| Fit | Favourable |
|---|---|
| When to plant | 1 Jan 2027 – 21 Jan 2027 opens in 13 weeks |
| Expected harvest | about 0.9 t/ha |
| Harvest | From 11 Apr 2027 to 20 Jun 2027, depending on the planting date |
| Ready to harvest | 100–150 days after planting |
| Work it takes | 75–156 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 21 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Hamraia is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What lablab needs to grow here
| Soil it likes | well-drained sand, sandy loam, loam, clay loam or clay soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 7.5 |
| Spacing | 75 cm between rows, 30 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow lablab in Hamraia
| Nitrogen (N) | About 33 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 12 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 | 75–156 days per hectare, by hand |
These are the nutrients a lablab 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.
