Co-inoculation of soybeans and common beans with rhizobia and azospirilla: strategies to improve sustainability

Inoculation with Bradyrhizobium sp. and Azospirillum brasilense Associated with Application of Cobalt and Molybdenum on Nutrition and Soybean Yield

“…Seed inoculated with A. brasilense and seed application of Co and Mo provided higher mass of 100 grains and grains yield of soybean, with an increase of 1007 kg ha -1 of grain, equivalent to 18.4% more than the control (only inoculated with rhizobia), corroborating with Hungria et al [15] showing that co-inoculation with A. brasilense increased yield of soybeans in 16.1%…”

“…Increases in total nitrogen biologically fixed by plant through symbiosis with rhizobia, associated with A. brasilense, have also been reported in other researches [24,15]. However, Zuffo et al [30] observed that the use of A. brasilense alone or in co-inoculation with B. japonicum does not have significant effect on leaf N concentration.…”

“…Yet, pondering Hungria et al [15], these results caused by co-inoculation bacteria promoters of plant growth and Rhizobia appear to be Means followed by the same letter in the column do not differ by the Tukey test at 5%. CV: coefficient of variation; LSD: least significant difference.…”

“…Considering the main current limitations and potential of BNF in soybean crop and benefits attributed to various crops by inoculation with Azospirillum brasilense (diazotrophic bacteria with free life), with emphasis on larger development of the root system and consequently greater absorption of water and nutrients, we can infer that co-inoculation with both the microorganisms can improve the crop performance in an approach that meets the current demands of agricultural, economic, and environmental sustainability [15].…”

Modes of application of cobalt, molybdenum and Azospirillum brasilense on soybean yield and profitability

“…Considering the main current and potential limitations of BNF in the soybean crop and the benefits attributed to the various crops by the inoculation with Azospirillum (free-living diazotrophic bacteria), especially the greater development of the root system and, consequently, also higher absorption of water and nutrients (Galindo et al, 2016), it is deduced that, with the co-inoculation in microorganism, there may be improvements in the performance of the crops in an approach that respects the current demands for agricultural, economic, social and environmental sustainability (Hungria et al, 2013).…”
