Trial 87WH51
Location: Wongan Hills Research Station.
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

A Guide To The Identification And Control Of Insect Pests In Maize Crops Grown Int He Ord River Irrigation Area, S.E. Learmonth
Grain and other field crops published reports
The importance of insect pests in Ord maize crops is seasonal both in terms of their abundance and the species present. It is therefore desirable that the main pests of maize can be recognized quickly and appropriate action taken to avoid crop loss
In this guide, all of the common insect pests likely to be encountered in Ord maize crops are described. Photographs of only the more important of these and some of their natural enemies are included. Any insect that cannot be readily identified may be taken to the office of the Department of Agriculture.

Harvesting Methods In South Coastal, High Rainfall Crops, Richard Snowball
Division of Plant Research : Technical Report Series
Results of trials carried out in south-western Australia over the past three years have shown that swathing or windrowing cereal and legume crops can result in significant advantages to growers.Swathing barley, wheat and oat crops at Mt. Barker resulted in large yield advantages over direct harvesting of standing crops. This was a result of overcoming shedding losses in the standing crop caused by strong wind and rain. Grain quality of barley and oats was not significantly affected by swathing, however, the quality of swathed wheat was sometimes worse than direct harvested grain if the harvest was delayed.Swathing cereals at Newdegate …

Nitrogen Fertiliser Use For Cereal Hay Production, M G. Mason
Division of Plant Research : Technical Report Series
Aspects of the effect of nitrogen fertilizers on cereal hay production in twenty-one experiments carried out over eight seasons were investigated.Areas investigated include the effects of rate and time of application of nitrogen fertilizer, sowing rate, date of sowing, crop species and variety and time of cutting on cereal hay yield, nitrogen content and digestibility.Response to nitrogen fertilizers in hay and grain production varied but profitable responses were more common, and optimum rates were higher for hay than for grain. Average optimum rates for hay were 51 to 88 kg nitrogenha-1 and for grain 0 to 44 kg nitrogen ha-1. …

A small experimental farm was first established on the Ord River in 1941. This farm was relocated in 1945 to what is now known as the Frank Wise Institute of Tropical Agriculture.
The first stage of the Irrigation Scheme which included the Diversion dam was completed by 1963 and by 1966, 31 irrigated farms had been established.
In 1967 the second stage was commenced and by 1972 the main dam had been completed.
Cotton was the major crop until 1974. In the wet season of that year 3642 hectares was devoted to cotton. Various crops such …

Preventing Lupinosis With Phomopsis-Resistant Lupins, Jeremy G. Allen, W. A. Cowling
Preventing Lupinosis With Phomopsis-Resistant Lupins, Jeremy G. Allen, W. A. Cowling
Journal of the Department of Agriculture, Western Australia, Series 4
Lupinosis is one of the major livestock siseases in Western Australia. It is caused by stock eating toxins produced by the fungus Phomopsis leptostromiformis which colonises the stems of dead lupin plants.
In 975, the Department of Agriculture started a breeding programme to develop Phompsis-resistant lupins to overcome or control lupinosis. In the previous issue of this Journal the results of small plot evaluations of new lines of Phompsis-resistant lupins developed in this programme were reported. This article describes the first trial involving grazing of Phompsis-resistant lupins.
Barley Breeding Update, P A. Portmann
Barley Breeding Update, P A. Portmann
Journal of the Department of Agriculture, Western Australia, Series 4
Barley production in Western Australia has increased over the past few years, peaking at 1.42 million tonnes in 1984. The European Economic Community, however, has flooded world markets for barley and over half of ourbarley was sold for feed to Saudi Arabia last year. Current prices therefore have declined as has the total area sown to barley in this State.
Despite this, the potential to increase barley yields is most promising. The Department of Agriculture has cross-bred lines in advanced stages of field testing which could increase yield by 10 per cent across the agricultural areas.
In the longer term, …

Increasing Wheat Yields Through Breeding, B R. Whan, R. Gilmour
Journal of the Department of Agriculture, Western Australia, Series 4
With the current 'cost price' sueeze facing Australia's farmers, the development of new higher yielding varieties is moe important that ever. By growing higher yielding varieties, farmers can increase their returns at virtuakky no additional cost: for example a wheat variety that produces 5 per cent extra yield from 1 t/ha crop returns about an additional $8/ha. Farmers can therefore increase their production by growing improved varieties.
Agricultural Progress On The Ord, D A. Mcghie
Agricultural Progress On The Ord, D A. Mcghie
Journal of the Department of Agriculture, Western Australia, Series 4
This is the first of occasional articles describing the experimental and commercial activity on the Ord River Irrigation Area (ORIA) in Western Australia's Kimberley region.
Against a background of extensive recources of land and water, a sometimes cimatic advantage and a complementary disadvantage of a remote location, agriculture on the Ord has swung from various monocultures to a broadly based and diversified production. In 1986, the value of agricultural production on the Ord will approach values equivalent to those of the cotton era for the first time since the demise of that industry 12 years ago.
Phomopsis Infection Of Lupin Seed, D S. Petterson, P. Mcr. Wood
Phomopsis Infection Of Lupin Seed, D S. Petterson, P. Mcr. Wood
Journal of the Department of Agriculture, Western Australia, Series 4
Early reports of lupinosis in Western Australia implicated infected stems and leaves of the sandplain or W,A. blue lupin (Lupinus cosentinii) as the main source of toxicity.
After the introduction of low alkaloid varieties of L. augustifolius, lupinosis continued to oddur on stubbles but random testing of seeds showed only low levels of Phomopsis leptostromiformis infection.
However in 1976, scientists at the University of Western Australia who were evaluating the use of an all lupin seed ration for drought feeding sheep encounted lupinosis in one of their trials.Seven per cent of the seed used was found to be infected …

Serradella Prospects At Esperance, Michael D A Bolland
Serradella Prospects At Esperance, Michael D A Bolland
Journal of the Department of Agriculture, Western Australia, Series 4
Yellow serradells is a promising introduced annual legume suitable for some of Western Australia's well drained sandy acid soils where other pasture legumes failto persist.
In the Esperance area serradella grows siccessfully on some sandy soils more than 0.5 metres deep. I develops deep roots rapidly - up to three times deeper than subterranean clover - and this is probably the main reason for its persistance.
At present only two late maturing, registered serradella cultivars are available to farmers in southern Australia. This article describes research at Esperance to delect earlier flowering cultivars for persistence in areas with less than …

Experiments were set up to screen a range of herbicides which might give improved control of Anguina agrostis over the currently recommended paraquat. Two experiments examined Roundup, Fusilade and Sertin at two rates and two experiments screened eight herbicides at five rates from two x "label recommendation" to 0. 99 x Standard treatment was paraquat at 550 ml. Plots were 3 m x 30 m in the first two experiments and 3 x 5 m (per dilution) in the second. The herbicides were applied on 4/9, 17/9, 24/9, 1/10 and 9/10 (Zadoks stages 32 - 58). There were three replications …
