Jasmine Water Requirement Calculator
Work out the seasonal and per-irrigation water requirement of jasmine (mogra) (FAO-56 ETc = ET₀ × Kc, peak Kc 0.9) for your field, climate, soil and irrigation method.
Keep moisture even through the flowering season for continuous buds; drip suits the bush crop. A short stress after pruning helps synchronise the flush, then steady water sustains daily picking.
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 Jasmine Water Requirement Calculator
Jasmine needs 700–1000 mm a year of steady moisture, with peak demand during the long summer flowering flush. This calculator uses the FAO-56 method — crop evapotranspiration ETc = ET₀ × Kc — with jasmine (mogra)'s own crop coefficients (Kc 0.5 initial, 0.9 mid-season, 0.75 late) across a 330-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 Jasmine 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 Jasmine Water Requirement Calculator?
- ✓Uses jasmine (mogra)'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 jasmine (mogra) need?+
Jasmine needs 700–1000 mm a year of steady moisture, with peak demand during the long summer flowering flush. The exact figure depends on climate and season length; this tool sums ET₀ × Kc across the crop's 330-day growth stages for your conditions.
How much water does jasmine need?+
About 700–1000 mm a year for field jasmine, peaking in the summer flowering flush. Steady drip moisture sustains the daily bud harvest through the season.
How does irrigation affect jasmine flowering?+
A brief stress after pruning helps trigger a synchronised flush; thereafter steady, even moisture maximises continuous bud production. Drought drops buds and shortens the picking season.
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.
