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 10 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Milenge is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

| The soil | 76% |
| The lie of the land | 88% |

The 2026/27 season in Milenge
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to April 2027 |
| Rain in a typical year | About 1,163 mm |
| This season's rain | Rain close to usual — plan around about 1,163 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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 one full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 88% of this area. |
| 88% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 181 growing days · about 1,160 mm · October to April |
|---|---|
| 11% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 179 growing days · about 1,130 mm · October to April |

What it takes to grow yam in Milenge
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 47 kg per hectare |
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 72 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. |
These are the nutrients a yam 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.
