Abstract: MAGSINO, JULIEN ARVIN D. and DHANNA REGINA QUIZON. “Organic Substrates for Vermicomposting”. Research Study (General Science Curriculum). Cavite State University, Science High School, Indang, Cavite. April 2008. Adviser: Dr. Analita dM. Magsino The suitability of different combinations of organic materials as substrates for vermicomposting was investigated in an experiment following a Completely Randomized Design with three replications of four treatments, namely: T,- Wild sunflower leaves, madre de cacao and cow manure, T>- Cut grasses, madre de cacao and cow manure, T3- Pineapple leaves, madre de cacao and cow manure, and T,- Rice straw, madre de cacao and cow manure. The organic materials were mixed at a ratio of 2:1:1 and allowed to decompose using African nightcrawlers (Eudrilus euginae). Vermicompost yield, vermicompost quality and worm biomass were monitored. The different organic mixes significantly affected the amount of substrates recovered after 25 days of anaerobic decomposition. Percentage recovery was highest in T4 (83.33%) followed by T; and T (66.67%) and lastly, T3 (54.66%).The type of organic substrates also significantly affected vermicompost yield and recovery after 35 days of worm feeding. Highest percentage recovery was computed in T, (62.75%) although not significantly different from Tz (41%). The substrates containing rice straw and cut grasses as primary components gave the highest vermicompost production. Unreplicated laboratory analysis of vermicomposts resulted in pH values of 6.8 - 7.6, total N of 1.20 - 2.26%, total P2Os of 0.29 - 0.55 % and total K2O of 0.58 to 2.30%. The different types of organic substrates did not significantly affect worm proliferation rate in terms of worm biomass

The suitability of different combinations of organic materials as substrates for vermicomposting was investigated in an experiment following a Completely Randomized Design with three replications of four treatments, namely: T,- Wild sunflower leaves, madre de cacao and cow manure, T>- Cut grasses, madre de cacao and cow manure, T3- Pineapple leaves, madre de cacao and cow manure, and T,- Rice straw, madre de cacao and cow manure.

Vermicompost yield, vermicompost quality and worm biomass were monitored.

The different organic mixes significantly affected the amount of substrates recovered after 25 days of anaerobic decomposition. Percentage recovery was highest in T4 (83.33%) followed by T; and T (66.67%) and lastly, T3 (54.66%).The type of organic substrates also significantly affected vermicompost yield and recovery after 35 days of worm feeding.
