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...

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...

KeY POINts early planting can accelerate establishment and make full use of the growing season but can increase the risk of frost during critical growth stages and can increase the chance of crops running out of moisture before critical reproductive stages... in Australia, developmental stages are commonly referred to as 'growth stages'...

Now is the time to implement frost strategies.. Grain growers can best minimise crop losses from spring frosts by planning and implementing strategies prior to or at seeding time... "High stubble loads (greater than 2.5 tonnes per hectare) appear to increase frost damage by reducing the amount of heat radiated from the soil at night, leading to lower canopy temperatures and greater frost severity, duration and damage," he said...

International grain traders are watching markets to see what impact there will be from the world's third-largest exporter, Ukraine, announcing an eight-million-tonne drop in production after freezing temperatures destroyed large swathes of its winter crops... Then more than a third of the country's planted crop was hit by the big freeze in February that also hit much of Europe... Mr Eudall also noted that in anticipation of crops taking a weather hit, Ukraine had positioned itself to supply feedgrain markets, opening the door to Russia becoming a major supplier of quality grain to the Middle East and Asia...

Three sets of plant samples of the same variety, showing Charcoal Rot (reddish-purple-black stems), Water Stress (pale, white stems) and Full Water (healthy green stems)... Grains Research and Development Corporation (GRDC) supported research suggests that black layer (abscission layer) formation in the field is the best tool to safely schedule spray-out timing as it can help growers determine their risk approach and modify it as needed on a paddock and variety basis... When spraying, Mr McIntosh said growers needed to ensure that application was carried out in the prime time of day, usually early morning when stomates are open; ensure water quality was good, water volume adequate and adhere to seven days withholding period...
