| Fit | Favourable | |
| When to plant | 16 Mar 2027 – 15 Apr 2027 opens in 24 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 21.9 t/ha | about 23.2 t/ha |

| Ready to harvest | 180–330 days after planting | |
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 26 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mopa-Muro 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 15 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Mopa-Muro
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to November 2026 |
| Rain in a typical year | About 1,118 mm |
| This season's rain | Leaning dry — September 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 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 95% of this area. |
| 95% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 243 growing days · about 1,120 mm · March to November |
|---|---|
| 5% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 236 growing days · about 1,090 mm · April to November |

What it takes to grow yam in Mopa-Muro
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 82 kg per hectare |
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 126 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.
