  abstract = {{C}ommon bean ({P}haseolus vulgaris {L}.) has the capacity to fix atmospheric {N}-2 into the biosphere through its aptitude to establish a symbiosis with soil rhizobia. {I}n order to search for environmental constraints that might limit this symbiosis a nodular diagnosis was performed in eighteen field sites chosen with farmers of the {S}etif agro-ecosystem. {C}ommon bean was used as a model grain-legume with six recombinant inbred lines ({RIL}s) and one local genotype {D}jadida. {A}t flowering stage, the biomass of plants and nodules was determined by excavating 20 cm in depth and around the root-system of ten plants per genotype and per site. {T}he results indicate a large spatial variation in nodulation and growth between genotypes, and the distribution of soils in four soil clusters, based on physico-chemical properties. {T}he inhibition of nodulation of all genotypes in soil of clusters {A} and {B} was associated with high residual soil mineral nitrogen (2.23 +/- 0.49 g kg(-1) soil). {T}he low nodulation of all genotypes in the phosphorus ({P}) deficient soil of cluster {C} (6.73 +/- 3.63 mg kg(-1) soil) was partly compensated by increasing their efficiency in use of the rhizobial symbiosis (13%), estimated by the slope of the regression model of shoot biomass as a function of nodule biomass. {I}nterestingly, significant correlations were found between nodulation of all genotypes and {O}lsen-{P} content in soils of clusters {C} ({R}-2 = 0.97, {P} < 0.001) and {D} ({R}-2 = 0.94, {P} < 0.05). {I}t is concluded that the {RIL}s selected for their efficient use of {P} for symbiotic nitrogen fixation show the highest nodulation and growth and that the nodular diagnosis can be used to assess the growth response of {N}-2-dependent grain-legume to soils with low availabilities of {N} and {P}.},
