What are the significances of a practical approach to sugarcane production known as 'Sustainable Sugarcane Initiative'? 1. Seed cost is very low in this compared to the conventional method of cultivation. 2. Drip irrigation can be practiced very effectively in this. 3. There is no application of chemical/inorganic fertilizers at all in this. 4. The scope for intercropping is more in this compared to the conventional method of cultivation. Select the correct answer using the code given below.

1. Correct. In Sustainable Sugarcane Initiative (SSI), bud chips/single-bud seedlings are used instead of large quantities of cane setts, so seed material requirement and cost are much lower.

2. Correct. SSI promotes wider spacing and efficient water management; hence drip irrigation works very effectively and saves water.

3. Incorrect. SSI is not a system of zero chemical/inorganic fertilizer use. It emphasizes better nutrient management, often integrating organic inputs, but does not prohibit chemical fertilizers altogether.

4. Correct. Because SSI uses wider row spacing, there is greater scope for intercropping than in conventional sugarcane cultivation.

Therefore, statements 1, 2 and 4 are correct.
