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 Sigowet/Soin is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sigowet/Soin
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 60% |
For lablab in Sigowet/Soin, the lie of the land is the tightest of the three at 60%. 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 Sigowet/Soin
| When the rains are expected | December 2026 to December 2026 |
|---|---|

| This season's rain | Rain close to usual — plan around about 1,237 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.8 °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 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 |

What it takes to grow lablab in Sigowet/Soin
| Nitrogen (N) | About 67 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 23 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.
