Chemical Thinning Controls Biennial Bearing In Apples, J E L Cripps

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

Department of Agriculture experiments have shown that biennial bearing of apples can be controlled by chemical thinning, but both winter and spring weather conditions must be taken into account when the need for spraying is assessed.

BIENNIAL BEARING is a regular cycle in which each heavy crop of fruit is followed by a light crop, or, in extreme cases, no crop at all.

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.

Future Trends In Apple And Pear Production, Frank Melville

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.

Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely

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

DURING the past decade the acreage of Japanese plums in Western Australia has increased by 10 percent, and production has risen by nearly 40 per cent.

Furthermore, almost 30 per cent, of our trees were still classified as non bearing in 1966, so rapid increases in production are certain to be recorded within the next few years.

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.

Why Does Fruit Drop?, K T. Whitely

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

THERE is always a dramatic difference between the number of blossoms that form on a f r u i t tree in spring and the number of fruit which ultimately mature.

This is very obvious to the grower in the " o f f " or light crop year when he feels a personal loss with every young fruitlet or near-mature fruit that falls from the tree.

Citrus Rootstocks : An Evaluation For New And Replant Areas, Department Of Agriculture, Western Australia

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

Widespread decline of citrus orchards in Western Australia associated with Phytophthora root rot, citrus eelworm and other factors has prompted investigation of various citrus rootstocks.

Trifoliata and Troyer citrange are most suitable for replant areas.

Wider use of these and of other stocks such as sweet orange is advocated for new plantings.

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 …

Depletion Of Subsoil Moisture By Apple Trees And Other Woody Species, C. C. Wiggans

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This project began in 1934 and ended in 1955. The work of Kiesselbach, Russel and Anderson indicated that depleted subsoil moisture might be the reason for the loss of many orchards and the injurious effects noted on native woody forest species. Most of the work in apple orchards was done at the University Fruit Farm at Union, Nebraska. Samples were also secured from commercial plantings of apples and other woody species in areas ranging from Rulo, near the Kansas-Nebraska border, to Florence, just north of Omaha, to Lincoln and several points in central Nebraska.

Citrus Water Spot, H L. Harvey

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

WATER SPOT is a disease condition which reduces the quality of citrus fruit in Western Australian orchards during continuous wet winter weather.

The problem is greatest in the Hills districts on navel oranges but mandarins may also be affected. Valencia oranges are rarely if ever affected.

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. *
