“…Notwithstanding the difference in MPN estimates of indigenous rhizobia capable of nodulating S. senegal in Dahra and Goudiry soils, inoculation in most cases improved nodulation. In addition, indigenous rhizobial strains originally isolated from Goudiry generally performed better than exogenous strains in Goudiry soil despite high indigenous populations, indicating the importance of selection and re-inoculation with an effective indigenous strain as previously demonstrated in Sesbania sesban by Makatiani and Odee (2007). Besides natural adaptation, the reinoculated strain is also expected to reduce competion for nodulation from other compatible indigenous soils.…”

Acacia senegal, gum arabic tree) provenances, namely Dahra (Senegal), Tera (Niger) and Makueni 28(Kenya) to inoculation with selected S. senegal-nodulating rhizobia in soils from Dahra and Goudiry regions of 29Senegal, representing typical soil and enviromental conditions for establishing gum arabic production 30 plantations. 31Methods A greenhouse experiment was performed to evaluate the effect of 11 rhizobial strains on nodulation and 32 growth of three S. senegal provenances in two field soils, differing in nutrient status and indigenous rhizobia. 33After 4 months, plants were harvested for determination of nodulation, shoot and root dryweight. 34Results Nodulation and growth of S. senegal varied in relation to rhizobial strain, provenance, soil type, and their 35interactions. Generally, nodulation was higher in Dahra than Goudiry soils, while Makueni provenance was the 36 most compatible host. Inoculation had a significant effect on all parameters measured in Dahra field soil. By 37 contrast, inoculation had a significant effect on height (shoot length), and shoot, root and total dry matter but not 38 on nodulation. In the two field soils, seed provenance effect was significant for all parameters measured. The 39interaction between inoculation and provenance showed a significant effect on all parameters measured except 40 nodule number in Dahra field soil while in Goudiry, the interaction had a significant effect on seedling height 41 and shoot, root, and total dry matter but this effect was not significant with nodulation parameters. 42Conclusions S. senegal is variable in its response to inoculation, it is therefore advantageous to select and match 43effective rhizobia-provenance symbionts for each site. 47In the arid and semi-arid lands of Africa, low and erratic rainfall, high temperatures and poor soil water and 48 nutrient availability limit agricultural productivity (Mertz et al. 2012 69and to cater for gum production, which is an important source of cash (Fagg and Allison 2004). The N2-fixing 70 capacity of a legume tree is often used to explain its ability to grow better on and restore the fertility of N- 71depleted soil (Dommergues 1995). 72S. senegal is a promiscuous species that could be nodulated with various rhizobial taxa and strains (Bakhoum et al. 2014; d...

Centrolobium tomentosum is a tropical legume tree indicated for functional and structural restoration of riparian areas. This study was conducted to characterize the rhizobia isolated from nodules of C. tomentosum in situ and to determine their capacity of renodulation, in an experimental area of land rehabilitation in the Rio Doce valley. Nodulation potential to inoculation with 2 selected fast-growing Rhizobium strains separately and a mixed inoculum of arbuscular mycorrhizal fungi was evaluated by the use of antibiotics resistance. Flood disturbance were observed not to affect renodulation by fast-growing strains. DNA fingerprinting RAPD (random amplified polymorphic DNA) and lipopolysaccharides (LPS) profiles were used to examine molecular relationships among field isolates, inoculants and reference strains. Maximal renodulation was exhibited by strain BHCBAb1 after 24 months after transplantation. Centrolobium tomentosum forms symbiosis with fast-and slow-growing Rhizobium strains, and it is suggested that their nursery culture could be improved by inoculation of selected strain under low nitrogen-input conditions.

“…Hence, the hypothesis of this work was stated that inoculation of rhizobia isolated from native soil improves the nodulation and yield of peanut even though the soil native rhizobia population has been > 10 2 g −1 soil. Our approach has been to utilize indigenous rather than exotic rhizobia, since the former, already adapted to the existing ecological conditions, can provide very satisfactory results (Douka and Xenoulis 1987;Hungria et al 1996;Makatiani and Odee 2007). Therefore, the objective this work was to evaluate the symbiotic effectiveness of selected indigenous Bradyrhizobium sp.…”

Background: Bacterial bioinoculate is one of environmentally friendly input for crop production. Several works revealed that effectiveness of Rhizobium bioinoculant have been affected by the native rhizobia population. Hence, this study was initiated to evaluate the effect of selected Bradyrhizobium in nodulating peanut in the major growing areas of Ethiopia. Methods:The effect of eight effective Bradyrhziobium vis-a-vis 20 kg N ha −1 and the control check on the nodulation and yield of two peanut cultivars (Sedi and Werer 942) at Babile and Fedis, eastern Ethiopia, during 2013 cropping season was evaluated. Results:The results showed that the inoculation, location and cultivar and their two and three ways interaction had a significant influence on the nodulation and grain yield. Inoculation of Bradyrhizobium increased the nodule number, nodule dry weight, number of seeds per plants, total pods weight, hundred seeds weight, total biomass yield, grain yield and shelling % up to 37, 24.9, 22.4, 22.5, 5.5, 26.2, 35.8 and 24.1%, respectively. Isolate HUGNR-29 was found to be more effective as it scored the highest nodule dry weight and grain yield. Application of inorganic N increased the yield and yield components of peanut in either of locations. Though the statistically better effective nodule % was recorded at Babile, significantly higher nodule number, nodule dry weight, and total N accumulation were obtained from Fedis than Babile site. Significantly higher total pods weight, hundred seeds weight, total biomass weight, grain yield and total plant N accumulation was recorded with the cultivar werer-962 than those produced with Bati-Sedi. Conclusions:The result showed that Bradyrhizobium inoculation is essential to improve the peanut production through environmentally and economically sustainable ways though the soil native rhizobia nodulating peanut was high. Peanut cultivar and study site based rhizobia inoculant development is also important.
