The Sustainable Sugarcane Initiative (SSI) is a method of sugarcane cultivation that seeks to optimize the use of inputs such as seed, water, and nutrients while maximizing yields. It is known for its economic and environmental benefits.
Option 1 is true as SSI requires fewer seeds than the conventional method, which reduces seed cost.
Option 2 is correct as well because drip irrigation is key to SSI`s water-saving strategy. It enables efficient water use and is thus practiced effectively in SSI.
Option 3, however, is incorrect; while SSI promotes organic farming practices, it doesn`t completely disallow the use of chemical/inorganic fertilizers. The emphasis is on their reduced and efficient use, not total ban.
Option 4 is true because SSI takes less space due to the reduced plant population, which leaves more room for intercropping compared to the conventional method of cultivation.
Thus, options 1, 2, and 4 are correct, making the answer 2.
