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 Northern Grainbelt Of Western Australia 2001, Paul Carmody, Adrian Cox

Bulletins 4000 -

Canola is a member of the Brassicaceae family that 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 varieties B. campestris, the varieties of B. napus have almost completely replaced this earlier variety in all the areas where the crop is grown.

The swing to B. napus varieties was due to their superior yields, resistance to blackleg and better quality oil and meal. Canola can be grown on a wide variety …

Dealing With A Dry Season, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Farmers' approaches to adverse seasonal conditions whether they be frost, flood or low rainfall should be to acquire as much information as possible on the immediate agronomic and financial situations and make a judgement on the longer term implications for the following seasons. Once the information has been acquired, in consultation with advisers, it is necessary to construct and implement agronomic and business strategies to deal with individual situations.

The agronomic and stocking options for the dry season supplied in this booklet deal with questions and issues arising from the Year 2000 season, which has been characterised by a mid …

Cereal Rust Diseases And Their Management, 1999, Rob Dickie, Rob Loughman, Jat Bhathal

Technical Bulletins

• Wheat leaf rust (Puccinia recondita f.sp. tritici) is specific to wheat and triticale. A single pathotype (designated 104-1,2,3,(6),(7),11) has dominated in W.A. since 1990. Wheat leaf rust regularly survives the non-cropping summer in varying quantities, usually sufficient to occur at least to a limited extent (particularly in southern regions) each year. The disease develops rapidly between 15 and 22°C when moisture (including dew) is non-limiting. The highest yield increase attributed directly to control of leaf rust in W.A. is 37 per cent. However the disease is synergistically damaging in combination with septoria leaf blotches. In Esperance in …

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow

Bulletins 4000 -

This Bulletin discusses the benefits that furrow sowing brings to crop growth and production on water repellent sand, based on research and farm observations in Western Australian. By understanding the benefits and risks of several key processes, producers can better evaluate the potential role of furrow sowing in combating water repellency. This is true whether one is using direct drilling, no-till (narrow points or discs) or zero till (single, double or triple disc openers) methods.

Bulletin 4294 - Virus Diseases Of Lupins, Roger Jones

Bulletins 4000 -

Two virus diseases pose a serious threat to lupins. These are caused by cucumber mosaic virus (CMV), which induces diseases in narrow-leafed and yellow lupins, and bean yellow mosaic virus (BYMV), which infects all types of cultivated lupins. The effects of the viruses on lupin plants range from subtle colour changes and leaf distortion to leaf shedding, stunting and death. Seed production is decreased or prevented. There is no cure, but lupin crops can be managed to minimise both virus spread and its persistence from year to year.

CMV and BYMV occur within all tissues in the plant, but do …

Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason

Bulletins 4000 -

Because fertiliser prices are high, it is important to understand what affects the response to fertilisers by crops.

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, you need some understanding of how these factors work.

Greatest responses to nitrogen fertilisers can be expected in areas with a relatively long growing season. In such areas light soils with a low nitrogen status give the …

Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster

Bulletins 4000 -

Wide furrow sowing is a method for successfully establishing crops of lupins or cereals on non-wetting sands, and improving crop establishment on non-repellent sands. The same principles can be used to assist establishment of fodder shrubs and long-term pasture (e.g. tagasaste and Rhodes grass).

Analysis Of Black Point In Wheat, J M. Wilson

Technical Bulletins

Fungal staining (black point) of wheat can reduce the quality of grain. The most serious problem is a discolouration of products. Discolouration is a consequence of infection by microorganisms. The most likely cause in Western Australia is a species of the common fungus Alternaria. Infection and discolouration occur between flowering and grain maturity, and the optimum environmental conditions are probably consecutive days of high relative humidity together with warm temperatures.

Managing For Stubble Retention, Linda Leonard

Bulletins 4000 -

One of the objectives of sustainable farming systems is to retain as much cover on the soil as possible – this helps to maintain soil structure and protects the soil from erosion.

Improving productivity, maintaining soil structure, and stabilising fragile soils are some of the desired aims of farming. Sound rotations, reduced tillage, effective use of herbicides, maintenance of ground cover and careful management of stock are part of the management process used in achieving these goals.

This Bulletin provides an introduction to stubble retention systems. Its purpose is to create an awareness of the benefits and principles of stubble …

Visions For Agriculture, Department Of Agriculture, Western Australia

Agriculture reports

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Quest For Quality Operation Quality Wheat, Sue Bestow

Agriculture reports

Variations in the protein content of wheat are largely associated with growing conditions, particularly rainfall and soil type, which influence nitrogen supply and crop yield. Management to improve protein generally also improves yield, so in future both must be considered when comparing profitabilities of management options, particularly if payment for protein increases.
