1.  Yields calculated as 60 pounds per bushel at 13.5% moisture.
2.  C.V. = 9.7%, and df for EMS = 135.
3.  The F-test indicated no statistical difference at the alpha = 0.1 probability level; therefore an 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).

Harvested:   May 24, 1999.
Seeding Rate:   22 seeds per foot in 7" rows.
Soil Type:   Tifton loamy sand.
Soil Test:   P = Medium, K = Medium, and pH = 5.6.
Fertilization:   Preplant:   40 lb N, 40 lb P2O5, and 40 lb K2O/acre.
    Topdress:  65 lb N/acre.
Management:   Moldboard plowed and rototilled.
