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 kg/m 2 initial to kg/m 2 . In addition, Perionyx excavatus growth and development completely was seen on the medium with 100 % cultivated ganoderma residues, reached kg/m 2 . | Journal of Science and Technology 54 (2A) (2016) 299-306 RESEARCHING GANODERMA RESIDUES APPLYING IN EARTHWORM CULTIVATION PROCESS (PERIONYX EXCAVATUS) Nguyen Thi Ngoc Nhi, Cao Van Luan, Nguyen Thi Lien Thuong* Faculty of Resources and Environment, Thu Dau Mot University, No 6 Tran Van On street, Phu Hoa ward, Thu Dau Mot city, Binh Duong province, Vietnam * Email: lienthuong@ Received: 1 April 2016; Accepted for publication: 15 June 2016 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 kg/m2 initial to kg/m2. In addition, Perionyx excavatus growth and development completely was seen on the medium with 100 % cultivated ganoderma residues, reached kg/m2. Although the growth rate of the Perionyx excavatus cultivated with Ganoderma residues was slower as compared to farming entirely by cow manure ( kg/m2), in the long run, this process will bring farmers higher profits ( VN dongs /m2 of culturing). This cultivation process might be promising to be applied in regions with mushrooms farms for economic and environmental reasons. Keywords: Ganoderma residues, Perionyx excavatus, cow dung. 1. INTRODUCTION Perionyx excavatus have high protein content, rich in essential amino acids, they are often used as food for fish [1] and chicken [2]. Therefore, in many countries such as the Philippines, Canada, Japan, China, Italy, Perionyx excavatus are cultivated in large scale to produce rich protein powder foods for animal, cattle and poultry [3]. .
