Best Biofertilizer for Chickpea (Chana) in India 2026: Dosage per Acre, Price & Rabi Schedule That Cuts DAP Cost

Quick answer: The best biofertilizer schedule for chickpea (chana / gram) in India is a two-step Rabi programme — Mycorrhiza VAM at 100 g per acre at sowing plus NPK+VAM Consortia at 3–4 litres per acre through drip or soil drench at 25–30 days after sowing. Cost on the Orgogrowth schedule works out to roughly ₹540–640 per acre for the season (VAM powder ₹250/acre from a ₹2,499 1 Kg pack that covers ~10 acres, plus ₹294–392/acre from a ₹4,699 50 L NPK+VAM drum that covers 12–16 acres). Chickpea is a phosphorus-hungry pulse, and mycorrhiza is the single most cost-effective way to unlock the "fixed" phosphorus already sitting in Indian black and alluvial soils — typically cutting DAP/SSP need by 40–60%.

"For chana, put mycorrhiza in at sowing and consortia at 25–30 days — that one change cuts your DAP bill by roughly half and gives you more pods per plant." — Orgogrowth India field team, Gujarat, Rabi 2025–26.

Why chickpea responds so well to biofertilizer

Chickpea is India's largest pulse crop — grown on roughly 100 lakh hectares across Madhya Pradesh, Maharashtra, Rajasthan, Gujarat, Karnataka and Uttar Pradesh, mostly on residual moisture after the kharif harvest. Three things make it an ideal crop for a biological nutrition programme:

• It is a legume. Chickpea forms root nodules with Rhizobium and fixes much of its own nitrogen, so the nutrient that actually limits yield is phosphorus, followed by sulphur and zinc.
• Phosphorus gets locked up fast. In calcareous soils of Gujarat and Rajasthan and the black cotton soils of MP and Maharashtra, up to 70–80% of applied DAP is fixed within weeks as calcium or iron/aluminium phosphates. Mycorrhizal hyphae reach that fixed pool — a plant root cannot.
• It is grown on stored moisture. The mycorrhizal hyphal network extends the effective root zone many times over, which is why VAM-treated chana visibly tolerates the terminal drought of February–March better than untreated plots.

The Orgogrowth chickpea schedule (per acre)

If you already use a Rhizobium seed treatment, keep it — the products above are compatible and Rhizobium + PSB + mycorrhiza is the combination recommended by ICAR-IIPR for pulses. Just keep a 7–10 day gap from any seed-dressing fungicide or soil-applied chemical fungicide.

What to reduce on the chemical side

The standard recommendation for chana is roughly 8 kg N + 16 kg P₂O₅ per acre (about 35 kg DAP). With the schedule above, Orgogrowth customers typically drop to 15–20 kg DAP per acre with no loss of nodulation or pod set — a saving of ₹500–700 per acre on DAP alone at 2026 prices, which more than pays for the biofertilizer. Keep sulphur (gypsum or bentonite sulphur) and a zinc source in the programme; mycorrhiza also improves zinc uptake, but does not replace it in zinc-deficient fields.

Field results we track

Across our Rabi 2025–26 customer plots in North Gujarat (Mehsana, Patan and Banaskantha), chana fields on the VAM + NPK+VAM schedule averaged 12–18% more pods per plant than the farmers' own DAP-only control strips, with the biggest gains in fields that had gone 2+ seasons without organic manure. These are farmer-reported comparisons, not replicated trials, so treat the range as indicative — but it lines up with published ICAR work showing 10–20% grain-yield gains from mycorrhizal inoculation in pulses.

Frequently asked questions

What is the biofertilizer dose for chickpea per acre?

100 g of Mycorrhiza VAM powder (6000 IP/g) at sowing, then 3–4 litres of NPK+VAM Consortia at 25–30 days after sowing, each in about 200 litres of water through drip or drench.

How much does biofertilizer for chana cost per acre?

About ₹540–640 per acre for the full season on the Orgogrowth schedule — ₹250 for VAM powder and ₹294–392 for NPK+VAM Consortia.

Can I use mycorrhiza with Rhizobium seed treatment?

Yes. Rhizobium, PSB and mycorrhiza are complementary and are commonly recommended together for pulses. Avoid mixing biofertilizer with chemical fungicide in the same tank.

Does mycorrhiza replace DAP in chickpea?

Not fully. It lets you cut DAP by roughly 40–60% by unlocking phosphorus already fixed in the soil. Apply a reduced basal dose of 15–20 kg DAP per acre rather than dropping it entirely, especially in fields with a low soil-test P value.

When should I sow chana and apply the biofertilizer?

Optimum sowing is mid-October to mid-November across central and western India (up to end-November in the south). Apply VAM at sowing or with the first irrigation, and the consortia at branching around day 25–30.

Is it safe for rainfed chana?

Yes — rainfed fields benefit most, because the mycorrhizal network improves water uptake from deeper soil. Apply VAM with the sowing moisture and the consortia with the first light irrigation or after a winter shower.
