Table 6-a. Middle Tennessee (Spring Hill) Yield and Agronomic Traits

Table 6-a. By location mean yield and agronomic traits of eight corn hybrids evaluated for silage in small plot replicated trials at the Middle Tennessee AgResearch and Education Center in Spring Hill, 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.

  • Based on University of Wisconsin Milk2006 software program.
    ‖ ANOVA was not performed for lodging, mean values are given.
