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 ?

Describes transplanting in paddy as a practice that improves survival and yields by raising seedlings in a nursery and then transplanting them.

A student could analogously ask whether transplanting sugarcane settlings would similarly increase survival and thus reduce the amount of seed cane needed per hectare compared with direct planting.

Gives the specific environmental requirements for good bud-sprouting (moist soil, temperature range), which affects success of nursery-raised buds.

A student could compare these requirements with regional climate maps to judge where nursery-raised bud chips would reliably establish and thus potentially save seed material.

Notes that sugarcane requires manual labour from sowing to harvesting, implying labour costs and practicality matter when adopting nursery/transplant methods.

A student could weigh likely labour inputs for nursery/transplant versus direct set planting to infer whether seed savings would be offset by higher labour (affecting adoption and net seed savings).

States that extension of irrigation and infrastructure has expanded area under sugarcane, implying that availability of water/irrigation affects cropping practices and the feasibility of techniques like transplanting.

A student could map irrigated areas against regions practising transplanting-like methods to see where nursery transplant would be practical and where seed savings might be realized.

Identifies sugarcane as largely an irrigated, tropical/sub-humid crop concentrated in certain states, providing spatial context for where nursery methods might be trialed.

Using this state-level distribution, a student could focus analysis on major sugarcane states (e.g., Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu) to check local experiments or extension recommendations about bud chip transplanting and seed use.
