Sénégal

| Fit | Favourable |
|---|---|
| When to plant | 17 Nov 2026 – 26 Nov 2026 opens in 7 weeks |
| Expected harvest | about 32.4 t/ha |
| Harvest | From 15 Feb 2027 to 26 Mar 2027, depending on the planting date |
| Ready to harvest | 90–120 days after planting |
| Work it takes | 68–138 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 17 Nov 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Saint-Louis 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 26 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Saint-Louis
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For pumpkin in Saint-Louis, 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 2027 season in Saint-Louis
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | July 2027 to October 2027 |
| Rain in a typical year | About 281 mm in a typical farming district |
| Across its districts | From about 281 mm in the driest of 3 districts to about 306 mm in the wettest |
| This season's rain | Leaning dry — September 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 one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 88% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 250 mm · July to October |
|---|---|
| 11% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 81 growing days · about 320 mm · July to October |

What it takes to grow pumpkin in Saint-Louis
| Planting material | About 2,500 plants per hectare |
|---|---|
| Nitrogen (N) | About 81 kg per hectare |
| Phosphate (P₂O₅) | About 39 kg per hectare |
| Potash (K₂O) | About 130 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. |

These are the nutrients a pumpkin 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.
