When to plant Soybean in Buyo
Nawa, Côte d'Ivoire
Known here as soja
Soybean (Glycine max) is a bushy, knee-high bean grown for a seed that is rich in protein and oil — good to eat, good to sell, and it leaves the soil richer for whatever you plant next.

| Fit | Favourable | |
| When to plant | 22 Feb 2027 – 6 Sep 2027 opens in 21 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.8 t/ha | about 3.7 t/ha |
| Harvest | From 23 May 2027 to 3 Feb 2028, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 68–141 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 8 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Buyo leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 6 Sep 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Buyo
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For soybean in Buyo, 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 Buyo
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,380 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 71% of this area. |
| 71% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 327 growing days · about 1,400 mm · February to December |
|---|---|
| 27% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 291 growing days · about 1,360 mm · February to November |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 326 growing days · about 1,460 mm · February to December |

Frost and pest pressure hold back about 15% of yield here.
What soybean needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Rain it needs | About 600–1,500 mm across the season |
| Spacing | 50 cm between rows, 6 cm between plants |
| Feed it most with | phosphorus, potassium and sulphur |
What it takes to grow soybean in Buyo
| Planting material | About 350,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 154 kg per hectare |
| Phosphate (P₂O₅) | About 42 kg per hectare |
| Potash (K₂O) | About 56 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 68–141 days per hectare, by hand |
These are the nutrients a soybean 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.
