The worms (Eisenia fetida) doubled their weight by day 68 in KPW and CMY vermicomposts and day 90
KPW vermicompost produced the greatest weight of worms. The direct seed germination method (seeding
into soil or vermicompost–soil mixtures) indicated that KPW and KYW feedstocks decreased germination
compared to the control, even in mature vermicompost. Seed germination was greater in the
water extract method; however, most of the vermicompost extracts suppressed germination of the three
seed species compared to the water controls. Vermicomposts from all three feedstocks increased leaf area
and biomass compared to the control, especially in the 10% vermicompost:soil mix. Thus, seed germination
and leaf area or plant biomass for these three species are contrasting vermicompost quality
indicators.
