Mosaic Corn Study
K. Mann, W. Albus, R. Dodds, L. Besemann and H. Eslinger
MATERIALS AND METHODS
Soil: Maddock sandy loam; pH = 7.1; 2.4 percent organic matter; soil N 36 lbs/acre; soil P and soil K were very high; soil S was high.
Previous crop: 2012 - soybean.
Seedbed preparation: Spring conventional tillage.
Planting: May 16, DeKalb DKC-49-29 in 30-inch rows.
Plots: Plots were 40 ft long by 15 ft (6 rows) wide.  The study had four replications.
Fertilizer: Broadcast and incorporated treatments (see treatments in table 1) May 14, May 15 and June 10, stream bar 60 lbs N/acre as 28-0-0 May 25 and sidedress N as 28‑0-0 June 24 to all treatments except # 1 to bring the total N applied to 180 lbs/acre.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Outlook (18 oz/acre) May 31, Laudis (3 oz/acre) + Roundup Power Max (40 oz/acre) + AAtrex 9-0 (0.5 lb ai/acre) + Destiny (0.05 %v/v) + AMS (1½ lb/acre) June 11.
Harvest: November 5 with a plot combine.  Harvest area was the center two rows, 37 feet long.
