When to plant Watermelon in Kerzaz
Bechar, Algeria
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.
| Fit | Favourable |
|---|---|
| When to plant | 22 Mar 2027 – 31 Mar 2027 opens in 25 weeks |
| Expected harvest | about 39.1 t/ha |
| Harvest | From 10 Jun 2027 to 19 Jul 2027, depending on the planting date |
| Ready to harvest | 80–110 days after planting |
| Work it takes | 46–96 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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kerzaz is close to normal, so these dates match the pattern the area usually follows.
Planting after 31 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| Nitrogen (N) | About 86 kg per hectare |

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.
