When to plant Soybean in Tarkwa Nsuaem
Western, Ghana
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 | 10 Feb 2027 – 29 Aug 2027 opens in 19 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.7 t/ha | about 3.6 t/ha |
| Harvest | From 11 May 2027 to 26 Jan 2028, depending on the planting date | |

| 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 2 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Tarkwa Nsuaem 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 29 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For soybean in Tarkwa Nsuaem, the lie of the land is the tightest of the three at 60%. 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.

| When the rains are expected | January 2025 to January 2025 |

| This season's rain | Leaning dry. Plant at the early end of the window and favour quicker, more drought-tolerant crops. |

What it takes to grow soybean in Tarkwa Nsuaem
| Planting material | About 350,000 plants per hectare |

| Nitrogen (N) | About 148 kg per hectare |
