Chrysanthemum Water Requirement Calculator
Work out the seasonal and per-irrigation water requirement of chrysanthemum (guldaudi) (FAO-56 ETc = ET₀ × Kc, peak Kc 1) for your field, climate, soil and irrigation method.
Keep moisture steady through budding and flowering for full blooms; drip with mulch keeps flowers clean. The short-day crop's bloom timing is set by daylength, but water stress then shrinks flowers.
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 Chrysanthemum Water Requirement Calculator to turn the FAO-56 crop coefficients for chrysanthemum (guldaudi) into a real seasonal water volume and an irrigation interval for their own field — no agronomy tables, works offline.
About Chrysanthemum Water Requirement Calculator
Chrysanthemum needs 450–600 mm of even moisture, with peak demand during bud formation and flowering. This calculator uses the FAO-56 method — crop evapotranspiration ETc = ET₀ × Kc — with chrysanthemum (guldaudi)'s own crop coefficients (Kc 0.5 initial, 1 mid-season, 0.85 late) across a 125-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 Chrysanthemum 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 Chrysanthemum Water Requirement Calculator?
- ✓Uses chrysanthemum (guldaudi)'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 chrysanthemum (guldaudi) need?+
Chrysanthemum needs 450–600 mm of even moisture, with peak demand during bud formation and flowering. The exact figure depends on climate and season length; this tool sums ET₀ × Kc across the crop's 125-day growth stages for your conditions.
How much water does chrysanthemum need?+
About 450–600 mm over the season, peaking at bud formation and flowering. Even drip moisture through this stage gives full-sized, high-quality blooms.
Why are my chrysanthemum blooms small?+
Moisture or nutrient stress during budding shrinks flowers. While flowering is triggered by short days, steady irrigation through bud development determines bloom size and quality.
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.
