† Varieties that have any MS letter in common are not significantly different (Fisher’s Protected LSD, P<0.05). Mean separation letters are highlighted in dark orange for values that are not statistically different from the highest value across all entries within a given trait. Mean values between the 50th and 75th percentile are highlighted in light orange, mean values above the 75th percentile are highlighted in dark orange. § For analysis, values transformed using (value)^2 due to non-normal distribution. Untransformed means and summary statistics are reported. ‡ For analysis, values transformed using log (value+1) due to non-normal distribution. Untransformed means and summary statistics are reported. ‡‡ Non-normal distribution, means reported ¶ Analyzed using near infrared spectroscopy (NIRS) with the appropraite calibration for each species. Reported on a 100% DM basis. †† Estimated using quality constituents from NIRS inputted into the UGA cover crop nitrogen calculator.
