  abstract = {{A}ims: {I}n {M}adagascar, agroecological practices to increase and sustain upland rice productivity are based on an intensification of soil ecological processes. {S}tudy {D}esign: {T}he effects of earthworm presence and identity ({P}ontoscolex corethrurus, {D}ichogaster saliens, or no earthworms), residue presence and identity [{C}rotalaria grahamiana ({F}abaceae), {D}esmodium uncinatum ({F}abaceae), {S}tylosanthes guianensis ({F}abaceae), {E}leusine coracana ({P}oaceae), {Z}ea mays ({P}oaceae) or no residues] and residue location (mulched or buried) on nutrient availability and rice growth and yield were investigated in outdoor mesocosms. {T}hirty three treatments were managed in a completely random design. {P}lace and {D}uration of {S}tudy: {T}he experiment was conducted at {A}ndranomanelatra near {A}ntsirabe, {V}akinankaratra region, in the highlands of {M}adagascar in 2016. {R}esults: {E}arthworms had no effect on soil nutrient availability and positive effects on plant biomass. {N}evertheless, the presence of earthworms increased the shoot:root ratio. {T}he main significant effects on soil properties and crop yields were due to the presence, identity and location of the residues. {T}he addition of {D}esmodium residues enhanced the total plant biomass, rice grain yields, soil nitrate content and total {P} uptake by rice. {N}o significant interactive effect was found between earthworms and residues on plant and soil properties. {C}onclusion: {T}he most striking finding of the present study was that the identity and location of the residues were the most important factors influencing soil nutrient content, plant growth and crop production, irrespective of earthworm presence},
