When to plant Tobacco in Sao Tome and Principe
Tobacco is a tall, broad-leaved plant in the same family as tomato and potato, grown not for food but for its leaves, which are dried and cured, then sold by weight and grade.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 30 Jun 2026 – 22 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.1 t/ha | same |
| Harvest | From 28 Sep 2026 to 20 Jul 2027, depending on the planting date | |
| Ready to harvest | 90–120 days after planting | |
| Work it takes | 120–242 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 Sao Tome and Principe leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sao Tome and Principe
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For tobacco in Sao Tome and Principe, the lie of the land is the tightest of the three at 45%. 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 2026/27 season in Sao Tome and Principe
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,877 mm in a typical farming district |
| Across its districts | From about 1,692 mm in the driest of 7 districts to about 2,625 mm in the wettest |
| This season's rain | Leaning dry — January, February, September, October, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| What that supports | enough rain for a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 68% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,800 mm · January to December |
|---|---|
| 32% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,580 mm · January to December |

What tobacco needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 120 cm between rows, 55 cm between plants |
| Feed it most with | nitrogen and potassium |
What it takes to grow tobacco in Sao Tome and Principe
| Planting material | About 16,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 78 kg per hectare |
| Phosphate (P₂O₅) | About 23 kg per hectare |
| Potash (K₂O) | About 126 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 | 120–242 days per hectare, by hand |
These are the nutrients a tobacco 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.
