    The onion Allium cepa highlights-like vegetable important socioeconomic for the country, the predominance of culture medium, small producers and the family nature, generating about 250 thousand direct jobs in production. How the culture has its phytopatological problems, the decision has been made for the economics made from the production of the largest production in production. In order to control the problems, the tests are being studied and the biological control of the main focus is the use of nematological bacteria and fungi that promote the protection of the roots of the growth, besides promoting an increase in the biomass of the plants. The use of the microorganisms may have had an important relation with the potential of soil management, cleaning of the ecosystem of systems and the suppressive. The objective of this study was to evaluate the biomass of hybrid 1205 and Serengeti crop plants grown on soils with three biological products. Three bioproducts will be tested: product 1 containing bacteria: Bacillus pumilus 1.0x10¹¹ (endospores / L), Bacillus subtilis1.0x10¹¹ (endospores / L) and Bacillus amyloliquefaciens 1.0x10¹¹ (endospores / L), Product 2 have the bacteria Azospirillum sp. 1.0x109 (UFC / dose), Pseudomonas sp. 1.0x109 (CFU / dose), Rhizobium sp. 1.0x109 (CFU / dose) and the fungus Saccharomyces sp. 1.0x109 (CFU / dose) and product 3 is a base of Bacillus subtilis1.0x10¹¹ (CFU / g) and Bacillus licheniformis 1.0x10¹¹ (CFU / g). After 60 days, morphological variables were identified as buyer of aerial and root parts, diameter of pseudocaule and bulb, weight of fresh matter and dry material and finally determined the index of galls formed not root system. The results obtained showed that the biomass concentrations between the plants cultivated in soils and with the bioproducts were concluded in comparison with the biomass among the hybrid cultivars of onion cv. 1205 and cv. Serengeti.
