Trends In Viticultural Production, W R. Jamieson
Trends In Viticultural Production, W R. Jamieson
Journal of the Department of Agriculture, Western Australia, Series 4
The viricultural industries are in one of their cyclical downturns. This is nothing new!
What is new is that new factors are coming into play whose exact significance is unknown but will have an important bearing on the economics of a viticultural enterprise.
Effect Of Soil Properties On Copper Availability To Plants, R. F. Brennan
Effect Of Soil Properties On Copper Availability To Plants, R. F. Brennan
Experimental Summaries - Plant Research
Experimental glasshouse work involved examining the decrease in effectiveness of copper fertilizer in the soil through time. This seems to conflict with Mr. J.W. Gartrell's programme of field trials which have shown no evidence for any decline in the effectiveness of the original application. 1. Ammonium cxalate extractable Cu. TABLE 3 - 77GL3.

Ryegrass Disease Could Spread, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The disease annual ryegrass toxicity kills sheep and cattle grazing pastures which contain infected annual ryegrass. In Western Australia the first confirmed outbreak was in 1968 in the Gnowangerup area.
The disease has noe spread over a range of 450 kilometres and with a total area of perhaps 100 000 hectares. because annual ryegrass is the major sown pasture grass in W.A. the disease could spread throughout the South-West.
There are some precautions that can be taken.
Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill
Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill
Journal of the Department of Agriculture, Western Australia, Series 4
Although long known as a potential toxic species because of its content, and although it is widely distribuited in all Australian States, cotton fireweed has not generally been consdidered toxic because it is unpalatable and not usually eaten by stock.
In 1973 cattle deaths occured near Ravensthorpe which led to research into Senecio quadridentatus (cotton fireweed).
The plant must be seen as a potential toxic species in situations where the lack of other feed forces cattle to eat the normally unpalatable cotton fireweed.

W.A. Alert For Aphid On Lucerne, Department Of Agriculture, Western Australia
W.A. Alert For Aphid On Lucerne, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The spotted alfalfa aphid which is devastating lucerne crops in the Eastern States, could be introduced to Western Australia on lucerne hay which is fed en route to imported livestock. The Department of Agriculture has therefore alerted all inspection points about the possible danger.
The Department of Agricultureis maintaining traps specifically for the aphid, and has found no evidence of it yet.
Lupin Trials, J Moore
Lupin Trials, J Moore
Experimental Summaries - Plant Research
Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary.

Preliminary results of research into refrigerated storage of potatoes indicate that the qyality and out-turn are influenced more by the variety of potato stored than by storage conditions.
Economics Of Farm Water Supplies, P P. Eckersley
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 Effect of Septoria nodorum on Yield of 125 Wheat Cultivars. The aim of this experiment was as described for that of 1976. There were some modifications to the treatments which were as follows: (a) Most of the cultivars were 'new' and (b) Three levels of Septoria attack were set up:- 1. Low: cover sprayed throughout the season with the fungicide Difolatan. 2. Moderate: inoculated with Septoria three times, followed at heading out by cover spraying with Difolatan. 3. Severe: inoculated four times no fungicide. The 125 entries were sown as hill plots with the three Septoria environments as main …

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

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.

Bulletins 4000 -
The First W.A. Random Sample Laying Test commenced at the Poultry Research Station, Herdsman Lake in 1957. Every year since that date to 1975 a new test has been conducted up to the Eighteenth Test, which was the last test conducted by the Department of Agriculture. The purpose of this review is to analyse the results of the tests over the years to determine whether the breeds entered in the tests and which are available commercially in this State have made progress. However, before proceeding with the detailed analysis of the test results, an outline of the changes that have …
