Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

Overall, our conclusion is that while many current uses of yield maps will tolerate low to moderate GPS error, the inability to procure accurate GPS signals will hinder the development of more sophisticated applications of the information for the interpretation of crop behaviour and machine guidance... SSC's limit crop production by limiting crop rooting depth limiting effective plant available water content (PAWC), as well as having direct toxic and nutrient imbalance effects 3... The proportion of the total seasonal water use which is used by a crop after flowering goes a long way to determining the yield and quality of the grain produced...

Grain yield was unaffected by grazing at four of eleven sites... There is growing interest in the practice of grazing crops in winter... Weed and disease pressure was measured for both grazed and ungrazed areas of each crop (data not presented ), but differences were minor...

For the purpose of this paper I am going to be concentrating on agronomic decision making or decision making around the 4R's : The right product in the right place at the right time at the right rate... What has changed recently is the ease of use of the technology and particularly the ease of handling the data that comes with use of the technologies... Getting the data off the yield monitor and then doing something with it has been one of the impediments to yield data being a more widely used management tool...

Apps and mobile devices are making it easier to collect and record data on farm.. Getting the data off the yield monitor and then doing something with it has been one of the impediments to yield data being a more widely used management tool... As smart phones and tablets become increasingly used on farm it is an obvious evolution that they become used for entering farm data on the move and should provide an opportunity to reduce time spent in the office for record keeping and compliance...

It is important to remember that there are many ways in which PA can be adopted and used to make or save money, improve timeliness or environmental management and to carry out onfarm trials... If a grower purchases a GPS unit using one system and then changes to one using the other system, locations will not be translate accurately... Growers are not confident in using the currently available indices in making cropping decisions...

Using PA you can now: zone the site using historical data such as imagery, yield, and soil type; precisely place trails using your RTK GPS; change treatments automatically using variable rate functionality in most new equipment; accurately collect 'as applied' maps to ensure the trial went on as planned; easily collect satellite imagery over the site; collect yield data to get intensive measurements of crop performance; and analyse using mapping software.. Satellite imagery of crop biomass throughout a paddock can indicate areas of difference in terms of green matter changes... Imagery and yield - Satellite imagery of crop biomass should be used to determine results of the trial compared to the rest of the paddock...

Training puts precision agriculture to work - Part 2.. At seeding, the zone is high for phosphorus (25 to 40 kilograms/ha MAP) and nitrogen (20 to 40kg/ha urea) and is where the majority of sulfur and nitrogen is top-dressed during the growing season... Zoning for phosphorus is more about saving inputs, while zoning for nitrogen and sulfur relates to building yield...
