Influence of Nutrition on Growth and Yield of G4 Mulberry Variety (Morus alba L.) and Bio-assay of Multivoltine Silkworm, Pure Mysore in Southern dry Zone of Karnataka, India

The experiment was carried out during 2019-20 at P-2 Pure Mysore Multivoltine Basic Seed Farm (BSF), National Silkworm Organisation, Nagenahalli, Karnataka to know the effect of nutrient management on growth and yield G4 mulberry variety its subsequent bioassay multivoltine silkworm, Mysore. garden (three years old) with planted in paired row system used for seven treatments three replications. parameters (average 5 crops) viz., plant height, number branches per plant, lowest leaf 100g weight, weight individual leaf, 100 fresh ha-1were significantly highest (134.6 cm, 14.0, 24.0, 4.18g, 384g, 800g 55.55 Mt) application % RDF, poshan spray vermicompost at5 t/ha/year. results bio-assay five rearings) also showed superiority forweight 10 full grown larvae (27.2 gm), single cocoon (1.27g), shell (0.18g), ratio (14.25%), ERR (95.00%) pupation (92.00%), cocoons/kg (787) dfls (52.10 kg) treatment having t/ha than other treatments. Combined organic inorganic sources nutrients increased productivity subsequently better performance seed parameters.
