ABSTRACT

The unutilization cashew leaf litter and under utilized sugar mill waste pressmud cause environmental polution. Using cashew leaf litter (CL) and pressmud (PM) in 1:3 ratio as the basic fee substrate, the following treatdment were prepared in triplicate on basis: C-PM alone; T-CL+PM; T2 - CL+PM+GW (1:1:2); T3 - CL+PM+Urea (10mg/kg); T4 - CL+PM+ Tv (500mg/kg); T5 - CL+PM+Pp (500mg/kg); T6 - CL+PM+Tv+Pp (250mg/kg). In each treatment one kg of feed substrate were prepared in plastic tray. Ten hatchiling of E.eugeniae were cultured in each treatment and control under laboratory condition at room temperature with 60-70% moisture. One in 15 days. upto 90 days the weight of earthworms, worm growth rate and numbder of hatchlings were determined and analysed statistically. On the basis of results the efficiency of six treatment to support the growth and reproduction of E.eugeniae could be ranked in following order: T6>T2>T3>T5>T4>T1. The higher rate, weight gain, and hatchling production observed in T6, T2, and T3 could be due to the addition of nitrogen as well as contribution of nutrients because of biodegradation of cashew leaves by lignocellulolytic fungi in addition to the contribution of nutrients by pressmud
