UPSC Previous Year Question | Prelims GS | 2020

With reference to the current trends in the cultivation of sugarcane in India, consider the following statements: 1. A substantial saving in seed material is made when 'bud chip settlings' are raised in a nursery and transplanted in the main field. 2. When direct planting of setts is done, the germination percentage is better with single-budded setts as compared to setts with many buds. 3. If bad weather conditions prevail when setts are directly planted, single-budded setts have better survival as compared to large setts. 4. Sugarcane can be cultivated using settlings prepared from tissue culture.

  1. 1 and 2 only
  2. 3 only
  3. 1 and 4 only
  4. 2, 3 and 4 only

Answer

Correct Answer

1 and 4 only

Explanation

Bud-chip settlings save a large amount of seed cane, and tissue-culture settlings are used to plant sugarcane. Single-budded setts do not germinate better or survive better in bad weather than multi-budded setts, so statements 2 and 3 are wrong.
