Question

"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:

Accepted Answer

All three statements about the System of Rice Intensification (SRI) are correct:

1. SRI uses significantly fewer seeds compared to conventional rice cultivation — typically 2 kg per acre versus 30-40 kg, as seedlings are transplanted individually at wider spacing.

2. SRI's practice of alternate wetting and drying reduces the duration of anaerobic conditions in paddy fields, which reduces methane production.

3. SRI requires less water due to alternate wetting and drying, which reduces the need for pumping water and consequently reduces electricity consumption.

Therefore, all three statements (1, 2 and 3) are correct.
