Abstract


The research of applying Ganoderma residue in earthworm Perionyx excavatus cultivation have promised in reducing environmental pollutions from mushroom farm and brought high economic efficiency. A 9 m square with 9 experimental formulas were applied to investigate the effect of Ganoderma residue to earthworm growth. The results showed that Perionyx excavatus increased mass in all formulas added cultivated Ganoderma residues, in which the largest increased in formula of 75 % cultivated Ganoderma residues treated with Trichoderma, from 0.59 kg/m2 initial to 2.62 kg/m2. In addition, Perionyx excavatus growth and development completely was seen on the medium with 100 % cultivated ganoderma residues, reached 1.89 kg/m2. Although the growth rate of the Perionyx excavatus cultivated with Ganoderma residues was slower as compared to farming entirely by cow manure (2.94 kg/m2), in the long run, this process will bring farmers higher profits (56.500 VN dongs /m2 of culturing). This cultivation process might be promising to be applied in regions with mushrooms farms for economic and environmental reasons.
