"Plant Growth Promoting Rhizobacteria and Soybean [Glycine max (L.) Merr.] Nodulation and Nitrogen Fixation at Suboptimal Root Zone Temperatures." Annals of Botany 77 (1996): Discussion Conclusion The data demonstrates that cobalt sulfate and vitamin B12 were both significantly more effective than water. The presence of rhizobium did not affect plant growth. No nodules were found, no data collected. The data also demonstrates that water significantly raised germination rates for the plants. This supports the work of Gad and Kandil. Limitations –Vitamin B12 had an outlier in each trial –Human error when measuring and planting seeds –Germination rates affected the overall mean growth Cobalt Sulfate was just as effective as Vitamin B12 in stimulating plant growth. Both Cobalt Sulfate and Vitamin B12 lowered germination rates for the plants. Cobalt Sulfate is unhealthy for the microorganisms that live in the soil. The data supports the alternate hypothesis.
