What grows in Guelta Zerga
Setif, Algeria
The 2026/27 season in Guelta Zerga
| When the rains are expected | October 2026 to April 2027 |
|---|---|
| Rain in a typical year | About 515 mm |
| This season's rain | Rain close to usual — plan around about 515 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.4 °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, with a cool spell that slows winter growth |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 47% of this area. |
| 47% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 208 growing days · about 510 mm · October to April |
|---|---|
| 29% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 196 growing days · about 570 mm · September to May |
| 18% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 213 growing days · about 550 mm · September to May |
| 6% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 177 growing days · about 520 mm · September to December |

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.
What grows in Guelta Zerga with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it
The crops and dates above are read at cells spread across Guelta Zerga, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Guelta Zerga?
Beetroot, Garlic, Lettuce, Swiss chard, Chickpea all rate well in Guelta Zerga — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Beetroot in Guelta Zerga?
In Guelta Zerga the window for Beetroot runs 15 Sep 2026 to 7 Oct 2026.
Is there a farming app that works in Guelta Zerga?
Divisi does. It reads Guelta Zerga's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Guelta Zerga, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
