  abstract = {{N}itrogen nutrition of legume relies on both soil mineral {N} absorption and symbiotic nitrogen fixation by rhizobia and the symbiotic interaction depends on each of the partners. {T}his study evaluates the variability of symbiotic efficiency on the growth of two cultivars of pea and lentil inoculated with 16 different rhizobial genotypes originating from sub-humid and semi-arid regions of eastern {A}lgeria. {T}he genotypes were defined by the combination of haplotypes characterized by r{RNA} intergenic spacer ({IGS}) and a nodulation gene marker (nod{D} region). {A}nalysis of shoots, roots and nodules is an effective method to examine plants growth. {T}he results revealed that efficiency is linked to the rhizobial genotype, effect of the strains, and host plant species. {A} statistically significant interaction between cultivar and rhizobial genotype was only found for nodule number, size and biomass in forage pea. {W}ith respect tothe development of tested plants, strains having genotypes originating from sub-humid zones are more effective than those originating from semi-arid zones. {T}his functional variability is strongly linked to the genetic variability of the chromosomal ribosomal {IGS}. {S}trains isolated from lentil are more effective for lentil growth than those isolated from pea. {T}he nitrogen content correlated with the plant growth. {I}n conclusion, the inoculation of plants cultivated in a semi-arid soils with effective strains from a sub-humid origin is likely to be more beneficial for plants under conditions of environmental stress.},
