Pomegranate Water Requirement Calculator
Work out the seasonal and per-irrigation water requirement of pomegranate (FAO-56 ETc = ET₀ × Kc, peak Kc 0.85) for your field, climate, soil and irrigation method.
Keep soil moisture even through fruit development — moisture swings after a dry spell crack the fruit. Drip is standard; a controlled stress before bahar induces flowering. Calcium and boron with even water complete the anti-crack package.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Pomegranate Water Requirement Calculator
Drip-irrigated pomegranate needs 600–900 mm a year, and even moisture during fruit development is the key to preventing the cracking that wrecks export grade. This calculator uses the FAO-56 method — crop evapotranspiration ETc = ET₀ × Kc — with pomegranate's own crop coefficients (Kc 0.5 initial, 0.85 mid-season, 0.65 late) across a 230-day season. Pick your climate band (which sets reference ET₀), irrigation method (drip, sprinkler, pivot or surface — each with its own efficiency) and soil texture, and it returns the seasonal water need in cubic metres, the peak daily demand, the net depth per irrigation and how many days to wait between irrigations.
How to use Pomegranate Water Requirement Calculator
- 1Enter your field area and choose the climate band matching your season.
- 2Select your irrigation method and soil texture.
- 3Read the seasonal water volume, peak daily demand and irrigation interval, then follow the scheduling note.
Why use Pomegranate Water Requirement Calculator?
- ✓Uses pomegranate's real FAO-56 Kc curve, not a flat factor
- ✓Accounts for drip / sprinkler / pivot / surface efficiency
- ✓Gives seasonal volume, peak daily need and an irrigation interval
- ✓Free, instant and fully in-browser — works offline in the field
Frequently asked questions
How much water does pomegranate need?+
Drip-irrigated pomegranate needs 600–900 mm a year, and even moisture during fruit development is the key to preventing the cracking that wrecks export grade. The exact figure depends on climate and season length; this tool sums ET₀ × Kc across the crop's 230-day growth stages for your conditions.
How do I prevent pomegranate fruit cracking with irrigation?+
Keep soil moisture even and avoid sudden heavy irrigation (or rain) after dry spells during fruit growth. Drip irrigation, mulch, and adequate calcium/boron together prevent most cracking.
How much water does pomegranate need?+
About 600–900 mm a year via drip, varying with the bahar taken. Demand peaks during fruit development; the deep roots and induced-stress flowering keep total use moderate for a fruit crop.
What is ET₀ and Kc?+
ET₀ (reference evapotranspiration) is how fast a standard grass surface loses water in your climate. Kc (crop coefficient) scales it to a specific crop and growth stage. Crop water use ETc = ET₀ × Kc — the basis of FAO-56 irrigation scheduling.
Is this calculator free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
