This article explains fertilizer dose, field preparation, GA3 application, water management, seed production, crop nutrition, and professional hybrid rice cultivation practices.
🌱 Basal Dose – Boro Seed Bed (Hybrid Seed Production & Trial)
| Fertilizer | Recommended Dose (kg/ha) |
|---|---|
| TSP | 140 |
| MOP | 120 |
| Gypsum | 100 |
| ZnSO₄ | 10 |
| Furadan | 15 |
| Urea | 70 |
This fertilizer schedule is recommended for preparing healthy Boro seed beds for hybrid rice seed production and research trials.
🌾 Basal Dose – Boro Main Field (All Trial)
| Fertilizer | Dose (kg/ha) |
|---|---|
| TSP | 140 |
| MOP | 120 (2/3 Basal + 1/3 Top Dress) |
| Gypsum | 70 |
| ZnSO₄ | 10 |
| Urea | 50 |
This dose is suitable for all Boro rice research trials and demonstration plots.
🌾 Basal Dose – Hybrid Rice Seed Production
| Fertilizer | Dose (kg/ha) |
|---|---|
| TSP | 200 |
| MOP | 160 (2/3 Basal + 1/3 Top Dress) |
| Gypsum | 100 |
| ZnSO₄ | 10 |
| Urea | 50 |
Higher phosphorus and potassium application improves panicle development and hybrid seed quality.

| MOP | 100 (1/3 Top Dress) |
| Gypsum | 70 |
| ZnSO₄ | 10 |
| Urea | 130 (Apply in 3 Splits) |
🌾 Aman Inbred Rice Seed Production
| Fertilizer | Dose (kg/ha) |
|---|---|
| TSP | 80 |
| MOP | 80 (1/3 Top Dress) |
| Gypsum | 60 |
| ZnSO₄ | 8 |
| Urea | Apply According to Field Condition |
🌿 Field Management Tips
🌱 Soil Preparation
Prepare well-levelled land with proper drainage before transplanting.
💧 Irrigation
Maintain shallow water during early growth stage and avoid water stress.
🌾 Fertilizer
Use balanced NPK along with Zinc and Gypsum for better seed quality.
🦠 Pest Management
Inspect the field weekly and control insects and diseases immediately.
⚠ Important Note
Always adjust nitrogen fertilizer according to crop condition, soil fertility and weather. Excess nitrogen increases lodging and disease incidence.
