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 16 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Gogounou is close to normal, so these dates match the pattern the area usually follows.
Planting after 25 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Gogounou
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For fonio in Gogounou, 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 2027 season in Gogounou
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2027 to October 2027 |
| Rain in a typical year | About 975 mm |
| This season's rain | Rain close to usual — plan around about 975 mm falling roughly when it always does |
| 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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 56% of this area. |
| 56% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 177 growing days · about 980 mm · May to October |
|---|---|
| 37% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 181 growing days · about 1,010 mm · April to October |
| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 182 growing days · about 1,010 mm · April to October |

What fonio needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 6.5 |

What it takes to grow fonio in Gogounou
| Nitrogen (N) | About 30 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 30 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 | 82–175 days per hectare, by hand |
These are the nutrients a fonio 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.
