The corn harvest forecast was revised upward.

Based on surveys made Sept. 1, the crop is expected to produce 8.47 billion bushels, up 2% from the forecast a month ago and 11% more than last year’s 7.66 billion bushels, the Agriculture Department reported. The department’s Crop Reporting Board said bumper harvests of some other 1985 crops also are indicated, including soybeans and cotton. Soybean production was estimated at 2.06 billion bushels, up from 1.96 billion bushels indicated in August and 11% over last year’s harvest. The cotton harvest was estimated at 13.7 million bales, down from 13.8 million bales forecast last month but 5% more than the 1984 crop.
