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 21 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Githunguri 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 13 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For common bean in Githunguri, 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.

What it takes to grow common bean in Githunguri
| Planting material | About 175,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 73 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 37 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.
