Why Not Take Another Look At The Loquat?, W J. Hart

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

Loquats were introduced to Australia in New South Wales in the early days of the colony.

Although they hare since been established throughout the country, loquats have never found a prominent place in the horticulture industry.

In this article W. J. Hart of the Horticulture Division says Why not take another look at the loquat ?

Linseed Growing In The Ord River Valley, D F. Beech

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

Experimental work with linseed at the Kimberley Research Station began in 1952 and has been intensified in the last four years.

Fertiliser requirements and methods of land preparation, sowing, irrigation and weed control have been established.

Suitable varieties have been selected. Farm-scale crops have been grown in the area and, although cotton is very much more remunerative as an establishment crop, it is expected that linseed will ultimately have a place in the Ord irrigation scheme.

The Production Of Arsenous Gases By Wood-Rotting Fungi, William Merrill, D. W. French

Journal of the Minnesota Academy of Science

Approximately 120 years ago in Europe is was learned that certain fungi liberated arsenous gases when they were grown on substrates containing arsenic. This was especially apparent when certain molds grew on paste on wall paper in damp rooms, converting arsenic-containing pigments in the wall paper into a gas with a garlic-like odor. This resulted in numerous cases of arsenic poisoning of people living in these rooms; some of these people died. The identity of the gas was unknown until 1932 when Challenger and his co-workers demonstrated that it was trimethylarsine ( CH3 )a As ( 3). Several species of …

Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

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

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.

The Doublegee, G R W Meadly

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

DOUBLEGEE, like a number of other major weeds, is native to South Africa. It was introduced to Western Australia during the first years of settlement.

There is no more troublesome weed in Western Australia than doublegee. It competes strongly with crop and pasture and its spiny fruits penetrate the hoofs of stock, causing lameness.

Bracken Fern Poisoning In Cattle, P B. Lewis

A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms

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

The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.

When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

Deep Sowing Of Wheat : The Effect On Root Systems, S C. Chambers

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

DEEP sowing appears to be an important cause of poor emergence in wheat and care should be taken to seed at the recommended depth of 1 to 1J inches.

Nevertheless some growers in drought liable areas, persist in sowing at 2 to 3 inches in the belief that it will encourage a deep root system.

The Mango In Western Australia, K S. Cole

Take-All Of Wheat On The Esperance Downs, S C. Chambers

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

THE agricultural development of the Esperance Downs was reviewed recently by Shier, Dunne and Fitzpatrick (1963) who indicated the great potential of this region.

They described the establishment of clover ley pastures capable of supporting heavy stocking rates. Crops of oats or linseed also give excellent returns.

Weed-free rotations which include linseed, oats or vetches may reduce wheat losses caused by take-all on the Esperance Downs.

Pruning Citrus Trees. 2. Pruning The Mature Tree, D B. Argyle

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

EXAMINATION of a mature tree in full production will show the natural pattern of growth already explained.

It will be seen that over the years the frame has developed by a system of layers with new growth, stimulated by sunlight, constantly appearing on the top side of the older wood.

Eventually the terminal portions of the older layers are weakened by lack of light, they become unproductive and in turn adversely affect the general fruitfulness of the rest of the tree by shading and crowding.
