When to plant Common bean in Kenya
Known here as maharage · maharagwe
The common bean is the number-one grain legume that people in East and Southern Africa eat straight from the pot — as dry beans (a pulse) or as fresh green/snap pods.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 13 Mar 2027 – 10 Jul 2027 opens in 23 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.3 t/ha | about 2.8 t/ha |
| Harvest | From 27 May 2027 to 7 Nov 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-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 30 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Kenya 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 10 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kenya
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For common bean in Kenya, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026 season in Kenya
| When the rains are expected | January 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,566 mm in a typical farming district |
| Across its districts | From about 210 mm in the driest of 290 districts to about 2,002 mm in the wettest |
| Rainy seasons, district by district | Of 290 districts: one rainy season in 67 and two rainy seasons in 75 |
| 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 +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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 8 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 48% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 300 mm · October to December |
|---|---|
| 12% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 126 growing days · about 520 mm · October to January |
| 9% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 209 growing days · about 750 mm · September to January |
| 7% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 166 growing days · about 590 mm · October to January |
| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 356 growing days · about 1,240 mm · December to December |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 286 growing days · about 900 mm · March to December |
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 241 growing days · about 760 mm · October to June |
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 237 growing days · about 770 mm · March to December |

What common bean needs to grow here
| Soil it likes | well-drained sandy loam, loam, silt loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 50 cm between rows, 10 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow common bean in Kenya
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 76 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 39 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.
