The earthworms are organisms of the edaphic fauna with great capacity of transformation of
organic residues with stabled composting. The potential of these organisms have the advantage
in the earthworm-breeding, seeking the humus production as organic fertilizer, and earthworm´s
biomass, as food for several animals. However, many organic residues are not often used,
staying in conditions that cause damages to the atmosphere. This work has the objective to
evaluate the utilization of natural rice husk, charred rice husk and cattle manure in the Eisenia
andrei Bouché (1972) reproduction. The treatments evaluated were: 1) charred rice husk 50%
and cattle manure 50%; 2) charred rice husk 25% and cattle manure 75%; 3) natural rice husk
50% and cattle manure 50%; 4) natural rice husk 25% and cattle manure 75% and 5) cattle
manure 100%. The individual experimental units was the black plastic bags where was
adicionated four liters of substrate relating the each treatment and six adult earthworm of the
specie E. andrei. The study was conducted in greenhouse and were evaluated the number of
young and adult earthworms, the number of cocoons, the biomass and multiplication index 60
days after the earthworm?s inoculation. The experimental design adotaded was the completely
randomizy with five treatments and five repetitions. It was observe the larger number of young
earthworms in the treatments constituted by natural rice husk 50% and cattle manure 50%,
natural rice husk 25% and cattle manure 75% and cattle manure 100%, the largest value
observed, 269 earthworms, when was used equals proportions of cattle manure and natural
rice husk. The larger numbers of earthworm?s biomass was obtained in the treatments that had
addition of natural rice husk to the cattle manure and in the treatment cattle manure 100% that
not show statistical difference between the tratments. The addition of charred rice husk was
less efficient that the addition of natural rice husk in all parameters evaluated in this study. In this
case, preferential utilization of natural rice husk in the two proportions evaluated with cattle manure
in comparation to the charred rice husk. It was concluded that the substrates constituted by
natural rice husk 25% and cattle manure 75% and natural rice husk 50% and cattle manure 50%
were more adequate to the multiplication of E. andrei. The development of E. andrei, evaluated
by the earthworm?s biomass was superior in the substrates constituted by natural rice husk
25% and cattle manure 75%, natural rice husk 50% and cattle manure 50% and cattle manure
100%. MenosThe earthworms are organisms of the edaphic fauna with great capacity of transformation of
