“…Reports presented by Bárbaro et al (2009), Hungria et al (2013) and Hungria et al (2015) show influences on the agronomic traits of soybean crop, but the results checked by Gitti et al (2012) and , do not support the authors mentioned earlier.…”

In the last decades, the Brazilian soy productive chain has passed through a transformation process in which the yield, efficiency, profitability, economic and environmental sustainability are very important issues. In this context, the introduction of microorganisms has provided an increase in grains yield. The objective of this study was to evaluate the inoculation of Azospirillum brasilense associated with Bradyrhizobium japonicum in agronomic traits and the soybean productivity. The experiment was conducted in randomized blocks in 4 × 2 factorial, with four cultivars (Anta 82 RR ® , BRS Favorita RR ® , BRS 780 RR ® , BRS 820 RR ® ) and two treatments with A. brasilense (inoculated and non-inoculated) with three replications in two growing seasons. The following traits were evaluated: plant height, shoot dry biomass, chlorophyll content, leaf nitrogen content at flowering; and at harvest, the plant height, the insertion of the first pod, number of pods per plant, number of grains per pod, thousand-grain weight , grain yield, and grain harvest index were evaluated. There was a significant effect of growing seasons and cultivars in an isolated way and their interaction in most traits. The conditions in which the study was conducted, with or without inoculation of A. brasilense associated with B. japonicum do not affect the agronomic traits and grain yield in RR ® soybean cultivars.

“…According to Bárbaro et al (2009b), the literature reports that bacteria called PGPB (plant growth-promoting bacteria), such as A. brasilense, can act in the relationships between rhizobia and leguminous crops, promoting increments in plant growth and grain yield, in the total biologically fixed N, besides improvements in the use of N obtained by the plant through the symbiosis with rhizobium, corroborating the results found in the present study.…”

“…These effects can be due to various mechanisms, which include an anticipation in the BNF of the nodules, increment in the dry matter of the nodules, promotion of occurrence of heterologous nodulation through the increase in the formation of root hairs and secondary roots, with increment in the infection sites, inhibition of phytopathogens and production of phytohormones, besides the influences in the partition of dry matter between roots and shoots (Bárbaro et al, 2009b). In addition, as pondered by Hungria et al (2013), these effects promoted by the co-inoculation of PGPB and Table 1.…”

The use of cobalt (Co) and molybdenum (Mo) along with the co-inoculation with Azospirillum brasilense on soybean can contribute to biological nitrogen fixation (BNF), allowing higher yields. Thus, this work aimed to study the technical and economic viability of soybean in the Cerrado, according to the mode of application of Co + Mo, and seed or leaf co-inoculation with Azospirillum brasilense. The experiment was conducted in Selvíria-MS, in a no-tillage system in an Oxisol, arranged in a randomized block design with six treatments (seed application of two treatments with Co + Mo, with or without inoculation with A. brasilense, respectively; Foliar application of Co + Mo at soybean V3 stage; Foliar application of Co + Mo together with A. brasilense at V3 growth stage; Foliar application of A. brasilense at V3 growth stage; and the Control, consisting of only inoculation with Rhizobium), and four replicates. Seed application of Co + Mo associated with seed inoculation with A. brasilense promoted the highest leaf N content, hundred-grain weight, yield and profitability with the soybean crop.

“…Ainda nessa vertente, para maximização da fixação biológica de nitrogênio em soja com vistas em incrementos nos patamares de produtividade, pesquisas envolvendo a identificação de caracteres que auxiliem no processo de seleção de genótipos mais eficientes quanto a capacidade simbiótica devem ser contemplados pelos programas de melhoramento genético de soja, necessitando-se para isso, de uma maior compreensão da interação entre diferentes genótipos e bactérias envolvidas no processo (BÁRBARO et al, 2009). Ressalta-se também a necessidade de pesquisas com semelhante finalidade para a prática de co-inoculação, dada sua recente confirmação de eficiência agronômica no Brasil e que ainda se mostra com grande variabilidade nos resultados obtidos na literatura (ZUFFO et al, 2015;ZUFFO et al, 2016).…”
