Annual Medicago Ecotypes From North West Libya, M Khalil, C M. Francis, N J. Trotman

Technical Bulletins

Nine Medicago species were represented in collections from 10 sites in North West Libya. This report outlines species distribution, maturity characteristics and coumestrol content of the ecotypes collected. Medicago laciniata was the most common species collected but there appeared to be a relationship to soil type amongst other species. M. truncatula predominated on heavier textured soils but M. tornata and M. littoralis were more frequent on sandy soils. The Libyan ecotypes were typically early flowering with a rapid rate of burr maturation. They contained low to moderate levels of the plant oestrogen coumestrol in dry stems. Evaluation work was carried …

Economics Of Farm Water Supplies, P P. Eckersley

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

The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.

I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

The Philosophy Of Drenching Sheep In Western Australia, G C De Chaneet

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

Sheep of all classes are drenched more or less regularly throughout the agricultural areas of Western Australia.

Much of the drench is wasted because it is used in the wrong circumstances. This situation is probably a result of poor understanding of drenching.

This article discusses the philosophy of drenching and attempts to relate this to the epidemiology of parasitism as it is currently understood.

Serradella : A Pasture Legume For Sandy Soils, John Sylvester Gladstones, N. R. Mckeown

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

French serradella grows well on many of the sandy soils along the west coast where other species such as sub clover often fail, and produces excellent feed both when green and in the dry state.

Establishment is easy because of its soft seedednedd. However the same characteristic, together with its erect growth habit, means that persistence under grazing has been poor.

This paper looks at work being done to understand the requirements to maximise results from serradella and develop better varieties.

Phosphorus Fertilisers For W.A. Farming, Michael D A Bolland

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

Phosphorus is one of the major nutrients essential to plants. Eithout the use of phosphorus fertilisers, few soils in Western Australian sagricultural areas would be agriculturaly productive.

Superphosphate has been the major source of phosphorus fertiliser used in W. A..

Now there is a possibility that the alternatives to superphosphate may be cheaper

Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing

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

The Department of Agriculture, in conjunction with the Farm Water Supply Advisory Committee, has conducted farm wster supply surveys in many districts in the wheatbelt.

The aim of the surveys was to collect data to assess the existing water supplies, the potential for further water supply developments and to compare the relative difficulty of water supply development in different localities.

Native Plants : Water Savers In The Garden, K S. Cole

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

The climate of Western Australia may be one of the best in the world for people but it is a difficult one for many of our imported, and common garden plants. as a consequence, some 70 per cent of our summer water usage is for gardens and lawns.

This is not the sort of statistic that we should accept easily or happily.

There is a solution to this problem: a new approach to home gardening is required.

The new garden is based on W. A.'s own colourful native plants, which are adapted to mild winters, hot dey summers and poor …

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

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

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

Cereal Foliage Disease Survey A dry season reduced disease to insignificant levels (as measured by this survey) in all areas except the south west. Late rains may have produced some damage to wheat by S. nodorum however but this was probably confined to southern areas. In barley net blotch which has been declining re appeared a major disease in 1977 excepting high rainfall areas, where scald continued to be severe. The level of scald infection was considerably lower which may be associated with relatively higher temperatures and low rainfall. Variety Clipper continued to show high degree of tolerance to net …
