Darin Marti, general manager of the Farmers Co-op Association in Manhattan, says that three days into the 2013 harvest he expects the elevator to take in its largest wheat crop in 10 years. Around Manhattan, test weights average 60 pounds per bushel and farmers have yields ranging from 40 to 80 bushels per acre, with a 60 bushel average. Test weights are lighter at the co-op's Onaga and Alta Vista locations. More wheat was planted in the Alta Vista area last fall than usual, helping the elevator to take in nearly 400,000 bushels, which would be about double its annual total.
