Large amounts of Bacillus spp. have been presented as strong plant growth-promoters (PGP), but most or even all of them have been isolated from soil or plants. Therefore, finding different sources and species are still significant to exploit biofertilizers applications in agriculture.

Large amounts of Bacillus spp. have been presented as strong plant growth-promoters (PGP), but most or even all of them have been isolated from soil or plants. Therefore, finding different sources and species are still significant to exploit biofertilizers applications in agriculture. The aim of this work was to study the novel strain Bacillus safensis S9, isolated from a wastewater dairy lagoon, as a potential growth promoter of soybean (Glycine max (L.) Merril) under field conditions. The first analysis carried out in small parcels showed a significant increase in dry matter at vegetative stage and a rise of 60 % in yield per plant, in S9 treated seeds in comparison to control. Also, the number of nodules per plant in S9 treatment was similar to control (in both a commercial B. japonicum inoculant was included). For the complete parcels trial a chemical fungicide was included as a new factor to compare the antifungal activity of S9. Noticeably, the S9 treatment produced a significant increase in yield, in the presence (33.9 %) or not (18.1 %) of chemical fungicide in comparison to the respective controls. In conclusion, our results suggest that the B. safensis S9 strain can be considered as a novel soybean biofertilizer compatible with commercial ones.
