- Abstract
Agriculture is one of the prominent sectors in Tamil Nadu providing livelihood support to 56% of the population. The state accounts 7% of the country's population and 4% of water resources of the country. About 56% of the total cropped area of the state is under irrigated while around 44% of the area is under dry land farming. The contribution of agriculture in SGDP is 13% in 2006-07. The principal crops raised in the state comprise of food crops like paddy, millets, pulses and oilseeds and non-food crops like cotton and sugarcane. The total cropped area and production of principal crops depend on quantum and spread of precipitation and availability of ground water. Agricultural sector witnessed deceleration from 1990's onwards since the growth in agriculture face major constraints such as growing water scarcity, increasing land degrading, declining farm sizes and rise in cost of labour. Agricultural lands have also come under increasing pressure due to rapid urbanization. Moreover, the crop diversification underwent significant changes in the last two decades in area, productivity, and production in agricultural sector. In Tamil Nadu agricultural sector underwent significant transformation especially the transition from the traditional crops to the commercial crops which envisages the prominent scope for crop diversification. The measurements of the crop diversification generally used are the Herfindal Index, Entropy Index, & Modified Entropy Index. This paper used Herfindal Index & Entropy Index for measuring the diversification of crops in Villupuram District from 1998 to 2008.
