The correct answer is: B) Southern transitional zone.
Groundnut is a major crop in Karnataka, and the southern transitional zone is the most important region for its cultivation. This zone is characterized by its warm, humid climate and fertile soil, which are ideal conditions for growing groundnut. The southern transitional zone also has a well-developed infrastructure, including irrigation systems and transportation networks, which make it easy to grow and transport groundnut.
The northern dry zone is not as well-suited for growing groundnut because of its hot, dry climate. The coastal plains are also not ideal for growing groundnut because of their saline soil. The hilly zone is not as well-developed as the southern transitional zone, and it is difficult to grow and transport groundnut in this region.
Here is a brief explanation of each option:
- A) Northern dry zone: The northern dry zone is characterized by its hot, dry climate. This climate is not ideal for growing groundnut, which requires a warm, humid climate. The northern dry zone also has poor soil quality, which makes it difficult to grow groundnut.
- B) Southern transitional zone: The southern transitional zone is characterized by its warm, humid climate and fertile soil. These conditions are ideal for growing groundnut. The southern transitional zone also has a well-developed infrastructure, including irrigation systems and transportation networks, which make it easy to grow and transport groundnut.
- C) Coastal plains: The coastal plains are characterized by their saline soil. This soil is not ideal for growing groundnut, which requires a well-drained soil. The coastal plains also have a hot, humid climate, which can be harmful to groundnut plants.
- D) Hilly zone: The hilly zone is characterized by its rugged terrain and poor soil quality. These conditions make it difficult to grow groundnut. The hilly zone also has a cool, humid climate, which is not ideal for growing groundnut.
