Biofertilizer for Chilli in India (2026): Seedling Dip, Dose per Acre and Cost for the Transplanted Crop

Short answer: for one acre of transplanted chilli (about 8,000–10,000 plants), dip the seedling roots for 30 minutes in Mycorrhiza VAM Liquid at 10 ml per litre of water, then apply 2–3 litres of VAM Liquid per acre through drip or soil drench at transplanting, followed by 1 litre of NPK Consortia per acre at day 25–30 and again at day 55–60. At current Orgogrowth prices that is roughly ₹232–348 for VAM and ₹188 for two NPK Consortia doses — about ₹420–540 per acre for the whole biological programme, including GST.

Chilli has a fine, shallow root system and a long picking season, so mycorrhiza belongs on the root at transplanting, not at flowering: colonisation takes 2–3 weeks and must be finished before the plant starts heavy fruit set.

The numbers at a glance

• Seedling dip: 10 ml VAM Liquid per litre of water, 30 minutes, in shade, just before transplanting (a 100-litre dip bath uses 1 litre).
• VAM Liquid, soil/drip: 2–3 litres per acre in 200 litres of water at transplanting. Price ₹5,800 per 50-litre drum (₹116/litre incl. 5% GST), so ₹232–348 per acre.
• NPK Consortia: 1 litre per acre through drip, two doses. Price ₹4,699 per 50-litre drum (₹94/litre), so about ₹94 per dose.
• Strength: our VAM Liquid is specified at ≥200 infective propagules per ml of Glomus species, and our NPK Consortia at ≥2×10⁸ CFU/ml each of Azotobacter, Pseudomonas (PSB) and Frateuria (KMB), against FCO 1985 minimums of 100 IP/ml and 1×10⁸ CFU/ml.

Why chilli suits mycorrhiza

Chilli is a heavy feeder over a long season, with repeated flushes of flowers and green or red fruit. Like most vegetables it forms arbuscular mycorrhizal associations, and its main limit in many Indian soils is not total phosphorus but available phosphorus: much of the DAP you apply is fixed in the soil within weeks. Mycorrhizal hyphae extend the root's reach into soil the root hairs cannot access. Our liquid is specified at a 30–50% improvement in phosphorus uptake and supports up to 30% lower DAP use; treat that as a ceiling to verify on your own plot, not a guarantee.

The transplant schedule

Last week in the nursery: avoid fungicide drenches. Carbendazim and Mancozeb damage the fungus, so keep a 7–10 day gap before or after VAM.

Day 0 (transplanting): prepare the dip bath (10 ml VAM Liquid per litre), dip roots for 30 minutes in shade and transplant the same day. Do not keep leftover dip solution for the next day.

Day 0–3: apply 2–3 litres per acre of VAM Liquid in 200 litres of water as a drench along the rows or through the drip line. If you did the root dip, use the lower 2-litre rate.

Day 25–30: apply 1 litre per acre of NPK Consortia through drip in 200 litres of water, 2–3 days after the fertiliser dose rather than the same day. If your soil test supports it, cut the chemical NPK in that dose by about 25% (our NPK Consortia is specified to reduce chemical NPK 25–30%).

Day 55–60: repeat NPK Consortia at 1 litre per acre as plants enter heavy flowering and fruit set.

Cost per acre, worked out

VAM Liquid at 2 litres: 2 × ₹116 = ₹232. Two NPK Consortia doses: 2 × ₹94 = ₹188. Total about ₹420 per acre; at the 3-litre VAM rate about ₹536. Saving even one 50 kg bag of DAP per acre usually outweighs the entire biological programme, but verify it: treat one strip and keep an untreated strip beside it.

What to check after three weeks

Gently lift two or three plants from the treated strip and the control strip. Treated plants should show more white, fine feeder roots and less transplant shock. Colonisation itself needs a lab stain to confirm, so judge by root mass and early vigour.

Which product to buy

• Mycorrhiza VAM Liquid 50 L (₹5,800) — best for drip growers; one drum covers 16–25 acres at 2–3 L/acre.
• Mycorrhiza VAM Powder 1 Kg (₹2,499) — compact pack for smaller farms, 6000 IP/gm, 100 g per acre.
• NPK Consortia 50 L (₹4,699) — Azotobacter, PSB and KMB for the 25–30% chemical NPK saving.

Frequently asked questions

How much mycorrhiza does an acre of chilli need?

2–3 litres of our VAM Liquid per acre, or 100 g of VAM Powder (6000 IP/gm), applied at transplanting.

Can I use the root dip and the drip dose together?

Yes. The dip places the fungus at the root zone; the drip dose spreads it through the bed. Use the lower 2-litre rate when you dip.

Can I mix it with fungicide?

No. Keep a 7–10 day gap from Carbendazim or Mancozeb.

What does the programme cost?

Roughly ₹420–540 per acre for VAM plus two NPK Consortia doses, including GST.

Is it FCO compliant?

Yes, our products are made to FCO 1985 specifications in our ISO 9001:2015 certified unit in Mehsana, Gujarat, and dispatched within 24–48 hours.
