Abstract: Field experiments are carried out in the Maize Research Institute in Kneja in 2010 – 2011 in order to determine the influence of Glomus sp., Trichoderma sp., and Microbial Mix on maize hybrids Kn 435 and Kn 509. The inoculation is done by covering the seeds with the microbial products, preliminary mixed with micronized zeolite. The increase of the yield is 3 – 24% for Kn 509 and 2 – 8% for Kn 435 (2010). The most effective variants of treatment are Microbial Mix, Trichoderma 5.107, Glomus. The protein content is increased to 15% by the application of Microbial Mix, Trichoderma 5.107, Glomus sp. The lipid content of Kn 435 is not increased, while the increase of lipids in Kn 509 is up to 15.26% in the case of seed inoculation with Glomus sp. When seeds of maize FAO 400 and FAO 500 are inoculated with Trichoderma sp. and Glomus sp. and are cultivated on leached chernozem, the fertilizer rate should be increased by approximately 20%.
