Table 4-a. East Tennessee (Knoxville) Yield and Agronomic Traits

Table 4-a. By location mean yield and agronomic traits of eight corn hybrids evaluated for silage in small plot replicated trials at the East Tennessee AgResearch and Education Center in Knoxville, Tennessee during 2021. Analysis included hybrid performance over 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.
