- Sugarcane can be cultivated using settlings prepared
from tissue culture. Which of the statements given above is/are correct?
Explanation
The correct option is 1 and 4 only.
Explanation: Statement 1 is correct as 'bud chip settings' allow for efficient use of seed material, facilitating higher density planting and resulting in better resource utilization. Statement 4 is accurate as tissue culture techniques enable the production of disease-free, uniform sugarcane plantlets, enhancing yield potential. Conversely, Statements 2 and 3 are incorrect; while single-budded setts may germinate well, the survival rate in adverse conditions can often favor larger setts due to their nutrient reserves. Understanding these cultivation techniques aligns with sustainable agricultural practices emphasized in UPSC-prepared material.
