dc.description.abstractThe field experiment was conducted at Department of Sericulture, GKVK during 2020- 21 by introducing different heights of pruning to V-1 mulberry and the results revealed that, mulberry pruned at 150 cm above the ground level was recorded highest shoot height (95.60 cm), number of shoots (23.35), number of leaves (162.35) and leaf yield (479.25 g/ plant) per plant at 60 DAP. However, pruned at 30 cm significantly more moisture content (78.59 %), total chlorophyll (2.32 mg/g) content, leaf nutrient elements like N (3.90 %), P (0.58 %), K (2.04 %), Ca (1.20 %), Mg (0.13 %) and S (0.17 %) content were recorded at 30 DAP. Further, the leaf harvested from V-1 and fed to IV and V instar PM × CSR2 and FC1× FC2 hybrids revealed maximum V instar fifth day larval weight of 19.77 and 20.60 g/10 in healthy and 14.76 and 18.13 g/10 in inoculated batches where as in FC1 × FC2 the values were 31.61 and 32.45., 27.05 and 26.64 g/ 10, respectively. Further, T6 (150 cm) with bacterial inoculation revealed less larval weight reduction (11.52 and 15.63 %) in V instar inoculated batch than remaining treatments. It is vivid from the data that, bacterial percent disease outbreak was found more in the batches of silkworm fed on leaves from 60 cm above the ground level on contrary less (150 cm ) was noticed in both the hybrids. As the pruning height increased, from 30 - 150 cm the cocoon parameters were decreaseden_US
