Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 8.9%, and df for EMS = 36.
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:
May 1, 2008.
Harvested:
October 7, 2008.
Seeding Rate:
27,500 seeds/acre in 30" rows.
Soil Type:
Suches loam.
Soil Test:
P = Medium, K = Medium, and pH = 5.6.
50 lb N, 25 lb P2O5, and 125 lb K2O/acre as preplant; 153 lb N/acre as sidedress.
