Mean yields and agronomic data from Spring Hill, TN

Table A-12. Mean yield and agronomic traits of 20 full-season (>116 DAP) corn hybrids evaluated in small plot replicated trials without irrigation at the Middle Tennessee AgResearch and Education Center in Spring Hill, Tennessee during 2020. Analysis included hybrid performance over a 1 yr (2020), 2 yr (2019-2020), and 3 yr (2018-2020) period.

† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability. * Hybrids marked with an asterisk were in the top performing “A” group across locations for two (**) or three (***) years within the previous three year evaluation period. ‡ For a full description of abbreviated biotech traits, see table 17.

All yields are adjusted to 15.5% moisture.

¶ Lodging values do not typically follow a normal distribution, therefore statistical tests to compute LSD were not performed and only mean values are reported. Values highlighted in light orange are above average for a given trait, MS letters highlighted in dark orange are in the “A group”, indicating no statistical difference from the top-performing variety, for a given trait.
