      Droughts in the Midwestern corn belt pushed up demand and prices for corn nationwide, but those droughts did not affect southeast Arizona. Rainfall increased; in some locations in Cochise County, rains nearly set a record. High moisture during July helped pollination and pushed Arizona growers into the limelight with a first and a third place win in the National Corn Growers yield trials. The national winner was Ted Johnson, with a yield of 253 bushels per acre (14,168 pounds per acre) (1, 2).

      Eleven corn hybrids were grown for silage in Greenlee county in 1988. Excellent yields were recorded; the top hybrid, Northrup King's S 8505, produced nearly 40 tons per acre at 70% moisture. Laboratory analyses were run on samples from each hybrid; these analyses, plus calculations of crude protein and energy per acre were made.

      DeKalb 656 and a new Northrup King hybrid, NK 7759, were the leading hybrids in both yields and adjusted gross income per acre. However, yields were lower than anticipated. The top yield was 8161 pounds per acre, providing an adjusted gross income of $480.30 per acre.
