Wastepaper as substrates for African night Crawler (Eudrilus eugeniae Kinberg)

The study assessed the different wastepaper as substrates for Eudrilus eugeniae. The study was carried out at the Center for Environmental Resources Management and Sustainable Development (CERMSD), College of Forestry, Environment and Resources Management (CFERM), Nueva Vizcaya State University (NVSU), Bayombong, Nueva Vizcaya. A Complete Randomized Design (CRD) was used with six treatments and four replications. A study used different wastepaper such as bond, notebook, carton, newsprint mixed with goat manure in 1:2 ratio. Results revealed that different wastepaper like bond paper, notebook, carton, newsprint can be successfully used as substrate for African night crawler. However, the different wastepaper had a substantial effect on the weight of vermicompost produced and the percent recovery, newsprint and goat manure in 2:1 ratio gave significantly highest weight of the vermicompost produced and highest percent recovery. Hence, this substrate is recommended for vermicomposting using goat manure. Laboratory analysis of vermicompost as to its NPK content, nitrogen gave 0. 87% to 1.05%, for phosphorus amounted to 0.57135% to 1.06027%, and potassium measured 0.001471% to 0.001639%. From the result the NPK content of the different treatments is low. Regardless of the amount of nutrients contained in these substrates, these can help in enhancing soil fertility and is vital for plant growth and development. At the same time, through this process, the paper waste problem can be addressed while producing vermicompost that can be used as an organic fertilizer.
