The tropical silkworm Antheraea mylitta is commercially exploited for it immense economic importance in sericulture industry, which feeds mainly on the leaf of Arjun, Asan and Sal and spin cocoon. The quality of silk depends upon the quality and quantity of the leaf they feed on. So, keeping this in mind the present study was carried out using two different organic manure i.e. Sheep and Poultry manure along with biofertilizer and inorganic manure. The different treatment showed significant improvement on the experimental plant. The moisture contained of the leaf ranged from 60.788-79.077%. While the crude protein ranged from 2.572-11.124% and total carbohydrate ranged from 38.489-158.307 mg g-1. The nutrient content of leaf i.e. N% ranged from 0.4177-1.8098% with highest in K10 (1.764%). The phosphorus per cent ranged from 0.0486-0.4611% with highest (0.45%) in K11 and the potassium per cent ranged from 0.7435-1.8504% with highest in K9 (1.8%). The dry matter were found to be ranged from 114.13-486.469 g/plant with highest in the leaf of K8(469.56g).

The present study was conducted to investigate the effect of Integrated Nutrient Management practices on the different parameter of Arjun leaf the primary host plant of Antheraea mylitta D. Eleven different combination with three replication were laid out in Randomized Complete Block Design at the field of Research Extension Centre, Kapistha. The obtained results showed that morphological, Physiological and Biochemical parameter of Arjun leaf showed significant difference. The Arjun leaf length was recorded highest in K11 (17cm) was on par with K9 (17cm). Highest leaf breadth was recorded in K10 (6.2cm) was applied with 75%RDF+Poultry manure+ AB+PSB. Leaf weight was recorded highest in K7 (2.84g), lowest in K1(1.21g). Number of leaves was recorded highest in K6 (1816) over the control. The leaf yield was recorded highest in K11 (3735). Leaves dry matter production was highest in K8 (469.56g) over the control. Relative water content was highest in K5 (87.3%). The initial Electrical Conductivity was recorded highest in K9 (0.037dSm-1) and after 10 min EC was found to highest in K9 (0.111dSm-1). The Chlorophyll ’a’ was recorded highest in K9 (3.39), Chl’b’(2.36)and total chlorophyll in K9(5.75) was recorded highest. The result were found significant due to effect of INM practices which provided the nutrients element needed by plants.
