Organic Rice (Paddy) Cultivation: Complete Stage-by-Stage Protocol
Full organic paddy protocol from nursery to harvest — SRI method, Azolla integration, Beejamrutham treatment, and disease management for India's most important crop.
Organic Rice (Paddy) Cultivation
Basics
Varieties: Desi (Kalanamak, Navara, Bao-Dhan), improved (Pusa varieties), or SRI-suited varieties Soil: Loam to clay, pH 5.5–7.0 Season: Kharif (June–November in most regions)
Stage-by-Stage Organic Protocol
| Stage | Action |
|---|---|
| Land Prep | Apply 5–7 t/ha FYM or compost, 3 weeks before transplanting |
| Seed Treatment | Beejamrutham, 24-hour soak |
| Nursery | Jeevamrutham drench (500 L/ha) at 7 days after sowing |
| Transplanting | SRI method: 8–12 day old seedlings, 1 plant/hill, 25×25 cm spacing |
| Basal | Azospirillum + PSB (2 kg each/ha) mixed with compost |
| Tillering | Jeevamrutham + Panchagavya foliar at 30 days after sowing |
| Panicle Initiation | Panchagavya + Seaweed extract foliar spray |
| Blast Control | Pseudomonas + Trichoderma soil drench (preventive) |
| Brown Planthopper | Neemastra spray |
SRI (System of Rice Intensification)
SRI is a water and seed-efficient transplanting method that often increases organic rice yield by 25–50% compared to conventional flooded paddy transplanting:
- Young seedlings (8–12 days, not 25–30 days)
- Single seedling per hill (not 3–4 bunched)
- Wide spacing (25×25 cm)
- Intermittent wetting and drying (not continuous flooding)
- Mechanical weeder used between rows (also aerates soil)
This method reduces water use by 30–40% while increasing yield — a rare win-win for organic paddy farmers.
Azolla Integration
Azolla is a water fern with a symbiotic nitrogen-fixing cyanobacterium (Anabaena azollae) living in its leaf cavities — a free, self-propagating biofertilizer for paddy fields.
- Fixes 20–40 kg N/ha when grown as a companion in paddy water
- Also suppresses weed growth by covering water surface
- Establishment: simply scatter fresh Azolla onto flooded paddy field — it multiplies rapidly
- Can be incorporated into soil before next transplanting for additional N release
Key Disease and Pest Notes
- Blast disease: Preventive Trichoderma + Pseudomonas soil drench is far more effective than reactive treatment
- Brown planthopper: Avoid excess nitrogen (even organic) — promotes lush growth that attracts planthoppers; Neemastra controls active infestation
- Stem borer: Trichogramma egg parasitoid release weekly during egg-laying period
