Potential Zones of Turmeric and Coriander Cultivation in Tamilnadu

The research paper attempts to delineate district level efficient cropping zones of turmeric and coriander over Tamilnadu (2001-2015) after analysing the trend on cultivation of both the crops at state level (1985-2015). Trend analysis of area and production revealed that both were increasing for turmeric and decreasing for coriander; but productivity had a downscale with turmeric and an upscale with coriander. Delineation of Efficient Cropping Zones of Coriander resulted in Tiruchirappali, Perambalur, Virudhunagar, Cuddalore, Ramanathapuram and Thoothukudi districts as better performers, whereas, Erode, Namakkal, Coimbatore, Salem and Dharmapuri disricts were excelling in Turmeric cultivation.
