Abstract:
Field experiments were conducted to evaluate the organic sources of nutrients and Panchagavya spray on
the biochemical changes and yield of maize-sunflower-green gram cropping system. The experiment
consisted of nine treatments comprising six treatments of organic sources of nutrients with and without
Panchagavya (blend of five products obtained from cow) foliar spray; two treatments were recommended
dose of fertilizers (RDF) with and without recommended foliar spray (RFS) and one control (neither
manured nor fertilizer applied). The study revealed that increased soluble protein content and NRase
activity of maize, sunflower and green gram with BGS and it was comparable to RDF, RFS, RDF and biogas
slurry (BGS) treatments. Higher yield of maize and sunflower were recorded under BGS with
Panchagavya. Grain yield of green gram was higher under recommended fertilizer treatments but it was
comparable to BGS with Panchagavya-. Among all the organic sources tried, BGS+Panchagavya spray
proved to be a better source than others.
