Cereal Crop Tolerance To Herbicides, D Bowran, R Madin, A Lindsay Jan 1984

Cereal Crop Tolerance To Herbicides, D Bowran, R Madin, A Lindsay

Experimental Summaries - Plant Research

The 1984 experimental programme was a continuation of that started in 1981. The programme was aimed at evaluating the major herbicides in current use for cereals as well as new herbicides against the recommended varieties at three main sites, these being Wongan Hills, Merredin and Mt Barker. In addition Stage 4 breeding lines were evaluated against the same herbicides but only at Wongan Hills. The herbicides used and their rates and time of application are presented in Table 1. Herbicides were applied at both the recommended and twice the recommended rates of application, except in the breeding line trial where …

Foliar Disease Of Wheat, A. G. P. Brown Jan 1984

Foliar Disease Of Wheat, A. G. P. Brown

Experimental Summaries - Plant Research

Wheat leaf diseases were at much reduced levels in 1984. This may have been caused by prolonged summer rain prematurely setting off dispersal of spores and also initiating microbiological breakdown of stubble residues. No survey was carried out in 1984 but a good indication of the seasonal effect can be gained by noting that in the spray-timing experiment at Badgingarra disease levels were extremely low until the end of August some 90 days after sowing.

Breeding Wheat Varieties For Acid Soils, I R. Barclay Jan 1984

Breeding Wheat Varieties For Acid Soils, I R. Barclay

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

Wheat varieties with improved tolerance of acid soils cold increase yeilds be perhaps 20 per cent or more over a substantialarea ofWestern Australia's eastern wheatbelt.

Aluminium toxicity is probably the main cause of poor root growth and therefore reduced yields on these soils.

Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen Jan 1984

Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen

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

If modified fertiliser practices are adopted phosphorus losses from the Peel-Harvey catchment can be reduced. Farmers can save money on fertiliser applications and the need for more expensive catchment management measures to reduce algal pollution of the estuary will be avoided.

Research data available so far indicate that, with farmer co-operation and the use of the new slow release fertiliser New Coastal Superphosphate, long-term phosphorus application rates can be reduced by 30-40 per cent - and possibly even halved - without lowering agricultural production. This will also reduce phosphorus loss to drainage water.

Although much of the research since 1982 …


Soil Acidity On High Rainfall Pastures, J S. Yeates, D. A. Mcghie, I. R. Wilson Jan 1984

Soil Acidity On High Rainfall Pastures, J S. Yeates, D. A. Mcghie, I. R. Wilson

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

Most soils of the high rainfall area of south-western Western Australia are naturally acis.

The most acid group of soils, the peaty sands. have been routinely limed before subterranean clover pastures were established since research in the 1950s showed that poor Rhizobium nodulation could be overcome with the application of about 2 tonnes per hectare of coastal limesand.

Molybdenum Deficiency In The Wheatbelt, M M. Riley Jan 1984

Molybdenum Deficiency In The Wheatbelt, M M. Riley

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

The trace element molybdenum is needed in very small amounts in nitrogen metabolisms of crops and pastures. One of the projects that started as a result of the overall soil acidity research programme was the examination of molybdenum deficiency on acid soils throughout the South-West of Western Australia.


Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson Jan 1984

Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson

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

In Western Australia parts of the sandplain of the eastern wheatbelt are very acid and produce poor crops, It was not until the late 1970s that the effect of soil acidity on the productivity of the sandplain soils was examined in any detail.

Since then researchers have learnt a great deal about the nature of soil acidity in the eastern wheatbelt sandplain soils and can suggest management options for farmers.

This article discisses the problem of the very acid soils. It does not deal with the moderately acid, medium textured soils of the eastern wheatbelt. Although the acidity of these …

Barley Production And Soil Acidity, P J. Dolling, W. M. Porter

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

One of the causes of reduced plant yields on acid soils is aluminium toxicity. because barley is extremely sensitive to this mineral, a project started last year to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia.

This article discusses some of the background information on the project and its aims.
