Understanding the LSD (least significant difference)
The least significant difference (LSD) listed at the bottom of each table for each column of data should be used to determine if the difference between varieties is due to performance differences or random chance. This bulletin presents data with an LSD of 10%. If the difference between two varieties were equal to or greater than the LSD, the difference would be attributable to variety differences in 9 out of 10 (90%) instances when the two varieties are evaluated under conditions like those of the test. A difference which is less than the LSD is likely due to chance. The top performing varieties that are different due to only random chance are marked with asterisk.
