“…J. Fernandes et al (2021b) also recorded a higher total biomass for upland rice co-inoculated with Ab-V5 + BRM 63573. Similarly, Braga et al (2018) showed that soybean inoculation with Bacillus subtilis increased shoot and root dry biomasses.…”

“…They can provide greater root diameter of seedlings (J. P. T. Fernandes et al, 2021a) and higher biomass production (J. Fernandes et al, 2021b) in upland rice plants, compared to the control treatment (without rhizobacteria). Other studies have also shown that more than one multifunctional rhizobacterium can be inoculated into plants using a technique called co-inoculation (M. A.…”

A inoculação e coinoculação do arroz de terras altas com rizobactérias multifuncionais pode promover o crescimento das plantas, especialmente do sistema radicular. Assim, este estudo teve como objetivo avaliar o efeito da inoculação e coinoculação com Azospirillum sp. e Bacillus sp. no desenvolvimento inicial do arroz de terras altas. O experimento foi conduzido em delineamento inteiramente casualizado com 4 tratamentos e 10 repetições, totalizando 40 parcelas. Os tratamentos foram: 1) Ab-V5 (Azospirillum brasilense), 2) BRM 63573 (Bacillus sp.), 3) coinoculação de Ab-V5 + BRM 63573 e 4) controle (sem rizobactérias). A inoculação e coinoculação com as rizobactérias multifuncionais Ab-V5 e BRM 63573 proporcionaram efeitos positivos no desenvolvimento inicial do arroz de terras altas. A inoculação com o isolado BRM 63573 teve efeitos significativos no comprimento da raiz, parte aérea e biomassa total, enquanto a inoculação com o isolado Ab-V5 teve efeitos significativos no comprimento da raiz e produção de raiz e biomassa total. O tratamento com coinoculação teve efeitos significativos em variáveis como diâmetro, volume e superfície total de raiz e biomassa de raiz e total. O tratamento controle (sem rizobactérias multifuncionais) apresentou os piores resultados para a maioria das variáveis analisadas.

“…Recent studies show the beneficial effects of multifunctional microorganisms in increasing shoot dry biomass and productivity of soybean (SILVA et al, 2020b;CHAGAS JUNIOR et al, 2022) and common bean (Phaseoulus vulgaris) (REZENDE et al, 2021a); growth promotion of rice (Oryza sativa L.) (FERNANDES et al, 2021;PARRALES et al, 2022) and accumulation of N in maize plants (Zea mays) (MORENO et al, 2021). In addition, the use of different beneficial microorganisms at the same time, defined as coinoculation or consortium of microorganisms, has been gaining market share, since it adds different mechanisms of action, producing potential synergistic effects, compared to the use of isolated microorganisms (FLAUZINO et al, 2018).…”

The use of multifunctional microorganisms (MM) directly benefits the growth and development of plants due to the production of phytohormones and siderophores, supply of nutrients, and assimilation of atmospheric nitrogen (N2), as well as, indirectly, by protecting plants against pathogens. In this way, the search for sustainable agricultural systems is of great importance in searching for cultivation technologies that provide productive increments and minimize production costs and negative environmental impacts. The study aimed to determine the effect of multifunctional microorganisms on gas exchange, grain yield, and production components in soybean plants. In the field experiment, 2019/2020 harvest, a randomized block design was used, with 32 replications. Soybean plants were treated with a consortium of microorganisms Serratia marcensens (BRM 32114) + Bacillus sp. (BRM63573), and, as a control, soybean plants were treated without intercropping. Soybean plants treated with microorganisms showed an increase in photosynthetic rate (16.65%), stomatal conductance (37.50%), the internal concentration of CO2 (10.36%), a mass of 100 grains (4.04%), and yield of grains (14.83%) about untreated plants. Therefore, using a consortium of multifunctional microorganisms, combining multiple functionalities from different microorganisms, shows the potential to increase the agronomic performance of soybean plants. Co-inoculation technology appears as a strategic component of achieving sustainable agriculture.
