ABSTRACT:A survey on the knowledge of sericulturists on adoption of organic farming practices in Chickballapur district of Karnataka revealed that majority (44.16%) of the sericulturists had low knowledge about organic farming practices followed by medium (35.83%) and high (20.00%) knowledge, respectively. With respect to the recommended individual organic farming practices, majority of sericulturists had correct knowledge about application of FYM (88.33%) and use of Ankush (82.50%). None of the sericulturists (100%) had correct knowledge about use of Tank silt, Seri-VAM, Seri-nematoguard, FYM + Neem Cake +Marigold intercrop in mulberry and use of Nysolynx thymus to control uji pest. Only negligible percentage of sericulturists had correct knowledge about use of Seri-bioguard (0.83%), Sunhemp as green manure (1.67%), Seri-mildew guard (1.67%), Seri-comporich (2.50%) and Azatabacter biofertilizer (2.50%). Out of 11 variables studied, four variables viz., family size, land holding, area under mulberry and social participation had positive and significant relationship with knowledge of sericulturists. All these variables have explained only 72.60 per cent variation in knowledge of sericulturists. Hence, it is necessary to intensify extension activities like group discussion meetings, training programmes, field visits, demonstrations etc., to enhance the knowledge of the sericulturists on organic farming practices. This will result in desired level of adoption of organic farming practices among sericulturists.
Key words: Sericulturists, Knowledge, Organic farming practices. Extension activities

ABSTRACT:In order to protect the endangered wild animal species, to maintain the biodiversity, controls the poaching and finally to lock up the criminals behind bars, it is necessary to develop accurate and authentic methods for identification of wild animals. The present work has been undertaken to verify the utility of species specific primer for identification of various species of carnivore animals. The DNA from blood samples of tiger, leopard, wolf and jackal were isolated by alcohol-chloroform method and subjected to PCR assay using species specific primers. The results of the present study indicated that the species specific primer would be useful in identification of carnivore animal species.
Key words:carnivore, DNA, PCR, primer sequence.

ABSTRACT:Varying levels of chemical fertilizers i.e. NPK and vermicompost significantly influenced the yield attributing characters and growth and biomass production in cabbage (Brassica oleraceae var.capitata) cv. Pride of India. There were six treatments (T₁: control i,e without any fertilizer; T₂: NPK @140:140:140 kg/ha; T₃: NPK@105:105:105 kg/ha + Vermicompost @ 1 ton/ha; T₄: NPK@70:70:70 kg/ha + Vermicompost @ 2tons/ha; T₅: NPK@35:35:35 kg/ha + Vermicompost @ 3 tons/ha; T₆: Vermicompost @ 4 tons/ha) each replicated four times. A maximum of 58.67% increase in yield over control was observed in a combined application of NPK and vermicompost in halves of their recommended doses.
Key words:NPK, Vermicompost, recommended dose, Brassica oleraceae var. capitata, yield.
