Abstract:- Studies on the effect of fortification of leaves of Terminalia arjuna with different secondary nutrients in different concentrations to tasar silkworm Antheraea mylitta  Drury revealed that secondary nutrients showed promotary effect over control in respect of cocoon character.  Among the ten treatments studied, fortification of leaves with Magnesium sulphate (2% w/v) is the most effective in improving the characters of A.mylitta. Under this treatment larval weight, cocoon weight, shell weight and silk ratio present increased by 33.26, 31.35, 61.61 & 23.03 % respectively as compared with control.
