Max Size Certified Organic Fertilizer (5L): The Fruit Expander & Yield Booster
Maximize your harvest weight, size, and sweetness with 60% Fish Protein Power.
YK Laboratories "Max Size" (5L) is a professional-grade organic biostimulant designed for commercial farmers. Packed with 60% Fish Crude Proteins and 35% Fish Amino Acids, it acts as a "muscle builder" for your crops. It specifically targets the fruit-setting stage to rapidly expand cell size (hypertrophy), ensuring your Tomatoes, Melons, and Papayas reach their maximum marketable size without using synthetic hormones.
Best For: Commercial Horticulture (Tomato, Chilli, Capsicum, Fruits) looking for Export Quality produce and higher tonnage.
Why Choose This Product? Key Benefits
- ?Increases Fruit Size & Weight:
Contains natural Auxins and Amino Acids that trigger rapid cell expansion, preventing small or deformed fruits. - ?Boosts Sweetness & Color:
Improves the mobilization of sugars to the fruit (Brix level), resulting in shiny, attractive, and sweeter produce. - ?️Prevents Fruit Drop:
Strengthens the fruit stalk (pedicel), reducing the drop of young fruits during heat stress or wind. - ⏳Export Quality (0 Residue):
NPOP Certified Organic. You can spray it right up to the harvest day (0-day PHI) with no fear of chemical residue rejection. - ?Commercial Economy:
The 5L pack offers massive savings (approx. 30% cheaper per liter) compared to buying small bottles, lowering your cost per acre.

How It Works: Mode of Action
Max Size utilizes "Marine Bio-Technology" to trick the plant into focusing all its energy on fruit development.
- Cell Expansion (Hypertrophy): The natural Auxins and Amino Acids signal the fruit cells to stretch and hold more water. This physically increases the volume of the fruit without making it "puffy" or hollow.
- Source-Sink Mobilization: It acts like a traffic controller, directing sugars produced in the leaves (Source) to move rapidly into the fruit (Sink). This increases the weight and solid content of the harvest.
- Energy Sparing: Plants usually waste energy converting soil nitrogen into proteins. Max Size provides ready-made amino acids, saving the plant energy which it then uses to grow bigger fruits.
Result: Uniform, heavy, and shiny fruits with extended shelf life.
Target Crops & Benefits
| Crop | Key Results |
|---|---|
| Tomato & Chilli | Increases fruit caliber (size), reduces flower drop, and ensures uniform ripening. |
| Melons (Watermelon/Musk) | Significantly boosts sugar content (Brix) and internal flesh density. |
| Papaya & Banana | Promotes elongation (length) and prevents fruit deformity ("bumpy" fruits). |
| Leafy Vegetables | Increases leaf width and chlorophyll content for a lush green appearance. |
Dosage & Application Guide
The Golden Rule: Timing is everything. Start applying AFTER the fruit has set (pea size) for maximum expansion.
Dosage per Acre & Application Method
| Method | Dose (Standard) | Commercial Dose | Frequency | PHI (Days) |
|---|---|---|---|---|
| Foliar Spray (Best) | 2 ml / Litre | 400 ml / Acre (200L Water) | Every 15 Days | 0 Days |
| Drip Irrigation | - | 2 - 3 Liters / Acre | Monthly | 0 Days |
| Fruit Dip (Grapes) | 1 ml / Litre | - | Once at berry setting | 0 Days |
*PHI = Pre-Harvest Interval: You can harvest immediately after spraying.
How to Apply: Best Practices
- Timing: Spray in the late afternoon or evening. The protein content absorbs better in cooler temperatures and won't burn leaves under the hot sun.
- Don't Spray Flowers: Avoid heavy spraying during peak pollination (flowering) to prevent washing away pollen. Wait until the small fruits appear.
- Tank Mixing: Compatible with most organic pesticides (like Neem or Beauveria). Do NOT mix with heavy copper fungicides or strong chemical herbicides.
- Storage: Store the 5L can in a cool, dark place. Fish proteins are sensitive to heat and sunlight.
Frequently Asked Questions
1. How is the 5L pack better than the 1L bottle?
The 5L pack is designed for commercial farmers. It costs roughly ₹400 per Litre compared to ₹600+ for small bottles, saving you nearly 30% on input costs.
2. Is this a chemical PGR?
No. Max Size is 100% Organic and NPOP certified. It uses natural fish amino acids and auxins to stimulate growth, making it safe for export crops with zero residue.
3. Can I use it on Hydroponic plants?
Yes. Since it is a liquid protein hydrolysate, it dissolves easily in water and is excellent for hydroponic systems to boost root and fruit mass.
4. Will it make the fruit hollow or puffy?
No. Unlike synthetic chemicals that force expansion with air/water, Max Size fills the fruit cells with proteins and sugars, ensuring the fruit remains dense and heavy.
5. What is the shelf life?
Approximately 3 years if stored correctly. Keep the cap tightly closed and away from direct sunlight to prevent the organic proteins from spoiling.
