  abstract = {{I}ntercropping of legumes and cereals appears as an alternative agricultural practice to decrease the use of chemical fertilizers while maintaining high yields. {A} better understanding of the biotic and abiotic factors determining interactions between plants in such associations is required. {O}ur study aimed to analyse the effect of earthworms on the legume-cereal interactions with a focus on the modifications induced by earthworms on the forms of soil phosphorus ({P}). {I}n a glasshouse experiment we investigated the effect of an endogeic earthworm ({A}llolobophora chlorotica) on the plant biomass and on {N} and {P} acquisition by durum wheat ({T}riticum turgidum durum {L}.) and chickpea ({C}icer arietinum {L}.) either grown alone or intercropped. {T}he modifications of the different organic and inorganic {P} forms in the bulk soil were measured. {T}here was no overyielding of the intercrop in the absence of earthworms. {E}arthworms had a strong influence on biomass and resource allocation between roots and shoots whereas no modification was observed in terms of total biomass production and {P} acquisition. {E}arthworms changed the interaction between the intercropped species mainly by reducing the competition for nutrients. {F}acilitation (positive plant-plant interactions) was only observed for the root biomass and {P} acquisition in the presence of earthworms. {E}arthworms decreased the amount of organic {P} extracted with {N}a{OH} ({P}o {N}a{OH}), while they increased the water soluble inorganic {P} ({P}i {H}2{O}) content. {I}n this experiment, earthworms could be seen as "troubleshooter" in plant-plant interaction as they reduced the competition between the intercropped species. {O}ur study brings new insights into how earthworms affect plant growth and the {P} cycle.},
