Description An experiment was conducted during 2015-17 by application of 50% N through
SPB + 50% N + recommended dose of P & K/ha/year through chemical fertilizers (T6)
recorded highest major nutrients content (available N, P2O5 and K2O of 286.50, 50.18
and 186.32 kg/ha) in soil, highest mulberry growth (plant height of 163.72cm), leaf yield
(1005.37g/plant) and quality parameters like leaf moisture (74.26 %), total chlorophyll
(2.45mg/g), crude protein (20.16%), total soluble protein (12.02%) and total soluble
sugar (13.12%). Further, significantly higher silkworm rearing parameters such as,
mature larval weight (38.63g/10), less fifth instar larval duration (156.10 hours), total
sugar (2.47 %), lipid (2.98 %), highest ERR (98.80%), lower disease incidence (1.20%)
and cocoon parameters like maximum single cocoon weight (1.88g), shell weight (0.30g),
shell ratio (15.95%), cocoon filament length (915.70m), least denier (2.29), fibroin
(20.85μg/ml) and sericin (11.86μg/ml) content were recorded when silkworm fed with
mulberry leaves of T6 treatment.
Significantly higher mulberry growth (plant height of 158.81 cm), leaf yield
(1047.92 g/plant) and quality parameters like higher leaf moisture (74.33), total
chlorophyll (2.58 mg/g), total sugars (13.22 percent), total soluble protein (12.18 percent)
and crude protein (21.14 percent) were recorded in V1 variety sprayed with SPP @ 2
percent + RDF + 20 MT FYM/ha/year (T6) at 60th day after pruning. Further,
significantly higher silkworm rearing parameters like mature larval weight (38.78g/10),
fifth instar larval weight (38.78g/10), less fifth instar larval duration (156.58 hours) , total
sugar (2.52 %), lipid (3.04 %), lesser disease incidence (0.89 %), higher effective rate of
rearing (99.10 %) and cocoon parameters like maximum single cocoon weight (1.92 g),
shell weight (0.31 g), shell ratio (16.14 %), cocoon filament length (922.14 m), lowest
denier (2.27), fibroin (21.09 μg/ml)and sericin (12.02 μg/ml) respectively were recorded
when silkworm fed with mulberry leaves of T6 treatment.
