Effects Of Tactical Responses And Risk Aversion On Farm Wheat Supply, Ross S. Kingwell

Natural Resources Research Articles

A discrete stochastic programming model of the farming system of the eastern wheatbelt of Western Australia is used to examine the effect of tactical responses and risk aversion on wheat supply. Including within-season tactical changes to wheat areas decreases the own-price elasticity of supply. By contrast, introducing risk aversion has no consistent effect on the own-price elasticity of supply. The implications for supply models are discussed.

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

Bulletin Ma 1/95 - Cauliflower Growing In The South West, M. Shellabear, D. Phillips

Horticulture published reports

Manjimup Regional Office

Agdex No 254/11

Cauliflower (Brassica oleracae, variety botrytis) is closely related to cabbage, broccoli, brussel sprouts and kohl rabi. This group of plants may be referred to as crucifers, brassicas or cole crops.

The cauliflower probably developed in Italy from broccoli. The head is the short. thickened part of the immature flowers, before these have differentiated into flower-buds. Cauliflowers are the third most valuable vegetable crop grown in WA.

Understanding Fertilisers For Table Grapes, B. H. Goldspink, I. Cameron, J. Campbell-Clause, N. Lantzke, C. Gordon

Viticulture research reports

A course run by the Department of Agriculture, Western Australia, August 1995.

The purpose of this publication is to clarify the role fertilisers play in commercial table grape production and to detail methods of selecting fertilisers. This selection process however is not easy as there are over 600 registered fertilisers in Western Australia.

In deciding which is the best fertiliser for a particular property many factors have to be considered. These include:

* Age of vine

* Rootstock

* Variety of table grape

* Soil type

* Soil chemistry

* Irrigation methods

* Previous fertiliser history Previous yield, vigour and …

Canola essentials:

Site selection -Paddock selection is critical for a successful canola crop. Avoid paddocks with waterlogging, wind erosion and broadleaf weeds - particularly wild radish, turnip, mustard and doublegees.

Soil type - Canela grows well on most soil types, however it prefers well drained gravel soils, red loams, sandy _loams and deeper duplex soils. Soil pH levels (in CaCl_²) of 4.5 to 8.0 are suitable. Soil test paddock for pH, phosphorus, and potassium levels.

Rotation - Grow canola after manipulated pasture, lupins or other grain …

Msda A Machinery Selection Decision Aid For Stubble Management Practices, Linda Leonard, Andrew Green

Grain and other field crops published reports

MSDA is a user friendly program developed to help farmers predict stubble outcomes before acting on their management practice. This manual is an accompaniment to a computer program designed on Micorsoft Excel-macros. Its aim is to help farmers assess their current machinery and stubble handling ability and view options that may be adopted as best practice for their properties.

The program is designed with the complete season in mind. Information is gathered on the full complement of machinery used from harvest through to seeding, to allow farmers to see all choices available and enable them to choose the best system …

Delaying The Development Of Herbicide Resistant Ryegrass By Using Alternative Weed Control Strategies, A. J. Diggle, G. S. Gill, J. E. Holmes

Biosecurity published reports

Alternative strategies to control ryegrass in wheat lupin rotations are worth approximately 15 dollars per hectare for each 50% reduction achieved in plant or seed numbers. This figure has been calculated for circumstances similar to those found at Wongan Hills, and it holds in all cases where ryegrass is still under control using standard herbicides.

Farmers should adopt any ryegrass strategy in addition to that normally practised, so long as the cost to control ratio is less than $15/ha/50% kill. This applies even where good control is being achieved using grass selective herbicides, regardless of the number of previous applications …

Growing Lettuce, Margaret Graham

Horticulture published reports

The commonly cultivated lettuce, Lactuca sativa, is an annual belonging to the sunflower family. It has been cultivated for over 2500 years, and is a popular salad vegetable.

There are three main subspecies commonly grown.

• IL. sativa ssp capitata - Head type - Crisphead is a lettuce with a firm head and brittle leaves. It is the major lettuce type grown in Australia and is also known as iceberg lettuce. - Butterhead (buttercrunch, mignonette) lettuce has soft, pale leaves and a delicate buttery flavour. It is of major importance in Europe, where it is grown as a greenhouse crop.

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …
