The Doublegee Problem In Western Australia, D J. Gilbey

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

Doublegee is native to South Africa and is now naturalised as a serious weed of crops and pastures throughout the temperate areas of Australia.

Doublegee was introduced for cultivation as a vegetable by English migrants to the Swan River Colony in 1830, and a bed of doublegees is known to have been sown at Mr. J. Phillips' property on the Canning River in 1833. However, the plant soon became a troublesome weed and its name was changed from Cape spinach to Tanner's curse and later to doublegee.

More than 180 doublegee seedlings per square metre have been counted in a …

Kenaf : A Possible Multi-Purpose Crop For The Ord River Irrigation Area, I M. Wood

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

Kenaf is a tropical crop which shows promise for use in paper pulp, oil and protein production; the young growth is a nutritious animal feed.

It has proved a highly productive crop in the Ord River Irrigation area, raising speculation about its possible use as a commercial crop there. In this article a CSIRO research worker describes the properties of kenaf and reviews research results with the crop on the Ord

Peanuts For The Ord, Department Of Agriculture, Western Australia

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

Peanuts were extensively tested in experiments on the Ord River in the early 1950s, but it is only recently that varieties better adapted to heavier soils have re-opened prospects of commercial production.

The new varieties remain dormant after maturity and an irrigation just before harvesting allows the crop to be lifted with the soil friable enough to reduce harvesting losses and the amount of soil sticking to the kernels.

These varieties have been extensively tested in Department of Agriculture trials at Kimberley Research Station since 1958, and preliminary recommendations for crop production and pest and disease control have been formulated.

Docks In Western Australia, J M. Allen

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

A survey carried out by the Department of Agriculture has shown that docks are the most serious weed of the higher rainfall areas of Western Australia. They are estimated to cost farmers $400 000 annually in lost production. One of the main reasons why they are important weeds is that they regenerate rapidly from tubers and compete with desirable annual pasture species. Also the upright dock flowering stems are woody and unpalatable. Individual plants become intertwined and deter stock from grazing summer pastures.

Results from the survey of the dock problem are given in this article. The findings show that …
