When to plant Eggplant in Collo
Skikda, Algeria
Eggplant (also called aubergine, brinjal or garden egg) is a bushy, warm-season cousin of tomato, potato and pepper — the nightshade family — grown for its glossy fruit: purple, white or green, round or long.
| Fit | Moderate |
|---|---|
| When to plant | 11 Apr 2027 – 30 Jun 2027 opens in 27 weeks |
| Expected harvest | about 18.4 t/ha |
| Harvest | From 9 Aug 2027 to 27 Dec 2027, depending on the planting date |
| Ready to harvest | 120–180 days after planting |
| Work it takes | 125–252 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 Collo 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 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Collo
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For eggplant in Collo, 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 2026/27 season in Collo
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 942 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 | 2 kinds of ground. The season below is the largest that farms — about 62% of this area. |
| 62% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 257 growing days · about 980 mm · September to May |
|---|---|
| 38% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 241 growing days · about 880 mm · September to May |

Sloping ground holds back about 65% of yield here.
What eggplant 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 | 90 cm between rows, 60 cm between plants |

What it takes to grow eggplant in Collo
| Planting material | About 20,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 55 kg per hectare |
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 92 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 | 125–252 days per hectare, by hand |
These are the nutrients a eggplant 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.
