Investigation on the Sources of Organics for Mulberry and its Impact on Quantitative Traits of the Silkworm, Bombyx mori L.

TL;DRAbstract

The experiment was conducted to know the efficacy of sources of organic manures (vermicompost, enriched
\nvermicompost, farm yard manure - FYM, coir pith compost, urban solid waste compost and biodigested slurry) on
\nmulberry (V-1 variety) under irrigated condition to meet nitrogen requirement (100%) and its influence was studied on
\neconomic performance of PM x CSR-2 silkworm during 2004-05. The study revealed that the batch of silkworms fed on
\nmulberry leaves raised by supplying 100% nitrogen (N) through vermicompost and recommended phosphorus (P) and
\npotassium (K) through chemical fertilizers recorded significantly superior effective rate of rearing, cocoon yield, cocoon
\nweight, shell weight, shell ratio, silk productivity, single cocoon filament length and fibroin contents with least larval
\nduration, disease incidence (muscardine, flacherie and grasserie), denier and sericin contents. Further, enriched
\nvermicompost + recommended P and K a
