When to plant Irish potato in Baney
Bioko Norte, Guinea Ecuatorial
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 | 25 Jan 2026 – 20 Sep 2026 closed for this season | 2 Mar 2026 – 17 Nov 2026 |
| Expected harvest | about 29.5 t/ha | about 37.9 t/ha |
| Harvest | From 5 Apr 2026 to 28 Jan 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-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 11 Feb 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Baney 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 20 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Baney
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For irish potato in Baney, 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 2026 season in Baney
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 2,810 mm |
| This season's rain | Leaning dry — January looks 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 +0.6 °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 | 4 kinds of ground. The season below is the largest that farms — about 71% of this area. |

What it takes to grow irish potato in Baney
| Planting material | About 47,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 97 kg per hectare |
| Phosphate (P₂O₅) | About 30 kg per hectare |
| Potash (K₂O) | About 171 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.
