers. A brief description of weather conditions in 1977, site details and results of germination counts and growth ratings were included in the Summary Report for 1977. Drill-sown trials - Seed yields from the trials varied from good in the southern wheatbelt to very poor in the northern areas. Test samples were taken from trials 77GE32, 77GE40 and 77GE41 in the Pindar and Tardun districts, 77ME22 at Koorda and 77TS25 at Perenjori but the quantity of seed did not warrant yield assessment. Trial 77M022 at Gabalong was not sampled. Seed yields from the rest …
