| When to plant | 16 Sep 2026 – 6 Oct 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 1.4–1.6 t/ha | about 3.0 t/ha |
| Harvest | From 30 Nov 2026 to 3 Feb 2027, depending on the planting date | |
| Ready to harvest | 75–120 days after planting | |
| Work it takes | 81–185 days per hectare, by hand | |
| Rain meets its needs | 69% | |
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 Mandera 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 6 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mandera
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For common bean in Mandera, the lie of the land is the tightest of the three at 76%. 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.

| Across its districts | From about 258 mm in the driest of 6 districts to about 322 mm in the wettest |

What common bean needs to grow here
| Soil it likes | well-drained sandy loam, loam, silt loam or clay loam soil |

| Spacing | 50 cm between rows, 10 cm between plants |

What it takes to grow common bean in Mandera
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 53 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 27 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.
