Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 7.8%, and df for EMS = 45.
The F-test indicated no statistical differences at the alpha = .10 probability level; therefore a LSD value was not
calculated.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD
(P = 0.10).
Planted:
March 31, 2008.
Harvested:
September 1, 2008.
Seeding Rate:
30,000 seeds/acre in 30" rows.
Soil Type:
Greenville sandy loam.
Soil Test:
P = Medium, K = Medium, and pH = 6.1.
120 lb N, 80 lb P2O5, and 80 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
