With reference to the current trends in the cultivation of sugarcane in India, consider the following statements:

A substantial saving in seed material is made when ‘bud chip settlings’ are raised in a nursery and transplanted in the main field.
When direct planting of setts is done, the germination percentage is better with single-budded setts as compared to setts with many buds.
If bad weather conditions prevail when setts are directly planted, single-budded setts have better survival as compared to large setts.
Sugarcane can be cultivated using settlings prepared from tissue culture.

Which of the statements given above is/are correct ?

Statements 1 and 4 are correct. Statements 2 and 3 are incorrect.

Statement 1 is correct because bud chip settlings (using small cane pieces with just one bud grown in a nursery) significantly reduce the amount of seed cane required compared to traditional methods. Statement 4 is correct as tissue culture is a viable method for producing disease-free sugarcane planting material. Statement 2 is incorrect; traditional direct planting uses multi-bud setts (typically 2-3 buds) for better germination and survival compared to single-budded setts. Statement 3 is incorrect; larger setts with more buds and reserves are generally more resilient to adverse weather conditions than smaller single-budded setts when planted directly.

Modern techniques like bud chip technology and tissue culture propagation aim to improve the efficiency and health of sugarcane cultivation. They help in conserving planting material, reducing disease spread, and achieving better crop stands.
