Stoller Corn Study
W. Albus, R. Dodds, L. Besemann and H. Eslinger
MATERIALS AND METHODS
Soil: Maddock sandy loam, Hecla sandy loam and Embden sandy loam; pH = 7.1; 1.7 % organic matter, soil N 27 lbs/acre soil K were very high; soil S was high.    
Previous crop: 2012 – soybean.      
Seedbed preparation: Spring conventional tillage.    
Planting: May 17, DeKalb DKC-49-29 in 30-inch rows.  
Plots: Plots were 40 ft long by 10 ft (4 rows) wide.  The study had six replications.
Treatments: Trt 1 = check; trt 2 = Bio-Forge 16 oz/acre @ V6 (June 25); trt 3 = Bio-Forge 8 oz/acre @ V6 (June 25) and Bio-Forge 8 oz/acre @ R1 (July 31); trt 4 = check;         trt 5 = Bio-Forge 8 oz/acre in-furrow @ planting (May 17), Bio-Forge 8 oz/acre @ V6 (June 25) and X-Cyte 16 oz/acre; V9 (July 8); trt 6 = Bio‑Forge 8 oz/acre in‑furrow @ planting (May 17), Bio-Forge 8 oz/acre @ V6 (June 25), X-Cyte 16 oz/acre; V9 (July 8) and Sugar Mover 16 oz/acre @ R1 (July 31).    
Fertilizer: Broadcast 9 lbs N/acre, 42 lbs P2O5/acre, 36 lbs K2O/acre, 5 lbs S/acre and 2 lbs Zn/acre.  Three lbs N/acre and 10 lbs P2O5/acre in furrow as 10-34-0 May 17.  Stream bar 60 lbs N/acre May 25 and side dress 180 lbs N/acre as 28-0-0 June 25.      
Irrigation: Overhead sprinkler irrigation as needed.    
Pest control: Outlook (18 oz/acre) May 23, 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, 36 feet long.
