When to plant Turmeric in Hai
Kilimanjaro, United Republic of Tanzania
Known here as manjano · binzari manjano
Turmeric is a leafy, ginger-like plant grown for the bright orange, aromatic rhizome (underground stem) hidden beneath it — the source of the yellow spice, the dye, and its own next-season seed.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 29 Sep 2026 – 18 Nov 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 16.9 t/ha | about 30.0 t/ha |
| Harvest | From 27 Apr 2027 to 14 Sep 2027, depending on the planting date | |
| Ready to harvest | 210–300 days after planting | |
| Work it takes | 159–282 days per hectare, by hand | |
| Rain meets its needs | 77% | |
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 29 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Hai leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 18 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Hai
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For turmeric in Hai, the lie of the land is the tightest of the three at 60%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The 2026 season in Hai
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 622 mm |
| This season's rain | Leaning wet — February look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.1 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |
| What that supports | enough rain for one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 34% of this area. |
| 34% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 134 growing days · about 610 mm · February to June |
|---|---|
| 17% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 189 growing days · about 760 mm · February to July |
| 9% | enough rain for a long crop, or two in a year; cold for much of the year, with a short planting season 315 growing days · about 1,480 mm · September to July |
| 8% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 306 growing days · about 1,350 mm · September to July |

Limited water holds back about 25% of yield here.
What turmeric needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 50 cm between rows, 25 cm between plants |
| Feed it most with | potassium and nitrogen |
What it takes to grow turmeric in Hai
| Nitrogen (N) | About 59 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 101 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 | 159–282 days per hectare, by hand |
These are the nutrients a turmeric 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.
