frost damage

From the farm to the lab to take on frost.. "I saw the job as an opportunity to better understand frost and work on research investigating options for managing it," Brenton says... While the results of the first year of research are being analysed, Brenton says working on a frost research project has opened his eyes to a wider range of career opportunities within the grains industry and allowed him to build more extensive industry networks...

The Australian National Frost Program (ANFP) was established in 2012 by UA, DAFWA and GRDC. Frost sensitivity ratings are being developed for current wheat and barley varieties to assist growers manage the risk of frost... Reductions in grain number start to occur in wheat and barley when canopy temperatures at flowering are around 0 and -2 C respectively with no visible signs of frost damage... Canopy temperatures at flowering below -4 C and -6 C in wheat and barley respectively can cause major crop losses...

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...

In summary VSAP is: A summary of the key reasons for the release of the new variety, including strengths and weaknesses, and how the new variety should be managed relative to current common varieties... Overall, Total N fixed was strongly linked to dry matter production and rainfall... Overall, early removal is still likely to be the best option on heavy clay soils...

The proportion of the total seasonal water use which is used by a crop after flowering goes a long way to determining the yield and quality of the grain produced... The management plan has to cater for the variation between seasons that occurs, and requires flexibility... Growers need to investigate their soils for themselves...

nortHern region Balancing the risk for wheat the optimal sowing date results in wheat flowering after the last frost but before heat stress events begin... 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...
