  abstract = {{T}he aim of this study was to compare the rhizobial symbiosis and carbon ({C}) and nitrogen ({N}) accumulations in soil and plants in intercropping versus sole cropping in biennial rotation of a cereal-durum wheat ({T}riticum durum {D}esf.), and a {N}-2-fixing legume-faba bean ({V}icia faba {L}.) over a three-year period at the {INRA} ({N}ational {I}nstitue of {A}gronomic {R}esearch) experimental station in the {M}auguio district, south-east of {M}ontpellier, {F}rance. {P}lant growth, nodulation and efficiency in the use of rhizobial symbiosis ({EURS}) for the legume, nitrogen nutrition index ({NNI}) for the cereal, and {N} and {C} accumulation in the soil were evaluated. {S}hoot dry weight ({SDW}) and {NNI} were significantly higher for intercropped than for the sole cropped wheat whereas there was no significant difference on {SDW} between the intercropped and sole cropped faba beans. {EURS} was higher in intercropped than in sole cropped faba bean. {F}urthermore, by comparison with a weeded fallow, there was a significant increase in soil {C} and {N} content over the three-year period of intercropping and sole cropping within the biennial rotation. {I}t is concluded that intercropping increases the {N} nutrition of wheat by increasing the availability of soil-{N} for wheat. {T}his increase may be due to a lower interspecific competition between legume and wheat than intra-specific competition between wheat plants, thanks to the compensation that the legume can achieve by fixing the atmospheric nitrogen.},
