Guava Fertilizer Calculator
Per-tree guava fertilizer planner — age-based doses up to 600:300:600 g N-P₂O₅-K₂O per tree/year converted into urea, DAP and MOP for your whole orchard.
Two splits aligned to the crop you want: for the prized winter (mrig bahar) crop, feed in June–July after withholding water — the stress-then-feed cycle is the bahar treatment itself.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Orchardists use the free Guava Fertilizer Calculator to turn the per-tree recommendation into total urea, DAP and MOP for the whole block — young and bearing trees included — without a single hand calculation.
About Guava Fertilizer Calculator
Guava fertilization doubles as crop scheduling: the bahar treatment — a deliberate stress followed by feeding and irrigation — steers the tree into the profitable winter crop instead of the insipid rainy-season one. The calculator uses the age-laddered recommendation — 150:75:150 g N-P₂O₅-K₂O per tree/year (1–3 years); 400:200:400 g N-P₂O₅-K₂O per tree/year (4–6 years); 600:300:600 g N-P₂O₅-K₂O per tree/year (bearing (7+)) — multiplies it across your tree count, and converts the totals into urea (46% N), DAP (18-46-0) and MOP (0-0-60) quantities for the season.

Frequently asked questions
How much fertilizer does a guava tree need per year?+
1–3 years: 150 g N, 75 g P₂O₅ and 150 g K₂O per tree per year; 4–6 years: 400 g N, 200 g P₂O₅ and 400 g K₂O per tree per year; Bearing (7+): 600 g N, 300 g P₂O₅ and 600 g K₂O per tree per year. Two splits aligned to the crop you want: for the prized winter (mrig bahar) crop, feed in June–July after withholding water — the stress-then-feed cycle is the bahar treatment itself..
What is bahar treatment in guava and where does fertilizer fit?+
Water is withheld in summer to force rest, then the full fertilizer dose plus irrigation in June–July triggers synchronized flowering for the high-quality winter crop.
Why skip or thin the rainy-season guava crop?+
Monsoon fruit is watery, insipid and fly-infested. Directing nutrition to the winter crop through bahar scheduling raises both price and quality from the same tree.
How do I convert the per-tree dose into urea, DAP and MOP?+
The tool multiplies the per-tree grams across your count, then sizes DAP to cover P₂O₅ (crediting its 18% N), urea for the remaining N, and MOP for K₂O — the same arithmetic an agronomist would do by hand.
Is this calculator free and private?+
Yes — free, no sign-up, and everything runs in your browser, so your orchard data never leaves the device and the tool works offline.
