Benefits of the System of Rice Intensification
Question
"System of Rice Intensification" of cultivation, in which alternate wetting and drying of rice fields is practised, results in: Select the correct answer using the code given below:
- 1.
Reduced seed requirement
- 2.
Reduced methane production
- 3.
Reduced electricity consumption
Options
1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3
Explanation
All three outcomes are correct. The System of Rice Intensification (SRI) uses younger seedlings spaced wider apart, drastically reducing seed requirement. Its "alternate wetting and drying" method breaks the anaerobic cycle, drastically reducing methane production. Pumping less water directly translates to reduced electricity consumption for irrigation pumps.
