ABSTRACT:

CSR2, CSR4 and CSR18 varieties of silkworms were reared by fed with M5 variety of mulberry leaves cultivated by different proportions of spentwash irrigation. Influence of SW irrigated M5 Mulberry leaves on the yields of different varieties of cocoons of silkworms at their respective maturity was investigated. It was found that the yields of CSR2, CSR4 and CSR18 were high in case of Mulberry leaves irrigated with 33% SW than raw water and 50% spentwash irrigations [the percentage yield was maximum in the case of CSR4 (26.6%) and minimum in CSR18 (19.0%) and moderate in CSR2 (22.77%)]. This concludes that the diluted (33%) spentwash irrigated mulberry leaves is most suitable for the rearing of the above varieties of cocoons, which elevates the economy of the farmers.
