Nutritional requirement in food consumption have direct impact on the overall growth of silkworm and also increase the larval, pupae and cocoon weight with amount of silk production. The use of natural dyes for textile fibers has become an alternative to solve issues as environmental pollution and health risks by the larvae fed with neutral red treated mulberry leaves. In the present study the silkworm Bombyx mori were fed with the concentration of Neutral red (0.05 and 0.025%) treated mulberry leaves from the 5th instar larvae. Different nutrition of silkworm is sole factor which almost augment quantity and quality of slide fortification of mulberry leaves by nutrient supplementation can be increased the quality most popularity and productivity of silk. This study was to find out the economic parameters such as larval length, larval weight, larval survivability, cocoon weight, shell weight, pupal weight and shell ratio. The observed results were statistically analysed and discussed.
