With reference to agricultural zoning and agro-climatic regions in India defined by the Planning Commission, Tamil Nadu falls predominantly under which of the following classified zones?

💡 Solution & Explanation

Tamil Nadu falls primarily within the Southern Plateau and Hills Region, characterized by semi-arid to tropical monsoonal climates supporting crops like millets, cotton, oilseeds, and plantation agriculture. The East Coast Plains and Hills Region covers coastal strips and deltaic tracts where paddy cultivation predominates. Agro-climatic regional planning helps optimize cropping patterns based on soil type, rainfall distribution, and irrigation availability. Groundwater extraction forms a vital irrigation source across peninsular agrarian tracts.
