Fig Water Requirement Calculator
Work out the seasonal and per-irrigation water requirement of fig (anjeer) (FAO-56 ETc = ET₀ × Kc, peak Kc 0.85) for your field, climate, soil and irrigation method.
Steady moisture through fruit growth, then ease water as fruit ripens to raise sweetness and prevent splitting. Drip suits the crop; the deep roots tolerate moderate stress.
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 irrigation planners use the free Fig Water Requirement Calculator to turn the FAO-56 crop coefficients for fig (anjeer) into a real seasonal water volume and an irrigation interval for their own field — no agronomy tables, works offline.
About Fig Water Requirement Calculator
Fig needs 600–800 mm, and a controlled drier finish concentrates the sugars that make quality fruit. This calculator uses the FAO-56 method — crop evapotranspiration ETc = ET₀ × Kc — with fig (anjeer)'s own crop coefficients (Kc 0.4 initial, 0.85 mid-season, 0.6 late) across a 220-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 Fig 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 Fig Water Requirement Calculator?
- ✓Uses fig (anjeer)'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 fig (anjeer) need?+
Fig needs 600–800 mm, and a controlled drier finish concentrates the sugars that make quality fruit. The exact figure depends on climate and season length; this tool sums ET₀ × Kc across the crop's 220-day growth stages for your conditions.
How much water does fig need?+
About 600–800 mm over the season, peaking at fruit growth. A controlled drier finish during ripening concentrates sugars and limits fruit splitting.
Why ease water as figs ripen?+
Excess water at ripening dilutes sweetness and splits the soft fruit; a controlled finish raises Brix and quality, much like in grapes and melons.
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.
