Guinea-Bissau
Pearl millet (Pennisetum glaucum) is the toughest grain you can grow.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 11 May 2026 – 18 Sep 2026 closed for this season | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.5 t/ha | about 3.5 t/ha |
| Harvest | From 10 Jul 2026 to 16 Jan 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 75–150 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 21 May 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Bolama/Bijagos 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 18 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Bolama/Bijagos
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For pearl millet in Bolama/Bijagos, the lie of the land is the tightest of the three at 88%. 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 Bolama/Bijagos
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2026 to November 2026 |
| Rain in a typical year | About 2,014 mm in a typical farming district |
| Across its districts | From about 1,853 mm in the driest of 4 districts to about 2,169 mm in the wettest |
| This season's rain | Leaning dry — September and October 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. |
| This season's heat | Hotter than usual — about +0.7 °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 | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 55% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 2,160 mm · May to November |

What pearl millet needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.0 |
| Spacing | 60 cm between rows, 12 cm between plants |

What it takes to grow pearl millet in Bolama/Bijagos
| Planting material | About 180,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare |
| Phosphate (P₂O₅) | About 54 kg per hectare |
| Potash (K₂O) | About 98 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 | 75–150 days per hectare, by hand |
These are the nutrients a pearl millet 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.
