When to plant Soybean in Longido
Arusha, United Republic of Tanzania
Known here as soya
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.

| When to plant | 9 Oct 2026 – 27 Jan 2027 opens in 1 week | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.0 t/ha | about 4.0 t/ha |
| Harvest | From 7 Jan 2027 to 26 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |

| Rain meets its needs | 67% | |
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 18 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Longido 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 27 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Longido
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2026 to May 2026 |
| Rain in a typical year | About 556 mm |
| This season's rain | Leaning wet — January, February, 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 one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 31% of this area. |
| 31% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 159 growing days · about 520 mm · February to May |
|---|---|
| 21% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 135 growing days · about 430 mm · February to May |
| 20% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 370 mm |
| 13% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 215 growing days · about 640 mm · October to June |

What it takes to grow soybean in Longido
| Planting material | About 350,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 110 kg per hectare |
| Phosphate (P₂O₅) | About 30 kg per hectare |
| Potash (K₂O) | About 40 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.
