Table 3. Mean dry weight yields

Table 3. Mean dry weight yields across and by location of 13 corn hybrids evaluated for silage in replicated small plot trials at four REC locations in Tennessee during 2018. Analysis included hybrid performance across a 1 yr (2018), 2 yr (2017-2018), and 3 yr (2016-2018) period.

* Hybrids marked with an asterisk were in the top performing “A” group for yield within two (**) or three (***) consecutive years of the previous three year evaluation period.

† For a full description of abbreviated biotech traits, see table 5.

‡ 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.
