This paper explore spatial and temporal dimensions of farm diversification of Cauvery Delta Zone (CDZ) for 20 years. In addition, it focuses on percentage of deviations from average area under cultivation of major crops in CDZ. Paddy is the major crop cultivated in CDZ. It accounted for nearly 65 percent of the gross cropped area. Recently farmers in the CDZ are shifting from paddy to diversified crops. Hence to examine this issue the study was taken up. The major districts comes under CDZ such as Trichy, Tanjore, Thiruvarur, Nagapatinam, Ariyalur and Cuddalore districts were taken for the study. Secondary data were collected from Season and Crop Report of Tamil Nadu from 1996 to 2016. Among various Crop diversification index, Herfindhal Index, Simpson Index, Entropy Index, Modified Entropy Index and Composite Entropy Index were taken for the present study. The area of pulses and cotton increased among all the districts of CDZ, but the area under water intensive requirement crops like sugarcane and banana area have decreased.
