* 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.
