Abstract: An experiment was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to study the influence of liquid organic manures viz., Panchagavya, Jeevamruth and Beejamruth on microbial activity, growth, lycopene content and yield of tomato in the sterilized soil during kharif 2009. The rhizosphere and phyllosphere population of fluorescent pseudomonads, phosphate solubilizing microorganisms and free-living nitrogen fixers were significantly highest when all the three organic liquid manures were given followed by RDF + Beejamruth + Jeevamruth + Panchagavya at 75 DAS (days after sowing) and 160 DAS. The enzymatic activities viz., dehydrogenase, urease and phosphatase were significantly highest when all the three organic liquid manures were given at both the stages of crop growth. The plant growth and root length recorded was significantly highest with the application of RDF + Beejamruth + Jeevamruth + Panchagavya and it was found to be significantly superior over other treatments. The N, P and K concentration of plants was significantly highest in the treatment given with RDF + Beejamruth + Jeevamruth + Panchagavya. Among all the treatments, the application of Beejamruth + Jeevamruth + Panchagavya resulted in significantly highest lycopene content. The application of RDF + Beejamruth + Jeevamruth + Panchagavya resulted in significantly highest yield of tomato and it was found to be significantly superior over other treatments. The application of Beejamruth + Jeevamruth + Panchagavya was next best treatment and resulted in significantly highest tomato yield as compared to RDF alone. This study clearly brought out significant improvement in soil biological indicators such as microbial population and enzymatic activity due to combined application of liquid organic manures. There was significant improvement in the yield of tomato with the combined application of liquid organic manures with RDF.
