Step 1: Understanding the Concept:
The Indian Council of Agricultural Research (ICAR) operates a network of national research institutes, directorates, and bureaus across the country.
Each institute is situated in a region strategically linked to its research mandate (such as sugarcane in Uttar Pradesh or soil science in Madhya Pradesh).
Step 2: Detailed Explanation:
Let us match each national agricultural institute to its headquarters location:
1. CIPHET (Central Institute of Post-Harvest Engineering and Technology) (A): This institute conducts research on post-harvest processing, value addition, and agricultural waste management.
It is located in Ludhiana, Punjab.
Thus, A matches with IV.
2. CSWCRTI (Central Soil and Water Conservation Research and Training Institute) (B): This institute, now reorganized as the Indian Institute of Soil and Water Conservation (IISWC), conducts research on soil erosion control and watershed management.
It is located in Dehradun, Uttarakhand.
Thus, B matches with III.
3. IISS (Indian Institute of Soil Science) (C): This institute focuses on soil chemistry, fertility, and biology.
It is located in Bhopal, Madhya Pradesh.
Thus, C matches with I.
4. IISR (Indian Institute of Sugarcane Research) (C): This institute focuses on sugarcane cultivation, protection, and processing technologies.
It is located in Lucknow, Uttar Pradesh.
Thus, D matches with II.
Combining these matches: A-IV, B-III, C-I, D-II.
This matches Option 4.
Step 3: Final Answer
The correct matching of institutes to their locations is A-IV, B-III, C-I, D-II.
