Step 1: Understanding the Concept:
This question focuses on the historical implementation of the Taungya system in Karnataka (formerly Mysore State) during the colonial era.
Step 2: Detailed Explanation:
The Taungya system (locally known as "Kumri" in parts of Southern India) was introduced to restock degraded forest lands at low cost.
In Karnataka, the system was first implemented in 1906.
The forest department used it to establish valuable plantations of Teak (Tectona grandis) and Sandalwood (Santalum album).
Sandalwood is a hemiparasite that requires host plants for healthy growth, making it well-suited for integrated agroforestry systems.
Under this system, farmers planted agricultural crops alongside young teak and sandalwood saplings, providing weed control and protection while utilizing the soil between tree rows.
Step 3: Final Answer:
In Karnataka, the Taungya system was first practiced in Teak and Sandal plantations.
This corresponds to Option (B).
