CRIANZA DE Eisenia foetida (LOMBRIZ ROJA) EN DIFERENTES SUSTRATOS DE DESARROLLO BIOLÓGICO

Abstract

The use of organic waste is a viable environmental alternative, the sources being an organism that allows a rapid decomposition process. The research of rearing red worms in different substrates of biological development, was carried out during June and July 2019. The objectives were: a) To determine the influence of the type of substrate (type of treatment) on the increase of stumps and biomass of the red worm, b) Estimate the degree of association between number of worms, number of stumps, length and biomass in different substrate treatments. The methodology consists of implementing three types of substrate and one of control, analyzing animal faeces and fruit remains. Assessment of temperature, humidity and pH was performed every two days, and the number of earthworms, cocoons, length and biomass every 12 days. Results were as follows: the number of red earthworm cocoon increased to six cocoons or eggs in 36 days (average 4.33 cocoons/earthworm), with the treatment with animal manure and fruit peels, as the one with higher number of cocoons, in relation to the other treatments. The highest degree of association was recorded between length (mm) and the biomass (g) of earthworms, with a value of r = 0.82.
