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 23 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Segbana is close to normal, so these dates match the pattern the area usually follows.
Planting after 11 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Segbana
| 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 964 mm |
| This season's rain | Rain close to usual — plan around about 964 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 | 2 kinds of ground. The season below is the largest that farms — about 69% of this area. |
| 69% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 174 growing days · about 1,000 mm · May to October |
|---|---|
| 29% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 181 growing days · about 1,040 mm · April to October |

What it takes to grow common bean in Segbana
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 82 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 28 kg per hectare |
| Potash (K₂O) | About 42 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 81–185 days per hectare, by hand |
These are the nutrients a common bean 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.
