The experiment was conducted 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). The experiment revealed significant differences with respect to treatments. Among these, application of Vermicompost @ 4kg/plant + Azospirillum (4.0g/plant) was recorded significantly higher growth parameters (plant girth, plant height, number of shoots per plant, shoot height, longest shoot, internodal length) and yield parameters (number of leaves per plant, fresh leaf yield, leaf area index, moisture content (%), moisture retention per cent after 6 hours). Further FYM@ 4kg/plant + Azospirillum (4.0g/plant) found next best with respect to economic traits of mulberry. The results of the present study showed superiority of application of Vermicompost @ 4kg/plant + Azospirillum (4.0g/plant) after pruning so as to produce good quality mulberry leaves which in turn may improve soil health.

The present studies on the evaluation of different bivoltine silkworm (Bombyx mori L.) breeds on survival against Nuclear Polyhedrosis Virus (Grasserie), under temperate climatic conditions was carried out at College of Temperate Sericulture, SKUAST-Kashmir, Mirgund. Preliminary evaluation of ten silkworm genotypes viz., APS4, APS8, CS6, CSR2, CSR4, DUN-6, DUN-22, NB4D2, SH6 and SANISH8 revealed that APS8 and NB4D2 breed possessed highest tolerance while, CSR2 and CSR4 were highly susceptible to BmNPV Inoculation @ 20,000 PIB'S. The silkworm CSR4 showed drastic decrease in survival rate of (37.33%) in susceptible breed. However in tolerant breed APS8 recorded the survival rate of (72.67%). The maximum pupation rate of 91.36 per cent was recorded in case of NB4D2 and minimum pupation rate of 82.41 per cent was recorded in CSR2.
