Explanation: Kerala, a state in southern India, is known for its diverse topography and agricultural practices. The state can be divided into several distinct regions based on elevation and climate, each suitable for different types of crops. The High Midland Plains, which are the correct answer, are located at an elevation of about 600 to 1,500 meters above sea level. This region is characterized by its cooler temperatures, well-drained soils, and moderate rainfall, making it ideal for the cultivation of crops like Rubber, Pepper, and Tapioca.
Rubber, a major cash crop in Kerala, requires a specific set of climatic conditions to thrive. It needs a warm and humid climate, but not excessively hot, and well-drained soils to prevent waterlogging. The High Midland Plains provide these conditions, with temperatures that are cooler than the lowlands, which helps in maintaining the health of the rubber trees.
Pepper, another important crop, is also well-suited to the High Midland Plains. Pepper vines require a warm and humid climate, but they also need well-drained soils to prevent root rot. The cooler temperatures in the High Midland Plains help in reducing the incidence of pests and diseases, which can be more prevalent in warmer, low-lying areas.
Tapioca, or cassava, is a root crop that is widely cultivated in Kerala. It requires well-drained soils and moderate temperatures to grow well. The High Midland Plains provide the necessary conditions for tapioca cultivation, with soils that are not prone to waterlogging and temperatures that are cooler than the lowlands.
In contrast, the other options are not suitable for these crops. The Backwaters, which are low-lying areas with brackish water, are not conducive to the cultivation of Rubber, Pepper, and Tapioca due to the high salinity and poor drainage. The Low Midland Plains, while suitable for some crops, do not provide the cooler temperatures and well-drained soils required for these specific crops. The High Coastal Belts, which are characterized by high humidity and proximity to the sea, are not ideal for these crops due to the higher temperatures and potential for waterlogging.
Understanding the specific requirements of these crops and the climatic and soil conditions of different regions in Kerala is crucial for successful agricultural practices. The High Midland Plains, with their cooler temperatures and well-drained soils, are the most suitable region for the cultivation of Rubber, Pepper, and Tapioca in Kerala.
