Wheat producers say the Oklahoma wheat crop is expected to double last year’s harvest of 70 million bushels.

Producers meeting at the Oklahoma Grain and Feed Association in Oklahoma City this week predicted about 140 million bushels in 2010. The average yield is expected to be 33 bushels per acre from 4.2 million acres.

North-central Oklahoma is the state’s largest wheat production region and is expected to produce nearly 42 million bushels this year. The Panhandle region is expected to produce about 24 million bushels.

Harvesting is expected to start in mid-June.
