Coriander Fertilizer Calculator
Work out the exact urea, DAP and MOP for coriander (seed) from the recommended 60:30:30 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P, K basal; rest N at first irrigation (~30–35 days). For leafy harvests, shift N earlier and cut at 30–35 days; seed crops need the later N for umbel fill.
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 Coriander Fertilizer Calculator to convert the official coriander (seed) 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 Coriander Fertilizer Calculator
Seed coriander and leafy dhaniya are fed differently from the same plan: leaf crops front-load nitrogen and finish in a month, while seed crops save the second N split for umbel filling. This calculator starts from the published recommendation of 60:30:30 kg/ha N-P₂O₅-K₂O (irrigated) or 30:15:15 kg/ha N-P₂O₅-K₂O (rainfed), 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 Coriander Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (irrigated / rainfed) 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 Coriander Fertilizer Calculator?
- ✓Official package-of-practices dose for coriander (seed) — 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 coriander (seed)?+
Irrigated: 60 kg N, 30 kg P₂O₅ and 30 kg K₂O per hectare; Rainfed: 30 kg N, 15 kg P₂O₅ and 15 kg K₂O per hectare. Half N + full P, K basal; rest N at first irrigation (~30–35 days).
Is the fertilizer plan different for leafy vs seed coriander?+
Same total, different timing. Leaf crops take N early and are cut by 35 days; seed crops hold the second N split until branching/umbel initiation for seed fill.
Why did my coriander bolt early with poor leaf yield?+
Heat plus moisture stress, not fertilizer, drives early bolting — but lush early N under stress makes it worse. Sow timely, irrigate lightly and often for leaf crops.
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.
