Why Use Catalyst Gold Tuber Boost from Agristar: The Secret to Bigger Tubers, Heavy Bulbs, and Record Harvests

Every commercial farmer growing root and tuber crops knows one simple truth: market brokers and buyers pay top shilling for size, uniform grading, and heavy weight. Whether you are farming Irish potatoes in Nyandarua, Nakuru, Meru, or Narok, or harvesting crisp red onions in Kajiado and Kirinyaga, the difference between an average season and bumper profits comes down to tuber bulking.

That is where **Catalyst Gold® Tuber Boost** from Agristar comes in. Specially formulated for tuber initiation, bulb formation, and rapid enlargement, this specialized nutrition solution gives your crops the exact bio-chemical signals and fuel they need to fill out into grade-one produce.

### The Powerhouse Formulation: What Makes Tuber Boost Unique?

Unlike standard top-dressers or generic foliar feeds, Catalyst Gold® Tuber Boost delivers a targeted concentration of high-potency nutrients:

1. **Ultra-High Phosphorus (50% P₂O₅) for Tuber Initiation:**

Phosphorus is the master energy engine of the plant (ATP). During early tuber set, it stimulates the plant to set more stolons and initiate more tubers per plant, dramatically multiplying your potential yield count.

2. **Heavy Potassium (35% K₂O) for Rapid Bulking & Starch Synthesis:**

Potassium acts as the "transporter" that pulls sugars and starches produced in the leaves directly down into the developing tubers and bulbs. This causes rapid enlargement, solid tuber density, and prevents hollow hearts.

3. **Vital Micronutrients (Zinc 5%, Calcium 2.5%, Boron 2%):**

- **Calcium (Ca):** Strengthens cell walls, giving potatoes a tough, disease-resistant skin that resists bruising during harvest and extends shelf life.

- **Boron (B):** Works hand-in-hand with calcium to ensure smooth translocation of sugars, preventing internal browning and splitting in onions and carrots.

- **Zinc (Zn):** Regulates plant growth hormones (auxins) to ensure continuous root and tuber development.

4. **Bio-Stimulants & Trace Elements (T.E):**

Helps the crop overcome environmental stress like drought or sudden heat waves, ensuring the bulking process continues without interruption.

5. **Built-In Sticking Effect:**

No need to buy a separate wetting agent. Tuber Boost is engineered with a specialized surfactant that spreads and sticks the nutrients onto the leaves, preventing rain wash-off and guaranteeing maximum leaf absorption.

### Target Crops

Catalyst Gold® Tuber Boost is proven and recommended for all tuber and bulb crops in Kenya:

- **Irish Potatoes (Viazi)** – Enhances tuber set, tuber sizing, and tough skin formation.

- **Red & White Onions** – Maximizes bulb enlargement, neck tightness, and storage dry matter.

- **Garlic** – Promotes large, firm, well-divided cloves.

- **Carrots & Beetroots** – Ensures straight, thick, crack-free roots with rich coloration.

- **Sweet Potatoes & Cassava** – Accelerates root thickening and starch accumulation.

### Recommended Application & Timing

To get the highest return on your investment, timing your sprays is key:

- **Potatoes:**

- *1st Application (Tuber Initiation):* Apply 40ml to 50ml per 20L knapsack when the crop begins hook formation / stolon swell (usually 4 to 6 weeks after planting).

- *2nd Application (Bulking Phase):* Repeat 14 days later during active tuber expansion to achieve maximum tuber weight and grading size.

- **Onions & Garlic:**

- Apply 40ml to 50ml per 20L knapsack at the onset of bulbing (typically 60 to 75 days after transplanting) and repeat 2 weeks later.

*Tip: For best results, spray early in the morning (6:00 AM – 9:30 AM) or late in the afternoon when leaf stomata are open.*
