Introduction
- Bajra (Pennisetum glaucum) is a warm-season, short-duration millet suited to arid and semi-arid zones.
- In Andhra Pradesh it is mainly Kharif rainfed (June–July sowing; Oct–Nov harvest) with pockets of irrigated/summer cultivation.
- Major districts: Anantapur, Kurnool, Nandyal, Prakasam, Y.S.R (Kadapa), and some areas in Guntur/Bapatla.
- Often intercropped (e.g., bajra + groundnut/sunflower/pigeonpea) to improve income and soil health.
- Choose downy mildew‑resistant, early‑maturing or dual‑purpose varieties for rainfed conditions.
Popular Varieties / Hybrids
- Ananta (APS‑1), ICMV 221, ICTP 8203 (WCC‑75), Pusa Composite‑612, GK‑1004, PAC‑903, Nandi‑35/360, GHB‑558, MLHB‑504, Proagro series, 86M hybrids, and SiA series or recent biofortified lines.
- Hybrids typically outperform local varieties by 20–50%; select downy mildew‑resistant types for rainfed areas.
Step 1: Soil Preparation
Bajra tolerates low‑fertility soils but prefers light sandy loam, loamy sand, or red/chalka soils with good drainage; pH 6.0–8.5.
Detailed Process:
- Field Sanitation: Clear all weeds, stubble, and debris from the previous crop cycle.
- Ploughing: Conduct 2–3 rounds of ploughing, including one deep plough (20–25 cm) to facilitate root penetration.
- Tilth Achievement: Use a harrow to ensure a fine tilth, which is essential for small seeds like bajra.
- Moisture Management: In rainfed zones, prepare ridges and furrows or broad beds to manage heavy rain runoff.
- Organic Fertilization: Apply 5–8 t/ha of FYM or compost during the last ploughing phase.
- Seedbed Levelling: Level the field to ensure uniform moisture distribution and sowing depth.
- Nutrient Application: Apply basal fertilizers (roughly 40–60 kg N and 20–40 kg P2O5/ha) as per soil test results.
Step 2: Sourcing Seeds
Quality seeds resistant to downy mildew are critical for a successful bajra crop.
Detailed Process:
- Variety Selection: Choose downy mildew-resistant hybrids (e.g., GHB-558, 86M series) or varieties (e.g., Ananta).
- Source Verification: Purchase from APSSDC, ANGRAU centers, or recognized private suppliers like Pioneer or Kaveri.
- Label Check: Verify the seed tag for at least 80% germination and physical purity.
- Measure Quantity: Ensure you have 4–5 kg/ha for line sowing or 3–4 kg/ha for hybrids.
- Seed Protection: treat seeds with fungicides (Thiram) and insecticides to protect against soil pests and shoot fly.
Step 3: Sowing / Transplanting
Sowing depth and timing with the monsoon are the most critical factors for stand establishment.
Detailed Process:
- Optimal Timing: Sow with the onset of the monsoon (late June to mid-July).
- Sowing Technique: Use a seed drill for uniform row placement.
- Depth Precision: Sow seeds at a depth of 2.5–5 cm (avoid deeper sowing in heavy soils).
- Spacing Standard: Maintain 45–60 cm between rows and 10–15 cm between plants.
- Population Control: Place 2–3 seeds per hill and thin to 1 healthy plant after 10–15 days.
- Germination Care: If a dry spell follows sowing, provide a light 'life-saving' irrigation if possible.
Step 4: Harvesting
Prompt harvesting and thorough drying prevent grain shattering and maintain quality.
Detailed Process:
- Maturity Indicators: Harvest when grains are hard, panicles turn straw-colored, and glumes are dry.
- Cut Moister Level: Aim for 15–20% grain moisture at the time of harvesting.
- Collection Method: Cut panicles manually or use a combine; cut stalks low if fodder is required.
- Initial Curing: Spread harvested panicles in the sun for 3–4 days.
- Threshing: Use a mechanical thresher or manual beating to separate grains.
- Grain Drying: Dry the grains until the moisture level reaches 12–14%.
- Safe Storage: Store in cool, dry, pest-proof gunny bags to prevent weevil infestation.
Follow ANGRAU/ICAR‑IIMR recommendations: use IPM for downy mildew and shoot fly (resistant varieties, scouting, neem), weed control (hoeing or pre‑emergent herbicides), split N application, and intercropping to improve resilience.

Pro Tip: Intercropping
Intercropping Bajra with pulses like pigeon pea or green gram improves soil fertility through nitrogen fixation and provides a diversified income for farmers.
