"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:
1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3
Solution
SRI uses fewer seedlings per hill (less seed), alternate wetting-drying reduces anaerobic conditions hence methane, and reduced pumping/irrigation reduces electricity consumption. All three benefits apply.
