Bulletin No 4146 - Commercial Production Of Pawpaws In Western Australia, J. R. Burt, B. L. Toohill

Bulletins 4000 -

The papaw (Carica papaya L.) is a native plant of Central America. It produces its highest yields of good quality fruit in tropical regions.

The tree is short-lived and rarely produces crops for more than two or three years. It is quick growing and soon reaches a maximum height of 5 to 7 m. It is usually unbranched, but may branch after either injury to the top or cutting back.

Land Capability And Land Use In The Leeuwin-Naturaliste Region, Peter John Tille, Neil Lantzke

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

The Leeuwin-Naturaliste region is one of Western Australia's most beautiful areas. Located in the far south-west corner of the State, it is a popular scenis and tourist spot, as well as supporting grazing, horticultureal and viticultural enterprises.

Outside of perth the region is the most popular tourist destination in the state. It is also responsible for about a quarter of the State's milk production, and 15 percent of the state's potato production and a quarter of the State's wine grapes.

Many new agricultural enterprises have opened up in the past 15 years, and the population has increased by almost 40 …

The Queensland Fruit Fly Eradication Campaign, G P. Ayling

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

Western Australia has started an extensive eradication campaign against the Queensland fruit fly, one of the worst horticultural pests in the world.

The programme, the largest of its kind in Australia, and one of the biggest in the world, involves the integration of three tequniques for fruit fly control: lure trapping, protien baiting and the release of sterile male flies.

Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher

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

Late last year the Mediteranean fruit fly (Ceratitis capitata Weidemann) was eradicated from Canarvon, Western Australia by using an intergrated programme of sterile insect releases and bait spraying.

The eradication marked the end of a four-year study on the use and effectiveness of the Sterile Insect Technique, a biological control technique which uses an insect pest against itself. such a study can be used as a basis for treating other threatening insect pests, such as the serious cattle pest screw-worm fly, should they be found in Asustralia.

Being a biological control method, the Sterile Insect Technique is an exellent …

Bulletin No 4077 - The Avocado In Western Australia, M. G. Hawson, Jacqui Davis

Bulletins 4000 -

The avocado, Persea americana, is a member of the laurel family, and a close relative of the common shade tree, camphor laurel. It is native to Mexico, Central America, West Indies and nearby areas where the fruit was often a major part of the diet of the Indians.

Avocado flesh contains good levels of protein, fat, phosphate, potash, thiamin, riboflavin and ascorbic acid and exceeds those in such fruits as apples, apricots and bananas.

The tree is an evergreen, although some varieties lose their leaves for a short time before flowering. The canopy of varieties such as Fuerte, Rincon and …

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.

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.

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.

The Banana Industry At Carnarvon, John Roger Burt

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

In viewing the semi-arid conditions of the West Gascoyne, visitors are surprised to see a thriving banana industry at the mouth of the Gascoyne River, 930 kilometres north of Perth. The natural vegetation in the plantation area consists mainly of stunted gums, low acacia scrub and salt bush.

Despite the adverse climatic conditions, the average yields of Carnarvon bananas are double those of banana areas in other states.

Stone Fruit Regulations, W J. Hart

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

Stone fruit grading regulations were introduced for the first time recently to keep small, green or badly blemished fruit off the market. This type of fruit is always in poor demand and can spoil the prices obtained for better lines of fruit by creating the impression of heavy supplies.

New Varieties Could Extend The Peach Canning Season, S R J Newton

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

THE peach canning industry in Western Australia at present has only a limited period of operation, coinciding with the harvest time of the major variety, Golden Queen.

New canning peach varieties tested at Stoneville Research Station could be used to extend the harvest period of canning peaches beyond that of the present standard variety, Golden Queen.

This would have obvious advantages for growers and a canning industry.

The South African variety Keimoes was the most promising canning peach tested. Tests on other varieties are continuing.

Growing And Marketing Yates For Profit, Frank Melville

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

THE YATES APPLE is a late maturing red variety which because of its good storage qualities enjoyed a prominent place on the late market for many years.

The trees grow and crop well, the only disabilities are insufficient colour under some circumstances, small size fruit and a tendency to shrivel.

All these troubles can be successfully overcome by appropriate management.

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

Review of a recent survey of apple and pear plantings in Western Australia.

SINCE the early 1950's the area of apples in Western Australia has continually increased and this has been accompanied by an equally important change in variety emphasis.

On a lesser scale the position has been much the same with pears.

Local Marketing Of Citrus Fruits, K T. Whitely

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

CITRUS fruits are always popular on the local market but recently supplies from South Australia have made the market a very competitive one.

The situation demands the marketing of high quality citrus from growers in Western Australia.

The need to harvest the bulk of the Navel orange crop over a rather limited period and the resultant tendency for oversupply during that time also necessitates high standards of presentation to maintain firm prices.

Ethoxyquin For The Control Of Scald Of Granny Smith Apples, Frank Melville

Root Growth Of Apple Trees, J E L Cripps

Apple And Pear Growing In Western Australia : A Survey Of Trends In Planting, Frank Melville

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

APPLE growing is the major f r u i t growing activity in Western Australia.

The highest production recorded was 2,052,600 bushels in the peak year of 1960-61; of this 1,326,157 bushels were exported.

Western Australia is second only to Tasmania in the quantity exported and at present relies on overseas markets to absorb about two-thirds of the crop.

In 1962 there were 1,304,455 apple trees in this State and the average annual production over the previous five years was 1,449,962 bushels. *
