Oat. Tifton, Georgia: Oat Grain Performance,

Transcription

1 Oat Tifton, Georgia: An oat variety grain trial was planted at this location on September 23, However, crown rust disease and lodging during the growing season resulted in some very low grain yields and considerable variation in performance within and among plots in the test. After careful analysis and review of the data, it is the opinion of the editors that the results of this trial may not accurately reflect the genetic performance potential of all the test entries. Since this data is not useful for making decisions and could be misleading if used in making variety selections, it will not be presented in the publication. AP Small Grain Performance Tests
