A balanced Fertilizer Plan for Rice Crop is essential for boosting yields, improving grain quality, and ensuring sustainable farming in Pakistan. Rice (Chawal) is not only a staple food for millions but also a top export commodity, with varieties like Basmati from Punjab and IRRI from Sindh earning significant foreign exchange.
Unfortunately, fertilizer use in Pakistan often lacks scientific planning. Some farmers apply excessive nitrogen, leading to lodging, while others underapply phosphorus and potassium, resulting in weak plants and poor grain filling. By adopting a scientific, stage-wise fertilizer plan, farmers can increase yields by 15–25% while reducing costs.
In this guide, we will detail a practical fertilizer plan suited to Pakistan’s climatic conditions, soil types, and farming practices.
Understanding Rice Crop Nutrient Requirements in Pakistan
Rice is a nutrient-demanding crop requiring macronutrients and micronutrients in balanced proportions.
Key Macronutrients:
Nitrogen (N): Vital for vegetative growth and tiller development.
Phosphorus (P₂O₅): Encourages strong roots and early establishment.
Potassium (K₂O): Strengthens stems, boosts disease resistance, and enhances grain filling.
Important Micronutrients:
Zinc (Zn): Essential for enzyme activation and protein synthesis.
Sulphur (S): Supports chlorophyll formation.
Boron (B): Improves grain quality and reduces sterility.

Best Soil Preparation Practices for Rice Crop
The Role of Soil Testing
Before implementing any Fertilizer Plan for Rice Crop, conduct soil testing from a government-approved lab.
Benefits of Soil Testing:
Identifies nutrient deficiencies.
Prevents overuse of expensive fertilizers.
Helps design a field-specific plan.
For example, Sheikhupura soils often lack zinc, while Larkana fields are low in potassium. Without testing, farmers risk applying unnecessary nutrients, wasting money.

Recommended Fertilizer Doses for Rice in Pakistan
The Pakistan Agricultural Research Council (PARC) recommends the following per-acre doses for optimum yield:
| Nutrient | Quantity per Acre | Common Fertilizer Source |
|---|---|---|
| Nitrogen | 80–100 kg N | Urea (46% N) |
| Phosphorus | 40–60 kg P₂O₅ | DAP (18:46:0), SSP (16% P₂O₅) |
| Potassium | 40–50 kg K₂O | MOP (60% K₂O) |
| Zinc | 10–12 kg ZnSO₄ | Zinc Sulphate (21% Zn) |
| Sulphur | 10–15 kg S | Gypsum, SOP |
Stage Wise Fertilizer Application Plan
Basal Dose (Before Transplanting)
Apply half of the Nitrogen + full Phosphorus + full Potassium.
Example per acre:
DAP: 2–3 bags (100–150 kg)
MOP: 1 bag (50 kg)
Zinc Sulphate: 10–12 kg
Farmer Tip: In heavy clay soils of Gujranwala, mix zinc sulphate with moist soil for uniform application.
Tillering Stage (20–25 Days After Transplanting)
Apply ¼ of the remaining Nitrogen using Urea.
Maintain 2–3 inches of standing water to improve nitrogen uptake.
c. Panicle Initiation Stage (40–45 Days After Transplanting)
Apply the final ¼ of Nitrogen.
Foliar spray 1% Potassium Nitrate to improve grain setting.
Integrating Organic Matter
Most Pakistani soils have <1% organic matter, which limits nutrient availability. Applying Farmyard Manure (FYM) or compost improves:
Soil structure
Nutrient retention
Microbial activity
Recommendation: Apply 8–10 tonnes FYM per acre 3–4 weeks before transplanting.
Zinc Management for Pakistani Rice Fields
Zinc deficiency is widespread in rice belts, particularly in Punjab’s central districts.
Symptoms: Yellowing of young leaves, stunted plants, poor tillering.
Management:
Apply 10–12 kg zinc sulphate during land preparation.
For severe cases, foliar spray 0.5% zinc sulphate solution.

Efficient Water and Fertilizer Use
With Pakistan’s increasing water scarcity, Alternate Wetting and Drying (AWD) is gaining popularity.
Guidelines:
Maintain moist soil, avoid prolonged flooding.
Apply fertilizers when soil is damp, not waterlogged.
Avoid urea application before heavy rain.
Fertilizer Application Methods
Broadcasting: Widely used but prone to nutrient loss.
Band Placement: Places fertilizer near roots, improving efficiency.
Foliar Feeding: Effective for micronutrients like zinc and boron.
Common Fertilizer Mistakes to Avoid
Applying all nitrogen at once → causes lodging.
Ignoring micronutrients → lowers grain quality.
Over-reliance on urea without P & K → nutrient imbalance.
Not matching fertilizer to soil type → wasted investment.
Variety Wise Fertilizer Requirement
This is based on PARC and provincial agriculture department recommendations, keeping local soil and yield potential in mind.
| Rice Variety | Nitrogen (N) | Phosphorus (P₂O₅) | Potassium (K₂O) | Zinc (ZnSO₄) | Notes |
|---|---|---|---|---|---|
| IRRI (Long Grain Non-Basmati) | 100–110 kg N (≈2.25 bags Urea) | 60–65 kg P₂O₅ (≈1.5 bags DAP) | 50–55 kg K₂O (≈1 bag MOP) | 10–12 kg Zinc Sulphate | Suited for Sindh’s coastal & delta areas; split N into 3 doses. |
| Basmati (Aromatic) | 80–90 kg N (≈2 bags Urea) | 40–50 kg P₂O₅ (≈1–1.25 bags DAP) | 40–45 kg K₂O (≈0.8 bag MOP) | 8–10 kg Zinc Sulphate | Apply N in 3 splits; avoid excessive N to prevent lodging & quality loss. |
| Hybrid (High Yield) | 120–130 kg N (≈2.75–3 bags Urea) | 60–70 kg P₂O₅ (≈1.5–1.75 bags DAP) | 55–60 kg K₂O (≈1–1.1 bags MOP) | 12–15 kg Zinc Sulphate | Needs higher N & K for maximum yield; ensure adequate irrigation. |
Cost-Benefit Analysis for Farmers
An optimized Fertilizer Plan for Rice Crop can boost income significantly.
Example (per acre):
Without plan → 60 maunds yield (~PKR 180,000 at PKR 3,000/maund)
With plan → 80 maunds yield (~PKR 240,000)
Profit difference: PKR 60,000 extra per acre
Environmental Considerations
Excess fertilizer use not only wastes money but also harms the environment. Nitrate leaching contaminates groundwater, and overuse of urea contributes to greenhouse gas emissions. Sustainable fertilizer use benefits both farmers and the environment.
Conclusion
A well-structured Fertilizer Plan for Rice Crop designed for Pakistan’s conditions ensures higher yields, better grain quality, and improved farmer income. Start with soil testing, follow stage-wise nutrient application, integrate organic matter, and don’t neglect micronutrients like zinc. By combining modern science with traditional farming knowledge, Pakistani farmers can secure their livelihoods and contribute to national food security.
