Description 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.
