Sericulture is one of the most promising agricultural crops in India and played a vital role in increasing the income of the farmers, the present experiment was conducted at Department of Sericulture, UAS, GKVK, Bengaluru during the year 2020-21 by introducing different pruning techniques to the V-1 mulberry variety. For this study six treatments were laid out in RCBD with four replications. 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 days after pruning (DAP). Further, the leaf harvested from V-1 mulberry and fed to PM × CSR2 silkworm hybrid, revealed maximum V instar fifth day larval weight of 19.77 g/10, effective rate of rearing (ERR %, (98.50 %)), spinning percentage (97.75 %), silk productivity (cg/day) (2.24), cocoon weight (7.46 g/5 cocoon), shell weight (1.26 g/5), shell ratio (17.32 %), were in 30cm above the ground level pruned treatment followed by 45 cm above the ground level. As the pruning height increased, from 30-150 cm the cocoon parameters were decreased.
