LSD at 10% Level
Std. Err. of Entry Mean
1. Quality factors taken from the replicated silage trial at Tifton
2. This variable is calculated using University of Wisconsin Corn Silage Evaluation System - Milk 2000 and
reported at lbs milk/ton of dry matter (DM) and lbs milk/acre.
3. CV = % and df for EMS = .
4. The F-test indicated no statistical differences at the alpha = .10 probability lever; therefore, a LSD value
was not calculated.
5. CV = 8.3% and df for EMS = 28.
6. CV = 9.4% and df for EMS = 28.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
Planted:
April 23, 2008.
July 22, 2008.
Harvested:
Ratoon or Regrowth Crop - October 5, 2008.
Seeding Rate:
150,000 seed/acre in 30" rows.
Soil Type:
Tifton loamy sand.
Soil Test:
P = High, K = Medium, and pH = 6.2.
Preplant: 100 lb N, 45 lb P2O5, and 200 lb K2O/acre. Sidedress: 125 lb N/acre.
Fertilization:
Previous Crop: Soybeans.
Subsoiled, bedded and rototilled; Aatrex and Basagran used for weed control;
Management:
Losban used for insect control; Telone II used for nematode control.
Test conducted by A. E. Coy, R. E. Brooke, and D. G. Dunn.
