This article presents the results of soybean implantation when microorganisms were incorporated during the sowing period and under field conditions. The microorganisms evaluated were three isolates of Trichoderma sp, three isolates of Bacillus and one isolate of Gliocladium roseum. A treatment with fungicide and an untreated plot were incorporated and therefore nine treatments were performed. The effects were evaluated by registering the number of emerging plantlets and the number of plants at harvest, measuring the height of plants, registering the yield components and the plot weight. In average, plots treated with Trichoderma (HT3) emerged in a higher extension. Important interaction between the treatments and the assays was shown. The treatment with Trichoderma (HT3) obtained greater number of plants that reached the harvest stage. Among the Bacillus, B8 isolation showed a good behaviour in two of the tests.

Keywords : Biocontrol; Soybean; Trichoderma sp.; Bacillus sp.
