LSD at 10% Level
Std. Err. of Entry Mean
1. CV = 9.4% and df for EMS = 27.
2. CV = 11.0% and df for EMS = 27.
3. The F-test indicates no statistical differences at the alpha = .10 probability level; therefore, a LSD
value was not calculated.
4. CV = 16.5% and df for EMS = 27.
5. CV = 14.3% and df for EMS = 27.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's
protected LSD (P = 0.10).
Planted:
April 18, 2007.
Harvested:
July 11, 2007.
Ratoon or Regrowth Crop: September 13, 2007.
Seeding Rate:
150,000 seed/acre in 30" rows.
Soil Type:
Tifton loamy sand.
Soil Test:
P = High, K = Medium, and pH = 6.0.
Preplant: 50 lb N, 0 lb P 2O5, and 97 lb K 2O/acre.
Fertilization:
Sidedress: 100 lb N/acre, plus 50 lb N after 1st harvest.
Previous Crop: Soybean.
Subsoiled, bedded, and rototilled.
Management:
Test conducted by A. E. Coy, R. Brooke, and R. Jackson.
