Avaliação do desempenho de minhocas da espécie Eisenia andrei (Bouchê 1972) criadas em diferentes resíduos orgânicos.

Abstract

Population growth brings as consequences the increase in production and disposal of organic waste, which are mostly discarded in places inappropriate without prior treatment. Vermicomposting is a low-cost and of easy handling that contributes to the recycling of these residues, resulting in a good quality vermicompost (humus) that meets the needs of the plants. The objective of this work was to observe the reproductive capacity and adaptability of earthworms of the species Eisenia andrei (California Red) in different substrates. The research was carried out at the Federal University of Campina Large campus Cuite/PB. Earthworms were exposed to the following substrates: T1- organic compost (witness); T2- organic compost + pineapple peel + Bell pepper; T3- organic compost + tomato + watermelon rind; T4- compound organic + potato skins + carrots. During the experiment period it was The dismantling of the vessels was carried out twice in order to account for the rate of reproduction and remanence of earthworms in their respective substrates. You treatments have shown that earthworms are able to adapt and reproduce on different substrates, but treatment 2 was the one that achieved the best performance for reproduction and adaptation of earthworms, surpassing the other treatments. At physicochemical compositions of the vermicompost are in accordance with the legislation of the Normative Instruction No. 25/2009 for organic compounds in relation to pH and humidity.
