When to plant Groundnut in Rosfa
Setif, Algeria
Groundnut (peanut) is a low, leafy legume that does something no other crop in your field does: it flowers above the ground, but then each fertilised flower sends a little stalk — a peg — down into the soil, and the nut grows and fills underground.
| Fit | Moderate |
|---|---|
| When to plant | 11 Apr 2027 – 1 May 2027 opens in 27 weeks |
| Expected harvest | about 1.0 t/ha |
| Harvest | From 10 Jul 2027 to 28 Sep 2027, depending on the planting date |
| Ready to harvest | 90–150 days after planting |
| Work it takes | 71–126 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 11 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Rosfa is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rosfa
| Rain and temperature | 60% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For groundnut in Rosfa, the lie of the land is the tightest of the three at 45%. 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 season in Rosfa
| Rain in a typical year | About 361 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 361 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 | 4 kinds of ground. The season below is the largest that farms — about 64% of this area. |
| 64% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 115 growing days · about 370 mm |
|---|---|
| 23% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 151 growing days · about 330 mm · October to March |

What groundnut needs to grow here
| Soil it likes | well-drained sandy loam or sandy soil |

What it takes to grow groundnut in Rosfa
| Planting material | About 247,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 55 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 30 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 | 71–126 days per hectare, by hand |
These are the nutrients a groundnut 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.
