Post-cocoon parameters of silkworm as influenced by feeding of mulberry leaf obtained by application of n through different sources of organic manures and inorganic fertilizers

An experiment was conducted out to study the post-cocoon parameters of silkworm, Bombyx mori L. as influenced by feeding of leaf obtained by the application sources of N through organic manures and inorganic fertilizers. Significant differences were excerted with respect to feeding schedules, treatments and interactions. Among FS2 (Chawki worms fed with S36 leaf + Late age worm fed with M5 leaf) T12 (recommended 20 tonnes of compost + 300: 120: 120 kg of NPK / ha / year through fertilizer) contributed maximum with respect to filament length (937.25 and 948.39 m) and lower denier was accounted as (2.65 and 2.62). However, the interaction effect was found to be significant towards filament length in FS2T11 (FS2- chawki worms fed with S36 leaf + Late age worm fed with M5 leaf, T11 combination of Bio-fertilizers 10 kg each of Azospirillum + Aspergillus awamori/ha/yr + 20 % recommended N through each of Compost, Green manure (Glyricidia maculata), Oil cake (Castor cake), vermicompost and fertilizer remaining PK through fertilizer) (1045.62 m) and lower denier recorded in FS2T11 (2.39) respectively.
