Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Specific crop intensity index (SCII) is a derivative of cropping intensity index (CII)
Reason (R): SCII determines the amount of area time devoted to each crop compared to the total time available to the farmer

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Intensity = Use Availability. If a farmer has 1 hectare for 1 year, their "Total time available" is 365 hectare-days. SCII tells you exactly what % of those days were "busy" with a specific crop.

Answer 1

The Correct Option is A

Concept: Cropping intensity measures the number of times a crop is planted on the same field in one year. While the standard Cropping Intensity Index (CII) gives a broad farm-level view, more refined derivatives exist to analyze specific crop dynamics.

Step 1: Analyze Assertion (A).
The Specific Crop Intensity Index (SCII) is indeed a specialized metric derived from the general concepts of cropping intensity. It allows for a more granular analysis of how intensely a particular crop is being used within the cropping system. Thus, Assertion (A) is correct.

Step 2: Analyze Reason (R).
The purpose of the SCII is to quantify the "area-time" allocation. It measures how much land area is used for how long for a specific crop, relative to the total possible area-time (land size $\times$ 365 days) available to the farm manager. This explains *how* the index is derived and why it is a derivative of the general intensity concept. Thus, Reason (R) is correct and provides the logical basis for (A).
