“System of rice Intensification” of cultivation, in which alternate wetting and drying of rice fields is practised, results in:
  1. Reduced seed requirement
  2. Reduced methane production
  3. Reduced electricity consumption
Select the correct answer using the code given below

Explanation

The System of Rice Intensification (SRI) is an innovative rice cultivation method that emphasizes alternate wetting and drying of rice fields, which promotes healthier root systems and enhances overall crop productivity. This method leads to a reduced seed requirement as fewer seeds are transplanted per unit area, and it decreases methane emissions due to less continuous flooding, which contributes to reduced anaerobic decomposition. Additionally, the practice of SRI can lower electricity consumption because it minimizes the need for continuous pumping of water, aligning with sustainable agricultural practices that are vital for food security and environmental conservation, as emphasized in standard UPSC reference material.
