Table 3. By Location Comparison of Yield

Table 3. Location comparison of mean dry weight yields of eight corn hybrids evaluated for silage in replicated small plot trials at four REC locations in Tennessee during 2021. Analysis included hybrid performance across a 1 yr (2021), 2 yr (2020-2021) and 3 yr (2019-2021) period.

* Hybrids marked with an asterisk were in the top-performing “A” group for yield across locations within two (**) or three (***) consecutive years of the previous three-year evaluation period.
† For a full description of abbreviated biotech traits, see table 10.
‡ Hybrids that have any MS letter in common, within a column, are not significantly different at the 5% level of probability using a least significant difference (LSD) mean separation test.
