What grows in Riyom
Plateau, Nigeria
The 2026 season in Riyom
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | April 2026 to November 2026 |
| Rain in a typical year | About 1,316 mm |
| This season's rain | Leaning wet — October 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 +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 full main crop, 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 95% of this area. |
| 95% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 227 growing days · about 1,280 mm · April to November |
|---|---|
| 5% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 225 growing days · about 1,190 mm · April to November |

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.
What grows in Riyom with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it
The crops and dates above are read at cells spread across Riyom, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Riyom?
Cashew, Cucumber, Jute mallow, African eggplant, African nightshade all rate well in Riyom — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Cashew in Riyom?
In Riyom the window for Cashew runs 8 Apr 2026 to 20 Sep 2026.
Is there a farming app that works in Riyom?
Divisi does. It reads Riyom's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Riyom, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
