dc.description.abstractThe present study entitled, Organic based nutrient management in mulberry and its impact on silkworm was conducted during spring season 2019 at Division of Sericulture, SKUAST-Jammu in order to know the effect of different organic manures alone and in combination with biofertilizer (Azospirillum) on growth and yield parameters of mulberry (var. China white), rearing performance of silkworm hybrid (FC1×FC2) and other important metric traits. The results revealed that, among different treatments, application of vermicompost + Azospirillum (4.0g/plant) significantly increased mulberry growth parameters viz., plant girth (7.50 ± 0.13cm), plant height (284.67 ± 7.36cm), number of shoots per plant (15.33 ± 1.20), shoot height (146.63 ± 8.03cm), longest shoot (158.27 ± 6.71cm), internodal distance (5.00 ± 0.40cm), number of leaves per plant (1203.33 ± 60.92), fresh leaf yield (3013.00 ± 71.00g/plant), leaf area index (1.54 ± 0.02), moisture content (72.02 ± 1.05%) and moisture retention per cent after 6 hours (74.43 ± 0.01). Observations on larval traits, cocoon and post cocoon parameters of silkworm were also recorded and the results revealed positive impact in case of vermicompost @ 4kg/plant + Azospirillum (4.0g/plant) (T6) with respect to V instar 10 larval weight (46.69 ± 0.66g), larval survival per cent (97.05 ± 0.58) and shorter total larval duration (27.02 ± 0.01D:H), ERR (By wt.14.26 ± 0.01 and By No. 8987 ± 5.51), single cocoon weight (2.06 ± 0.01g), single shell weight (0.48 ± 0.00g), shell ratio per cent (23.10 ± 0.17), total filament length (1308.00 ± 9.07m), non breakable filament length (1308.00 ± 4.73m), filament size (2.50 ± 0.02d) followed by FYM @ 4kg/plant + Azospirillum (4.0g/plant) (T5), Neem cake @ 2.5kg/plant + Azospirillum (4.0g/plant) (T8), Vermicompost @ 4kg/plant (T2), Silkworm rearing waste @ 3kg/plant + Azospirillum (4.0g/plant) (T7), FYM @ 4kg/plant (T1), Neem cake @ 2.5kg/plant (T4), Silkworm rearing waste @ 3kg/plant (T3) respectively as compared to control (T9). Based on the present findings it may be concluded that, the application of vermicompost + Azospirillum (4.0g/plant) would be an advisable treatment so as to produce quality mulberry leaves and cocoon crop with improved metric traits.en_US
