Cucumber Fertilizer Calculator
Work out the exact urea, DAP and MOP for cucumber 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 in the planting basins/beds; rest N in two splits at vining and first-fruit set. Pick every 1–2 days — overgrown fruit left on the vine shuts down new setting.
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 Cucumber Fertilizer Calculator to convert the official cucumber 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 Cucumber Fertilizer Calculator
Cucumber sets fruit continuously only if it's both fed and picked relentlessly; the split N keeps vines extending while harvest discipline keeps the sink demand alive. This calculator starts from the published recommendation of 100:50:50 kg/ha N-P₂O₅-K₂O (open field), 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 Cucumber 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 Cucumber Fertilizer Calculator?
- ✓Official package-of-practices dose for cucumber — 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 cucumber?+
Open field: 100 kg N, 50 kg P₂O₅ and 50 kg K₂O per hectare. Half N + full P, K in the planting basins/beds; rest N in two splits at vining and first-fruit set.
Why did my cucumber vines stop producing mid-season?+
Usually missed pickings (mature fruit suppresses new set) plus N exhaustion. Pick on a 1–2 day cycle and give the second N split at peak fruiting to extend the season.
What causes bitter cucumbers?+
Stress — heat, drought, irregular feeding — raises cucurbitacins. Even moisture and steady moderate fertility are the prevention; bitterness is not caused by fertilizer type.
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.
