Nichino Pravardhak Biofertilizer (VAM Technology)
Unlock the full potential of your soil with the power of Mycorrhiza.
Nichino Pravardhak is a premium Granular Biofertilizer powered by Vesicular Arbuscular Mycorrhiza (VAM). Unlike standard chemical fertilizers, Pravardhak is a biological input that creates a symbiotic network with your crop's roots. It acts as an extension of the root system, helping plants access deep-soil nutrients and water that are otherwise unreachable.
Perfect for: Increasing root mass, improving soil health, and boosting nutrient uptake (especially Phosphorus and Zinc) in both rainfed and irrigated crops.
Why Choose Pravardhak? Key Benefits
-
⏱️
Maximizes Nutrient Uptake: Solubilizes fixed Phosphorus and actively transports Zinc and Copper to the plant, boosting growth efficiency.
-
🛡️
Enhanced Root Network: Increases the effective root surface area by 10x to 100x, creating a stronger anchor and better feeding system.
-
⏳
Long-Term Soil Health: Produces "Glomalin," a natural glue that improves soil structure, aeration, and porosity for future crops.
-
🌧️
Drought Proofing: Penetrates micro-pores in the soil to access trapped moisture, keeping crops green during dry spells.
-
🌿
Transplant Shock Reduction: Ensures higher survival rates for seedlings and saplings by establishing immediate root connections.

How It Works: Mode of Action
Pravardhak works on a biological "Infection and Expansion" principle:
- Symbiotic Attachment: Upon application, VAM spores germinate and penetrate the plant roots, forming a friendly "infection" or bond.
- Network Expansion: The fungus grows fine threads (hyphae) that extend far beyond the root zone, bypassing the "Nutrient Depletion Zone."
- Active Transport: These hyphae act like biological pipes, absorbing moisture and immobile nutrients (P, Zn) and delivering them directly into the root cells.
This creates a highly efficient "second root system" that works 24/7 for the plant.
Target Crops & Pests
| Crop System | Key Benefits |
|---|---|
| Cereals (Paddy, Wheat, Maize) | Improves tillering, grain filling, and root anchorage in aerobic/SRI conditions. |
| Commercial (Cotton, Sugarcane) | Enhances drought survival in rainfed areas; boosts taproot depth. |
| Horticulture (Vegetables, Fruits) | Reduces transplant shock and prevents micronutrient deficiencies (like Zinc). |
Dosage & Application Guide
The Golden Rule: Always follow the "Basal Dose Method" (at sowing time) for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop Type | Dose (kg / Acre) | Application Mode | Dose (per Plant) | PHI (Days) |
|---|---|---|---|---|
| Short Duration (Paddy, Veg, Pulses) | 4 kg | Soil Broadcast | - | 0 |
| Long Duration (Cotton, Sugarcane) | 8 kg | Soil Broadcast | - | 0 |
| Fruit Orchards (Mango, Citrus) | - | Ring Method | 50g - 100g | 0 |
*PHI = Pre-Harvest Interval: 0 Days because Pravardhak is a biological product and leaves no toxic residue.
How to Apply: Best Practices
- Timing: Apply as a Basal Dose (at the time of sowing or planting). The spores need time to colonize young roots. Late application is less effective.
- Mixing: Mix the granular product with 50-100 kg of well-decomposed Farm Yard Manure (FYM), compost, or field soil for uniform distribution.
- Coverage: Broadcast uniformly in the field. Ensure the granules are incorporated into the top 3-6 inches of soil (root zone). Surface application without mixing is not recommended (UV light kills spores).
- Safety: Always wear PPE (gloves, mask) to prevent inhaling dust. Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Pravardhak in drip irrigation?
No. Pravardhak is a granular formulation with a clay/carrier base that can clog drip emitters. For drip systems, look for liquid VAM. Use Pravardhak for soil broadcasting only.
2. Is it compatible with chemical fertilizers like Urea or DAP?
Yes, it is generally compatible. You can mix it with NPK fertilizers for broadcasting. However, apply immediately after mixing; do not leave the mixture sitting for long periods.
3. Can I use fungicides with this product?
Avoid applying soil-drench fungicides (like Carbendazim) 7-10 days before or after applying Pravardhak, as they can kill the beneficial VAM fungus. Foliar sprays are generally safe.
4. What is the shelf life of the product?
Biologicals are sensitive. The standard shelf life is usually 6-12 months. Ensure you store the packet in a cool, dry place away from direct sunlight to keep the spores alive.
5. Why is it recommended for drought-prone areas?
The VAM hyphae (fungal threads) are much thinner than plant roots. They can enter tiny soil pores to extract water that roots cannot reach, keeping the plant hydrated longer during dry spells.
