When to plant Watermelon in Gueni
LOGONE OCCIDENTAL, Tchad
Watermelon is a warm-season trailing vine, grown flat along the ground for its big, sweet, thirst-quenching fruit — a cousin of pumpkin, cucumber and melon.

| When to plant | 14 May 2027 – 22 Aug 2027 opens in 32 weeks | 21 May 2026 – 17 Nov 2026 |
| Expected harvest | about 35.0 t/ha | about 50.0 t/ha |
| Harvest | From 2 Aug 2027 to 10 Dec 2027, depending on the planting date | |

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 24 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Gueni is close to normal, so these dates match the pattern the area usually follows.
Planting after 22 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Gueni
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2027 to October 2027 |
| Rain in a typical year | About 948 mm |
| This season's rain | Rain close to usual — plan around about 948 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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 the largest that farms — about 94% of this area. |
| 94% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 167 growing days · about 950 mm · May to October |
|---|---|
| 6% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 165 growing days · about 920 mm · May to October |

What it takes to grow watermelon in Gueni
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 77 kg per hectare |
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 112 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 watermelon 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.
