Table showing the predicted flowering dates in three regions using the Flowering Calculator.. The successful adoption of this strategy hinges on matching variety to sowing time to maximise growth and to minimise the likelihood of frost damage after flowering - and also to minimise the impact of hot weather and terminal drought during grain fill... The Flowering Calculator is a tool that enables an adviser or grower to compare flowering dates relative to the risks of frost and the likelihood of experiencing water stress during grain development...

With frost damage now estimated to be costing growers $360 million a year, the Australian National Frost Program (ANFP) is broadening its assault on the issue... Dr Juttner says methods varied across the country, so the results could not be compared... Dr Juttner says the method ANFP researchers have now developed involves staggered times of sowing, so that when a frost event hits they can tag individual heads of different wheat and barley varieties, at the same stage of development - in other words, they can compare the effect of frost on different cultivars at a synchronised developmental stage and compare like with like...

Dr Phil Davies from SARDI checks the performance of field pea plants in a trial at the University of Adelaide's Waite campus in South Australia... "The heat-stress tolerance is due to several genes dispersed across the genome - a situation that makes it difficult to breed all genes into elite cultivars without the genes becoming separated during the genetic recombination that occurs during sexual reproduction," Dr Davies says... Dr Davies has found there is sufficient interest in the trait to pursue molecular markers, which may provide a viable way to rapidly select for these heat-tolerance genes using a cost-effective DNA typing technology favoured by breeders...

Harvest is crunch time for each year's crop, and always a good opportunity to evocatively capture on film the season's end-game.. Harvester at night in fields with moon shining through clouds... In the areas, growers suggest that early sowing, good winter rains and newer wheat varieties, such as LongReach ScoutA and Mace, have all contributed to the production achieved, despite receiving only 40mm of spring rain...

Plan ahead to stop canola stem rot.. Clean or grade any retained canola crop seed from last season that shows signs of sclerotinia - or use new, clean seed... Dr Khangura says use of fungicides will be determined by: disease presence; conditions conducive for disease development (including rainfall and crop biomass levels); maturity of the variety; crop yield potential; and canola prices...

A national network of demonstration sites, co-ordinated by key farm groups (owned and driven by farmers) in each State working in conjunction with State Agencies and CSIRO, will examine new and alternative strategies for farmers in the Australian broadacre wheat/sheep zone to mitigate the negative effects and capitalise on the opportunities of climate change on their production systems... The farm groups are uniquely situated to, not only demonstrate new practices, but also to bring awareness of the impacts of climate change and adaptations required to ensure continuing farm viability... Farmers in the dryland wheat-sheep zone will have greater awareness of the likely impacts of climate change on their production systems and are in a better position to develop practices which mitigate the likely negative impacts of climate change on their enterprise viability...

The objective of the national demonstration initiative is to establish a network of farms to demonstrate strategies for grain farming systems that address adaptation to climate change impacts... As a consequence: - Farmers and advisers have direct access to, and learning from, on-ground demonstration of new and existing, locally-relevant adaptations to climate change to maintain or enhance farm viability.- Rapid dissemination of meaningful and believable messages on adapting to climate change to their local communities.- Assessment of the emission implications of the demonstrated different adaptations using existing National Greenhouse Gas.. In collaboration with grower groups (including Facey, Liebe, North Mallee Farm Improvement Group and WANTFA), the Department of Agriculture and Food Western Australia (DAFWA) has planned a network of farms demonstrating climate risk management strategies across the central WA wheatbelt in 2011...

Workshops to help growers combat frost.. Farmers can find out by attending Grains Research and Development Corporation (GRDC) Pre-Seeding Frost Workshops in March... "Other expert speakers will include Ben Biddulph and Ian Foster (DAFWA), Steven Crimp (CSIRO), Rebecca Jenkinson (Living Farms) and Steve Curtin (ConsultAg)," he said...

Advice concerning the significance and control of the more common pests, or potential pests, of these crops is presented... Value of the crop (high value crops cannot sustain too much damage as a small loss in yield or quality could mean a large financial loss), the cost of the spray and its application and the likely yield or quality benefit gained from control... Crop monitoring Ongoing monitoring of crops and surrounding vegetation is essential to determine the presence of both pests and predators, and when, if any, intervention is required to keep pests at an acceptable level or, if feasible, boost predator numbers by introducing them into the system...
