Nepal Krishi Fertilizer Guide: Urea, DAP & Potash Dosage Per Ropani & Bigha
Balanced fertilization based on soil science recommendations from the Nepal Agricultural Research Council (NARC) maximizes agricultural crop yields while preserving long-term soil health. Computing exact chemical fertilizer ratios of Nitrogen (Urea), Phosphorus (DAP), and Potassium (MOP / Potash) per Ropani or Bigha prevents nutrient waste.
- DAP supplies both Phosphorus (46%) and initial Nitrogen (18%) during early basal root establishment.
- Urea supplies primary Nitrogen (46%) and should be applied in split top-dressings across crop vegetative stages.
- Muriate of Potash (MOP) supplies Potassium (60%), improving grain filling and drought resistance.
- Chemical fertilizer applications should be balanced with at least 500 kg to 1,000 kg of well-rotted organic compost per Ropani.
NARC Recommended Fertilizer Slabs for Paddy (Rice) per Ropani
Standard fertilizer guidelines for high-yielding irrigated paddy in the hilly valleys:
| Fertilizer Type | Basal Application at Sowing | First Top Dressing (3 Weeks) | Second Top Dressing (Panicle Stage) |
|---|---|---|---|
| DAP (18:46:0) | 5.5 kg (Full Dose at planting) | None | None |
| MOP / Potash (0:0:60) | 3.5 kg (Full Dose at planting) | None | None |
| Urea (46:0:0) | 2.0 kg (Basal Starter) | 4.0 kg (Tillering stage) | 4.0 kg (Panicle initiation) |
| Organic Compost / Gobar Mal | 1,000 kg (During field ploughing) | None | None |
Converting Dosage from Ropani to Bigha Systems
One Bigha equals approximately 13.31 Ropani. When calculating commercial agricultural input budgets for Terai plots, multiply the standard per-Ropani kilogram requirement by 13.31 to determine bulk 50-kg sack procurement needs.
