Abstract

The aims of this study were to know the preference and the rate of population growth of local worm (Pontoscolex corethrurus Fr. Mull) at several rearing medium.

Each treatment consists of 5 replications. The result of research showed that the difference of various rearing medium gave the different influence toward the preference and the rate of growth of local worm (Pontoscolex corethrurus Fr. Mull). The result showed that preference of local earth worm of several rearing media from highest to lowest value were garden soil media 38.2 individuals/24 hours, compost of dried rice stalks media 7 individuals/24 hours, compost of sawdust media 3 individuals/24 hours, and grass compost media 1.8 individuals/24 hours.
