- 10. Benefits of SRI 1. Higher yields – of both grain and straw 2. Reduced duration of crop cycle (by 10-15 days) 3. Less chemical inputs 4. Less water requirement 5. Less chaffy grain (%) 6. Grain weight increased without change in grain size 7. Higher head rice recovery rate 8. Withstands cyclonic gales 9. Soil health improves through biological activity
