  abstract = {{I}n the {H}ighlands of {M}adagascar, providing organic amendments ({OA}s) is the main farmer fertilization practice in upland rainfed agrosystems dominated by nutrient-depleted {F}erralsols. {T}herefore, enhancing the performance of {OA}s on plant functions is particularly important for improving both plant productivity and agrosystem sustainability. {E}arthworms are well-known ecosystem engineers involved in the decomposition of organic matter and play a critical role in nutrient turnover. {I}noculating earthworms could be a promising approach to improve the fertilizer performance of {OA}s. {H}owever, there is limited knowledge regarding the interaction between earthworms and {OA}s of varying biochemical qualities on plant growth and nutrition. {I}n this microcosm experiment, we assessed the effect of different types of {OA}s (i.e., unamended control, conventional farmyard manure, kraal manure, improved farmyard manure, compost, vermicompost, urban waste, taroka, poultry droppings, pig manure) and earthworm inoculation (with and without earthworms) on the growth and nutrition of rice. {T}he endogeic species {P}ontoscolex corethrurus ({R}hinodrilidae) was used in the experiment. {A}fter eight weeks of growth, the poultry droppings had the best fertilizer performance, followed by improved farmyard manure and pig manure in treatments without earthworms. {T}he main driver of fertilizer performance appeared to be the quality of {OA}s. {H}owever, other mechanisms, such as an increase in soil p{H}, may also play a significant role. {T}he inoculation of earthworms significantly enhanced the fertilizer performance of {OA}s but the magnitude of this enhancement depends on the {OA}s. {O}verall, {OA}s with low fertilizer performance showed a more pronounced response to earthworms. {A}dditionally, earthworms improved the performance of high-quality {OA}s likely by enhancing the availability of {P} and {M}g. {O}ur findings emphasize the synergistic effects of earthworms and {OA}s of various qualities on plant growth and nutrition, offering valuable insights for improving fertilization practices in nutrient-poor {F}erralsols of {M}adagascar.},
