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...

The brochure lists the range of support currently available... 1. NEWSLETTER - State Outlook The newsletter interprets what can be confusing information into information that can be utilised by primary producers across the state to make management decisions... NOTE: The models utilised for the outputs available for subscription were developed by the Bureau of Meteorology, Department of Agriculture and Food, Western Australia and the Department of Natural Resources and Mines Queensland, Agricultural Production Systems Research Unit (APSRU) and Commonwealth Scientific and Industrial Research Organisation (CSIRO)...

In the study, a two-tiered approach was adopted to provide better long-lead seasonal forecasts for Australian grain growers... The Extreme Event Information System developed in this project needs to be further refined to enable it to indicate serious droughts such as those that developed in 2006 and 2007... Forecasting systems need to list their forecasts from the past few years prior to the crop season so farmers can assess whether they can use them with confidence...

Field work was carried out using rain-out shelters and irrigation facilities at the Department of Agriculture and Food WA's (DAFWA) Merredin Research Station (MRS) (2008 and 2009)... The distribution of rainfall had the greatest (but inconsistent) effect on yield, followed by management (row spacing)... In the long term, genetic improvements using specific traits to increase yield under dry conditions may deliver greater benefits to growers...

The treatments included harvesting the stubble for straw, standing vs. flattened stubble, and early or late control of summer weeds... Further testing would be beneficial... We encourage measurements of soil water status as these integrate the effects of all these factors...

The project has demonstrated that summer fallow management can play an important role in regulating soil moisture storage, either to reduce the risk of deep drainage, or to benefit the crop... The lysimeter experiments showed that a 4 t/ha residue cover past sowing (early and mid June) could reduce evaporation losses by approximately 10 mm in 2005 (see Fig. A2) and 15 mm in 2006... To minimise the risk of deep drainage, residue retention should be avoided as much as possible and residue loads reduced to 1 t/ha or less, unless required for other purposes (e.g. erosion control)...

Rather than buying a spader immediately, Damian set up a water repellence amelioration trial in collaboration with Dr Stephen Davies from the Department of Agriculture and Food, Western Australia... It was enough to give Damian the confidence to expand his spading program and buy his own machine - a four-metre Farmax , capable of mixing the soil to a depth of 300 to 400mm... When Ground Cover caught up with Damian in July, he was hoping for a wet August after recording just 100mm of rain at that point: "We've grown accustomed to having a good season and then a poor one," he says.

Long fallow increases soil water at sowing which in turn increases yield on good water holding capacity soils, particularly when the growing season rainfall is low (<210mm) and the summer rainfall was low (<100mm).. On good water holding capacity soils, 22-29% of years following long fallow had an average yield increase of 0.46-0.59 t/ha at Dalwallinu, 39-47% of years had an average yield increase of 0.49-0.82 t/ha in Perenjori while at Merredin 37-60% of years had a 0.51-0.76 t/ha yield increase... From other modelling work the increase stored mineral N from a fallow is 40-70 kg N/ha (Farre et al, 2012)...
