1.  Yields calculated as 48 pounds per bushel at 12.0% moisture.
2.  C.V. = 6.9%, and df for EMS = 9.
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 17, 1998.
Harvested: May 19, 1999.
Seeding Rate: 15 seeds per foot in 7" rows.
Soil Type: Greenville sandy clay loam.
Soil Test: P = Medium, K = High, and pH = 6.1.
Fertilization: Preplant: 59 lb N, 54 lb P2O5, and 27 lb K2O/acre.
Topdress: 50 lb N/acre.
Management: Subsoiled twice, prebedded and bedded with rototiller.
Previous Crop: Peanut.
