Benefits of SRI Seed requirement 75% less
Water requirement 45-50 % less with greater resistance to water stress
Fertilizer requirement 25%-40% less
Head rice recovery 71-74%
Maturity period Uniform
Duration 8-10 days less
Yield 20%-25% more
Root systems and tillering
Strong & profuse, resulting in lodging resistance
Pest & disease management
Development of resistance against foot rot in basmati rice
Soil health Increase in microbiological activities
Quality of grain Better
