When to plant Eggplant in Buba
Quinara, Guinea-Bissau
Eggplant (also called aubergine, brinjal or garden egg) is a bushy, warm-season cousin of tomato, potato and pepper — the nightshade family — grown for its glossy fruit: purple, white or green, round or long.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 10 May 2027 – 19 Jul 2027 opens in 32 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 30.7 t/ha | about 43.9 t/ha |
| Harvest | From 7 Sep 2027 to 15 Jan 2028, depending on the planting date | |
| Ready to harvest | 120–180 days after planting | |
| Work it takes | 125–252 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 30 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Buba is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Buba
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For eggplant in Buba, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026 season in Buba
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2026 to November 2026 |
| Rain in a typical year | About 1,855 mm |
| This season's rain | Rain close to usual — plan around about 1,855 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.9 °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 | 2 kinds of ground. The season below is the largest that farms — about 95% of this area. |
| 95% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 1,920 mm · May to November |
|---|---|
| 5% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 2,130 mm · May to November |

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

What it takes to grow eggplant in Buba
| Planting material | About 20,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 92 kg per hectare |
| Phosphate (P₂O₅) | About 26 kg per hectare |
| Potash (K₂O) | About 154 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 | 125–252 days per hectare, by hand |
These are the nutrients a eggplant 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.
