Abstract
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 ).
Key words : Turmeric, wellgro formulations, soil fertility characters, quality parameters.
