Optimum elements dosages i.e., 02.%, 0.3%, 0.1%, 0.1%, 0.15% and 0.5% of various minerals i.e., N, P, K, Ca, Mg and Cu respectively in various combinations were studied on larval development and silk production of Bombyx mori L. The rearing of silkworm larvae was restricted to chopped tender and green mulberry leaves treated with different concentrations. The results revealed that mineral nutrients have not affected the yield component significantly but have also presented better food consumption, body weight, co- efficient of utilization and larval development as well. However, of all the test treatments T11 where the offered mulberry leaves were treated with 0.2% N + 0.3% K + 0.1% Ca + 0.1% P + 0.15% Mg + 0.5% Cu concentration gave the best results.
