Lodg.2 100 Seed Quality3 Shattering4 ------------------------------------------------------------------------------------------------- bu/acre date date in rating gm rating rating Maturity Groups VI, VI & VIII ----------------------------- A late-planted soybean trial was conducted at this location during the 1997 growing season. However, severe drought 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 have been provided to participating seed companies. ------------------------------------------------------------------------------------------------- 1. Yields calculated at 13% moisture. 2.
