“The crop is subtropical in nature. A hard frost is injurious to it. It requires at least 210 frost-free days and 50 to 100 centimeters of rainfall for its growth. A light well-drained soil capable of retaining moisture is ideally suited for the cultivation of the crop.” Which one of the following is that crop?
(a) Cotton · (b) Jute · (c) Sugarcane · (d) Tea
उत्तर और व्याख्या · explanation in English
Answer: (a) कपास
The clue that decides it is '210 frost-free days': NCERT gives this requirement for cotton, a kharif crop that needs high temperature, light rainfall and bright sunshine and dislikes frost.
- ✓ (a) Cotton needs high temperature, light rainfall or irrigation, 210 frost-free days and bright sunshine, and takes 6 to 8 months to mature.
- ✗ (b) Jute needs high temperature and well-drained fertile flood-plain soil renewed every year, and is grown in West Bengal, Bihar and Assam; there is no 210-day frost-free rule.
- ✗ (c) Sugarcane wants hot, humid weather at 21°C to 27°C with 75 to 100 cm of rainfall, and needs irrigation where rainfall is low.
- ✗ (d) Tea needs warm, moist, frost-free weather and deep, humus-rich, well-drained soil, and is a plantation crop of humid hill and plain areas.
Remember · '210 frost-free days' is cotton's signature requirement; also high temperature, light rain and bright sunshine.
