Identifying Soil Constraints That Limit Wheat Yield In The South-West Of Western Australia, Dennis Van Gool

Resource management technical reports

Wheat is grown on about 18 million hectares in the South-West Agricultural Region of Western Australia from north and east of Geraldton to Esperance in the south-east. Yields are frequently constrained by a range of soil factors.

This report uses existing conventional soil-landscape mapping to analyse the effects of 17 known soil constraints that limit crop production and roughly prioritises the areas where they occur.

Traditional land capability maps are prepared using a most-limiting factor approach, which assumes that ameliorating the most limiting constraint will result in a yield increase until the next most-limiting constraint is reached. Where there are …

Profitable Canola Production In The Great Southern And Lakes District, Paul Carmody, Ashley Herbert

Bulletins 4000 -

The Canola industry has rapidly grown with a 10 fold increase in area sown in Western Australia over the four years from 1996-99.

The driving force behind this increase in area can be attributed to the successful adoption of weed control technology in Triazine Tolerant Canola.

By knowing the model of the limiting factors, which are usually; weed control, fertiliser practices, blackleg management, variety selection, seeding dates, seeding depths, insect control and swathing, we can make the right decisions and achieve the targeted profit.

To produce yield to potential, all factors need to be optimised, otherwise yields will be decreased …

Profitable Canola Production In The South Coastal Region 2000, David Eksteen

Bulletins 4000 -

Why grow canola in the South Coast Region? Canola is a member of the Brassicaceae family, which also includes mustard, turnip, wild radish, cauliflower, cabbage and broccoli. It is a winter growing oilseed that can be produced in most arable areas of Australia where winter crops are currently grown. Originally known as rapeseed using the species B. campestris, the species of B. napus have almost completely replaced this earlier species in all the areas where the crop is grown.
