“…This demonstrates that, under this condition, the presence of Azospirillum brasilense did not interfere with this trait. These results corroborate the studies by Braccini et al (2016) and Zuffo et al (2016), who worked with the application of Azospirillum brasilense and Bradyrhizobium japonicum in soybean and found no difference in the mean yield between inoculated and co-inoculated treatments.…”

This study aimed to verify the effect of co-inoculation, association between Azospirillum brasilense and Bradyrhizobium japonicum bacteria, on soybean plants subjected to water deficit at two sowing dates. Two field experiments were conducted at the Universidade Federal de Tocantins, campus of Palmas, Brazil, in 2016. The experimental design was randomized blocks in a split-split-plot arrangement with four repetitions, where the plots consisted of two irrigation depths (100 and 25% of crop evapotranspiration - ETc), the subplots was composed of two methods of inoculant application (inoculation with Bradyrhizobium japonicum and co-inoculation with Azospirillum brasilense + Bradyrhizobium japonicum) and the sub-subplots comprised two soybean cultivars (TMG 132 and ANTA 82). The cultivars responded differently to the sowing dates. Co-inoculation did not influence grain yield under full irrigation conditions (100% ETc), in neither cultivar evaluated. However, under the water deficit condition (25% ETc), the grain yield of the cultivar TMG 132 increased 77.20%, indicating that there are different responses of interaction between Azospirillum brasilense, plant genotype and sowing dates.

“…The lack of a significant effect of the use of A. brasilense on the parameters, first pod insertion height, plant height and N foliar content can be attributed to the efficiency of B. japonicum bacteria in atmospherical N fixation within the root nodules, and in competition with the other bacteria, including the genus Azospirillum (Zuffo et al, 2014). Thus, it appears that the use of co-inoculation did not influence these two variables, indicating the non-influence of Azospirillum on the action of Bradyrhizobium.…”

Background. The use of microorganisms in agriculture, such as Bradyrhizobium japonicum and Azospirillum brasilense and soybean cultivation together with nitrogen fertilization, may be interesting alternatives to increase crop yield. The soybean with the use of Azospirillum brasilense, together with Bradyrhizobium bacteria, in a current approach aimed at agricultural, economic, social and environmental sustainability. Objective. To evaluate the influence of the application of different doses of Azospirillum brasilense on co-inoculation with Bradyrhizobium japonicum in the soybean crop, in the first and third year of cultivation. Methodology. The experiment was carried out in the municipality of Alta Floresta - MT, Brazil, in the harvest of 2016/2017. The treatments consisted of the combination of four doses (0, 2, 4, 8 mL kg-1 of seeds) of the commercial product Nitrogeo AZ®, composed of Azospirillum brasilense, with 4 replicates. For the standard inoculant the commercial product Nitrogeo Soja Turfa® was used Bradyrhizobium japonicum, with a dose of 3.2 g kg-1 of seeds. Height of first pod insertion, plant height, number of pods per plant, mass of one thousand grains, productivity and leaf content of nitrogen were analyzed. Results. There was an increasing in both grain yield and thousand grains weight in the treatments with Azospirillum brasilense. Higher plants with a higher number of pods were found in the area of the 3rd year of cultivation, compared to the area of the 1st year, however, the co-inoculant doses did not influence this variable. The highest grain yield was obtained with the use of 338 mL of commercial product per 50 kg of seeds. Conclusion. The use of these bacteria (Azospirillum with Bradyrhizobium) together contributes to increase productivity in the soybean crop.

“…The multivariate analysis techniques are important tools for this type of study and have been widely used for the genetic analysis of the relationship between traits and existing genetic material (Iqbal et al, 2008). It is also noteworthy the need for research regarding the co-inoculation practice that has been recently confirmed as agronomical efficient in Brazil but the results in the literature still vary greatly (Gitti et al, 2012;Hungria et al, 2013;Zuffo et al, 2015;Zuffo et al, 2016).…”

Co-inoculation in soybean is the mixed inoculation with bacterias of the genus Bradyrhizobium and Azospirillum brasilense. The applicability of this practice has become the subject of recent research that aims to overcome the main limitations of biological nitrogen fixation, obtained by traditional soybean inoculation with only Bradyrhizobium. This study investigated the interaction effects among cultivars, bacterium types, with and without micronutrients applied to the seeds on the initial developmental stages of soybean cultivars using multivariate analyses. The seedlings were cultivated in pots filled with soil in greenhouse conditions. The experiment was installed in the Alta Mogiana branch of the Paulista Agribusiness Technology Agency (APTA) in Colina, SP. The 32 treatments were arranged as 4 × 4 × 2 factorial with four soybean cultivars, four bacterium types, with and without micronutrients applied to the seeds. The evaluations were performed at 5, 8 and 32 days after sowing (DAS). The parameters analyzed in the pots showed that the cultivars behaved differently depending on the type of bacteria used. The co-inoculation promoted better nodulation and initial seedling growth in some cultivars. In general, cultivars without application of micronutrients were superior in terms of the parameters analyzed.
