Reading the results
- Each result is a total dry-matter yield from a particular year, location and trial. Compare within the same trial, not across growing conditions.
- A source asterisk means the result was not significantly different from the highest numerical value using the source 0.05 LSD. It is preserved alongside the value.
- Explicitly defined BMR footnote numbers are removed from the page name; the exact source variety spelling is retained with each observation. Other spelling differences are not assumed identical.
- Commercial and experimental entries are distinguished. These are dated trial facts, not availability claims or crop-management recommendations.
Source abbreviations are expanded above. Percent signs are retained where supplied; no missing unit is invented. CV describes variation; LSD is the source’s least significant difference.
