CHICAGO, Nov 6 (Reuters) - Persistent rains have lead to the latest harvest in more than 20 years, but the U.S. soybean crop is still expected to be the largest on record and U.S. corn the second largest, analysts said ahead of a government report next week.
The U.S. Agriculture Department is expected to slightly increase its soybean crop estimate and lower its corn estimate when it releases its monthly report at 8:30 a.m. EST (1330 GMT) on Tuesday.
On average, analysts forecast U.S. soybean production at a record 3.262 billion bushels, up from USDA's October forecast for 3.250 billion. The corn crop is pegged at 12.940 billion, below the government's previous forecast for 13.018 billion but still what would be the second-largest crop ever. [ID:nN05438520]
