When to plant Lettuce in Rahbat
Batna, Algeria
Lettuce is a fast, leafy salad crop grown for its crisp, tender leaves — and because people eat it raw, you must grow it clean.
| Fit | Moderate |
|---|---|
| When to plant | 22 Mar 2027 – 21 May 2027 opens in 25 weeks |
| Expected harvest | about 11.9 t/ha |
| Harvest | From 6 May 2027 to 4 Aug 2027, depending on the planting date |
| Ready to harvest | 45–75 days after planting |
| Work it takes | 40–80 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 1 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Rahbat is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rahbat
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 30% |
For lettuce in Rahbat, the lie of the land is the tightest of the three at 30%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The season in Rahbat
| Rain in a typical year | About 360 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 360 mm falling roughly when it always does |
| What that supports | enough rain for one short crop, and only if timed to it, cool for part of the year, so frost sets the planting date |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 56% of this area. |
| 56% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 117 growing days · about 390 mm |
|---|---|
| 22% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 150 growing days · about 310 mm · October to March |

What lettuce needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Spacing | 38 cm between rows, 30 cm between plants |
| Feed it most with | nitrogen, potassium and calcium |
What it takes to grow lettuce in Rahbat
| Nitrogen (N) | About 30 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 12 kg per hectare |
| Potash (K₂O) | About 60 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 | 40–80 days per hectare, by hand |
These are the nutrients a lettuce 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.
