Oats underpin mixed-farm management.. A farming family from Condobolin in central New South Wales is endeavoring to turn every drop of rain into grain, with opportunity oat crops providing management flexibility.. James (left) and Graham McDonald and their family grow Yarran oats on their properties near Condobolin, New South Wales...

When sowing to wheat or another cereal in a paddock with a previous history of Rhizoctonia bare-patch, using cultivation below the seed (~10 cm) and a registered fungicide can reduce disease impact... A break crop of canola or a chemical fallow may be useful for reducing Rhizoctonia inoculum in the soil prior to sowing a cereal crop... EverGol Prime and Vibrance have been evaluated as seed treatments to suppress Rhizoctonia in field trials conducted by DAFWA and SARDI in 2011 and 2012 (Table 1)...

Growing break crops in a well-managed way can significantly and consistently boost the yields and profits of subsequent wheat crops in good seasons and reduce overall farming risks... Dr Lawes said an analysis of 30 years of data from across the WA grainbelt using the crop and economic modelling systems APSIM and LUSO indicated there was a 0.6 tonne per hectare average yield benefit in wheat crops grown after a lupin break crop and 0.4t/ha benefit following canola, compared with wheat grown after wheat... "We found the first wheat crop in a continuous wheat sequence could increase costs and depress yields in the second and third year wheat crops and reduce the probability of these subsequent wheat crops making a profit," he said...

Crop sequences will continue to be an important part of profitable and sustainable cropping systems in WA. Research conducted in this project showed the potential for substantial improvements in the profitability of crop rotations if break crops were used more widely... The new insights about the value of break crops in profitable crop rotations and the revised assumptions to the MIDAS model have been used to improve new models being developed by the CSIRO and DAFWA (the Land Use Sequence Optimiser (LUSO) and Leap economic models, respectively)... For example, there had been no research into the break crop effects of oaten hay in WA and one of the most common rotations on WA farms - lupin/wheat/canola/barley - had not been examined...

" Integrated disease management in northern no-tillage systems using precision agriculture.. Whilst progress is being made using traditional methods of disease management (e.g. varieties, crop rotation, fungicides), precision agriculture (PA) has the potential to provide growers with a tool to rapidly and cost effectively reduce the impact of diseases... Separating next year's crop from last year's stubble has been considered a control option for some diseases and precision agriculture offers the potential for this to be achieved < Keep browsing..

As a consequence of the project UA00060, vital information has been obtained on the seedbank ecology and population dynamics of brome in response to various management strategies developed through on-farm research... Results from the survey of grower paddocks on Yorke (YP) and Eyre Peninsulas (EP) in South Australia (SA) confirmed the species of brome grass infesting cereal crops of southern Australia as Bromus diandrus and Bromus rigidus ... Several studies were undertaken at Roseworthy to investigate the germination behaviour of different populations of brome grass ( B. diandrus and B. rigidus ) collected from sites on YP and EP. Clear differences were shown between species, with populations of B. diandrus germinating at a much faster rate than its close relative, B. rigidus ...

Caption: DAFWA research officer Martin Harries says the GRDC-funded Focus Paddock project in WA has identified no adverse wheat productivity impacts of expanded canola plantings at the expense of legumes in crop and pasture sequences... In the northern region, two years of cereals-one year of lupins-one year of canola had an average GM of $280/ha.. Rotations with two years of canola and two years of cereals (W-C-W-C) were popular in the southern agricultural region and had an average GM of $340/ha..
