*   This entry of Pioneer 2552 was seeded at 152 lbs/a to adjust for seed size.
     All other entries were seeded at 100 lbs/a adjusted for germination
     (eg.  90% germination = 110 lbs/a seeding rate).
**   Means within a column (i.e. Variety A vs Variety B produced with the same
      managment treatment) are considered significantly different if the difference
      between them is at least the LSD value listed at the bottom of the column.
***  Means between varieties regardless of management treatment are considered signifcantly
      different if the difference between them is at least this value.
****Management treatment averages (column averages) are significantly different if the
     difference between them is at least this value.
