Study on the effect of feeding mulberry leaves raised in intercropping with legumes on silkworm Bombyx mori L.was carriedout during the year 2012 at K.V.K. Chamarajanagar. Significantly more larval weight (38.36 g/10), ERR (91.6 %) and shorter fourth (5.13 days) and fifth instar larval duration (6.92 days) and better cocoon weight (19.38 g/10 cocoons), Pupal weight (15.86 g/10) and shell weight (3.51 g/10 shells) obtained in mulberry and soybean and least shell ratio percentage (15.46), filament length (734 m) and thicker denier (2.26) was obtained in sole mulberry. Least natural incidence of flacherie (1.33 %), grasserie (1.40 %) and muscardine (2.75 %) was noticed in mulberry and soybean intercrops.
