Midville, Georgia: Corn Hybrid Performance, 1997, Nonirrigated

----------------------------------------------------------------------------------- Corn hybrid performance trials were conducted at this location during the 1997 growing season. However, soil erosion and leaching of nutrients during early growth caused considerable variation in performance among plots within the tests. 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 performance potential of all test entries. Since this data could potentially be misleading if used in making decisions concerning hybrid selection, we have chosen not to present them in this publication. Results have been provided to participating seed companies. -----------------------------------------------------------------------------------
