When to plant Soybean in Hamma
Setif, Algeria
Soybean (Glycine max) is a bushy, knee-high bean grown for a seed that is rich in protein and oil — good to eat, good to sell, and it leaves the soil richer for whatever you plant next.
| Fit | Moderate |
|---|---|
| When to plant | 11 Apr 2027 – 20 Apr 2027 opens in 27 weeks |
| Expected harvest | about 1.2 t/ha |
| Harvest | From 10 Jul 2027 to 17 Sep 2027, depending on the planting date |
| Ready to harvest | 90–150 days after planting |
| Work it takes | 68–141 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 Hamma is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Hamma
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For soybean in Hamma, 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 season in Hamma
| Rain in a typical year | About 380 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 380 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 43% of this area. |
| 43% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 114 growing days · about 400 mm |
|---|---|
| 29% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 124 growing days · about 250 mm |

What soybean needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Rain it needs | About 600–1,500 mm across the season |

What it takes to grow soybean in Hamma
| Planting material | About 350,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 24 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 | 68–141 days per hectare, by hand |
These are the nutrients a soybean 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.
