The experiment was conducted to know the efficacy of sources of organic manures (vermicompost, enrichedudvermicompost, farm yard manure - FYM, coir pith compost, urban solid waste compost and biodigested slurry) onudmulberry (V-1 variety) under irrigated condition to meet nitrogen requirement (100%) and its influence was studied onudeconomic performance of PM x CSR-2 silkworm during 2004-05. The study revealed that the batch of silkworms fed onudmulberry leaves raised by supplying 100% nitrogen (N) through vermicompost and recommended phosphorus (P) andudpotassium (K) through chemical fertilizers recorded significantly superior effective rate of rearing, cocoon yield, cocoonudweight, shell weight, shell ratio, silk productivity, single cocoon filament length and fibroin contents with least larvaludduration, disease incidence (muscardine, flacherie and grasserie), denier and sericin contents. Further, enrichedudvermicompost + recommended P and K and recommended FYM and NPK found next best with respect to the economicudtraits of silkworm. However, these characters were inferior with the group of silkworms fed on mulberry grown by theudapplication of coir pith compost and recommended P and K. The details are discussed.
