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
In the light of the above statements, choose the most appropriate answer from the options given below :
The Assertion (A) states that the Specific Crop Intensity Index (SCII) is a derivative of the Cropping Intensity Index (CII). This is fundamentally correct. The CII typically measures the ratio of the total cropped area to the net sown area over a season. SCII is a more refined metric that builds upon the CII concept, often incorporating details about individual crops or the temporal allocation of land use.
The Reason (R) explains that SCII determines the amount of area-time devoted to each crop relative to the total time available to the farmer. This definition accurately describes the function of a specific crop intensity index. It provides insight into how effectively the land's time resource is utilized for cultivating different crops throughout the available period, offering a nuanced view of cropping patterns.
Reason (R) provides the core reason why SCII is considered a derivative or a more advanced form of CII, as stated in Assertion (A). The concept of 'area-time devotion' is the key refinement that distinguishes SCII. This temporal aspect is intrinsic to the 'specific' nature of SCII, making the farmer's time allocation across specific crops the basis for its calculation and its relationship to the broader CII.
Therefore, both statements are accurate, and the explanation provided in Reason (R) correctly clarifies the nature and purpose of SCII, explaining why it's derived from and expands upon the basic CII concept.
