When to plant Taro in Isna
Qena, Egypt
Cocoyam, or taro (Colocasia esculenta), is a broad-leaved plant grown for its corm — a heavy, potato-like food store that swells underground — and, in some types, for its tender young leaves.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 Jan 2026 – 1 Jan 2027 open now |
| Expected harvest | about 21.1 t/ha |
| Bearing cycle | 180–540 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. |
| Work it takes | 111–233 days per hectare, by hand |
Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Isna is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow taro in Isna
| Planting material | About 24,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 95 kg per hectare |
| Phosphate (P₂O₅) | About 47 kg per hectare |
| Potash (K₂O) | About 158 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 111–233 days per hectare, by hand |
These are the nutrients a taro crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
