frost severity

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...

Fiona Hobley (pictured with a Tiny Tag temperature logger) has tested the effects of different stubble loads on frost damage south of Nyabing, Western Australia... Paul Breust, research and extension coordinator with New South Wales grower organisation FarmLink Research, says there was an interesting development from the 2013 frosts that damaged crops in the Riverina region of southern NSW... Dr Biddulph says 2012 trials near Wickepin and York in WA showed stubble burning reduced the severity and duration of frosts...

Frost research to refine management.. National research is investigating: the influence of burning, raking, harvesting low and stubble retention on frost damage in cereals; frost responses to soil inversion by way of mouldboard ploughs and rotary spaders; the influence of crop canopy architecture on frost; and the role of grazing in delaying flowering and exposure to frost... Crop canopies have been manipulated in a variety of ways, including skip rows to create different bandwidths of crop canopies and various nitrogen and seeding rates to create different biomasses to evaluate their impact on the severity and duration of frost...

Dr Biddulph says the stubble work will build on previous research, which found that under mild frosts (canopy temperatures of -1 C to -2 C) stubble retention increased the severity and duration of frost and caused more frost damage... Crop canopies have been manipulated in a variety of ways, including skip rows to create different bandwidths of crop canopies and various nitrogen and seeding rates to create different biomasses to evaluate their impact on the severity and duration of frost...
