BECQUER, C. J. et al. Effect of the inoculation with rhizospheric bacteria and Trichoderma in wheat (Triticum aestivum L.). Pastos y Forrajes [online]. 2015, vol.38, n.1, pp.29-37. ISSN 0864-0394.

A trial was conducted in greenhouse to evaluate in wheat the effect of the inoculation with the rhizobacteria Sinorhizobium meliloti, Azospirillum zeae and Azospirillum canadense, and with the fungus Trichoderma harzianum. The experimental design was completely randomized, with four replications and five plants per treatment. A treatment fertilized with NH4NO3(150 ppm/kg of soil), an absolute control and 13 inoculated treatments, were used. The aerial dry weight, root dry weight, stem length, germination and content of leaf chlorophyll were evaluated. The separate application of Trichoderma had a positive effect on stem length (5,58 cm), but its presence in some combinations with rhizospheric bacteria was not positive and at the moment of sowing, or afterwards did not show uniform results in the variables. Nevertheless, the treatment Trichoderma + NRG34-DS2 5d stood out in the root dry weight (0,45 g/plant) and the aerial dry weight (0,58 g/plant); as well as the treatment A2-N7, in the chlorophyll content (40,35 SPADS/plant) and stem length (5,50 cm). It is concluded that the simple application of Trichoderma did not exert a positive effect on most variables, and none of the treatments positively influenced germination. It is recommended to evaluate Trichoderma + NRG34-DS2 5d and A2-N7 in field experiments.
