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 Apr 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Koinadugu is close to normal, so these dates match the pattern the area usually follows.
Planting after 26 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

For common bean in Koinadugu, 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 season in Koinadugu
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to December 2026 |
| Rain in a typical year | About 2,275 mm |
| This season's rain | Rain close to usual — plan around about 2,275 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.8 °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 a long crop, or two in a year, 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 55% of this area. |
| 55% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 287 growing days · about 2,310 mm · March to December |

What it takes to grow common bean in Koinadugu
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 46 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 24 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.
