The Planning Commission divided India into how many agro-climatic zones for agro-climatic regional planning?
- A.8
- B.15
- C.20
- D.60
Correct answer
Explanation
The correct answer is B, 15. In 1988 the Planning Commission adopted a division of the country into fifteen agro-climatic zones so that crops, irrigation, credit and research could be planned for areas that are uniform in rainfall, temperature, soil and cropping pattern. Option A, eight, is the older and broader grouping used by the Indian Council of Agricultural Research. Option C, twenty, is the number of agro-ecological regions delineated by the National Bureau of Soil Survey and Land Use Planning, which added soil type and the length of the growing period to climate. Option D, sixty, is the number of agro-ecological sub-regions into which those twenty regions were further divided. Since all four numbers belong to this topic, learn each with the body that fixed it rather than as a bare figure.

- A.Current fallow
- B.Barren and unculturable waste
- C.Culturable waste land
- D.Permanent pasture

This head covers land that could be cultivated but has lain unused for more than five years, usually because it has become saline, waterlogged, eroded or short of water, and bringing it back into use is a standing aim of land reclamation programmes.

- A.Gross cropped area
- B.Net sown area
- C.Current fallow
- D.Land put to non-agricultural uses
Show answer
Gross cropped area is a derived measure, not a land use head: it counts a field as many times as it is cropped in an agricultural year, so the same hectare can appear twice or thrice, and it is used with net sown area to calculate cropping intensity.
