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. Which of the statements given above is/are correct?

1. Statement 1 is correct. Using 'bud chip settlings' (small chips containing a single bud) raised in a nursery requires significantly less seed material compared to planting traditional large setts (sections of cane with multiple buds) directly in the field. This leads to substantial saving in seed material. 2. Statement 2 is incorrect. When direct planting is done, setts with many buds generally have a higher chance of successful germination compared to single-budded setts, as there are more buds available to sprout, providing insurance against individual bud failure. 3. Statement 3 is incorrect. Under bad weather conditions, large setts (with multiple buds and more stored food reserves) generally have a better chance of survival compared to delicate single-budded setts when directly planted. 4. Statement 4 is correct. Tissue culture techniques can be used to rapidly multiply disease-free planting material of sugarcane. These micropropagated plantlets (settlings) can then be hardened and used for cultivation, ensuring uniformity and health. 5. Therefore, statements 1 and 4 are correct.
