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 6 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Tigania East leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 26 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Tigania East
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | September 2026 to January 2027 |
| Rain in a typical year | About 978 mm |
| This season's rain | Leaning wet — January, February, October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +0.9 °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 | 4 kinds of ground. The season below is the largest that farms — about 38% of this area. |
| 38% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 205 growing days · about 890 mm · September to January |
|---|---|
| 22% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 161 growing days · about 610 mm · October to January |
| 14% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 253 growing days · about 1,440 mm · September to June |
| 8% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 123 growing days · about 500 mm · October to December |

What it takes to grow common bean in Tigania East
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 79 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 26 kg per hectare |
| Potash (K₂O) | About 41 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.
