When to plant Turmeric in Nyanza-Lac
Makamba, Burundi
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.

| When to plant | 16 Sep 2026 – 5 Nov 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 21.8 t/ha | about 26.3 t/ha |
| Harvest | From 14 Apr 2027 to 1 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-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 6 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Nyanza-Lac 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 5 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Nyanza-Lac
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For turmeric in Nyanza-Lac, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Nyanza-Lac
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 1,015 mm |
| This season's rain | Leaning wet — January, October, November and December 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 +1.0 °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 full main crop, 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 52% of this area. |
| 52% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 263 growing days · about 1,030 mm · October to June |
|---|---|
| 27% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 276 growing days · about 1,150 mm · September to June |
| 9% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 278 growing days · about 1,230 mm · September to June |
| 6% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 273 growing days · about 1,180 mm · September to June |

Frost and pest pressure hold back about 15% 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 Nyanza-Lac
| Nitrogen (N) | About 76 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 17 kg per hectare |
| Potash (K₂O) | About 131 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.
