1.   Yields calculated at 13% moisture.
2.   Lodging rating:  Rated 1 (all plants erect) to 5 (over 80% of plants down).
3.   Seed quality rating:  Rated 1 (very good) to 5 (very poor).
4.   Galling rating:  Rated 0 (no root galling) to 4 (76-100% roots galled).
5.   CV = 17.4% and df for EMS = 81.
6.   The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value
      was not calculated.
7.   CV = 25.1% and df for EMS = 51.
8.   CV = 17.9% and df for EMS = 62.
Bolding within each tests denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).

Jay, Florida:
Soybean Variety Performance on Peanut Root-Knot Nematode
Infested Soil, 1998, Nonirrigated

 
Maturity Groups V, VI, VII & VIII
 
A soybean trial was conducted on soil infested with the peanut root-knot nematode at this location during the 1998 growing season. However, severe drought and deer predation caused considerable variation in performance among plots within the tests. After careful analysis and review of this data, it is of the opinion of the editors that the results of this trial may not accurately reflect the performance potential of all test entries. Since this data could potentially be misleading if used in making decisions concerning variety selection, we have chosen not to present them in this publication. Results from these test will be provided upon request.
