Comparative analysis of vermicomposts with different substrates of non-ruminants animals with African earthworms

The earthworm began to expand around the world in the 70s, and became the target of studies by the scientific community. The aim of this work is to evaluate the reproduction and development of giant African earthworms on different substrates with non-ruminant animal manure, Bushveld signal grass and Orelha-de-Onça. To evaluate the productive and reproductive development of African giant earthworms on different substrates of non-ruminant animals. The work was carried out at the Federal Rural University of Pernambuco (UFRPE) – Serra Talhada academic unit (UAST) - PE, being divided in two stages, in the first one the substrates were produced and in the second one the vermicompost was produced. After the end of 35 days the worms were counted, washed and weighed where they had the in-natura weight of each repetition of the treatments, after they were added in identified bags and these were taken to the definitive drying oven, at the end the bag was removed and weighed again obtaining the dry weight. Analysis of variance was performed for the following variables: N, Ca, Mg, P, K, Zn, Cu, B, Fe, Mn, CEC, pH and weight of adult worms. The vermicompost with the highest levels of macro and micronutrients is the substrate with rabbit manure.
