Which agro-climatic region in Kerala is specifically recognized for major rubber cultivation due to its rolling topography, humid tropical climate, and well-drained lateritic soils?

💡 Solution & Explanation

The Midland zone of Kerala, locally known as Idanad, is ideally suited for extensive rubber cultivation due to its rolling lateritic terrain, warm humid tropical climate, and deep well-drained soils. Other regions such as Kuttanad feature waterlogged paddy cultivation below sea level, whereas the high-range hill zone is better suited for tea and cardamom plantations. Rubber is a major commercial cash crop that thrives under high rainfall and consistent temperatures typical of peninsular equatorial margins.
