* Values followed by the same letters indicate no significant yield
difference
Note: Rankings have been removed from the table because they didn't
reflect any statistical differences.
These trials were planted in fields which had not grown soybeans
previously. Most inoculants were applied at label rates. However,
the non-sterile peat inoculant was applied at 2X label rate.
Drought reduced yields and responses to inoculation, especially in
the Rockwood trial, this year.
Means followed by the same letter are not statistically different,
at the 5% level, from one another. Growers should choose inoculants
based on cost and convenience, as well as potential yield response.
