| When to plant | 15 Jan 2026 – 27 Sep 2026 closed for this season | same |
| Expected harvest | about 1.6 t/ha | about 1.1 t/ha |
| Harvest | From 25 Apr 2026 to 24 Feb 2027, depending on the planting date | |

| 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 30 Jan 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mvila leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 27 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mvila
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For lablab in Mvila, 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 Mvila
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 2,012 mm |
| This season's rain | Leaning dry — January looks short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.9 °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 that supports | enough rain for a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

Sloping ground holds back about 20% of yield here.
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 Mvila
| Nitrogen (N) | About 59 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 21 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.
