| 1A comparison cannot be made at Ardmore for the 1992-1993, 1996-1997, and 2000-2001 seasons. In 1992-1993 the grain yield for early plantings was not taken because of ryegrass infestation. The late test was not planted in the fall of 1996-1997 because of wet conditions. The late test was not planted at Ardmore or Burneyville in the fall of 2000 because of prolonged dry conditions in September and October. |
