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 singlebudded 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.

Which of the statements given above is/are correct?

Select an option to attempt

Explanation

Statement 1 is correct: The bud chip method involves raising sugarcane settlings in a nursery before transplanting them into the main field. This method reduces seed material requirements by using only the bud instead of the entire sett, leading to cost savings and better efficiency.

Statement 2 is incorrect: Multi-budded setts generally have a higher germination percentage than single-budded setts. Single-budded setts may face more difficulty in germination compared to setts with multiple buds, which provide better shoot emergence.

Statement 3 is incorrect: Under adverse weather conditions, large setts have better survival rates because they store more nutrients and moisture. Single-budded setts are more vulnerable to unfavorable conditions and may have lower survival rates.

Statement 4 is correct: Tissue culture techniques are successfully used for sugarcane cultivation. Settlings prepared from tissue culture help in producing disease-free, high-yielding plants and allow rapid multiplication of quality planting material.

Hence, option C is the correct answer.
