In India, there are _____ Agro-eco regions and _____ Agro-eco subregions.
Show Hint
Be careful not to confuse the ICAR-NBSS&LUP classification (20 Agro-ecological Regions) with the Planning Commission's classification, which divides India into 15 Agro-climatic Zones.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Agro-ecological zoning is the division of a land area into smaller units based on similar climatic conditions, soil types, and length of growing period (LGP).
This classification is critical for planning agricultural and agroforestry practices suited to local conditions.
Step 2: Detailed Explation:
In India, the tiol Bureau of Soil Survey and Land Use Planning (NBSS&LUP) of the Indian Council of Agricultural Research (ICAR) developed a comprehensive agro-ecological classification.
By integrating parameters such as physiography, soils, bio-climate, and length of growing period, the NBSS&LUP classified the country into:
• 20 Agro-ecological Regions (AERs): These are broad geographic regions sharing macro-climatic and physiographic features.
• 60 Agro-ecological Subregions (AESRs): These are finer subdivisions within the 20 main regions, refined to account for localized soil and moisture variations.
This 20 and 60 classification remains the standard reference for land-use planning and agricultural research in India.
Step 3: Fil Answer:
The correct option is (A).

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
