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...

Higher grain yields were achieved and infection levels of blackleg reduced when commercial hybrid seed was used... Yeruga Crop Research's Trent Potter says the aim was to measure the effect of retaining hybrid sowing seed on plant vigour, internal blackleg infection, oil content and grain yield, compared with the original commercial hybrid bought from a seed supplier... Hybrid seed assessed included Conventional (Hyola 50 at all sites and Taurus at Bool Lagoon), Clearfield (45Y77, 45Y82, 46Y83 and Hyola 575CL) and triazine-tolerant (CB Tumby HT and CB Jardee HT)...

Barley Yellow Dwarf Virus can be a threat in all environments, and it is recommended that seed be treated with imidicloprid, or crops closely monitored for aphid infestation and sprayed ... In the circumstances using fertilisers that have a higher sulphur content, like MES 10 or Airseeder Superfect, can be beneficial... A fast track project was initiated to demonstrate and evaluate a range of management strategies that Twelve farms were surveyed across the western districts of southern Victoria that were considered suitable as potential trial sites based on grower and adviser recommendations...

WA guidelines sought for hybrid canola.. DAFWA senior research officer Mark Seymour says overseas research shows hybrid canola, which is a first cross produced from two parents, has the advantage of early vigour, weed competition, nitrogen efficiency and yields. ".. Farmers are discouraged from retaining hybrid canola seed due to genetic variation in subsequent generations, and retaining seed is not permitted by seed companies for RR varieties," he says...

Average yield loss of canola grown from retained hybrid seed varied from site to site, but ranged from 7 to 17 per cent when compared to the commercial hybrid sowing seed... The research showed a reduction in blackleg resistance in the retained hybrid seed but variable grain yield responses... While grain yield of CB@" Tumby HT was not significantly affected by using retained seed or mixtures compared to the commercial sowing seed, the grain yield of the mixture was similar to that of the commercial hybrid for Pioneer 45Y82, with and without Jockey , and Hyola 50 with Jockey (Table 6)...

GRDC Grains Research Update Coonabarabran, February 2014 most sites achieved those returns within 2 crop seasons after deep P application may at least partly reflect the string of wetter seasonal conditions in recent years, although the results from Jandowae, Capella and Gindie all included dry seasons in at least one of the crops followed... Overall, the performance of the barley grain only varieties showed they are capable of producing around 6 t/ha of dry matter and still yielding between 2.7 and 3.4 t/ha of grain... Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... In summary, using Yield Prophet as a way of increasing soil water knowledge is more difficult to trial than probes... In summary, the growth in the use of probes to understand soil water is easily explained using the framework above...
