* Due to forage sytems in Georgia and Florida, harvest season for rye ends on or about March 31st.
1. Rated as percent of foliage damaged by low temperature.
2. C.V. = 8.1%, and df for EMS = 69.
3. The F-test indicated no statistical difference at the alpha = 0.10 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:	October 21, 2002.
Seeding Rate:	36 seed/foot in 7" rows.
Soil Type:	Tifton loamy sand.
Soil Test:	P = Medium, K = Medium, and pH = 5.6.
Fertilization:	Preplant:	50 lb N, 50 lb P₂O₅, and 50 lb K₂O/acre.
	Topdress:	50 lb N/acre after 1st, 2nd, 3rd, 4th, and 5th harvests.
Management:	Paratilled and rototilled.
Previous Crop:	Corn.
