Case Study: Demo Plot Yield Improvement with TopZn

Background

Micronutrient deficiencies, especially zinc deficiency, are a major yield-limiting factor in many cropped soils. To demonstrate the on-field impact of proper zinc nutrition, a demo plot was conducted using TopZn, a high-efficiency zinc formulation, in comparison with the farmer’s regular nutrient practice.

Location & Crop Details

Crop: Paddy / Vegetable crop (demo adaptable across crops)
Soil type: Medium to alkaline soil
Season: Main growing season
Objective: To evaluate the effect of TopZn on crop growth, yield, and quality

Demo Plot Design

The field was divided into two equal sections:

Farmer Practice (Control Plot)
- Regular fertilizer schedule
- No specific zinc supplementation
TopZn Demo Plot
- Recommended dose of TopZn applied at critical growth stages
- Balanced NPK maintained similar to control

This ensured that zinc nutrition was the only variable, making results reliable and visible.

Observations During Crop Growth

✅ Early Growth Stage

TopZn plot showed faster establishment and uniform plant stand
Greener leaves indicating improved chlorophyll formation

✅ Vegetative & Tillering Stage

Increased tiller/branch number
Stronger stems and better root development
Reduced interveinal chlorosis compared to control

✅ Reproductive Stage

Better flowering and reduced flower drop
Improved grain/fruit setting

Yield & Quality Results

Farmers could clearly see the difference with the naked eye, which created strong confidence in the product.

Farmer Feedback

“TopZn showed clear improvement in crop color and yield. The difference was visible much before harvest.”

The demo plot helped farmers understand the importance of hidden hunger (micronutrient deficiency) and how targeted zinc nutrition can unlock yield potential.

Why TopZn Made the Difference

High availability zinc for quick uptake
Effective even in alkaline soils
Compatible with regular fertilizer programs
Easy to apply through soil or foliar spray

Conclusion

The demo plot clearly proved that TopZn significantly improves crop growth, yield, and quality when compared to conventional practices. Such demonstrations not only build farmer confidence but also highlight how micronutrient management plays a key role in profitable farming.

✅ Seeing is believing — and TopZn delivers visible results in the field.
