Conteúdo: | The rhizobia and azospirilla combined use is an alternative to N-fertilizers, besides to guarantee high grain yields for the crops. In this work we evaluated the effect of on seed rhizobia and on aerial part azospirilla co-inoculation on some selected production parameters of common bean. A random block design with four replicates was used for the field experiments. The evaluated treatments were: 1- AC- Absolute control; 2- NfT- Nitrogen fertilization; 3- Rt; 4- Rt + Ab1l; 5- Rt + Ab2l; 6- Rt + Ab3l; 7- Rt + Ab4l and 8- RP- Registered product. Rhizobium tropici (Rt) was applied using 2 doses ha-1 and, Azospirillum brasilense (Ab) was applied using 1, 2, 3 or 4 doses ha-1 at V2/V3 phenological stage, while the RP treatment received two 2 ha-1 of R. tropici and 3 doses ha-1 of A. brasilense at V2/V3 phenological stage. Nodulation (nodule number - NN, nodule dry weight - NDW); growth (shoot dry weight - SDW, root dry weight - RDW) and, productive (number of pods - NP; number of grains - NG, and grain yield - GY) parameters were evaluated. The Rt+Ab3l co-inoculation provided an increase in NN, MNS, NV and NG, in addition to presenting the highest GY stability, producing about 3439 kg ha-1 as an average from the five locations, which represents an increase of 100, 93, 74 and 83 kg ha-1 in comparison to TN, PR, Rt, and TA, respectively.
