Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.
It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.
West Midlands Development : Sources Of Credit For Farmers, J T. Stoate
West Midlands Development : Sources Of Credit For Farmers, J T. Stoate
Journal of the Department of Agriculture, Western Australia, Series 4
RAPIDLY increasing costs associated with land development and farm improvement have placed heavy financial burdens on farmers.
At the very least such burdens must often slow the rate of development, increase family hardship and lower farm profitability.
Many farmers however, are unaware of the sources of loan money which could help them overcome their problems.
This article outlines some of the credit sources available.

Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason
Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason
Journal of the Department of Agriculture, Western Australia, Series 4
Generally similar results may be expected from all the sources of nitrogen available for cereal growing.
The unit nitrogen price and the convenience of use of each fertiliser in the particular situation should be taken into account in deciding which fertiliser to use.
THE first point to consider when deciding which nitrogen fertiliser to use for wheat growing is the effectiveness of the nitrogen source in increasing crop yield. Second, the cost per unit of nitrogen must be considered.
The convenience of using a particular source in a particular situation is also important and greater convenience may offset some cost …

Local Marketing Of Citrus Fruits, K T. Whitely
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.

Amsinckia Or Yellow Burr-Weed (Amsinckia Spp.), G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
YELLOW BURR-WEED is widely established in the Wimmera and Mallee districts in Victoria, presumably introduced with fodder brought to this country from the United States about 1914.
It is a problem in Oregon and other north west wheat areas of America.
The weed is also widespread in New South Wales, being most troublesome in the wheat-growing sections of the Riverina. It is not established to the same extent in South Australia and Queensland.
The recent discovery of areas infested with yellow burr-weed at Merredin prompted the Agriculture Protection Board to declare it a primary noxious weed for Western Australia.

The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer
The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer
Journal of the Department of Agriculture, Western Australia, Series 4
ROSE CLOVER is being produced and used in increasing quantities in south-western Australia. The first line named was designated Kondinin and five lines have now been given cultivar (variety) names.
One of the first samples of rose clover, C.P.I. 13949, introduced into Western Australia proved to be a mixture of two very similar types, differing visibly only in leaf markings.
The mixed sample was named Troodos,* and the selection from it, Olympus.
This paper describes the origin of the two varieties, their history and characteristics.

Bluetongue Of Sheep, M R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
BLUETONGUE is a serious disease of sheep, mainly of introduced European breeds, throughout the African continent.
It is maintained there by wild and domestic ruminants in the presence of certain insect vectors (carriers).
The disease has probably existed there from immemorial times among the indigenous ruminants, emerging as a recognised disease only when the much more susceptible European breeds were brought into the continent.
