Safflower Fertilizer Calculator
Work out the exact urea, DAP and MOP for safflower from the recommended 60:40:20 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Rainfed: full dose drilled deep at sowing into moisture. Irrigated: half N + full P, K basal, rest N at first irrigation (~35 days). The deep taproot does the late-season foraging.
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 Safflower Fertilizer Calculator to convert the official safflower 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 Safflower Fertilizer Calculator
Safflower follows the rabi-jowar playbook — drilled deep into residual vertisol moisture — but its spiny canopy and taproot let it finish on a modest dose where wheat would fail. This calculator starts from the published recommendation of 60:40:20 kg/ha N-P₂O₅-K₂O (irrigated) or 40:25:0 kg/ha N-P₂O₅-K₂O (rainfed (residual moisture)), 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 Safflower Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (irrigated / rainfed (residual moisture)) 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 Safflower Fertilizer Calculator?
- ✓Official package-of-practices dose for safflower — 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 safflower?+
Irrigated: 60 kg N, 40 kg P₂O₅ and 20 kg K₂O per hectare; Rainfed (residual moisture): 40 kg N, 25 kg P₂O₅ and 0 kg K₂O per hectare. Rainfed: full dose drilled deep at sowing into moisture.
How is safflower fertilized on residual moisture?+
Drill the full 40:25:0 with the seed into the moist zone at sowing — there is usually no usable rain later, so splits don't work in classic rainfed safflower.
Does safflower need potash on black soils?+
Usually no — Deccan vertisols supply ample K. Apply 20 kg K2O only under irrigation or 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.
