Rhizobium Inoculant Comparison on Lentils

Objective

To test seed applied Rhizobium bacterial inoculants on lentils

Location: Genesee, Idaho (Rimrock area)
Annual precipitation: 20 inches per year
Rotation: Lentil, wheat
Variety: Palouse

Treatment

1. SoFast Rhizobium bacterial seed inoculant (by label directive)
2. RhizeUp Rhizobium bacterial seed inoculant (by label directive)

Comments

Both SoFast dry formula and RhizeUp liquid formula rhizobium inoculants were applied to seed as it was being placed in the planting drill. Growing conditions were ideal for lentil production at the field test site.

Data

Yield, lb/ac

Treatment	Rep 1	Rep 2	Rep 3	Average
SoFast	2600	2800	3200	2867
RhizeUp	2800	2760	3140	2900
LSD (5%)				359
CV				3.6%

Conclusion

There was no significant difference in seed yield between the two rhizobium treatments. The low CV adds additional credibility to the test results.
