SYSTEM OF RICE INTENSIFICATION (SRI) AND REDUCTION OF IMPACTS OF INORGANIC INPUTS ON COASTAL WATERS
UNDP-GEF Project ‘’ Mainstreaming Coastal and Marine Biodiversity Conservation into Production sectors in Sindhudurg Coast, Maharashtra, India
SRI is a farming practice which originated in Madagascar and is being successfully practiced world over, achieves 30 to 70% increased yield over traditional practice of rice cultivation with liberal
organic input and reduced usage of inputs including Seed, Fertilizer, Labour and Water.
Implication of SRI in Mainstreaming Coastal & Marine Biodiversity Conservation in Agriculture: Reduction in eutrophication of coastal waters and pollution due to pesticide applications,
Reduction in greenhouse gas emission
Implementing Agency: Mayem Panlot Sangha,
Sindhudurg
Advantages• Positive Yield Attributes: 60-80% higher grain yield as compared to
traditional method• Low water Requirement: Alternate drying and wetting of paddy • Reduces pressure on Land: Higher productivity (40-80%)• Low seed requirement: Seed requirement Only 8Kg/Ha. Compared
to 80 kg in traditional system• Low Inorganic Fertiliser use: Dependence on green manure and
compost reduces inorganic fertilisers• Low pesticide use: Owing to low plant density, penetration of
sunlight and aeration of the field is proper resulting in low incidences of disease and pests
• Greenhouse gas emission: Methane gas emission is less because of lack of standing water column
• Improved grain quality: More grain & less chaff• Grain ripening is quicker: Grain ripening is 7-10 days sooner• Improved Food Security: Higher productivity from small holdings• Low labour requirement: In long run labour requirement reduced • Better Drought Copping: Owing to low seed rate, staggered
nursery is feasible in the event of unfavourable monsoon
