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. The Sustainable Sugarcane Initiative (SSI) promotes the use of bud chips or single-budded setts/seedlings, which drastically reduces the quantity of seed material required compared to the conventional method of cultivation using 3-budded setts. This leads to a lower seed cost. 2. SSI involves wider spacing between sugarcane plants (e.g., 5x2 feet). This spacing makes the system highly amenable to the efficient use of drip irrigation, optimizing water use. 3. Statement 3 is incorrect. SSI emphasizes Integrated Nutrient Management, which includes optimizing the use of chemical fertilizers based on soil testing and encouraging organic manure/biofertilizers. It aims to reduce reliance on chemicals but does not mandate a complete absence of chemical/inorganic fertilizers. 4. The wider spacing adopted in SSI provides ample space between rows, creating a significant scope for raising short-duration crops as intercropping during the initial phase of sugarcane growth. This provides additional income and enhances farm biodiversity compared to densely planted conventional fields. Therefore, statements 1, 2, and 4 are correct significances of SSI.
