Relationship between N stress level, as determined by NNI at R1, and the percent change in stover dry matter from R1 to R6 (%PostStover DM) across maize genotypes in the Old and New Eras. Different letters signify LSMeans within Eras (Old or New) are significantly different across N stress levels. An *denotes a significant difference between the Old and New Era LSMeans within a given N stress level. *denotes significance at the 0.05 probability level.
