When to plant Soybean in Tobruk
East, Libya
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 | Favourable |
|---|---|
| When to plant | 10 Feb 2027 – 30 Jun 2027 opens in 19 weeks |
| Expected harvest | about 4.0 t/ha |
| Harvest | From 11 May 2027 to 27 Nov 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 Tobruk is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow soybean in Tobruk
| Planting material | About 350,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 220 kg per hectare |
| Phosphate (P₂O₅) | About 60 kg per hectare |
| Potash (K₂O) | About 80 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.
