Basmati rice Fertilizer Calculator
Work out the exact urea, DAP and MOP for basmati rice from the recommended 90:45:30 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P, K at transplanting; remaining N in two splits at tillering and panicle initiation. Restraint is the strategy — excess N lodges the tall crop and dulls aroma.
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 Basmati rice Fertilizer Calculator to convert the official basmati rice 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 Basmati rice Fertilizer Calculator
Basmati is deliberately under-fertilized relative to coarse rice: tall aromatic types lodge under heavy N, and exporters dock for chalky over-fed grain, so the schedule trades a little yield for quality and standability. This calculator starts from the published recommendation of 90:45:30 kg/ha N-P₂O₅-K₂O (evolved basmati (pb-1121/1509)) or 60:30:30 kg/ha N-P₂O₅-K₂O (traditional tall basmati), 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 Basmati rice Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (evolved basmati (pb-1121/1509) / traditional tall basmati) 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 Basmati rice Fertilizer Calculator?
- ✓Official package-of-practices dose for basmati rice — 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 basmati rice?+
Evolved Basmati (PB-1121/1509): 90 kg N, 45 kg P₂O₅ and 30 kg K₂O per hectare; Traditional tall Basmati: 60 kg N, 30 kg P₂O₅ and 30 kg K₂O per hectare. Half N + full P, K at transplanting; remaining N in two splits at tillering and panicle initiation.
Why is basmati given less nitrogen than ordinary paddy?+
Tall basmati lodges badly above ~60 kg N/ha, and even semi-dwarf evolved types lose aroma, elongation and export grade when over-fed. The 90:45:30 cap is a quality decision.
When should the last urea go on basmati?+
At panicle initiation. Later N raises grain chalkiness and pushes maturity into cooler weather, hurting both milling recovery and the export sample.
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.
