Abstract:

Vermicompost prepared from teak leaf litter (TLL), paper mill sludge (PMS) and pressmud (PM) in combination with cowdung (1:1) using the epigeic earthworm, Perionyx ceylanensis for 60 days was stored in ambient conditions, then studied for selective enzyme activities at an interval of 10 days up to 40 days. Acid and alkaline phosphatase activities initially increased and started declining after 20 days in all the vermibed substrates. In teak leaf litter+cowdung vermicompost, acid phosphatase activity was 0.148, 0.155,       0.150, 0.119 and 0.094 m moles of phenol liberated/l respectively on 0, 10, 20, 30 and 40 days after harvesting. Similar trend was also recorded in alkaline phosphatase activity in vermicomposts during storage. The decreased level of activity of phosphatases on 40th day of storage was statistically significant.
