1. IVDMD (in vitro dry matter disappearance) is an indicator of quality and is positively related to animal digestibility (higher values indicate higher digestibility). Samples used for IVDMD determination were
collected for all entries of a replicated trial at the same state of reproductive development (soft dough).
2. CV = 23.0% and df for EMS = 24.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10).
Planted:	June 21, 2001.
Harvested:	September 27, 2001.
Seeding Rate:	125,000 seed/acre in 30" rows.
Soil Type:	Cecil sandy clay loam.
Soil Test:	P = High, K = Medium, and pH = 6.6.
Fertilization:	Preplant: 49 lb N, 98 lb P₂O₅, and 147 lb K₂O/acre. Sidedress: 125 lb N/acre.
Previous Crop:	Soybean.
Management:	Chisel plowed, disked, and rototilled; Aatrex and one cultivation used for weed control; irrigated 4.0 inches.

Test conducted by P. A. Rose.
