The study aimed to examine the response of cowpea Vinegar cultivarwith inoculation of rhizobia and Trichoderma spp. at cerrado environment in Gurupi – TO, in the years of 2011 and 2012. The experiment was conducted under field conditions and experimental design of randomized blocks, corresponding to the treatments: inoculation with rhizobia and Trichoderma spp. in the seed; the seed inoculation with rhizobia and Trichoderma spp. in the soil; the seed inoculation with rhizobia and Trichoderma spp. in the seed and soil; only inoculation with rhizobia; fertilized with nitrogen; and control non-inoculated and non-fertilized with nitrogen. Inoculation was performed with the rhizobia strains INPA 03-11B and UFLA 03-84. For treatments with Trichoderma spp. was used to inoculate commercial Trichoplus JCO powder formulation. The results indicated that the potential for nitrogen fixation of rhizobia strains tested, and the Trichoderma bioprotection was of fundamental importance for biomass, production, nodulation and yield, which may be related with the effective capacity to supply nitrogen and protection against pathogens. Generallythe inoculation with rhizobia and Trichoderma in the seed and soil, provided better results on the variables analyzed for both season, with higher productivity than other treatments
