Okra Fertilizer Calculator
Work out the exact urea, DAP and MOP for okra from the recommended 100:50:50 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P, K basal at sowing; remaining N in two splits at 25 and 45 days. Begin picking at the right stage — over-mature pods pull nutrients away from new flowers.
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 Okra Fertilizer Calculator to convert the official okra 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 Okra Fertilizer Calculator
Okra is picked every 2–3 days for weeks, so it rewards a steady nutrient supply; the summer crop carries a higher dose than kharif because irrigation removes the moisture cap on yield. This calculator starts from the published recommendation of 100:50:50 kg/ha N-P₂O₅-K₂O (summer (irrigated)) or 80:40:40 kg/ha N-P₂O₅-K₂O (kharif), 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 Okra Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (summer (irrigated) / kharif) 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 Okra Fertilizer Calculator?
- ✓Official package-of-practices dose for okra — 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 okra?+
Summer (irrigated): 100 kg N, 50 kg P₂O₅ and 50 kg K₂O per hectare; Kharif: 80 kg N, 40 kg P₂O₅ and 40 kg K₂O per hectare. Half N + full P, K basal at sowing; remaining N in two splits at 25 and 45 days.
Why does the summer okra crop need more fertilizer than kharif?+
Summer okra under assured irrigation has a higher yield potential and a longer picking window, so the dose steps up to about 100:50:50 kg/ha versus 80:40:40 for the rain-fed kharif crop.
Does okra need micronutrients?+
Yellow-vein-mosaic-tolerant hybrids respond to balanced NPK first; on sandy or high-pH soils a basal 25 kg/ha zinc sulphate every 2–3 seasons prevents the pale, stunted growth typical of zinc deficiency.
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.
