Grain growers harvesting frosted crops this season should take extra precautions to minimise machinery wear and tear and the risk of fire, and to be conscious of the quality of grain retained for seed.
University of Western Australia (UWA) researchers have found that an enzyme in plants, ATP Synthase, plays a critical role in how plants respond to the cold.
Peter McMeekin this week foreshadows continued upward pressure on world wheat prices as Middle East and North Africa buyers continue to book business at higher levels. Haymakers in Australia taking their cue from the drought-driven hay price, while SA/Vic crop potential gets cut.
Different management options are available for frost-damaged crops, apart from cutting them for hay, which can help growers maximise the future potential of affected paddocks, according to a Western Australian agronomist.
Growers in Western Australia are advised to check their crops for frost damage following the weekend’s sub-zero events which have impacted cereal, canola and pulse crops so they can make informed choices about crop management.
Frost over recent months may have cost southern Australian croppers close to $200 million as harvest begins to reveal the full extent of the damage.
Sowing a ‘shandy’ mix of different wheat varieties into the same paddock could buffer crops against the risk of frost and heat damage later in the season.
A new tool is available to assist Western Australian grain growers determine from home whether their crops may have been affected by extreme temperature events.
The Australian Oilseeds Federation has cut its 2017/18 production estimate for the Australian crop currently in the ground by 9 per cent to 2.855 million tonnes to reflect the impact of a dry start in Western Australia, and a dry and frostbitten growing season in NSW.
Frost has impacted on the yield potential of Australia’s 2017 chickpea crop, and on winter crops generally across much of eastern Australia.
