Table 3. Mean dry weight yields

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 2020. Analysis included hybrid performance across a 1 yr (2020), 2 yr (2019-2020) and 3 yr (2018-2020) 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 signficiant difference (LSD) mean separation test.
