1.  Yields calculated as 56 pounds per bushel at 13.0% moisture.
2.  C.V. = 12.8%, and df for EMS = 24.
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).
Planted: November 20, 1998.
Harvested: May 24, 1999.
Seeding Rate: 18 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.
Previous Crop: Corn.
