| The table below summarizes,
by species, five years of crop average yield and germination
information. The table provides seed planning professionals
with an understanding of yields (in kg/hL), germination
capacity (GC), and germination values (GV) that can
be expected for each species. This table also shows
the degree of variation between crop years for each
species.
