“…These results differ from those reported by Santos et al (2017), who did not find significant difference between the control treatment and single or combined inoculation with B. japonicum and A. brasilense for the number of branches per plant in the peanut cultivar IAC Tatu ST.…”

“…Similar results were obtained by Santos et al (2017), who found that single and combined inoculation with B. japonicum and A. brasilense influenced the number of leaves of peanut plants. This is because nitrogen is closely linked to the photosynthetic process, as it is a component of the chlorophyll molecule (LIN et al, 2009).…”

“…These results further confirm the relevance of BNF for legume plants to grow and develop CAMPO;MENDES, 2007;GUIMARÃES et al, 2016). Santos et al (2017) observed that the single inoculation of Bradyrhizobium japonicum and A. brasilense and the co-inoculation with both significantly influenced the height of peanut plants, with the highest value obtained in the co-inoculated treatment. Silva et al (2017) obtained higher height of peanut plants, compared to the control treatment (without inoculation), in the co-inoculated treatment (B. japonicum + A. brasilense).…”

The aim of this study was to evaluate the effect of inoculation with rhizobium and co -inoculation with Azospirillum brasilense on phytometric characteristics of peanut plants grown in Latossolo Vermelho (Oxisol) with and without compaction. The experiment was conducted in a greenhouse, with a randomized block design in a 5x2 factorial scheme and 4 replicates, totaling 40 experimental units. Treatments were composed by commercial inoculant for peanuts (SEMIA 6144 strain); MT 15 strain; combination of MT 15 + A. brasilense; nitrogen control and absolute control. Plant height, number of leaves, number of branches per plant, stem diameter and Falker chlorophyll index were evaluated. The data were subjected to analysis of variance and, when significant, to Tukey test at 1% probability level. For the variables plant height, number of leaves, number of branches and stem diameter, the results were similar for all treatments, except for the absolute control and number of branches at 90 days after emergence (DAE) and stem diameter at 30 and 90 DAE. For stem diameter at 30 DAE, the results were similar to those found in the treatments with co -inoculation, commercial inoculant and nitrogen fertilization. There was interaction for Falker chlorophyll index at 60 DAE, with the best result found in the MT 15 strain. Inoculation with MT15 and co-inoculation with A. brasilense promoted good performance in peanut crop in terms of phytometric characteristics in soil with and without compaction.

O tamanho da semente é um importante indicador físico da qualidade fisiológica das sementes, pois pode afetar a taxa de germinação e o crescimento inicial das plântulas. Neste contexto, o presente estudo teve como objetivo avaliar os efeitos do tamanho das sementes e da inoculação de Bradyrhizobium japonicum e Azospirillum brasilense de forma isolada ou combinada na emergência das plântulas, nodulação das raízes e no crescimento inicial das plantas de amendoim (Arachis hypogaea L., cv. IAC Tatu ST). As plantas foram cultivadas em vasos plásticos de 8,0 L preenchidos com um solo arenoso do Cerrado e mantidas sob condições de casa-de-vegetação. O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial 3 × 4 com quatro repetições. Os tratamentos foram constituídos por três tamanho de sementes (pequena, média e grande) e por quatro tratamentos de inoculação: i) controle (sem inoculação); ii) inoculação das sementes com Bradyrhizobium japonicum; iii) inoculação das sementes com Azospirillum brasilense; e, iv) coinoculação das sementes com B. japonicum e A. brasilense. Os resultados reportaram que a utilização de sementes grandes melhorou a nodulação das raízes, o crescimento das plantas, o acúmulo e a partição de matéria seca das plantas. Portanto, a implantação da cultura do amendoim deve ser realizada com a utilização de sementes de maior tamanho (grandes), por proporcionar sustentabilidade para o sistema de produção de amendoim, melhorando a fixação biológica de nitrogênio e o crescimento das plantas cultivadas em solos arenosos do Cerrado Sul-mato-grossense. A coinoculação das sementes com B. japonicum e A. brasilense melhorou a nodulação das raízes e a altura das plantas, no entanto, não teve efeito no crescimento, na partição de matéria seca e nos índices morfofisiológicos das plantas de amendoim, quando cultivadas em solos arenosos do Cerrado sob condições controladas.

“…Bacteria of the genus Azospirillum are the most frequently used PGPR in Brazil and worldwide (Bulegon et al., 2017; Hungria, Nogueira, & Araujo, 2015; Marks, Megías, Nogueira, & Hungria, 2013), but little is known about their interaction with rhizobia when both are applied on peanut seeds (Santos, Bush, Silva, Zuffo, & Steiner, 2017). Recent research results have proven the beneficial effects of co‐inoculation of rhizobia and Azospirillum brasilense on nodulation, N acquisition, and growth of leguminous plants, especially on soybeans and common beans (Bulegon et al., 2017; Chibeba et al., 2015, Hungria et al., 2015; Steiner, Ferreira, & Zuffo, 2019).…”

The use of plant growth–promoting rhizobacteria (PGPR) associated with rhizobia may improve biological N fixation, nutrient acquisition, and grain yield of the peanut (Arachis hypogaea L.). However, few studies have reported the effect of inoculation of rhizobia and PGPR in association with Mo in tropical soil conditions. This study examined the effectiveness of (co)inoculation with Bradyrhizobium spp. and/or Azospirillum brasilense and Mo application in improving the yield response of creeping peanut crop (‘RUNNER IAC 886’). The effects of rhizobacteria and Mo on nodulation, crop growth, chlorophyll content, and yield of peanut were investigated in a moderately acidic sandy soil (pH 5.0) from the Brazilian Cerrado during the 2016–2017 and 2017–2018 growing seasons. Four seed inoculation treatments (control [uninoculated seeds], inoculation with Bradyrhizobium spp. strains SEMIA 5079 and SEMIA 5080, inoculation with Azospirillum brasilense strains Ab‐V5 and Ab‐V6, and co‐inoculation of Bradyrhizobium spp. and Azospirillum brasilense) and two Mo levels (0 and 200 mg Mo kg−1 of seed) were studied. Results showed that the effects of the interaction between rhizobacteria and Mo application were not significant (p > .05) for all crop traits. Root nodulation, dry matter accumulation, and chlorophyll content were significantly greater in Mo‐treated peanut plants than control plants in both seasons. However, the response of crop grain yield was significantly greater (17.7%) in Mo‐treated plants only in the 2017–2018 season. Therefore, the improved root nodulation, crop growth, and chlorophyll content resulting from Mo application can lead to increased pod and grain yield in peanut. Inoculation with Bradyrhizobium spp. alone or combined with A. brasilense enhanced root nodulation, chlorophyll content, and peanut grain yield. Over two harvests, average peanut grain yield increased by 25.3 and 24.0% with inoculation of Bradyrhizobium spp. alone and combined with A. brasilense, respectively, compared with noninoculated plants. Due to lower cost and higher profitability, inoculation of Bradyrhizobium spp. alone is the most efficient practice for peanut cropping in sandy soils of the Brazilian Cerrado. Together with Mo application, these agricultural practices can be recommended for Brazilian peanut farmers.
