Curcuma longa (Zingiberaceae) is known for its uses in medicine, cosmetics, food 
flavouring and textile industries. The secondary metabolites of turmeric like 
essential oil, oleoresin and curcumin are important for its multipurpose uses. 
These traits of turmeric vary from place to place due to the influence of 
environment, soil and agro-climatic conditions. Here, we analyzed turmeric from 
different agroclimatic regions for influence of various factors on its growth 
and yield of important phytochemicals. A high curcumin yielding cultivar i.e., 
Roma was collected from high altitude research station, Koraput (HARS) and 
planted in nine agroclimatic regions of Odisha. Analysis of soil texture, pH, 
organic carbon, micro and macro nutrients were done from all the studied zones 
up to 2nd generation. Plants grown in their released station i.e., Eastern Ghat 
High Land showed 5% of curcumin and were taken as control. Plants grown in 
different agroclimatic zones showed a range of 1.4-5% of curcumin and 0.3-0.7% 
of rhizome essential oil and 0.3-1% of leaf essential oil content. Gas 
chromatography and mass spectra analysis showed tumerone and alpha phellandrene 
as the major compounds in all the zones with 10-20% variation. The present study 
will be immensely helpful for standardization and management of environmental 
and ecological factors for high phytochemical yield in turmeric plant.
