Options For Machinery And Labour, A F. Herbert

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

Machinery is one of the highest costs in farming today. It is not unusual for capital investment in machinery to be 20 to 30 percent of the total investment in the farm.

On an annual basis, expenditure directly attributable to machinery can be 40 per cent or more.

This article cannon be a panacea for everyone to reduce machinery costs - each farm is different. But some of the issues might be of help.

Barley Yellow Dwarf Virus In Barley And Oats (79mt20, 79pe13) Experimental Summary 1979, G D. Mclean, T N. Khan, M Grimm, J D. Sandow

Experimental Summaries - Plant Research

(1) Yield assessments have continued similar to those used in 1977 and 1978. Essentially, plants with symptoms typical of BYDV are marked in the early spring as well as a similar number without symptoms. Yield differences were obtained both for Clipper Barley and an oats variety. (2) Two pilot experiments using viruliferous aphids were carried out at Mount Barker (79MT20) and at South Perth · (79PE13). Both Rhopalosiphum padi and R. maidis were used. Infection at Mt Barker failed, and therefore no data is presented. The Perth experiment was planted on August 31, 1979. The original plan was to have …

Phomopsis infection of 96 entries (replicated) was assessed just prior to harvest at seven sites - Chapman Valley Research Station (CVRS), Badgingarra Research Station (BRS), Wongan Hills Research Station (WHRS), Avondale Research Station (ARS), Mount Barker Research Station (MBRS), Esperance Downs Research Station (EDRS) and on a farmer's property at Eradu. At four sites, CVRS, Eradu, MBRS and EDRS, only very low levels of infection were apparent. At the other three sites, the currently available varieties …

Getting The Best From Tractor Tyres, J Quealy

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

The amount of pull a tractor develops depends largely on tyre efficiency and so with so many tyre size options for the one tractor model it is very easy to make the wrong decision on tyre fitment.

Tyre efficiency varies with tractor weight, soil conditions, inflation pressure and tyre size.

Hers we look at some of these factors and how changing them may affect efficiency.

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett

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

Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.

Fallow Re-Assessment, D Tennant

Experimental Summaries - Plant Research

Fallow re-assessment. I. 72M29. Location - Merredin Research Station II. Other fallow results. As part of the fallow re-assessment project, a study was made of results from all trials done since the early 1920's which either compared fallow with non fallow or examined other aspects of fallowing. Analysis of these data has led to an update of some of the rainfall - soil water storage - yield relationships presented in previous reports. On the basis of these rainfall-yield relationships and of relevant rainfall statistics we can make an assessment of the probable value of fallow at different locations; Merredin; Chapman, …
