  abstract = {{M}aize was grown under field conditions in the presence and absence of the tropical endogenic earthworm #{M}illsonia anomala$ ({O}modeo and {V}aillaud, 1967) in soil of a secondary forest of central {I}vory {C}oast. {E}xperimental units were isolated by {PVC} sheets to limit earthworm movements. {D}ecomposition and redistribution of nitrogen from maize crop residues incorporated in the soil were monitored using 15{N}-labelled residues. {T}he density of #{M}. anomala$ decreased from 50 to 15.9/m2 during the cultivation period (90 days). {A}ctivity of #{M}. anomala$ significantly modified the structure of the soil by increasing the proportion of large aggregates (over 2 mm in diameter). {M}aize production was increased by 12% for stalks and 18% for grains in the presence of earthworms. {N}itrogen contained in the maize residue was more efficiently used by plants grown in the presence of earthworms ; the real coefficient of utilisation of the organic residue increased from 9 to 11% in the presence of #{M}. anomala$. {N}onetheless, total nitrogen exportation was not significantly different between the two treatments. {F}urthermore, {N} from the organic residues left after the cultivation period was less easily assimilated by plants in treatments with earthworms.
