Correct Option
Statement 1 is correct. The bud chip method involves preparing single-bud chips, raising them in a nursery, and subsequently transplanting the seedlings into the main field. This technique significantly reduces the quantity of seed material required for cultivation, leading to substantial savings.
Statement 4 is correct. Sugarcane can be propagated using setts derived from tissue culture. This biotechnological method enables the production of disease-free, uniform, and high-yielding planting material, which is beneficial for crop improvement and rapid multiplication.
Incorrect Options
Statement 2 is incorrect. When sugarcane setts are directly planted, multi-budded setts typically exhibit a higher germination percentage compared to single-budded setts. This is due to the presence of multiple buds, increasing the probability of successful sprouting.
Statement 3 is incorrect. Under adverse weather conditions during direct planting, single-budded setts generally have a lower survival rate. Multi-budded setts tend to survive better due to the redundancy provided by multiple buds, offering greater resilience against unfavorable environmental factors.
