Table A-6. Mean yields and agronomic data from Springfield, TN Irrigated

Table A-6. Mean yield and agronomic traits of 15 full-season (>116 DAP) corn hybrids evaluated in small plot replicated trials with irrigation at the Highland Rim AgResearch and Education Center in Springfield, Tennessee during 2021. Analysis included hybrid performance over a 1 yr (2021), 2 yr (2020-2021), and 3 yr (2019-2021) period.

† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability. * Asterisks after a hybrid name indicate the number of preceding consecutive years in the top-performing “A” group. ‡ For a full description of abbreviated biotech traits, see table 18. § 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.
