Cumin Fertilizer Calculator
Work out the exact urea, DAP and MOP for cumin (jeera) from the recommended 30:15:0 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P basal; remaining N with the first irrigation (~30 days). Light, infrequent feeding on light soils — heavy N plus humidity is a blight invitation in jeera.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Farmers and agronomists use the free Cumin Fertilizer Calculator to convert the official cumin (jeera) recommendation into exact urea, DAP and MOP quantities for their own field in seconds — no agronomy tables, no spreadsheet, and it works offline in the field.
About Cumin Fertilizer Calculator
Cumin on Rajasthan–Gujarat sands is farmed defensively: a deliberately lean 30:15:0 schedule, because lush over-fed canopies are the classic trigger for devastating blight and wilt. This calculator starts from the published recommendation of 30:15:0 kg/ha N-P₂O₅-K₂O (irrigated light soils), adjusts it ±25% for your soil-test N, P and K ratings, scales it to your field area in hectares, acres or bigha, and converts the nutrients into real products — urea (46% N), DAP (18-46-0) and MOP (0-0-60) — including the number of bags to buy.
How to use Cumin Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition and your soil-test ratings for N, P and K — leave Medium if you have no recent soil test.
- 3Read off the urea, DAP and MOP quantities and bag counts, then follow the split-application note for timing.
Why use Cumin Fertilizer Calculator?
- ✓Official package-of-practices dose for cumin (jeera) — not a generic NPK guess
- ✓Soil-test Low/Medium/High ratings adjust the dose ±25% automatically
- ✓Converts nutrients to urea, DAP and MOP bags, with the DAP nitrogen credit handled correctly
- ✓Works in hectares, acres and bigha — and runs fully in your browser, even offline in the field
Frequently asked questions
What is the recommended fertilizer dose for cumin (jeera)?+
Irrigated light soils: 30 kg N, 15 kg P₂O₅ and 0 kg K₂O per hectare. Half N + full P basal; remaining N with the first irrigation (~30 days).
Why is the cumin fertilizer dose kept so low?+
Dense, nitrogen-lush cumin canopies stay humid and invite Alternaria blight — the disease that destroys jeera crops. The lean 30:15:0 plan trades a little growth for a lot of disease safety.
Does cumin need potash?+
On the light alkaline soils of the jeera belt, soil K is usually adequate and packages omit it; apply 10–15 kg K2O only where a soil test reads low.
How does the calculator convert NPK into urea, DAP and MOP?+
DAP (46% P₂O₅) is sized to cover the phosphorus need; the nitrogen it also carries (18% N) is credited against the N requirement, and urea (46% N) supplies the balance. MOP (60% K₂O) covers potassium. Bag counts use 45 kg urea and 50 kg DAP/MOP bags.
Is this tool free, and does my data leave the device?+
It is completely free with no sign-up, and all calculation happens in your browser — nothing you enter is uploaded, so it also works offline in the field.
