Comprehensive guide to growing 'Chodi' - the mineral-rich power grain of South India.

Ragi Grains

Introduction

Popular Varieties

  • Tirumala (PPR 1012), Saptagiri (PPR 2614), Indravathi (CFMV-1), VR series (VR 520/687/580), PPR 2700, Gosthani (VR 1099), Padmawathi, Maruti, and biofortified lines.
  • Choose ANGRAU/ICAR‑IIMR recommended releases for blast resistance, drought tolerance and nutrition.

Step 1: Soil Preparation

Ragi prefers light red loam, sandy loam or porous upland soils with good drainage; pH 4.5–8.0. It tolerates low fertility but avoids waterlogging.

Detailed Process:

  1. Field Clearance: Remove all weeds, stubble, and previous crop residues from the field.
  2. Summer Ploughing: Perform one deep plough (20–30 cm) during April–May to conserve moisture and kill soil-borne pests.
  3. Harrowing: Conduct 2–3 harrowings or discings to create a fine, smooth seedbed required for small ragi seeds.
  4. Land Graded: Ensure the field is well-leveled to prevent water stagnation.
  5. Organic Amendment: Incorporate 5–10 t/ha of FYM, compost, or green manure during the final tillage.
  6. Drainage Prep: In high-rainfall areas, form raised beds or ridges to facilitate water runoff.
  7. Basal Feeding: Apply basal nutrients (40–60 kg N and 20–40 kg P2O5/ha) according to your latest soil test report.

Step 2: Sourcing Seeds

Choosing blast-resistant varieties is the most effective way to ensure a stable ragi yield.

Detailed Process:

  1. Variety Selection: Choose high-yielding, blast-resistant types like Tirumala (PPR 1012) or Saptagiri.
  2. Verify Source: Buy only from APSSDC, ANGRAU, or NSC-recognized seed dealers.
  3. Check Certification: Look for the official tag confirming 80%+ germination and varietal purity.
  4. Secure Quantity: Get 4–5 kg/ha for line sowing or 2–3 kg/ha for the SFMI/Guli method.
  5. Pre-Sowing Treatment: Treat seeds with fungicides (Thiram) and bio-agents (Azospirillum) to boost establishment.

Step 3: Transplanting / Sowing

Whether direct sowing or transplanting, the depth and spacing determine the final plant population and tillering.

Detailed Process:

  1. Nursery Management: For transplanting, raise seedlings in beds; ensure they are healthy before moving.
  2. Seedling Age: Transplant at 18–21 days (or younger if using the SFMI method).
  3. Sowing/Transplant Timing: Align with the Kharif monsoon (June–July) for best results.
  4. Configuration: Maintain a spacing of 25–30 cm between rows and 10–15 cm between plants.
  5. Sowing Depth: If direct sowing, place seeds at a shallow depth of 3–4 cm.
  6. Initial Care: Irrigate lightly immediately after transplanting to settle the roots and ensure success.

Step 4: Harvesting

Harvesting ragi in multiple pickings can sometimes be more effective, but single-stage harvest is common for large fields.

Detailed Process:

  1. Maturity Identification: Harvest when most fingers turn brown and grains become hard and stone-like.
  2. Moisture Check: Aim for grain moisture between 15–20% during harvest.
  3. Harvesting Method: Cut the ear-heads (panicles) manually or use a reaper; store stalks for fodder.
  4. Initial Drying: Sun-dry the harvested ear-heads for 3–4 days on a clean floor.
  5. Threshing: Use a mechanical thresher or beat with sticks to separate the tiny grains.
  6. Final Conditioning: Dry the grains further until the moisture level is 12–14%.
  7. Storage: Store in air-tight bins or pest-proof bags; ragi has an excellent shelf-life if kept dry.

Follow ANGRAU/ICAR‑IIMR recommendations: use blast‑resistant varieties, IPM (scouting, neem/bio‑pesticides), weed control (hoeing/pre‑emergent), split N and SFMI/Guli practices where promoted. Contact local KVK/DAATTC for demos and latest varietal advice.

Pro Tip: Maturity Sign

Harvest when the grain turns yellowish-brown and the moisture content is around 15-20%. Over-drying in the field can lead to grain shattering.
