When to plant Papaya in Riaba
Bioko Sur, Guinea Ecuatorial
Papaya (pawpaw) is a fast, soft-stemmed tree you grow from seed.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 24 Jan 2027 – 20 Aug 2027 opens in 16 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 41.6 t/ha | about 60.1 t/ha |
| Work it takes | 106–218 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 9 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Riaba 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 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Riaba
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For papaya in Riaba, the lie of the land is the tightest of the three at 45%. 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 Riaba
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 2,572 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 +0.5 °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 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 70% of this area. |
| 70% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 352 growing days · about 2,600 mm · January to January |
|---|---|
| 27% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,680 mm · January to December |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,950 mm · January to December |

What papaya needs to grow here
| Soil it likes | well-drained sand, sandy loam or loam soil |

What it takes to grow papaya in Riaba
| Planting material | About 2,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 83 kg per hectare |
| Phosphate (P₂O₅) | About 19 kg per hectare |
| Potash (K₂O) | About 135 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 | 106–218 days per hectare, by hand |
These are the nutrients a papaya 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.
