“…e results obtained with BR 3267 relative to pod production in groundnut in this work are in agreement with the findings of Howarth et al [26], who reported a positive response of pod number and pod dry weight of groundnut following inoculation and attributed this to the presence of effective strains of rhizobia inoculated. e higher number of pod obtained by the application of 40 kg•N/ha compared with 20 kg•N/ha in cowpea agrees with the studies carried out by [27], who reported significant increases in pod number by increasing the amount of nitrogen applied.…”

Inoculating groundnut and cowpea with highly effective and competitive rhizobial strain improves nodulation. A field experiment was carried out at the experimental field of the Faculty of Agriculture, University for Development Studies, Nyankpala, to evaluate the growth and yield responses of cowpea and groundnut to five rhizobial inoculant strains in the Guinea Savanna zone. The experiment was laid out in a randomized complete block design (RCBD) with eight (8) treatments replicated four (4) times. The treatments included five rhizobial inoculant strains (NC 92, KNUST 1002, KNUST 1003, KNUST 1006, and BR 3267), two N fertilizer levels (20 kg·N/ha and 40 kg·N/ha), and a control. The results showed that rhizobial inoculation and N fertilizer application increased nodulation, biomass yield, pod number, pod weight, hundred seed weight, nodule dry weight, and pod yield of groundnut compared with the control. Rhizobial inoculation averagely increased the nodulation and yield by 63 and 67%, respectively, compared with the control. Mineral N fertilizer (20 kg N/ha) on average increased the nodulation and yield by 24 and 25%, respectively, compared with the control plots. It can be recommended from this study that, in the absence of highly competitive rhizobial strains such as KNUST 1006 and NC 92 as biofertilizers for increasing the nodulation and yield of cowpea and groundnut, 20 kg·N/ha can be used for the purpose. Further research is recommended using these rhizobial strains in combination with lower rates of N fertilizers (<20 kg·ha−1).

“…Bradyrhizobium strains are the favorite micro-symbionts of peanut and large amounts of nitrogen can be fixed in trials under field conditions (Thies et al 1991;Valetti et al 2016). Within the Bradyrhizobium group, peanuts can nodulate with bacteria belonging to the B. elkanii clade, such as the commercial strain SEMIA 6144 or the clade B. japonicum, as several isolated strains from the semi-arid region of Brazil (Santos et al 2017a).…”

“…Peanut is able to associate efficiently with different rhizobial strains (Melo et al 2016), presenting higher efficiency the Bradyrhizobium genus (Valetti et al 2016;Santos et al 2017a). During the last years, some studies have been carried out in Brazil aiming to evaluate the biodiversity (Lyra et al 2013;Torres-Júnior et al 2014;Santos et al 2017a), the symbiotic efficiency (Torres-Júnior et al 2014;Santos et al 2017a, b), and the agronomic efficiency of new rhizobium strains (Sizenando et al 2016).…”

Drought is one of the environmental factors that most affects peanut cultivation in semi-arid regions, resulting in economic losses to growers. However, growth promoting bacteria are able to reduce water deficit damage in some plant species. In this context, this study aimed to evaluate the interaction of Bradyrhizobium strains reducing water stress effects on peanut genotypes by antioxidant enzymes activities, leaf gas exchanges and vegetative growth, as well as to determine the taxonomic positioning of strain ESA 123. The 16S rRNA gene of ESA 123 was amplified by PCR and sequenced by dideoxy Sanger sequencing method. An experiment was performed in greenhouse with three peanut genotypes (BRS Havana, CNPA 76 AM and 2012-4), two Bradyrhizobium strains (SEMIA 6144 and ESA 123), a mineral source of N and an absolute control (without N) under two water regimes (with and without irrigation). Seeds of peanut were sown and the plants were grown until 30 days after emergence. On the 20th day, the water deficit plants group had their irrigation suspended for 10 days. At in silico analyzes, ESA 123 presented 98.97% similarity with the type strain of B. kavangense. Leaf gas exchange was affected by water deficit; as well as alteration of antioxidant activities and reduction of vegetative growth variables. However, some plants inoculated with SEMIA 6144 and ESA 123 strains presented lower reductions and increment of some evaluated variables, mainly the ones inoculated with the ESA 123 strain, Bradyrhizobium sp. from the semi-arid region of Northeast Brazil. This data suggests beneficial effects of the peanut-Bradyrhizobium interaction in a water stress condition, specially with the ESA 123 strain.

“…The plants inoculated with the test isolate (23M) did not differ statistically neither, from the treatment that received inoculation with the strain SEMIA 6144, nor from noninoculated plants. According to Souza et al (2008), the biomass accumulation is a strong indicator of the nutritional status of the plants and has been one of the variables used in studies for selecting rhizobia isolates with potential for BNF (Marcondes et al, 2010;Torres Júnior et al, 2014;Valetti et al, 2016).…”

Peanut (Arachis hypogaea L.) is capable of establishing an efficient symbiosis with a wide range of rhizobia, nevertheless, the inoculation of this legume is under used due to lack of information on the bacteria naturally established in soils and the agronomic and economic viabil ity of the practice. The aim of this study was to evaluate the diversity and the symbiotic efficiency of peanut rhizobia from a Planosol under different vegetation covers (native vegetation, sugarcane cultivation and fallow after sugarcane cultivation), located in Zona da Mata, Northeast of Brazil. A total of 177 isolates were obtained from peanut nodules, most of them having the characteristic of rapid growth and acidification of the Yeast Mannitol Agar (YMA) medium. The isolates obtained from soil sample s with native vegetation cover showed higher relative abundance, higher species richness and greater uniformity of morphological groups of rhizobia. Eighteen isolates were evaluated for their ability to nodulate peanuts, of which 13 have been authenticated and submitted to evaluation of symbiotic efficiency in pots with soil. The isolate 23M showed the best symbiotic performance in pots with soil. In the field, plants inoculated with the isolate 23M showed better performance than non-inoculated plants, in addition to a grain yield (kg ha -1 ) similar to that of plants inoculated with recommended bacteria or receiving 200 kg ha -1 N.
