One experimental hybrid, DKC 37-38, with a Goss’s wilt rating of 7 out of 9 (“poor”), was planted at the University of Nebraska Agricultural Research and Development Center (ARDC) near Mead, NE on 2 Jun. Corn was planted at 32,000 seeds per acre in a field that received minimum tillage. The previous year’s crop was corn. Each plot was 30 ft long and contained two rows spaced 30-in. apart. Alleys were cut between plots reducing plot length to 28 ft. All plots were irrigated with an overhead sprinkler center pivot irrigation system. . . . There were no significant differences observed within the AUDPC between the treated and nontreated plots. There were also no significant differences exhibited in yield between the treated and nontreated plots. The 2012 growing season was extremely hot and dry. Low yield may be due to temperatures exceeding 100°F between growth stages VT-R2.
