  abstract = {{T}he leaf litter of six tropical tree species ({A}cacia holosericea, {A}cacia tortilis, {A}zadirachta indica, {C}asuarina equisetifolia, {C}ordyla pinnata and {F}aidherbia albida) frequently used in agroforestry plantations in {S}ahelian and {S}oudano-{S}ahelian areas were tested for their influence on soil nitrogen content, microbial biomass and plant growth under controlled greenhouse conditions. {H}alf of the soil was planted with onion ({A}llium cepa {L}.) seedlings and the other half was not. {T}wo herbaceous species, {A}ndropogon gayanus and {E}ragrostis tremula, were also studied. {C}o-inertia analysis ({CIA}) and one-way analysis of variance ({ANOVA}) analysis showed that {C}. pinnata and {F} albida leaf powder amendment induced the highest plant growth, whereas leaf powder of {E}. tremula is associated to higher microbial biomass and {NH}4+ content. {H}igher onion seedlings growth is associated with higher concentration of nitrogen and lignin in leaf powders. {C}onversely, lower plant growth is associated to higher rates of cellulose, hemicellulose and phenols in leaves. {H}igher rates of cellulose and hemicellulose are associated with higher microbial biomass and {NH}4+, whereas phenols are associated to lower microbial biomass. {T}he results showed that amendment of {A}. holoseric a leaf powder (high concentrations of phenol) to the soil resulted in a lower microbial biomass and lower onion seedlings growth. {D}ata showed that the plant residue quality index ({PRQI}) could be a useful tool to predict the effects of litter materials on root growth in glasshouse conditions. {T}he highest values on soil and plant parameters were recorded with {C}. pinnata litter. {W}hile powdered leaf material increased the accessibility of substrates to microbes, more research with {C}. pinnata leaf litter (under a wider range of ecological conditions) is needed. {I}t could add deeper on its agronomic impact in the tropics.},
