Alger, Algeria

| Fit | Favourable |
|---|---|
| When to plant | 10 Jun 2027 – 20 Jul 2027 opens in 36 weeks |
| Expected harvest | about 2.1 t/ha |
| Harvest | From 9 Aug 2027 to 17 Nov 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 50–105 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 10 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for El Biar 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 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in El Biar
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For cowpea in El Biar, the lie of the land is the tightest of the three at 60%. 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 2026/27 season in El Biar
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 730 mm |
| This season's rain | Leaning dry — January, February, November and December look 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 +1.1 °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 | This area is smaller than the climate grid can resolve, so it reads as one kind of ground. |
| 50% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 243 growing days · about 730 mm · September to May |

What cowpea needs to grow here
| Soil it likes | well-drained sand, sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 75 cm between rows, 25 cm between plants |

What it takes to grow cowpea in El Biar
| Planting material | About 90,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 126 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 46 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 50–105 days per hectare, by hand |
These are the nutrients a cowpea 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.
