Wimmera Rye Grass : Major Pasture Grass Of The Cereal And Sheep Areas, H G. Cariss

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

MANY of the volunteer pasture species of the cereal and sheep areas seed profusely, persist well and produce useful early green feed.

Mostly, however, they produce poor quality herbage of low forage value, particularly during the spring and summer months.

The seeds of many species cause problems in stock husbandry and lower the value of wool.

Facial Eczema In West Australian Sheep, M R. Gardiner, M. Nairn

Castor Beans In Trial Plantings : Bundidup Research Station, Wokalup, 1959-60, T Pavy

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

THE main producing countries of the world are Brazil, India, U.S.S.R. and U.S.A. This means Australia has to import her supplies of castor oil, which has led to great interest in the possibility of growing castors in Australia.

Since the turn of the century, this interest has been increasing, and has accelerated in recent years, but it has never passed the experimental stage.

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

Avoid Losses From Poison Plants, Robert Dunlop Royce

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

E VERY country in the world has its poisonous plant problems, but in Western Australia we have more than our share.

Farmers in "Poison" districts can avoid serious stock losses if they can recognise dangerous poison plants, and have a knowledge of how the concentrations of toxic substances in these plants change with the seasons.

In this article, R. D. Royce, Officer in Charge of the Botany Branch, outlines the principles involved.

Winter Pests In The Pasture, P N. Forte

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

ALTHOUGH the pests concerned in attacking winter pastures are known to most farmers a discussion of their control and relative importance will not be out of place.

The principal pests concerned fall into two groups. Firstly the red-legged earth mite and lucerne flea whose attacks are most noticeable soon after germination and secondly a group of caterpillars which appear about the same time and whose attack is not noticed until a large amount of damage has been done.

Salty Seepages Can Be Productive, C V. Malcolm

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

MUCH has been said and written concerning the use of Paspalum vaginatum for growing on seepage areas, but the general production to be expected from seepage areas has not received much attention.

The fact is that properly handled, seepage areas can be quite productive, and can be valuable for summer grazing.

Salt Land Management : Too Early To Graze Bluebush, Department Of Agriculture, Western Australia

Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.

Bluebush Seed Supplies, C V. Malcolm

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

A GREAT deal of publicity has been given of late to the value of bluebush (Kochia brevifolia) as a plant for some types of salt-affected land, particularly in the drier parts of the wheatbelt.

Obtaining seed supplies can be a problem, but fortunately large amounts of seed are not required since once a few bushes are established they will spread seed over the intervening areas.

Thus rates of 1 to 2 lb of seed per acre have been found quite satisfactory.

Geranium Rust, Department Of Agriculture, Western Australia

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

GERANIUMS are affected by relatively few troublesome diseases. However, in Western Australia, leaf rust of these plants is very common and can become a serious problem, particularly in the more susceptible varieties growing in sheltered positions.

Leaf Scorching, Department Of Agriculture, Western Australia

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

DURING the summer months, leaves of many plants develop browning and scorching which progresses inwards from the leaf margin or downwards from the leaf tip.

The affected parts become dry and brittle and may break away from the remaining green areas.

Ornamental trees, shrubs and other plants, certain orchard trees and in fact a large number of species may be affected.

Two plants which are very susceptible to this type of injury and are rarely seen without it are the Ioquat tree and the butterfly tree (Bauhinia).

Rice Stem Borers At The Kimberley Research Station, L E. Koch

This popular pasture plant is believed to have originated as a natural cross between two ryegrass species and first became prominent in the Wimmera district of Victoria.

Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox

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

THE establishment of the Wiluna office of the North-West Branch marked the commencement of a series of investigations into the pastures of the mulga zone.

Unlike the agricultural areas where a fund of knowledge exists on the growth habits of the pastures, the pastures of this area were completely unknown.

The preliminary investigations had to be aimed at forming an understanding of the reactions of the various plants to rain, to temperature and seasonal conditions and to grazing in an area of extremely low rainfall reliability.
