Which one of the following crops is not cultivated under dryland farming ?
- A.Jowar
- B.Ragi
- C.Sugarcane
- D.Groundnut
Correct answer
Explanation
The correct answer is C, Sugarcane. Sugarcane needs plenty of water through a long growing season, so it is grown under irrigation or in high-rainfall areas, not as a dryland crop.
Dryland farming is practised in areas that receive less than about 75 cm of rainfall a year and have no assured irrigation. Farmers there grow hardy, drought-tolerant crops such as jowar, bajra, ragi, pulses like gram and moong, and oilseeds like groundnut, and they use moisture-saving methods such as mulching, contour bunding and farm ponds. Sugarcane, by contrast, stands in the field for 10 to 18 months and needs roughly 150 to 250 cm of water, which is why it is concentrated in irrigated tracts of Uttar Pradesh, Maharashtra and Karnataka.
Option A is wrong because jowar is a classic dryland millet. Option B is wrong because ragi, finger millet, grows well on poor, dry soils. Option D is wrong because groundnut is a major rainfed oilseed of dry regions.
Exam tip: dryland crops are millets, pulses and oilseeds; water-hungry crops are rice and sugarcane.
