Abstract: The influence of the products Voodoo Juice (VJ) and Tarantula (TRL), containing rhizospheric bacteria Bacillus sp. on maize hybrids Kn 435 and Kn 509 is determined in the Maize Research Institute in Kneja in 2010 – 2011. The yield is increased by 1 – 6% for Kn 509 and by 0 – 14% for Kn 435 after treatment with VJ. The yield of Kn 435 isn’t increased by TRL treatment, while the yield of Kn 509 is up to 12% higher. The inoculation of seeds of the earlier hybrid with the tested products has no significant effect on grain quality. The protein content of Kn 509 is increased up to 17% when the seeds are treated with VJ and up to 14% when treated with TRL. The lipid content of Kn 509 has an average increase of 11% and 15.53% when the seeds are treated with VJ and TRL respectively. The results show the TRL Bacillus strains have stronger positive effect than the VJ strains.
