1. Percentage of cotton lost to wind and rain.
2. The F-test indicated no statistical differences at the alpha = .10 probability level, therefore a LSD value
was not calculated.
Bolding indicates entries not significantly different from highest yielding entry based on Fisher's
protected LSD (P = 0.10).
