Cropping intensity in India is calculated by which of the following?
- A.Net sown area divided by gross cropped area into 100
- B.Gross cropped area divided by net sown area into 100
- C.Net sown area divided by reporting area into 100
- D.Gross irrigated area divided by gross cropped area into 100
Correct answer
Explanation
The correct answer is B, gross cropped area divided by net sown area into 100. The ratio tells how many crops the sown land carries in an agricultural year, so a value of a hundred would mean a single crop everywhere and the Indian figure of about 140 per cent means that a large part of the land bears a second crop, mainly where irrigation and short duration varieties allow it. Option A inverts the formula and would always give a value of a hundred or less, which cannot measure multiple cropping. Option C is the formula for the share of net sown area in the reporting area, roughly 46 per cent for India, a different indicator. Option D is the irrigation intensity or the share of irrigated area, which measures the spread of irrigation rather than the number of crops taken.
