The purpose of the study was to check the competence of the isolates in the actual soil
environment. We, therefore, indirectly approximated their symbiotic efficiency by determining …

Nitrogen fixation by leguminous trees such as sesbania (Sesbania sesban) in acid soils is
limited by aluminium (Al) toxicity and phosphorus (P) deficiency. We screened 214 East …

Relatively low soybean productivity on aluminum(Al)-rich acid soils is related to nutrient
deficiencies and ion toxicities. Nitrogen deficiency in such soils contributes to poor plant …

Forty strains of Rhizobium phaseoli, isolated from Kenyan soils, were tested for infectiveness
on common bean (Phaseolus vulgaris L.). 28 strains were infective and a cultivar× …

Density of Rhizobium population in faba bean (Vicia faba L.) fields of Wollo area (Asketema,
Gashana, Kotem, Major and Sekota) northern Ethiopia was studied. The highest population …

An experiment was conducted during January-June 2004 to evaluate acid and Al tolerance
of 88 native Bradyrhizobium strains isolated from traditional soyabean growing acidic and …

Clover rhizobia (55 strains) were screened for tolerance of acidity and Al, using the
technique of Keyser and Munns (1979). Assessment of visible turbidity after 14 days …

Bacteria were isolated from the root nodules of Vigna mungo (L.) Hepper, grown in an
arseniccontaminated field and the strain was selected by its nodulation ability as well as …

A major strategy towards addressing soil fertility depletion is the conservation and
sustainable use of rhizobia that are able to fix nitrogen in the soil in association with …

Application of Rhizobium as inoculum in acid soil requires specific characters, namely high
tolerance to pesticide residues, soil acidity, and high concentration of Aluminum. This study …
