South Australia's grain harvest for 2012-13 will be worth almost $2 billion on export markets.
Primary industries SA says the harvest is almost complete and is set to come in at 6.45 million tonnes, above initial expectations.
Grains account manager Dave Lewis said the better than forecast crop had offset easing grain prices, maintaining the value of the harvest to the state economy.
"All districts, except for the later finishing areas completed harvest by the end of December, with crops in some areas performing above expectations given the below average rainfall," he said.
Mr Lewis said the better than expected crop production performance had offset the lower value as grain prices dropped, maintaining farmgate value of the crop at $1.5 billion.
"SA's grain industry contributes up to $4.6 billion to the State's economy, with about 80 per cent of our grain exported around the world," he said.
Information from PIRSA shows many parts of the state recorded close to average yields for cereals, while the Western Eyre Peninsula, the Upper North and parts of the Mallee were affected by frost.
Hay quality has generally been very good with minimal weather damage.
