"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:

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer: 1, 2 and 3

The system of rice intensification or SRI was first introduced in the 1980s in Madagascar in an attempt to synthesise local rice production. It is a stepwise procedure that includes four separate stages: seed management, water management, nursery change management and duration of the plantation. 

Benefits of SRI

  • Higher yields – Both grain and straw
  • Reduced duration (by 10 days)
  • Lesser chemical inputs
  • Less water requirement
  • Less chaffy grain %
  • Grain weight increased without change in grain size
  • Higher head rice recovery
  • Withstand cyclonic gales
  • Cold tolerance
  • Soil health improves through biological activity
