چکیده    The co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteriaand arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. the data revealedthat maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha)uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculatedtreatments irrespective of different levels and sources of fertilizer. significantly higher effective rate ofrearing (err, 95.33%), single cocoon weight (2.06 g) and single shell weight (0.44 g) were recorded byfeeding silkworm with the leaves harvested from the treatment t8 receiving 175 kg nitrogen and 70 kgphosphorus/ha/yr with rock phosphate as a source of phosphorus and co-inoculated with beneficialmicro-organisms. maximum filament length of 936.33 meter per cocoon and reel ability of (86%) wasalso recorded in the treatment t8.
