OPTIMISING YIELD IN FROST PRONE PADDOCKS: Many grain growers are still
counting the cost of frost which hard hit WA's wheatbelt last season.
Although growers can't do much to manage a bad frost once it occurs, Garren
Knell, ConsultAg consultant and former GRDC frost researcher, recommends
planning ahead to minimise risk from frost events.
Mr Knell says growers should firstly identify their highly frost prone
paddocks and develop a plan to manage these areas differently.
"Growers can minimise financial exposure to frost events by investing less
in frost prone areas - using less fertiliser and lowering seeding rates and
therefore crop density, will achieve this or they can grow barley or oats
which have higher frost tolerance than wheat, but of course are not frost
"Late sowing a long season variety is another option. This can lower yield
potential in the absence of frost, but it increases the chance of avoiding
damage on high risk paddocks.
"Plan to optimise yield in low risk paddocks by sowing early with the
correct variety and using recommended inputs," Mr Knell said.
