Field experiment was carried out during June 2010 – March 2011 at Agricultural Research Station, Bhavanisagar, Tamil Nadu, to determine the effect of organic sources of nutrients (Wellgro soil, wellgro pellets, wellgro grains and Farm yard manure) on soil fertility and quality parameters of turmeric. The results revealed that soil fertility characters (soil organic carbon content and microbial population) were enhanced with application of 100 % Recommended Dose of Fertilizer (RDF) + 40 % of total weight of chemical fertilizer as wellgro soil (140 kg ha -1 ) and it was followed by 100 % RDF + 40 % wellgro grains (140 kg ha-1 ). The quality parameters viz., curcumin, oleoresin and essential oil content were also regimed supreme by application of 100 % RDF + 40 % of total weight of chemical fertilizer as wellgro soil (140 kg ha -1 ).
