Utah's onion farmers expect to harvest 64.8 million pounds of onions this year, 21 percent below last year's record harvest but 38 percent above the 1986 production, according to the Utah Agricultural Statistics Service.

Farmers expect to harvest 1,800 acres of onions, up 100 acres from 1987 and 400 acres above the 1986 tally. Yields are forecast at 36,000 pounds per acre, 12,500 pounds less than last year but 2,500 pounds above the 1986 yield.State Statistician DelRoy J. Gneiting said early harvested fields are yielding smaller-size onions than a year ago, primarily due to heat stress.
