Why New Land Farmers Need A Super Bounty, Edgar Noel Fitzpatrick
Why New Land Farmers Need A Super Bounty, Edgar Noel Fitzpatrick
Journal of the Department of Agriculture, Western Australia, Series 4
Development of farming land in Western A ustralia's agricultural areas requires the application of large amounts of superphosphate. Since 1963, the Phosphate Fertiliser Bounty applied to superphosphate manufacture has ensured that this superphosphate has been available to farmers at reasonable cost and has helped to make new land development economically worth while.
Originally applied as an incentive to agricultural development, the bounty is now to be withdrawn and it is feared that the resulting increase in the cost of superphosphate will retard development of many West Australian farms and reduce many farm incomes to an unsatisfactory level.
These effects will …

Weed Trials 1974 Summary - Annual Ryegrass Control - Wild Oats - Cereal Tolerance To 2,4-D - Annual Ryegrass Toxicity, G. A. Pearce
Experimental Summaries - Plant Research
A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying …

Grain Moisture And The Weather : What Can The Records Tell Us?, M W. Perry, P. A. Fievez
Grain Moisture And The Weather : What Can The Records Tell Us?, M W. Perry, P. A. Fievez
Journal of the Department of Agriculture, Western Australia, Series 4
The expansion of cereal production in areas along the south coast has exposed harvesting problems associated with high grain moisture.
A grain delivery standard of 12 per cent moisture means that, in the absence of grain drying facilities, harvesting times in the field are restricted to those hours when grain moisture falls below this figure.
Grain moisture, however, remains the major problem and for planning purposes, producers require an estimate of the harvesting time available in a given year. This will depend on all the climatic variables which affect grain moisture. These include rainfall and dew which deposit water directly …
Skeleton Weed : The 1974 Narembeen Campaign, C R. Chambers
Skeleton Weed : The 1974 Narembeen Campaign, C R. Chambers
Journal of the Department of Agriculture, Western Australia, Series 4
Skeleton weed took an alarming, historic turn in Western Australia at the 1974 New Year.
After a decade of an almost complacent pattern—control of one or two small outbreaks annually by the Agriculture Protection Board— general alarm erupted with the discovery of big areas at Pithara and mainly Narembeen.
What followed was a massive movement and engagement of not only Department staff but also the farming community in an attempt to beat this outbreak.

Wheat Breeding, J T. Reeves, N. Roy
Journal of the Department of Agriculture, Western Australia, Series 4
In a normal harvest about 90 per cent of Western Australia's wheat production is exported overseas, where it is used in a wide range of products including noodles, bread, "steamed" bread, chapattis and biscuits
Wheat breeders in W.A. therefore have the problem of developing new varieties suited to many end uses, not all of which have the same quality requirements.
Pasture Seeds : Production Techniques And The Future Market Situation, B J. Quinlivan
Pasture Seeds : Production Techniques And The Future Market Situation, B J. Quinlivan
Journal of the Department of Agriculture, Western Australia, Series 4
Like other farming and grazing industries, pasture seed production has its share of booms and slumps —perhaps more than its share. In Western Australia, the industry reached a high point during the mid-1960's when land development along the south and west coastal districts was at its height.
The drought year of 1969 and the subsequent rural depression saw pasture seed production fall to its lowest level for ten years and it is only in the last 12 months that there has been a revival.
With the sudden upsurge of interest last summer there will be many potential seed producers now …
Nitrogen Fertilisers For Pasture Production, Walter Jacob Cox, K Hawley
Nitrogen Fertilisers For Pasture Production, Walter Jacob Cox, K Hawley
Journal of the Department of Agriculture, Western Australia, Series 4
At current prices nitrogen fertiliser is not an economic substitute for good clover pastures, but it can supplement the system by increasing nitrogen supply at peak growth periods. It can also provide useful increases in pasture production at critical feed times. Nitrogen usage for pasture production is still in the experimental stages and small areas should be tried before large-scale application.

The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis
The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis
Journal of the Department of Agriculture, Western Australia, Series 4
Lucerne, the world's most important fodder legume, has never won largescale acceptance in West Australian farming, largely because of our success with productive subterranean clover pastures. But recent disease problems on sub. clover stands have led to greater interest in alternative species, especially lucerne, for higher rainfall areas.
This article summarises our knowledge of lucerne establishment and management in W.A. and reviews current research aimed at achieving better results from lucerne.
The Effect Of Applied Nitrogen And Subterranean Clover On The Growth Of Doublegee, D J. Gilbey
The Effect Of Applied Nitrogen And Subterranean Clover On The Growth Of Doublegee, D J. Gilbey
Journal of the Department of Agriculture, Western Australia, Series 4
Until 20 years ago doublegees in Western Australia were mainly confined to the red-brown earth soils of the wheatbelt.
Since then, they have spread to light loamy sand soils in the wheatbelt, many of which have carried subterranean clover from the mid-1940s onwards.
It has been widely presumed that the spread of doublegees on to the lighter sandy soils of W.A. can be associated with the establishment of subterranean clover on these soils.
This report summarises the results of a glasshouse experiment on the effect of clover and nitrogen on the growth of doublegee.

Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones
Journal of the Department of Agriculture, Western Australia, Series 4
In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture.

Linseed : A Forgotten Crop, M L. Poole, R. J. Guyton, H. M. Fisher
Linseed : A Forgotten Crop, M L. Poole, R. J. Guyton, H. M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Linseed has become a forgotten crop in Western Australia. From a peak production of 6 200 tonnes from 12 500 hectares in 1969, and an apparently bright future, it dwindled to a bare 80 tonnes from 250 hectares in 1973.
This article looks at some of the reasons for this decline and, with linseed fetching all-time record prices on world markets, gives reasons why the crop should be grown.

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …
