FASAL ZINC (Zinc Sulphate 33%)

Zinc Sulphate 33% is a high-analysis micronutrient fertilizer formulated to correct zinc (Zn) deficiency and support balanced crop nutrition. Zinc plays an important role in enzyme activation, chlorophyll formation, protein synthesis, growth regulation, and reproductive development. Zinc deficiency can lead to stunted growth, poor tillering, chlorosis, reduced flowering and fruit set, and lower yield.

Why Farmers Should Use Zinc Sulphate 33%

Zinc is required in small quantities, but its role in plant metabolism is significant. A crop may receive adequate nitrogen, phosphorus and potassium yet still perform poorly when an essential micronutrient such as zinc is deficient.

Zinc Sulphate 33% is therefore particularly useful when soil testing or crop symptoms indicate zinc deficiency. It helps complete the crop's nutrient requirement and supports more efficient, balanced crop development. ICAR research also highlights zinc's role in enzyme activation, auxin synthesis, chlorophyll formation, and protein and nucleic-acid metabolism.

Recommended Dosage

Soil Application:
10 kg per acre

Apply uniformly to the soil and incorporate appropriately. The exact requirement can vary according to crop, soil type, existing zinc status, and local recommendations. Soil-test-based fertilizer management is preferred, especially for repeated applications.

Note: Zinc fertilizer should be used as part of a balanced nutrient-management programme and not as a substitute for NPK or other essential nutrients.

Zinc Sulphate 33% helps to:

• Correct zinc deficiency in soil and crops
• Promote strong and healthy root development
• Support chlorophyll formation and greener foliage
• Improve vegetative growth and tillering
• Support flowering and fruit setting
• Improve grain filling and reproductive development
• Enhance nutrient utilization and overall plant vigour
• Support better crop quality and yield potential
• Maintain balanced micronutrient nutrition
• Improve crop performance where zinc deficiency is limiting growth

Before Using Zinc Sulphate – Typical Zinc Deficiency Symptoms

When crops are zinc deficient, farmers may observe:

• Pale or yellowing young leaves
• Interveinal chlorosis
• Brown or dusty spots on leaves
• Shortened internodes and stunted plants
• Reduced tillering
• Poor vegetative growth
• Weak flowering and reproductive development
• Poor grain formation or reduced yield potential

For example, TNAU identifies chlorosis, brown spots, stunted growth and low tillering among zinc-deficiency symptoms in rice.

Before Application

Zinc-deficient crop → Pale leaves → Poor growth → Weak tillering/branching → Reduced flowering or fruit set → Lower yield potential

After Using Zinc Sulphate – Expected Crop Response

When zinc deficiency is corrected, the crop can regain healthier nutrient balance and growth. Depending on the crop, soil condition, severity of deficiency and timing of application, farmers may observe:

• Greener, healthier foliage
• Improved plant vigour
• Better root development
• Improved tillering and branching
• Stronger vegetative growth
• Better flowering and fruit setting
• Improved grain filling
• Better crop quality
• Higher yield potential when zinc deficiency was a limiting factor

ICAR field research in rice has demonstrated substantial yield improvement from adding zinc to balanced fertilizer programmes where zinc was a limiting nutrient.

After Application

Zinc deficiency corrected → Healthier green foliage → Stronger growth → Better flowering/fruit set → Improved grain/fruit development → Better yield potential
