15N-isotope-enrichment determinations in field trials.
Percent Ndfa and Ndiff were calculated for Sierra Mixe varieties when Atom% 15N excess or Shoot N for the whole plant were significantly different from reference varieties as assessed by ANOVA and single-degree-of-freedom contrasts (p = 0.05), respectively. Values followed by asterisks are significantly different from the reference varieties based on single-degree-of-freedom contrasts (p < 0.05). Percent Ndfa and Ndiff were not calculated for reference (dashes). (Data at DOI: 10.6084/m9.figshare.6534545).
