The objective of this trial was to compare the performance of new soybean inoculum products on three farms in Wyandot County.

A new pre-mixed, humus-based inoculant containing a USDA-patented strain of Rhizobium with sticking agent was compared to not using any inoculant on three producer fields. Dean Koehler used 30' by 900' long strip plots. Rod Phillips and Gary Walter both used 45' by 1/2 mile long strips. The experiment design was a randomized, complete block with six replications at each site. Harvested sections of each strip plot were as follows: Koehler farm, 0.82 acre; Phillips farm, 0.30 acre; and Walter farm, 0.28 acre.
| Koehler Farm | Phillips Farm | Walter Farm | |
|---|---|---|---|
| No Inoculum Yield | 54.0 bu/acre | 65.4 bu/acre | 54.0 bu/acre |
| Inoculum Yield | 54.3 bu/acre | 65.9 bu/acre | 54.3 bu/acre |
| F test | 0.24 | 0.67 | 2.39 |
| Significance (P=0.05) | NS | NS | NS |
| CV | 1.4% | 3.0% | 3.9% |
On all three farms the inoculum treatment did not significantly increase yields. Experimental error was well controlled as indicated by low coefficients of variation.
