Ghana
The Irish potato (mbatatisi, ikirayi, viazi mviringo) is a cool-weather crop grown for the tubers that swell underground — it is not a grain, and it is not the same plant as sweet potato.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 7 Jul 2027 – 16 Jul 2027 opens in 40 weeks | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | about 15.4 t/ha | same |
| Harvest | From 15 Sep 2027 to 23 Nov 2027, depending on the planting date | |
| Ready to harvest | 70–130 days after planting | |
| Work it takes | 110–185 days per hectare, by hand | |
| Rain meets its needs | 72% | |
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 7 Jul 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Greater Accra yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 16 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Greater Accra
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For irish potato in Greater Accra, 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.
The 2027 season in Greater Accra
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 909 mm in a typical farming district |
| Across its districts | From about 742 mm in the driest of 29 districts to about 1,019 mm in the wettest |
| 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 +0.5 °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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 57% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 258 growing days · about 930 mm · March to November |
|---|---|
| 27% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 276 growing days · about 1,000 mm · March to December |
| 12% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 248 growing days · about 860 mm · March to November |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 311 growing days · about 1,030 mm · February to December |

What it takes to grow irish potato in Greater Accra
| Planting material | About 47,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 51 kg per hectare |
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 89 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 | 110–185 days per hectare, by hand |
These are the nutrients a irish potato 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.
